FINAL VAPOR INTRUSION STUDY REPORT FOR JOINT BASE ELMENDORF–RICHARDSON RESTORATION PROGRAM SITES, ALASKA
1.0 INTRODUCTION
This Vapor Intrusion (VI) Study Report has been prepared to document VI study activities conducted at Joint Base Elmendorf-Richardson (JBER) located in Anchorage, Alaska. This report has been prepared by HydroGeoLogic, Inc. (HGL) for the Air Force Civil Engineer Center (AFCEC) in accordance with the requirements of the 4P A-E Services Contract No. FA8903-08-D-8772, Task Order 0066.
1.1 SCOPE OF WORK
The scope of work includes the evaluation of the potential for one or more complete VI pathways associated with volatile organic compound (VOC) or fuel-related contaminants in groundwater or soil at 153 potential buildings of interest (PBOI) at JBER-Elmendorf (JBER-E) and JBER- Richardson (JBER-R). Figure 1.1 shows the location of the entire JBER installation, JBER-E, and JBER-R. The overall project scope of work includes the completion of an initial screening, on-site building surveys, field data collection, and human health risk assessment. Table 1.1 identifies the JBER Environmental Restoration Program (ERP) sites and their associated VI chemicals of interest (COI) included in the overall scope of work. Figure 1.2 provides a summary of the key tasks completed during the VI Study.
VI study sample collection and management, laboratory analysis, data verification, validation, and management were conducted according to the requirements of the final Uniform Federal Policy – Quality Assurance Project Plan (UFP-QAPP), Vapor Intrusion Studies for Joint Base Elmendorf – Richardson Restoration Program Sites, Alaska (U.S. Air Force [USAF], 2016). The groundwater sampling and reporting activities included in the UFP-QAPP are documented in the separate Final 1,4-Dioxane Groundwater Sampling Report for Joint Base Elmendorf– Richardson Restoration Program Sites, Alaska (May 2017) and are not discussed further in this report.
This VI study did not address all of the buildings known to overlie sources of VOC contamination in groundwater or soil at JBER, which could be associated with VI, as this study was conducted in response to remedy protectiveness questions of the Third Five-Year Review for Fort Richardson (February 2013) and Fourth Five-Year Review for Elmendorf Air Force Base (March 2014a). Separate investigations are underway to evaluate potential VI at other JBER sites and the results of these investigations will be discussed in separate reports.

2.0 BACKGROUND
The following sections present project background information for JBER including the regulatory history and physical setting.
2.1 JBER REGULATORY HISTORY
JBER is bounded by the Municipality of Anchorage to the south, Knik Arm to the north and west, and primarily undeveloped lands to the east. Most of the surrounding undeveloped land is part of Chugach State Park and the Chugach Mountain Range. The installation encompasses 74,000 acres of land, with elevations ranging from sea level along the Knik Arm shoreline to 3,800 feet above mean sea level in the Chugach Mountains to the south and east (see Figure 1.1).
2.1.1 Installation History
Fort Richardson was originally established with the signing of Executive Order 8102, Withdrawal of Public Lands for Use as Military Reservation, Alaska, by President Franklin D. Roosevelt on April 29, 1939, as part of the national defense buildup to World War II. This Executive Order established Elmendorf Army Airfield by changing the Federal land status from lands formally part of the Chugach National Forest to lands set aside for military purposes and uses and encompassed approximately 36,570 acres of land. Chugach National Forest was originally established by presidential proclamation in 1892 to provide for fish and wildlife habitat, forest products, and recreational and public uses including homesteading.
Subsequent Executive Orders (8343 and 8755) signed between 1939 and 1945 withdrew additional acreage from public use with approximately 151,180 acres of public land reclassified for military use. In 1950, approximately 9,042 acres of land was transferred to the Department of Air Force from the Department of Army for the establishment of Elmendorf Air Force Base (AFB).
Between 1945 and 1955, the military returned approximately 85,000 acres of land back to the Department of Interior as they were determined to be no longer needed for military purposes. Between 1955 and 1965, the Department of Army released back to the Department of Interior an additional 16,000 acres of land no longer needed for military uses. Since 1966, the boundaries of Elmendorf AFB and Fort Richardson have remained fairly stable.
Fort Richardson was comprised of an airfield complex and cantonment area with construction that started in 1941 from lands in the western portions of Chugach National Forest. With the passage of the National Security Act of 1947, which created the U.S. Department of Defense (DoD) and separated the Army Air Forces from the Army, the U.S. Air Force (USAF) became a separate service. In 1950, Fort Richardson was divided between the Army and the Air Force; the original cantonment area constructed during the early 1940s remained with the Air Force and became Elmendorf AFB. The Army established a new cantonment area approximately 4 miles to the east of the Elmendorf airfield complex on the northern part of the original installation as Fort Richardson. The reconfigured Elmendorf AFB consisted of approximately 9,000 acres
Air Force Civil Engineer Center 2-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
and the reconfigured Fort Richardson consisted of approximately 62,000 acres. Subsequent to the split of the installation in 1950, approximately 85,000 acres of land has been transferred or excessed to the Municipality of Anchorage or State of Alaska for non-military uses.
As a result of the 2005 DoD Base Realignment and Closure (BRAC) Commission recommendations, the former Elmendorf AFB and the former Fort Richardson were merged to form JBER. In July 2010, the 673d Air Base Wing (ABW) activated as the host wing, combining installation management functions of the Elmendorf AFB 3rd Wing and U.S. Army Garrison, Fort Richardson. Fort Richardson merged with Elmendorf AFB and became JBER on October 1, 2010.
2.1.2 Regulatory Background
The 1976 Resource Conservation and Recovery Act (RCRA) is one of the primary Federal laws governing the disposal of hazardous wastes. RCRA Section 3012 requires state agencies to inventory past hazardous waste disposal sites and provide information to the U.S. Environmental Protection Agency (USEPA) concerning those sites. In 1980, Congress enacted Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). CERCLA outlines the responsibility for identifying and remediating contaminated sites in the United States and its possessions. The CERCLA legislation identifies USEPA as the primary policy and enforcement agency regarding contaminated sites.
The 1986 Superfund Amendments and Reauthorization Act (SARA) extends the requirements of CERCLA and modifies CERCLA with respect to goals for remediation and the steps that lead to the selection of a remedial process. Under SARA, technologies that provide permanent removal or destruction of a contaminant are preferable to action that only contains or isolates the contaminant. SARA also provides for greater interaction with public and state agencies and extends the USEPA’s role in evaluating health risks associated with contamination. Under SARA, early determination of Applicable or Relevant and Appropriate Requirements (ARAR) is required, and the consideration of potential remediation alternatives is recommended at the initiation of a Remedial Investigation (RI)/Feasibility Study (FS). SARA is the primary legislation governing remedial action at past hazardous waste disposal sites.
Executive Order 12580, adopted in 1987, gave various Federal agencies, including DoD, the responsibility to act as lead agencies for conducting investigations and implementing remediation efforts when they are the sole or co-contributor to contamination on or off their properties.
To ensure compliance with CERCLA, its regulations, and Executive Order 12580, the DoD developed the Installation Restoration Plan (IRP) under the Defense Environmental Restoration Program (DERP) to identify potentially contaminated sites, investigate sites, and evaluate and select remedial actions for potentially contaminated facilities. DoD issued the Defense Environmental Quality Program Policy Memorandum 80-6 regarding the IRP in June 1980, and implemented the policies outlined in this memorandum in December 1980. The National Contingency Plan (NCP) was issued by USEPA in 1980 to provide guidance on a process by which (1) contaminant release could be reported; (2) contamination could be identified and quantified; and (3) remedial actions could be selected. The NCP describes the responsibility of
Air Force Civil Engineer Center 2-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Federal and state governments and those responsible for contaminant releases. The DoD formally revised and expanded the existing IRP directives and amplified all previous directives and memoranda concerning the IRP through Defense Environmental Quality Program Policy Memorandum 81-5, dated December 11, 1981. The memorandum was implemented by an Air Force message dated January 21, 1982.
The IRP is DoD’s primary mechanism for response actions on USAF installations affected by the provisions of SARA. In November 1986, in response to SARA and other USEPA interim guidance, the Air Force modified the IRP to provide for the RI/FS program. The IRP was modified so that RIs and FSs could be conducted as parallel activities rather than serial activities. The program now includes ARAR determinations, identification and screening of technologies, and development of alternatives. The IRP may include multiple field activities and pilot studies prior to a detailed final analysis of alternatives. Over the years, requirements of the IRP have been developed and modified to ensure DoD compliance with Federal laws, such as RCRA, NCP, CERCLA, and SARA.
2.1.3 National Priorities Listing
Elmendorf AFB and the Fort Richardson Army Post were placed on the CERCLA National Priorities List (NPL) in 1990 and 1994, respectively. The NPL is a list of national priorities among the known releases or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States and its territories. Both installations were listed “fence to fence,” which required comprehensive evaluation of all potential contaminated sites across the entire property. Both installations conducted exhaustive records research overseen by USEPA and Alaska Department of Environmental Conservation (ADEC) to determine all potentially contaminated sites or historical activities that were potential sources of contamination.
Subsequent to the NPL listing, and in accordance with applicable requirements of CERCLA, both installations were required to negotiate Federal Facility Agreements (FFA) with USEPA and ADEC that would become the legal framework to execute all future remedial cleanup activities on each respective installation. The FFAs provided legally enforceable stipulations that the installations were to comply with and also provided the installations the substance and structure to execute extremely complicated multi-year cleanup programs that considered all current and future regulatory requirements. Each installation negotiated and signed FFAs (“3- party agreements”) with both USEPA and ADEC. As NPL sites, both installations were required to establish cleanup programs that were regulated by USEPA under CERCLA authority and the State of Alaska under ADEC cleanup standards. Both installations were compelled to execute their respective cleanup programs in a judicious and competent manner that were negotiated with USEPA and ADEC, and included stipulated penalties for failure to meet the agreed to requirements or standards.
The FFA for Elmendorf AFB was signed in September 1991 by USAF, USEPA Region X, and ADEC. The FFA for Fort Richardson was signed by the Army, USEPA Region X, and ADEC in December 1994. The FFAs assigned sites to six operable units (OU) on Elmendorf AFB and five OUs on Fort Richardson, based on geographic proximity and similarity of contaminants;
Air Force Civil Engineer Center 2-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
complexity and size of source areas; affected media, potential for migration, exposure pathways, and receptors; and the availability of previously collected data to support remedy selection. The FFAs ensure that environmental impacts associated with past practices at each installation are investigated and appropriate actions are completed to protect human health and the environment. The FFAs also set deadlines, objectives, responsibilities, a procedural framework for cleanup, and set stipulated penalties for the failure to execute in a timely manner.
The six OUs at the former Elmendorf AFB are administered under CERCLA with USEPA oversight and are governed by the following Records of Decision (ROD):
• ROD, OU 1 (USAF, 1994); • ROD, OU 2 (USAF, 1995a); • ROD, OU 3 (USAF, 1997a); • ROD, OU 4 (USAF, 1995b); • ROD, OU 5 (USAF, 1995c); • ROD, OU 6 and Source Area SS19 (USAF, 1997b); and • ROD, DP98 (USAF, 2004).
The five OUs at the former Fort Richardson Army Base are administered under CERCLA with USEPA oversight, and are governed by the following RODs:
• ROD for OU A and B (U.S. Army, 1997); • ROD for OU C (U.S. Army, 1998); • ROD for OU D (U.S. Army, 2000); and • ROD for OU E (U.S. Army, 2005).
Several contaminated sites within JBER are the result of contamination related to petroleum spills and releases; however, provisions within CERCLA Sections 101(14) and 104(a)(2) exclude petroleum-related contamination from CERCLA hazardous substance regulation. Therefore, contaminated sites related to petroleum spills and releases within JBER are regulated by ADEC cleanup standards.
In October 1992, the State-Elmendorf Environmental Restoration Agreement was signed between Elmendorf AFB and ADEC. This cooperative agreement addressed the cleanup and restoration of sites with petroleum, oil, and lubricant (collectively referred to as petroleum, oil, and lubricant [POL]) contamination. USAF and ADEC later agreed the program reached the point where the agreement was no longer necessary and it was dissolved in October 2002. JBER- E now addresses the cleanup of any petroleum releases following 18 AAC 75 for contaminated sites, and 18 AAC 78 for underground storage tanks (UST).
The Army negotiated two separate agreements for POL cleanup at Fort Richardson; one focuses on areas contaminated with petroleum from USTs, and the other focuses on petroleum source areas not associated with USTs. The Army and ADEC signed the State-Fort Richardson Underground Storage Tank Compliance Agreement for USTs in 1993. This agreement defines the process by which the Army agreed to investigate and remediate petroleum-contaminated areas. The State-Fort Richardson Environmental Restoration Agreement for Non-UST Source
Air Force Civil Engineer Center 2-4 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Areas was signed in November 1994 for petroleum-contaminated source areas not associated with USTs. These two-party agreements guide how the Army was to perform necessary site assessments, monitor, remediate, and close petroleum-contaminated source areas not subject to CERCLA oversight.
As part of the formation of JBER, USAF assumed the responsibility to continue the cleanup of sites on former Fort Richardson under the agreements previously made between the regulatory agencies and the Army.
2.2 JBER PHYSICAL SETTING
The following sections summarize the climate, regional geology, surficial geology, hydrogeology, and surface water conditions for the JBER installation. Information regarding the geology and groundwater flow systems was obtained from the Draft 2014 Annual Field Activities Report, CERCLA Sites (USAF, 2015).
2.2.1 Climate
The JBER installation is located in a semi-arid area of south central Alaska; local and regional geographic features greatly affect climate in the area. Cook Inlet moderates the climate seasonally and four surrounding mountain ranges protect the area from Gulf of Alaska storms and extreme winter temperatures from the northern Alaska interior. Typical summer temperatures range from 46 degrees Fahrenheit (°F) to 65°F and winter temperatures range from 4°F to 45°F. Extreme temperatures range from -38°F to 86°F. Average precipitation in the Anchorage area is 15 inches, with a range from 13 to 20 inches. Most of the precipitation falls from July through September when the wind is from the southwest. Snowfall averages 66 inches, or about one-third (5.5 inches) of the total precipitation. The depth of snow on the ground does not normally exceed 24 inches.
2.2.2 Regional Geology
JBER straddles both the alluvial fan complex of the Anchorage plain and the moraine and glacial alluvium complex near the shoreline of Knik Arm. The gravel alluvium of the Anchorage plain underlies both the main cantonment area and the south training range complex. The northern portions of JBER are part of the Elmendorf Moraine complex that is made up of numerous east- west trending ridges that parallel Knik Arm. JBER is situated within the Eagle River and Ship Creek drainages along the Anchorage lowlands, a region of gently rolling terrain of glacial origin. East of the lowlands, the Chugach Mountains rise abruptly to elevations of 3,000 to 7,000 feet. The front escarpment of the Chugach Range, near Anchorage, is predominantly composed of meta-sedimentary and meta-volcanic rocks of the McHugh Complex. The lowlands are characterized by unconsolidated glacial, glacial-marine, and glacio-alluvial deposits of Quaternary age, which range from about 230 to 322 feet thick in the vicinity of JBER, and are underlain by Tertiary sedimentary bedrock of the Kenai Formation. The unconsolidated glacial deposits thicken in a westerly direction from the base of the Chugach Mountains and reach a thickness of 700 feet in the western area of Anchorage. Drilling logs indicate shale bedrock is

encountered at depths of approximately 260 to 300 feet in the vicinity of the JBER Groundwater Supply Wells, located near the Elmendorf Hospital Complex.
Glacial drift, hummocky moraine, and drumlin fields are some of the surficial glacial landforms present, particularly along the Chugach Mountain front. The Elmendorf Moraine, another prominent feature, parallels Knik Arm. The topography flattens in a west-southwesterly direction and is characterized by gently sloping, stratified outwash plain deposits associated with the Mountain View Fan. The Mountain View Fan extends from the mouth of the Eagle River Valley to downtown Anchorage and underlies a significant portion of JBER.
Glacial deposits are extremely variable due to the dynamic environment in which they are deposited. Multiple advances and recessions of ice, ice damming of melt water, interactions with nearby seawater, and the highly erratic behavior of glacial melt water streams are responsible for numerous depositional environments. Thus, the alluvial formations underlying the municipality of Anchorage and JBER are highly heterogeneous. Ship Creek flows northwest from the Chugach Mountains across the Anchorage lowlands and into Knik Arm of Cook Inlet. Most of the bedrock exposed along the northwest flank of the Chugach Mountains consists of heterogeneous assemblage of weakly metamorphosed clastic and volcanic rocks of the McHugh Complex. The McHugh Complex has been thrust over the rocks of the Valdez Group along the Eagle River fault several miles to the east. The Border Ranges Fault Zone, which marks the western limit of the Chugach Mountains, crosses Ship Creek to the west.
2.2.3 Surficial Geology
Elmendorf Moraine, the largest physiographic feature at JBER, bisects the installation in a northeast-to-southwest direction (see Figure 1.1). North of the Elmendorf Moraine, elevations decrease over a smoother surface ground moraine to the Six Mile Creek drainage, which flows westward into Knik Arm. South of the Elmendorf Moraine, a glacial outwash plain forms the southern portion of JBER-E. The Ship Creek drainage bisects JBER and flows westward from the headwaters located to the southeast in the Chugach Mountains north and west through the outwash plain to Knik Arm to the west.
The topography of JBER can be separated into three broad subdivisions that resulted from the last glaciation. These include the ridges that run northeast to southwest through the central portion of the base, forming the terminal moraine (Elmendorf Moraine); smooth-surfaced elongate hills, linear valleys, and small lakes that characterize the ground moraine north of the Elmendorf Moraine; and a broad surface of sand and gravel (the outwash plain) that extends southward from the Elmendorf Moraine. Soils on the moraines and over much of the outwash plain are shallow and well-drained. Depressions and shallow basins typically have poorly drained soils that include coarse, fibrous peat. In most places, the south slope of the Elmendorf Moraine is steep, whereas the north slope is gentle. There are many kettles (depressions) and kames (conical hills or short irregular ridges) on the moraine surface. Many of the kettles contain ponds and lakes, such as Triangle, Gwen, and Fish Lakes, while others contain bogs.
The ground moraine forms steep bluffs along Knik Arm where slopes range from 25° to 90°. Away from the Knik Arm, the surface is pitted with kettles and many drumlins (elongated gravel
Air Force Civil Engineer Center 2-6 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
hills parallel to glacial movement) that are oriented to the southwest. The ground moraine is an area of relatively low vertical relief, seldom exceeding depths of 50 to 75 feet below ground surface (bgs). Many of the kettles on the ground moraine are shallow depressions forming bog lakes or unfilled depressions, but some contain lakes such as Green, Spring, Otter, Clunie, and Hillberg Lakes.
The Bootlegger Cove Formation was deposited in this region via glacial outwash deposits and consists primarily of thinly bedded gray to light gray silt clay to clayey silt. The Bootlegger Cove Formation is a common aquitard and confining unit in the area. The ground moraine and the Bootlegger Cove Formation form an irregular surface upon which the younger alluvial sediments were deposited.
2.2.4 JBER-E Hydrogeology
The developed portion of JBER-E, including the airfield and supporting facilities, is located within the outwash plain to the south of the Elmendorf Moraine (see Figure 1.1). The soils of the outwash plain consist predominantly of sandy gravels and gravelly sands deposited by streams draining glaciers advancing out of the Knik and Matanuska valleys. The outwash varies in thickness across JBER-E, but tends to be relatively thin just south of the Elmendorf Moraine and increases to a thickness of up to about 60 feet near Ship Creek. Ship Creek, which flows roughly along the southern margin of JBER-E, has deposited an alluvial fan that overlies the outwash where the creek flows out of the Chugach Mountains to the east; it has eroded or incised into the outwash and deposited alluvial floodplain soils on top of the Bootlegger Cove Formation in its western reaches.
JBER-E is underlain by two aquifers: a shallow water table aquifer and a deeper, confined aquifer. The Bootlegger Cove Formation, which functions as an aquitard, separates the shallow water table aquifer from the deeper, confined aquifer across most of JBER-E. The shallow aquifer is not currently used as a water source on JBER-E. The deep aquifer serves as a secondary drinking water source for JBER-E, as well as for the Municipality of Anchorage when there is low stream flow. Water used on JBER-E is supplied from either Ship Creek or the deep aquifer. There is no communication between shallow and deep aquifers on JBER-E. Groundwater flow in the outwash plain is generally toward the south or southwest, while groundwater flow in the moraine areas is more variable depending on the specific location.
The hydraulic conductivity of JBER-E soils has been measured during many previous site investigations. The data show that the outwash soils, the glaciofluvial soils north of the Elmendorf Moraine, the Ship Creek alluvium, and the Ship Creek alluvial fan have relatively high hydraulic conductivity values, while the moraine has variable but significantly lower hydraulic conductivity values. In general, the Bootlegger Cove Formation may be characterized as having a very low hydraulic conductivity (although interbedded sand layers exist within the formation).
Across the airfield and main facility area south of the Elmendorf Moraine, the average depth to groundwater is approximately 26 feet bgs, with a minimum of approximately 0.9 feet bgs along Ship Creek and a maximum of approximately 53.6 feet bgs southeast of the airfield.
Air Force Civil Engineer Center 2-7 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Groundwater depths generally increase from west to east across JBER-E south of the Elmendorf Moraine.
Definitive data regarding groundwater temperatures across JBER-E are not available. An average groundwater temperature of 8 oC was determined to be appropriate for the purposes of the JBER VI Study during the project kick-off/scoping meeting conducted in June 2015, and documented in the UFP-QAPP.
2.2.5 JBER-R Hydrogeology
Although the developed portion of JBER-R (including the main cantonment and airfield areas) is also located south of the moraine, the surficial geology differs significantly from JBER-E (see Figure 1.1). The geology underlying JBER-R consists of glacial deposits, alluvial deposits, and metamorphic rock. The northern and central portions of JBER-R are made up of glacial sediments deposited in the Cook Inlet basin during a number of glacial periods. Alluvial deposits on the cantonment area are bounded by the Elmendorf Moraine to the northwest and metamorphic bedrock terrain to the southeast. Glacial outwash, alluvial fan, and fluvial deposits comprise the alluvial sediments that range from gravel in the eastern portion of the plain to sand in the southwestern portion. The cantonment area is composed of well-bedded deposits with well-sorted gravel.
The Mountain View Fan formation is a large alluvial fan that emanates from the Eagle River Valley and extends under the JBER-R main cantonment area. The Elmendorf Moraine borders the fan to the north while low hills that protrude through younger glacial sediment border the fan to the south. The fan slopes to the west-southwest and extends beyond the base. The fan was likely deposited by ice-marginal, glacially fed streams, based on its composition (stratified outwash) during outburst flooding events from ice-dammed lakes in the Eagle River Valley. Beneath the Mountain View Fan lie older glacial and glacio-marine deposits.
One shallow and one deep groundwater system have been identified in JBER-R, however, three separate aquifer systems exist in the cantonment area, including a shallow unconfined system, a locally confined system, and a deeper confined system. Ship Creek is the primary drinking water source for JBER-R and the deep aquifer serves as a secondary drinking water source. Three standby water supply wells supplement the surface water system with a maximum of two of the wells in use at a time during peak demand. The water source for the standby wells is a confined aquifer in the Knik outwash deposit. A drinking water well with a single service connection to the Otter Lake Recreational facility serves a transient population.
The shallow aquifer occurs under unconfined conditions in the Anchorage Plain deposits and in unconfined to semiconfined conditions in the till of the Elmendorf Moraine. Shallow perched groundwater of limited volume and extent exists in localized areas within the Elmendorf Moraine till deposits. Groundwater in the Anchorage Plain deposits occurs between 10 and 20 feet below ground surface (bgs). Flow in the Anchorage Plain is westerly along Ship Creek.
The next deeper aquifer system is approximately 80 feet bgs within the central part of the cantonment area. This aquifer changes from confined to semiconfined to unconfined, moving
Air Force Civil Engineer Center 2-8 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
from south to north across the cantonment area. Groundwater flow in the deeper aquifer is generally to the northwest. However, localized groundwater flow directions vary widely in the central part of the cantonment area, where the hydraulic gradient is shallower and discontinuous fine-grained units are present at depth.
The average depth to groundwater in the main cantonment area of JBER-R is approximately 81.8 feet bgs, with a minimum of approximately 70.2 feet bgs and a maximum of approximately 103.3 feet bgs (both located in the north-central portion of the main cantonment area). Groundwater depths generally increase from south to north across JBER-R.
Groundwater in the deep confined system is at its shallowest depths (130 feet bgs) in the northern area of JBER-R. The flow in the deep confined system is generally toward Knik Arm in a westerly to northwesterly direction, with a hydraulic gradient between 0.02 and 0.0025 foot per feet (ft/ft). The deep aquifer occurs under confined conditions beneath areas where the Bootlegger Cove Formation is present. Where the Bootlegger Cove Formation is discontinuous, the underlying aquifer is a leaky, confined system.
As described previously for JBER-E, definitive data regarding groundwater temperatures across JBER-R are not available. An average groundwater temperature of 8 oC was determined to be appropriate for the purposes of the VI Study during the project kick-off/scoping meeting conducted in June 2015, and documented in the UFP-QAPP.
2.2.6 Surface Water
The most significant stream channels within JBER include the Eagle River, Ship Creek, Six Mile Creek (including Upper and Lower Six Mile Lakes), and Chester Creek, all of which generally flow north and west through the ground moraine north of the cantonment areas.
The headwaters of Eagle River are at the base of Eagle Glacier located in the Chugach Mountains to the south and east of JBER. Eagle River passes through the eastern portion of JBER-R and generally flows to the north across the outwash plains, ground moraine, and terminal moraine before flowing into the Eagle River Flats estuary. Historical homestead documentation from the 1930s indicates the Eagle River Flats was a large grassy plain used for livestock grazing bisected by the various sub-channels of Eagle River before discharging into the Upper Knik Arm. Geological studies of the Eagle River Flats Impact Area indicated that the Eagle River Flats subsided 6 to 10 feet during the 1964 earthquake. Very few groundwater monitoring wells are located in the northern portion of the JBER-R training complex so there is little understanding of the influence that Eagle River has on the local groundwater.
The headwaters of Ship Creek are located to the south and east of JBER in Ship Lake to the west of the Eagle River drainage. Ship Creek is predominately fed by a combination of snow melt and numerous springs located along its course. Ship Creek passes through JBER-R prior to entering JBER-E and flows through the Alaska Railroad Terminal Reserve (an industrialized area) before discharging into the Knik Arm. Ship Creek has been impounded in various locations since 1912 as the water source for JBER and the municipality of Anchorage. Currently, JBER operates Ship Creek Dam, which provides raw water to the JBER-R Water Treatment Plant and remains an alternate raw water source for the municipality of Anchorage. Ship Creek is a gaining
Air Force Civil Engineer Center 2-9 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
water course until it enters the outwash plain downstream of Ship Creek Dam, where it becomes a losing water course. Ship Creek surface flow historically becomes subsurface between the western portion of JBER-R and the eastern portion of JBER-E during the winter months due to insufficient flow of water upstream of Ship Creek Dam. The gain in flow is suspected to result from groundwater flow exiting the outwash plain and bluffs located to the north and south of Ship Creek Valley.
Six Mile Creek flows within a relatively small watershed on the ground moraine in the northern portion of JBER-E. The headwaters are located near the JBER-E and JBER-R boundary and the creek flows west into Knik Arm. Two man-made lakes, Upper and Lower Six Mile Lakes, receive most of the drainage. The primary source of water in Six Mile Creek is a spring located on JBER-R to the west of Otter Lake.
The Chester Creek headwaters are located in the southern Davis Range area on JBER-R and the creek flows westerly from the Chugach Mountains across the outwash plain, entering the Knik Arm at Westchester Lagoon. Chester Creek is the predominant source of water located in the large wetland complex in the Davis Range area of the southern portion of JBER-R.

3.0 INITIAL SCREENING
The VI Study initial screening addressed a total of 153 buildings or structures identified as PBOIs and included the following primary tasks:
• Building location evaluation; • Building use evaluation; • Building design/construction evaluation; and • PBOI List.
The initial screening activities were conducted as described in the Final Letter Work Plan, Vapor Intrusion Studies for Joint Base Elmendorf-Richardson Restoration Program Sites (USAF, 2015b), hereinafter referred to as the Letter Work Plan.
3.1 BUILDING LOCATION EVALUATION
The objective of the building location evaluation was to identify candidate buildings and structures for inclusion in the VI Study PBOI List based on their location relative to a known or potential source for VI chemicals in groundwater or soil. Buildings addressed in the location evaluation are included in the JBER ERP as CERCLA (USEPA-regulated) or former petroleum/UST release (ADEC-regulated) sites.
Buildings identified as PBOIs were determined to be located within, or immediately adjacent to, one or more of the following spatial areas:
• Within a volatile organic compound (VOC) or Total Petroleum Hydrocarbon (TPH) groundwater contaminant plume boundary; • Within a 100-foot lateral buffer zone of a VOC groundwater contaminant plume boundary; • Within a 30-foot lateral buffer zone of a TPH groundwater contaminant plume boundary; and • Within a known or potential area of shallow soil contamination identified by JBER.
The use of the lateral buffer zones listed above is consistent with current USEPA and ADEC VI guidance. Sites identified by JBER with previously identified shallow soil contamination are associated with former petroleum/UST releases.
The location evaluation was conducted remotely using ArcGIS and the most recent available groundwater plume boundaries for VOCs and TPH provided by JBER, and geo-referenced aerial photographs taken in July 2013 and obtained from the U.S. Geological Survey (USGS) EarthExplorer website (http://earthexplorer.usgs.gov). The groundwater contamination plume boundaries were imported into ArcGIS as electronic shapefiles and were used to generate additional shapefiles for the VOC and TPH lateral buffer zones described above. The plume boundary and lateral buffer zone boundaries were then overlaid on the 2013 aerial photographs in ArcGIS, and applicable buildings and structures located within one or more of the target spatial areas were visually identified and recorded.
Air Force Civil Engineer Center 3-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
The location evaluation is considered to be a conservative approach because the specific construction of many of the buildings identified could not be confirmed using the aerial photographs alone. It was assumed that some of these structures would later be confirmed to consist of open-sided shelters or canopies not applicable for further evaluation in the VI Study. The specific construction of each PBOI was confirmed in the subsequent on-site building surveys discussed below.
Buildings located at restoration program sites associated only with shallow soil contamination (i.e., not located within any of the groundwater target spatial areas) were identified as PBOIs and included in the building surveys. In addition, JBER also identified several buildings as PBOIs, which are located between a groundwater target spatial area, and a restoration program soil contamination site as an additional conservative measure.
All of the buildings identified during the location evaluation were initially included in the draft PBOI List for further consideration during the remainder of the initial screening.
3.2 BUILDING USE EVALUATION
During the building location evaluation, the building use evaluation identified the initial assumed use of each PBOI. As described in the Letter Work Plan, each PBOI was assigned a current use of residential or commercial/industrial based on their location at JBER and their apparent general construction. Residential use is considered to include homes and dormitories (full time use). Commercial/industrial use is considered to apply to all other non-residential uses including offices, maintenance shops, aircraft maintenance, warehouses, and other workplaces at JBER. The commercial/industrial use designation also applies to recreational and community center facilities.
3.3 BUILDING DESIGN AND CONSTRUCTION EVALUATION
The design and construction of each PBOI was reviewed for applicable buildings where structural, architectural, or engineering design drawings were available. The objective of the design and construction evaluation was to supplement previous initial screening information regarding the applicability of individual PBOIs for inclusion in the building surveys. Several buildings were confirmed to be open structures not applicable to further consideration during the VI Study based on their design. A more detailed evaluation of available building design and construction drawings was conducted for the 30 BOIs identified for inclusion in the VI Study field data collection program. Available design drawings provided useful information regarding slab floor thickness and composition, and helped to identify features potentially associated with VI pathways (such as floor drains, utility conduits, and general floor plans). For some buildings, design drawings were obtained that also identified underground utilities within and adjacent to the structures. The number and type of drawings available for specific buildings varied greatly, and the newest buildings generally provided the most detailed information. Also, many of the older buildings at JBER have been remodeled or reconfigured numerous times from their original construction and the available information may not address all of the various alterations or represent current conditions.

3.4 POTENTIAL BUILDINGS OF INTEREST LIST
The PBOI List represents the complete inventory of buildings identified during the initial screening and subject to inspection during the subsequent on-site building surveys. The PBOI List represents a conservative starting point for scoping the VI Study field data collection program by including a relatively large number of structures potentially impacted by VI, based on their location relative to groundwater and/or soil contamination. The final PBOI List is presented in Table 3.1.
3.5 CHEMICALS OF INTEREST
The VI Study COIs identified for each project site were based on contamination previously identified in groundwater and/or soil. Site-specific COIs apply to indoor and outdoor air sample analysis at each BOI included in the field data collection program. All of the COIs, with the exception of gasoline range organics (GRO) and diesel range organics (DRO), are VOCs. The full list of VOCs and GRO will apply to soil gas sample analysis at all project sites.
For sites where GRO as identified as a COI, additional VOC compounds including benzene, toluene, ethylbenzene, and total xylenes (BTEX), and naphthalene also were considered to be COIs. By including the BTEX and naphthalene, a more conservative evaluation of ambient air conditions at the applicable BOIs (versus evaluating GRO alone) was provided. Additionally, the VOC compounds were analyzed using method TO-15 SIM, which provided lower detection limits than GRO, which could only be analyzed using method TO-15.
The site-specific COIs considered during the VI study are included in Table 1.1. More discussion of site-specific COIs and their respective laboratory analytical methods is provided in Section 6 of this report.

4.0 BUILDING SURVEYS
The on-site building surveys were conducted at JBER in October 2015 to confirm current conditions and gather additional information for each of the 153 buildings on the final PBOI List. In addition to providing the opportunity for detailed inspections of each PBOI, the building surveys also resulted in the elimination of a number of buildings due to their construction (open- sided canopies, shelters, etc.). Several other buildings were added or eliminated from the PBOI List due to their recent construction or demolition (i.e., not shown on the 2013 aerial photographs). These buildings were identified from available site maps, report figures, and recent aerial photographs. A summary of all buildings addressed during the building surveys is presented in Table 3.1, and includes the USAF Site Number, JBER building number, confirmed current use, the date of survey completion, and any applicable comments.
4.1 BUILDING SURVEY PROCEDURES
The building surveys were conducted according to the approach described in the Letter Work Plan. The primary components of the surveys included:
• Walk-through and visual inspection of accessible areas; • Building manager/supervisor interviews; • Chemical storage inventories; • Field screening data collection (indoor/outdoor air pressure, organic vapors); and • Identification of accessible areas for potential sub-slab/near-slab soil gas and indoor/outdoor ambient air sampling locations.
The surveys included the ground floor and basement (if applicable) of accessible areas in each building. Access to some portions of a few buildings was not possible during the surveys due to security or operational limitations, but general access during the entire survey mobilization was very good. Representatives from the JBER Bio-Environmental Engineer Flight provided escorts for the two HGL survey teams during most of the survey activities.
Each survey team collected field screening data using a Multi-Rae photoionization detector (total organic vapors) and an Extech Model SD700 electronic atmospheric instrument (indoor/outdoor air pressure manometer and ambient air temperature). Each team also collected digital photographs to document interior and exterior features of interest and general construction. The use of electronic field screening instruments or cameras was not allowed due to security requirements at several buildings (or portions thereof).
The performance of each building survey was guided by the completion of an ADEC Building Inventory and Indoor Air Sampling Questionnaire modified to include additional project-specific information. Although not all of the questionnaire items applied to every building, the forms served as templates to help maximize consistency and allow for the documentation of field screening measurements and logging of digital photographs. Completed building survey questionnaire field forms are provided in Appendix B of this report. In addition, many of the technical details or history associated with individual buildings were not known to the current building managers or supervisors due to their relatively short tenures at the facilities. USAF
Air Force Civil Engineer Center 4-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
personnel are regularly re-assigned or transferred and they generally do not remain at the same work location for extended periods.
4.2 BUILDING SURVEY COMPLETION STATUS
The following list summarizes the general status of the 153 PBOIs included in the PBOI List and the building survey:
• 93 commercial/industrial PBOIs confirmed to exist/survey completed; • 4 DP098 PBOIs confirmed to exist/survey not completed (no access); • 1 ST037 PBOI confirmed to exist/survey not completed (no access); • 20 ST037 Dallas Housing units confirmed to exist/survey not completed (no access); • 2 PBOIs confirmed as previously demolished; and • 33 PBOIs confirmed as temporary or open structures/survey not completed.
Of the 153 original PBOIs, two were identified as no longer existing and 33 PBOIs were identified as temporary or open structures. These 33 PBOIs were found to include Conex boxes, open-air equipment canopies, shelters, or temporary contractor storage structures; detailed surveys were not completed at these locations. None of these buildings were totally enclosed, heated, or regularly occupied and were not considered applicable for further evaluation in the VI Study. Building survey completion details for all 153 PBOIs are provided in Table 3.1.
Buildings at two sites were not surveyed due to lack of access during the field mobilization. The four buildings located at Site DP098 were not accessed due to high security communication operations at this facility. At Site ST037, Building 6266 (a warehouse located in the northern portion of the site) was not accessed due to the lack of a point of contact for building entry. Building 6266 is similar to six other adjacent warehouses used for warm or cold storage and the inability to survey this location is not considered to represent a significant data gap.
Although 20 Dallas housing residential units (southern portion of Site ST037) were identified as PBOIs during the building location evaluation, all of these units were occupied and were not accessible during the building surveys. A Silver Run Housing unit (Building 3752B) was identified by Aurora Military Housing during the building surveys to provide a general representation of similar units located in the Dallas Housing complex that were not accessible. Because the Silver Run unit was not included specifically in the VI Study, it is not included in Table 3.1 and is not discussed further in this report.
The lack of access to the buildings described above at Sites DP098 and ST037 during the building survey did not affect the outcome of the VI Study. Two buildings at Site DP098 and two units at the Dallas Housing complex were included in the field sampling program; the lack of access to these buildings during the building survey did not negatively impact field data collection planning.

4.3 BUILDING SURVEY FINDINGS
A detailed matrix of building survey findings is presented in Table 4.1 and is intended to summarize the relative potential for a complete VI pathway at each building surveyed. The matrix includes the following primary categories of building survey findings:
• Site-specific COI types for groundwater or soil contamination; • Relative proximity to the contamination source; • Current building use and occupancy; • Building lowest floor level; • Potential VI pathways; and • Organic vapor field screening results.
The objectives of the findings matrix are to provide a qualitative summary of the building survey findings and to rank the overall priority for each building surveyed relative to the potential presence of a complete or potentially complete VI pathway. The matrix includes a summary priority of “high,” “moderate,” or “low” for each of the primary categories listed above and for the overall VI potential for each building surveyed. Table 4.2 presents the lines of evidence and their associated rationale relative to the VI Study building priorities assigned in Table 4.1.
It is important to note the priority levels associated with VI potential are intended to support a qualitative comparison among all of the buildings addressed during the building surveys and are not intended to serve as quantitative indicators for potential VI. The qualitative comparison is necessary to prioritize the buildings for inclusion in the field data collection program based on the multiple lines of evidence developed through the completion of the initial screening and the building surveys. Each of the overall VI Study priorities are described in more detail in the following sections.
4.3.1 High Priority
A high VI Study priority was assigned to buildings with one or more of the following characteristics:
• Residential or recreational building use; • Lowest floor consisting of a basement, crawlspace, or skirted trailer; • Floor penetrations including a floor drain, sump, or in-floor oil/water separator; • Positive photoionization detector (PID) field screening readings and/or indoor air chemical odors not attributable to operations/stored materials; and • Active or passive radon detection or mitigation system.
A total of 65 high priority buildings were identified based on the above criteria and are highlighted in Table 4.1. Although recreational use building occupants are typically less exposed than residential or industrial use building occupants, the potential presence of children and/or infants in recreational use buildings determined their prioritization as “high” as a conservative measure.
Air Force Civil Engineer Center 4-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
4.3.2 Moderate Priority
A moderate VI Study priority was assigned to buildings with one or more of the following characteristics:
• Commercial/industrial building use with normal workplace occupancy (5- or 7-day workweeks); • Lowest floor consisting of ground-level or elevated dock-level asphalt or concrete floor; • Floor penetrations consisting of expansion joints, seams, or cracks; and • Positive PID field screening readings and/or indoor air chemical odors likely attributable to operations/stored materials.
A total of 12 moderate priority buildings were identified based on the above criteria and are highlighted in Table 4.1.
4.3.3 Low Priority
A low VI Study priority was assigned to buildings with one or more of the following characteristics:
• Commercial/industrial use with intermittent occupancy (less than a 5-day workweek); • No visible floor penetrations; and • No positive PID field screening readings and/or indoor air chemical odors.
A total of 20 low priority buildings were identified based on the above criteria and are highlighted in Table 4.1. Intermittent building occupancy represents less than a normal standard 5-day workweek. Specific durations beyond this level of detail can’t be identified due to the sporadic unscheduled use of many of the PBOI facilities (warehouses, cold storage, etc.).

5.0 BUILDINGS OF INTEREST
The following sections describe the selection of the 30 BOIs to be included in the VI Study field data collection program. The BOI evaluation addressed 118 of the PBOIs identified previously including the following:
• 93 commercial/industrial PBOIs confirmed to exist/survey completed; • 4 DP098 PBOIs confirmed to exist/survey not completed (no access); • 1 ST037 PBOI confirmed to exist/survey not completed (no access); and • 20 ST037 Dallas Housing units confirmed to exist/survey not completed (no access).
The PBOIs identified as BOIs for inclusion in the field data collection program were selected based on several criteria, including:
• High VI Study priority; • Availability of soil, groundwater, or soil gas characterization data from previous investigations; • Spatial location relative to groundwater contamination plume boundaries/buffer zones or soil contamination source areas; and • Professional judgement based on JBER ERP site-specific knowledge or recommendations.
Table 5.1 presents the BOIs selected for inclusion in the VI Study field data collection program, the applicable line(s) of evidence, and the associated selection rationale. The 65 high priority buildings represent the general overall pool of buildings from which the 30 BOIs were selected.
The following sections briefly describe the selection rationale and current conditions for each site and BOI included in the VI Study field data collection program. Unless otherwise noted, all of the buildings are normally occupied by adult males and/or females. Positive results for PID field screening, chemical odors, or other significant features are noted where applicable. A figure showing the site and BOI location is provided for each site and BOI. The BOI location figures also show the remaining non-BOI buildings addressed during the building surveys.
5.1 JBER-E BUILDINGS OF INTEREST

6.0 DATA QUALITY OBJECTIVES
This section presents the data quality objectives (DQO) presented in Worksheet #11 of the UFP- QAPP that apply to data collected during the VI Study field data collection program. The DQOs were developed using the systematic planning process described in Guidance on Systematic Planning Using the Data Quality Objectives Process (EPA QA/G-4) (USEPA, 2006). The USEPA DQO process includes the following seven primary steps:
1) State the problem; 2) Identify the goals of the study; 3) Identify information inputs; 4) Define the boundaries of the study; 5) Develop the analytic approach; 6) Specify performance or acceptance criteria; and 7) Develop the detailed plan for obtaining data.
The following sections describe the project DQOs for the VI Study field data collection program. All VI Study laboratory sample analyses were conducted by TestAmerica Laboratories, Inc. in Sacramento, California. Laboratory accreditations and certifications are provided in Appendix B of the UFP-QAPP.
6.1 STATE THE PROBLEM
The initial step of the DQO process consisted of summarizing the investigation objectives for which new environmental data were collected and analyzed.
The presence of documented soil or groundwater VOC contamination at multiple JBER ERP sites represents a potential source for VI to indoor air and potential risks to human health for building occupants. A widespread evaluation of potentially complete VI pathways and associated potential risks to building occupants has not been conducted at JBER to date. CERCLA requires a Five-Year Review to be conducted to ensure the remedies selected in a ROD are performing effectively and continue to be protective of human health and the environment.
Five of the 17 sites included in the VI field data collection program are currently included in CERCLA RODs at JBER-E or JBER-R (see Table 1.1 for OU designations). The remaining 12 sites are included due to the presence of subsurface VOC contamination in soil and/or groundwater beneath, or in close proximity to, existing occupied buildings. It was not known if the VI pathway was determined to be complete at any of the sites or buildings included in the VI Study. If the vapor intrusion pathway was determined to be complete, it was not known if concentrations in indoor air presented a risk to current building occupants/users. At multiple buildings, potential sources of VOCs in indoor air may be present due to building use (e.g., flammable storage cabinets, vehicle maintenance, solvent recovery apparatus) rather than VI.
Air Force Civil Engineer Center 6-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
6.2 IDENTIFY THE GOALS OF THE STUDY
The second step of the DQO process identified the study goals supported by the new data and analysis.
The study goals include determining if the VI pathway is complete for 30 existing buildings of interest; estimating the potential risk to human health associated with VI; and providing recommendations for further evaluation, if warranted.
The study goals supported the evaluation of remedy protectiveness for buildings at the five CERCLA sites and the identification of potentially complete VI pathways and associated risks to human health for the 12 sites not addressed in CERCLA RODs at JBER. The analytical results were initially evaluated by comparing maximum detections to health-based screening values. The screening values were based on a target cancer risk of 1 x 10-6 and non-cancer hazard quotient (HQ) of 0.1. Potential risks were characterized for buildings where analytes were detected in the indoor air samples regardless of whether the maximum detections exceeded the screening values. Using the maximum detected concentration in indoor air as the exposure point concentration, if an estimated cumulative cancer risk exceeds 1x10-4 and/or a noncancer Hazard Index (HI) exceeds a value of 1 for indoor air, then recommendations for further evaluation beyond the current risk assessment are included in this report.
Initially, indoor air sample results were compared to the action levels presented in Attachment A of the UFP-QAPP to identify the potential need for a response action by JBER at one or more BOIs. This comparison was conducted immediately after indoor air sample results were received from the laboratory and data validation was completed for each field sampling event. The potential indoor air response actions included Accelerated and Urgent (JBER), and ADEC Notification Levels. If an indoor air result exceeded a respective action level, the JBER Bioenvironmental Engineering Office (673 AMDS/SGPB) implemented their response action plan for the applicable BOI. The results of the preliminary screening are provided in Section 9 of this report.
Indoor air results also were compared to the applicable project screening levels identified in Table 9.4. The project screening levels include residential and commercial/industrial ADEC Indoor Air Target Levels based on a cancer risk of 1x10-5 or a HQ of 1, and USEPA Regional Screening Levels (RSL) for ambient air based on a cancer risk of 1x10-6 or a HQ of 0.1. The potential risk to human health associated with indoor air results at each BOI was quantified by conducting a risk assessment consistent with the requirements of USEPA Risk Assessment Guidance for Superfund Volume 1: Human Health Evaluation Manual (Part F, Supplemental Guidance for Inhalation Risk Assessment), Final, OSWER 9285.7-82 (USEPA, 2009). The risk assessment methodology and results are presented in Section 10 of this report.
Sub-slab and near-slab soil gas sampling results were compared to the applicable soil gas screening levels provided in Table 9.5. The project screening levels include ADEC Shallow or Sub-Slab Target Levels and values calculated using the USEPA Vapor Intrusion Screening Level (VISL) Calculator (modified to include June 2017 RSL toxicity values). The calculated VISLs are based on a cancer risk of 1x10-6 and non-cancer risk Total Hazard Quotient (THQ) of 1.
Air Force Civil Engineer Center 6-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
For any BOIs where indoor air conditions were determined to exceed a cancer and/or non-cancer human health risk target/threshold, a recommendation for additional evaluation was made (see Section 13 of this report).
6.3 IDENTIFY INFORMATION INPUTS
The third step of the DQO process identified the information needed to support the above study goals, including data gaps that warranted the collection of new information.
The necessary information inputs include the collection of sub-slab/near-slab soil gas, and indoor/outdoor air samples, at the 30 highest priority BOIs.
The default laboratory sample characterization approach at each BOI included the collection of four sub-slab soil gas samples, with near-slab soil gas samples substituted, if building conditions did not allow sub-slab access. Additionally, four indoor air and four outdoor air samples were included in the default characterization approach at each BOI. The total number of soil gas and indoor/outdoor air samples collected at each BOI varied depending on the overall building size, construction, or other features of interest. A detailed discussion and summary of the samples collected during the VI Study is presented in Section 7 of this report.
The necessary non-laboratory sample information inputs include additional lines of evidence collected during the VI Study at the 30 highest priority BOIs.
Additional lines of evidence that supported the VI Study evaluation at each BOI included evaluations of building location, use, and design and construction conducted during the initial screening. Potential buildings of interest and COIs also were identified. Building surveys were conducted to provide building-specific observations and field screening results to focus the VI Study and support the selection of the 30 highest priority BOIs for inclusion in the field data collection program. Additional field screening data were collected and observations made during each field sampling event.
6.4 DEFINE THE BOUNDARIES OF THE STUDY
The fourth step of the DQO process specified the spatial and temporal aspects of the environmental media or endpoints that the data were to represent to support the above study goals.
The VI Study includes lateral and vertical spatial boundaries for sub-slab/near-slab soil gas and indoor/outdoor air sampling. Temporal boundaries include two separate field sampling events to address potential seasonal variations, and a 24-hour collection duration for all samples.
Lateral spatial boundaries included building interiors for sub-slab soil gas and indoor air samples, and building exteriors (within 10 feet of exterior walls) for near-slab soil gas and outdoor air samples. Several vertical spatial boundaries applied to soil gas and air sampling including:
Air Force Civil Engineer Center 6-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
• Sub-slab soil gas sample points (floor corings were not extended into underlying soil/sub-base material); • Near-slab soil gas sample points (installed to total depths up to 10 feet bgs); and • Indoor/outdoor air samples (collected at approximately 5 feet above the floor/ground surface).
Temporal boundaries included the collection of indoor and outdoor air samples during an initial warmer weather period (late summer/early fall) and a second colder weather period (mid-winter) to address potential seasonal variations in soil gas migration and building interior heating/cooling system operation. Sub-slab and near-slab soil gas samples were only collected during the initial sampling event. Additionally, all ambient air and soil gas samples were collected using 6-liter Summa canisters with flow regulators to provide 24-hour composite samples.
6.5 DEVELOP THE ANALYTIC APPROACH
The fifth DQO step developed logical “if…then” statements that defined the conditions that informed the decision-maker to choose among alternative outcomes. Multiple decision rules applied to the VI Study field data collection program as presented below.
If an indoor air sampling result identifies an unacceptable risk to human health, then HGL will immediately notify JBER and AFCEC.
In addition to the preliminary screening of indoor air results described in Section 6.2, HGL immediately notified JBER and AFCEC if any indoor air sampling result identified one or both of the following during the development of the VI Risk Assessment: a chemical concentration greater than the respective ADEC Indoor Air Target Level (ADEC, 2012); or a human health estimated risk that exceeded one or both of the risk targets of 1x10-4 (cancer) and/or an HI value of 1 (non-cancer) for the inhalation exposure pathway. HGL made this notification based on either preliminary or final data regardless of the status of VI Study Report and VI Risk Assessment development to allow for an immediate assessment of building occupant safety. Indoor air sampling results were reviewed after each field data collection event.
If an unacceptable risk to human health due to VI is identified, then a recommendation for additional work will be made in the VI Study Report.
The identification of an estimated risk to human health, based on use of the maximum detected concentrations in indoor air for the COIs, exceeding pathway cumulative cancer risk of 1x10-4 and/or a HI of 1 at a BOI resulted in the development of one or more recommendations for additional work in this report (see Section 13).
If a significant data gap in the field data collection program is identified, then a recommendation for additional work will be made in the VI Study Report.
A data gap was considered significant if it prevented or negatively impacted the assessment of potential VI risk to human health at a BOI. A data gap associated with the usability or validity of an indoor air sample was likely to represent the most significant data gap during the field data
Air Force Civil Engineer Center 6-4 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
collection program, as these results directly represented the exposure to building occupants. Other less significant data gaps may have included, but were not limited to, potential interferences from non-VI air contamination sources and the need for additional soil vapor or indoor/outdoor air samples. The presence of potential or known data gaps were evaluated on a BOI-specific basis and are included in this report (see Section 13).
6.6 SPECIFY PERFORMANCE OR ACCEPTANCE CRITERIA
The sixth DQO step specified performance and acceptance criteria used to establish performance goals for limiting uncertainty in the data analysis. Multiple performance and acceptance criteria applied to the VI Study field data collection program as presented below.
Establish laboratory analytical method reference limits to ensure the sensitivity limits for reported concentrations are sufficient for comparison to project screening levels and for use in the VI Risk Assessment.
The project-specific analytical method reference limits and evaluation tables are presented in Worksheet #15 of the UFP-QAPP. Worksheet #15 tables include a list of analytical methods and parameters, associated sensitivity limits achievable by the laboratory, associated project screening levels, and the accuracy control limits (laboratory control sample [LCS]/laboratory control sample duplicate [LCSD] and matrix spike [MS]/matric spike duplicate [MSD] recoveries). The project screening levels consist of the Indoor Air Target Levels (Appendix D) and Shallow or Subslab Soil Gas Target Levels (Appendix E) in the ADEC VI guidance (ADEC, 2012) and RSL (USEPA, 2016) as summarized in this report (Table 9.4 for indoor air and Table 9.5 for soil gas) for the applicable site-specific COIs and human health risk receptors.
Specify laboratory analytical data QC acceptance criteria for laboratory evaluation of all results to ensure data quality and future usability of field sampling results.
Laboratory analytical data quality control (QC) acceptance criteria are documented in Worksheet #12 of the UFP-QAPP. The QC acceptance criteria were used by the laboratory to evaluate analytical data quality, identify QC discrepancies and applicable corrective actions, and address systematic issues that may have affected data usability.
Identify data validation and usability assessment requirements to determine if laboratory analytical data are of sufficient quality for use in definitive or screening-level evaluations.
Requirements associated with data validation (Worksheets #35 and #36) and data usability assessments (Worksheet #37) are also provided in the UFP-QAPP. Data validation was performed for 100 percent (%) of the soil gas and indoor/outdoor air analytical results generated during the VI Study. The data usability assessment includes an evaluation of the QC elements relating to precision, accuracy, representativeness, comparability, completeness (sample collection and analytical), and sensitivity (PARCCS). The impact of any data gaps resulting from sampling incompleteness or rejected data are evaluated in this report. Definitive quality data were required for use in the indoor air concentration screening and the VI Risk Assessment. If any results were determined to represent screening-level data quality only, they may still be

useful in the overall VI Study (depending on the specific data quality issues identified) but were not used in quantitative evaluations.
6.7 DEVELOP THE DETAILED PLAN FOR OBTAINING DATA
The seventh DQO step identified the most resource-effective sampling and analysis design for generating the information needed to satisfy the DQOs. The overall scope of the VI Study field sampling program included the following:
• Sub-slab or near-slab soil gas – average of four samples per BOI; • Indoor air – average of four samples per BOI; and • Outdoor air - average of four samples per BOI.
Field duplicate QC samples were collected at a frequency of 1 per 10 regular samples per base for each of the sample matrices listed above. For soil gas and ambient air sampling, no more than one field duplicate sample was collected from each matrix per BOI. A summary of planned samples versus actual samples is provided in Table 7.2 (JBER-E sites) and Table 7.4 (JBER-R sites). Soil gas samples were analyzed for the full list of VOCs and GRO using USEPA Method TO-15. Indoor and outdoor air samples were analyzed for the site-specific COIs using USEPA Method TO-15 selective ion monitoring (SIM) and GRO using Method TO-15 (where applicable). The lower reporting limits associated with Method TO-15 SIM were necessary to meet the required project screening levels for VOCs in residential indoor air (see Table 9.4).
All samples were collected for a duration of 24 hours using pre-cleaned, certified, and flow- regulated 6-liter Summa canisters. Summa canisters associated only with method TO-15 for soil gas were batch-certified and Summa canisters associated with Method TO-15 SIM were individually certified by TestAmerica prior to use. For sites with COIs that included one or more VOCs and GRO, the GRO analysis were conducted on the Method TO-15 SIM certified Summa canister using Method TO-15. None of the Summa canisters were certified for GRO, although they were cleaned and prepared according to the same batch certification process applied to analysis for VOCs by method TO-15.
Sub-slab and near-slab sample collection included the use of a helium leak detection system prior to the start of sample collection. A helium concentration greater than 10% (by volume) was considered to indicate a compromised surface seal at the soil gas sample point and the sampling system was checked and re-tested until acceptable.
In general, soil gas and indoor air sample locations were biased to portions of buildings with higher occupancy or traffic (as allowed by operational limitations). VI Study samples also were biased to areas where sensitive receptors were or may have been present, or where other features potentially associated with a VI pathway were present, where applicable. By default, BOI interior soil gas samples were collected from sub-slab locations. If sub-slab access was not possible within one or more individual sample locations at a BOI, then these soil gas samples were collected from adjacent near-slab locations. Indoor and outdoor air samples were collected using a Summa canister tubing intake suspended at approximately 5 feet above the floor/ground surface to represent the breathing zone. The use of a helium leak detection system did not apply
Air Force Civil Engineer Center 6-6 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
to indoor or outdoor air samples. The sample tubing intake height for crawlspace air samples was approximately 1-2 feet above the ground surface.
VI Study sampling and reporting activities are compliant with the applicable requirements of 18 AAC 75.333. VI Study sampling was supervised by a “Qualified Environmental Professional” per the regulations. The resume for each member of the field team is provided in Appendix G of the UFP-QAPP.
The sub-slab, near-slab soil gas and indoor/outdoor air sampling methods, including the helium leak detection system, are described in more detail in Worksheet #21 of the UFP-QAPP and in the task-specific standard operating procedures (SOP) provided in Appendix A of this report. A description of the BOI-specific sampling plan, rationale, and completed sample collection is provided below. The summaries also describe any discrepancies between the planned and actual field sampling completed.

7.0 FIELD DATA COLLECTION SUMMARY
The following sections describe the field data collection activities completed at JBER-E and JBER-R during the VI study.
7.1 FIELD SAMPLING PROGRAM IMPLEMENTATION
The following sections describe soil gas and air sampling methods associated with the field data collection program. The field data collection SOP associated with each of the VI study sample types are provided in Appendix A of this report. The SOPs include detailed descriptions of the sampling procedures and photographs/schematic drawings of each sampling system and their primary components.
The field data collection program was conducted during two separate mobilizations. FSE1 was conducted from July 25, 2016 through October 7, 2016. FSE2 was conducted from January 23, 2017 through February 10, 2017.
7.2 GENERAL IMPLEMENTATION
7.2.1 Field Staffing
HGL anticipated using two field teams, consisting of two people each, to conduct field data collection activities. The actual field staffing plan used one field team of three people during FSE1 due to the complexity of soil gas leak detection testing and the general amount of equipment handling required. One team of two people was used during FSE2. Per the UFP- QAPP, VI sampling activities were compliant with the applicable requirements of 18 AAC 75.333. VI sampling was supervised by a “Qualified Environmental Professional,” who also conducted laboratory sample management and coordination.
HGL used an off-site field staging area (FSA) to store field equipment and supplies during the field data collection mobilizations. The FSA consisted of a rented self-storage locker located at Best Storage at 405 Boniface Parkway (approximately 1 mile south of the JBER Boniface Gate). The off-site location provided unlimited access for the project field teams and the TestAmerica courier for delivery and pickup of air sample Summa canisters and supplies throughout the FSE1 and FSE2 mobilizations.
7.2.2 VI Sample Duration
All soil gas and ambient air samples were collected concurrently at each BOI for a duration of 24 hours using flow-controlled Summa canisters. Each Summa canister was cleaned and certified by the laboratory prior to delivery to HGL for use. Any canister with visible damage or an initial vacuum reading outside acceptable limits was visibly tagged, taken out of service, and returned to the laboratory.
Sample collection did not begin until at least 24 hours after soil gas sampling point installation, to allow the subsurface to equilibrate to pre-installation conditions. Although sampling was not to begin until at least 48 hours after a rain event greater than 1 inch, no precipitation events of
Air Force Civil Engineer Center 7-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
this magnitude occurred during either field mobilization. The completion of field sampling activities at the 30 BOIs was scheduled according to operational, technical, and logistical requirements. The overall duration of the FSE1 mobilization was extended due to the process of obtaining an approved dig permit taking longer than anticipated. An approved dig permit was required (and obtained) for all soil gas sample points prior to installation.
7.2.3 Atmospheric Conditions and Ambient Air Monitoring
Atmospheric conditions were measured at the start and end of the sample collection period at all VI sampling locations. Ambient air conditions were documented for air pressure, temperature, and relative humidity using an Extech SD700.
Outdoor weather conditions, including precipitation totals and wind direction/speed, were obtained from the Weather Underground website (https://www.wunderground.com/cgi- bin/findweather/getForecast?query=PAED). Weather station PAED, located at the JBER-E airfield, was the station used for project data. Differential air pressure measurements (sub-slab versus interior ambient air) were collected at each sub-slab soil gas sample location using an Extech PS106 prior to the start of, and after the completion of, sample collection. Table 7.1 presents a summary of the differential air pressure measurements for sub-slab soil gas sample locations. The differential air pressure measurements are described as a “downward” gradient (i.e., positively pressurized interior), an “upward” gradient (i.e., negatively pressurized interior), or a “neutral” gradient (i.e., no difference in air pressure).
The field teams used a Multi-Rae portable PID to identify and document the presence of organic vapors at each sampling location. The field teams also attempted to confirm previous positive field screening results from the building surveys, as these data are included in the rationale for specific sampling locations at applicable BOIs. Each field team also recorded a detailed inventory of organic chemicals used or stored at each BOI that may represent a potential source for indoor or outdoor air organic vapors. Building survey observations indicated that many buildings include flammable chemical storage cabinets or other chemical storage areas, some associated with positive PID field screening results.
In an attempt to identify and/or limit, to the extent possible, potential sources for VOCs that may interfere with VI sampling, a pre-sampling inspection was conducted at each BOI. Because the soil gas sampling points were to remain in place for at least 24 hours after installation/prior to sampling to allow for subsurface conditions to equilibrate, the pre-sampling inspections were conducted at the time of soil gas sampling point installation. The pre-sampling inspections also provided the field teams with an opportunity to coordinate sampling activities and identify potential logistical issues with building personnel.
7.2.4 VI Sample Documentation
Field log forms were used during the field sampling events to ensure consistent documentation of field procedures and observations. The forms included a field form for general building information, and checklists for sub-slab soil sampling, near-slab soil gas sampling, and ambient air sampling.
Air Force Civil Engineer Center 7-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
One general building information form was completed for each BOI, and the remaining checklists were completed as applicable to the number of each type of sample collected at each BOI. A pre-sampling building walk-through was conducted at each BOI to identify preferred soil gas sample locations as part of the dig permit approval process prior to sample port installation. Completed field sampling checklists for FSE1 and FSE2 are provided in Appendix B of this report.
Each individual sampling location was identified spatially by measuring the distance between the sampling location and at least two adjacent permanent structural features for future reference, if needed. The use of a field global positioning system was not possible due to the location of samples inside, or directly adjacent to, exterior walls. The sample location measurements were used to generate spatial location coordinates that were subsequently used to develop the sample location figures in Sections 11 and 12 of this report, and to satisfy Environmental Resources Program Information Management System (ERPIMS) data reporting requirements.
A digital photograph was taken for each sampling system setup during FSE1 to show the system components and the general location setting to include surrounding features. Digital photographs were not taken during FSE2 because the sampling locations were the same as those used during FSE1. Representative digital photographs of VI sampling equipment and operations are provided in Appendix C of this report.
7.2.5 VI Sampling Equipment Protection
Each soil gas and ambient air sampling location setup included traffic safety cones and emergency contact signage while in place. A laminated sign was placed at each sampling location and included on-site contact information for HGL. Wherever possible, soil gas and ambient air sample locations were selected to avoid high-traffic areas and to minimize disturbance to ongoing facility operations. HGL coordinated with JBER and each BOI manager prior to, during, and after sampling to facilitate field data collection activities and minimize the potential for damage to sampling equipment.
The only damage to sampling equipment during the VI study occurred at Building 7309 during FSE1. Two sub-slab soil gas sample ports were damaged during physical training activities after installation but prior to the start of sample collection. Upon discovering the damage, the sample ports were replaced and sampling at the building was delayed 24 hours to allow for subsurface equalization. No other sampling equipment was damaged or interfered with during the FSE1 or FSE2 field mobilizations.
7.3 FIELD SAMPLING PROCEDURES
The following sections summarize the field sampling procedures for ambient (indoor, outdoor, or crawlspace) air and soil gas sampling conducted during the VI study. All ambient air samples were analyzed by the laboratory for site-specific COIs using USEPA Method TO-15 SIM (VOCs) and Method TO-15 (GRO only), where applicable. All soil gas samples were analyzed for the full list of VOCs and GRO using Method TO-15. For sites where GRO was included as a COI, the TO-15 SIM Summa canisters were also used for the TO-15 GRO analyses.
Air Force Civil Engineer Center 7-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
The preliminary target locations for ambient air and soil gas samples provided in the UFP-QAPP were often relocated due to field conditions or operational requirements at each BOI. The actual VI sample locations are shown in the figures in Sections 11 (JBER-E) and 12 (JBER-R) of this report.
7.3.1 Ambient Air
Indoor and outdoor air samples were collected using 24-hour flow-regulated Summa canister samples concurrent with soil gas samples collected at each BOI during FSE1. One collocated indoor air sample was collected adjacent to each sub-slab soil gas sample location to allow for comparison between the two sample results. Also, one ambient air sample was collected from within each accessible crawlspace/trailer skirt at applicable BOIs. The Ambient Air Sampling SOP is provided in Appendix A of this report.
Indoor and outdoor air sample Summa canisters were collected from tubing suspended approximately 5 feet above the floor/ground surface using a fiberglass rod. Crawlspace air samples were collected directly into the Summa canister flow controller (no tubing) where access allowed, otherwise sample tubing was extended into the crawlspace for sample collection. Summa canister shut-in tests were performed prior to sample collection as described previously for the sub-slab sampling method. No other leak testing or pre-sample purge activities applied to ambient air sampling, as the flow controller inlet (or tubing) represented the air sampling point.
Similar to soil gas sampling, all required sampling systems were set up and tested as needed, and then all soil gas and ambient air samplers were initiated within a few minutes’ time by the field team at each BOI. At the end of the 24-hour sampling period, all sample canisters were closed and retrieved for shipping to the analytical laboratory.
7.3.2 Soil Gas
Soil gas samples were collected using a sub-slab or near-slab method, depending on access to the required sample locations and conditions at each BOI. Each of the soil gas sampling methods is described in the following sections. Soil gas sampling SOP are provided in Appendix A of this report. Complete field sampling checklists are provided in Appendix B.
7.3.2.1 Sub-Slab Soil Gas Sampling
The sub-slab sampling method was the intended default for soil gas characterization at BOIs where suitable access to the required locations was allowed. The purpose of sub-slab sampling was to characterize soil gas present beneath the building floor that represented a potential source for VI to indoor air.
Sub-slab samples were collected using a sample port installed through a concrete slab floor located within a building’s interior. Leak detection testing (including the use of helium as a tracer gas) and a pre-sampling system purge, were conducted for each near-slab sampling system prior to sample collection. Soil gas samples from sub-slab locations were collected for a duration of 24 hours using laboratory cleaned and certified stainless steel Summa canisters. The sample

ports were removed and the floor coring abandoned using vinyl cement after the completion of sample collection at each location.
Approved written utility clearance was obtained through the completion of a JBER Civil Engineer Work Clearance Request form (aka dig permit) and compliance with HGL SOP 401.01 Subsurface Utility Avoidance (see Appendix C of the UFP-QAPP) prior to the installation of each sub-slab sample point. Approved dig permits are included in the field forms provided in Appendix B of this report.
7.3.2.2 Near-Slab Soil Gas Sampling
Near-slab soil gas samples were collected adjacent to building exterior walls to replace inaccessible sub-slab sample locations or at BOIs where sub-slab samples were not possible. Near-slab sampling points were located within approximately 10 feet from the applicable building exterior wall where access and underground utility clearance allowed. The near-slab soil gas sampling method was nearly identical to the sub-slab approach described above, with the primary difference being the use of a subsurface sampling point in place of a floor coring (see Appendix A).
Near-slab sample points were installed using a DPT drill rig and consisted of Schedule 40 polyvinyl chloride (PVC) construction. The sampling points included screened intervals of 1 to 2 feet and were installed to depths up to 10 feet bgs. Near-slab sampling points did not extend into groundwater. Undisturbed soil cores were examined to identify the most suitable screened interval depth at each location.
Leak detection testing (including the use of helium as a tracer gas) and a pre-sampling system purge were conducted for each near-slab sampling system prior to sample collection. Soil gas samples from near-slab locations were collected for a duration of 24 hours using laboratory cleaned and certified stainless steel Summa canisters. The sampling points were removed and the soil borings abandoned using granular bentonite after the completion of sample collection at each location. Cold asphalt patch was used to seal the upper 6 inches of borings completed through asphalt pavement. Similar to sub-slab floor coring, approved written utility clearance was obtained through the completion of a written approved dig permit. Approved dig permits are included in the field forms provided in Appendix B of this report.
7.4 JBER-E SITES SAMPLING DESIGN AND RATIONALE
The following sections describe the site- and BOI-specific VI sampling design and rationale, sampling completed during FSE1 and FSE2 for JBER-E, and any changes in the sampling approach from the UFP-QAPP. Table 7.2 provides a summary of the samples collected at each JBER-E site and BOI (including field duplicate samples). Table 7.3 provides the spatial location coordinates for the JBER-E field samples. Figures showing the completed VI sample locations (and sample results) are provided in Section 11 and are referenced for each site and BOI described below.
Air Force Civil Engineer Center 7-5 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
7.4.1 Site CG704
7.4.1.1 Building 8691
Planned sampling at Building 8691 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. The interior samples were generally located in the southern portion of the building, as this area is located closest to the groundwater contamination plume boundary. TCE is the only COI at this site.
Actual sampling at Building 8691 generally followed the planned approach, but with modifications due to field conditions encountered during sampling. A total of four soil gas/ambient air sample pairs and three additional ambient air samples were collected. During FSE1, two collocated indoor air/sub-slab sample pairs were completed as planned in the southern portion of the building. The two collocated indoor air/sub-slab sample pairs planned for the interior shop area were changed to outdoor air/near-slab sample pairs located along the northern exterior wall due to operational limitations. Also, only one outdoor air sample was collected along the southern exterior wall due to a shortage of Summa canisters at the end of the FSE1 mobilization. Priority for available Summa canisters was applied to indoor air samples to support the risk assessment. A field duplicate planned for Building 8691 ambient air also was not collected during FSE1 due to the shortage of Summa canisters at the end of the field mobilization (a cross-threaded flow controller did not pass the canister shut-in test was not usable). During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.1.
7.4.2 Site DP098
7.4.2.1 Building 18220
Planned sampling at Building 18220 included a modified approach of four sub-slab soil gas/indoor air sample pairs in the basement, three indoor air samples on the first floor, and four outdoor air samples. COIs at Site DP098 include 1,1-DCE, cis-1,2-DCE, PCE, TCE, and vinyl chloride.
Actual sampling at Building 18220 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs (basement), three indoor air samples (first floor), and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.3 (ground floor) and Figure 11.4 (basement).
7.4.2.2 Building 18224
Planned sampling at Building 18224 included the default approach of four sub-slab soil gas/indoor air sample pairs (one in the basement mechanical room) and four outdoor air samples. COIs at Site DP098 include 1,1-DCE, cis-1,2-DCE, PCE, TCE, and vinyl chloride.
Actual sampling at Building 18224 generally followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were
Air Force Civil Engineer Center 7-6 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
collected. The sub-slab soil gas/indoor air sample pair originally planned for the basement mechanical room was moved to the first floor because the mechanical room was flooded. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.6.
7.4.3 Site FT023
7.4.3.1 Building 17534
Planned sampling at Building 17534 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One interior location was biased to a floor drain in the northeastern portion of the building (due to a PID detection during the building survey), and another was biased to a long floor drain in the southern portion of the main hangar. COIs at the FT023 site include 1,1-DCE, 1,1,1-TCA, benzene, cis-1,2-DCE, PCE, and TCE.
Actual sampling at Building 17534 followed a modified approach due to conditions encountered at the building. During FSE1, it was discovered that an in-floor heating system was present in the building interior, therefore the four sub-slab soil gas/indoor air sample pairs were changed to near-slab soil gas/outdoor locations. The planned outdoor air samples were moved to the building interior. A total of four near-slab soil gas/outdoor air sample pairs and four indoor air samples were collected during FSE1. The indoor air sample planned for the parts cleaning room was moved to the open hangar area. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.8.
7.4.4 Site SD029
7.4.4.1 Building 16716
Planned sampling at Building 16716 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. Sample locations were generally biased to the southern half of the building due to the proximity of the groundwater contamination plume boundary. One interior location is biased to a long floor drain in the southwestern portion of the south hangar. COIs at the SD029 site include PCE and TCE.
Actual sampling at Building 16716 generally followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. The sub-slab soil gas/indoor air sample pair originally associated with the hangar floor drain was moved to the southwestern corner of the hangar due to operational concerns. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.10.
7.4.5 Site SS022
7.4.5.1 Building 12755

the building were observed during the building surveys but no specific potential source was identified. TCE is the only COI at the site.
Actual sampling at Building 12755 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.12.
7.4.6 Site ST032
7.4.6.1 Building 13272
Planned sampling at Building 13272 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One interior sample location was biased to a floor drain in the garage. COIs at the ST032 site include BTEX, GRO, and naphthalene.
Actual sampling at Building 13272 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.14.
7.4.7 Site ST036
7.4.7.1 Building 27369
Planned sampling at Building 27369 included a modified approach of three sub-slab soil gas/indoor air sample pairs in the basement, one indoor air sample on the first floor, and four outdoor air samples. Basement sample locations were generally biased to the southwestern portion of the building due to the presence of the adjacent soil contamination area. TCE is the only COI at the site.
Actual sampling at Building 27369 followed the planned approach. During FSE1, a total of three sub-slab soil gas/indoor air sample pairs (basement), one indoor air sample (first floor), and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.16 (ground floor) and Figure 11.17 (basement).
7.4.8 Site ST037 North
7.4.8.1 Building 6211
Planned sampling at Building 6211 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One interior location was biased to the western portion of the building and the second location was biased to a floor drain in the southern portion of the building (associated with a PID detection observed during the building surveys). TCE is the only COI at the site.
Air Force Civil Engineer Center 7-8 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Actual sampling at Building 6211 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.19.
7.4.8.2 Building 7228
Planned sampling at Building 7228 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One interior location was biased to a floor drain located in the central portion of the building and a second location was biased to a floor drain in the northeastern portion of the building (both associated with PID detections observed during the building surveys). TCE is the only COI at the site.
Actual sampling at Building 7228 followed a modified approach due to conditions encountered at the building. During FSE1, it was discovered that an inactive in-floor heating system was present in the building interior, therefore the four sub-slab soil gas/indoor air sample pairs were changed to near-slab soil gas/outdoor locations. The planned outdoor air samples were moved to the building interior. A near-slab soil gas/outdoor air sample pair could not be completed along the western exterior wall of the building due to the presence of underground utilities (moved to the northwest corner). A total of four near-slab soil gas/outdoor air sample pairs and four indoor air samples were collected during FSE1. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.21.
7.4.8.3 Building 7265
Planned sampling at Building 7265 included a modified approach of two sub-slab soil gas/indoor air sample pairs and two outdoor air samples. Fewer samples were planned due to the building’s relatively small size. One interior location was biased to a floor drain in the garage. TCE is the only COI at the site.
Actual sampling at Building 7265 followed the planned approach. During FSE1, a total of two sub-slab soil gas/indoor air sample pairs and two outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.23.
7.4.8.4 Building 7309
Planned sampling at Building 7309 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One interior location was biased to a possible capped floor drain located in the northeastern portion of the building and a second location was biased to sub-floor hangar door tracks located in the southwestern portion of the building. TCE is the only COI at the site.
Actual sampling at Building 7309 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. After the
Air Force Civil Engineer Center 7-9 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
completion of field sampling during FSE2, it was discovered that one indoor air sample Summa canister (location 7309-AA002) did not fill sufficiently to allow for laboratory analysis. As such, there is no sample results for this location during FSE2. Completed sample locations are shown in Figure 11.25.
7.4.8.5 Building 8288
Planned sampling at Building 8288 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. Two interior locations are biased to floor drains located in the main hangar/shop area. TCE is the only COI at the site.
Actual sampling at Building 8288 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. One outdoor air sample was moved from the northwestern exterior wall to the southwestern corner due to unsafe accumulations of overhead ice. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.27.
7.4.8.6 Building 8326
Planned sampling at Building 8326 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One interior location is biased to a sub-floor vault located in the southeastern portion of the main hangar (associated with a PID detection observed during the building surveys). TCE is the only COI at the site.
Actual sampling at Building 8326 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.29.
7.4.9 Site ST037 South
7.4.9.1 Building 4228
Planned sampling at Building 4228 included a modified approach of four near-slab soil gas/outdoor air sample pairs and four indoor air samples. Aurora Military Housing indicated a vapor barrier was present beneath the slab floor of Building 4228. As such, sub-slab soil gas samples were not collected (in order to prevent damaging the vapor barrier). TCE is the only COI at the site.
Actual sampling at Building 4228 followed the planned approach. During FSE1, a total of four near-slab soil gas/outdoor air sample pairs and four indoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.31.

7.4.9.2 Building 4230
Planned sampling at Building 4230 included a modified approach of two near-slab soil gas/outdoor air sample pairs, two indoor air samples, and two crawlspace air samples (one beneath each trailer). Building 4230 consists of two connected skirted office trailers with a relatively small overall footprint. As such, a reduced number of samples was proposed. TCE is the only COI at the site.
Actual sampling at Building 4230 generally followed the planned approach. During FSE1, a total of two near-slab soil gas/outdoor air sample pairs, two indoor air samples, and two crawlspace air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. The two crawlspace air samples (locations 4230- AA005/AA006) were collected several days after the other ambient air samples at Building 4230 due to ice accumulation that prevented access to the crawlspaces. One additional outdoor air sample (location 4230-AA007) was collected during FSE2. Completed sample locations are shown in Figure 11.33.
7.4.9.3 Building 4314
Planned sampling at Building 4314 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. Two interior locations were planned for each section of the building. TCE is the only COI at the site.
Actual sampling at Building 4314 generally followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. At the end of the sampling event it was discovered that one pair of collocated sub-slab soil gas/indoor air sample Summa canisters (locations 4314-SG001/AA001) did not fill sufficiently to allow for analysis by the laboratory. As such, there are no analytical results for these samples during FSE1. The indoor air sample was collected during FSE2. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.35.
7.4.9.4 Buildings 5208A/5211A
Planned sampling at Building 5208A included a modified approach of four near-slab soil gas/outdoor air sample pairs and four indoor air samples. Building 5208A was identified for sampling by Aurora Military Housing as a vacant unit during FSE1 to avoid disturbing residents. Aurora Military Housing also indicated a vapor barrier was present beneath the slab floor of Building 5208A. As such, sub-slab soil gas samples were not collected (in order to prevent damaging the vapor barrier). The general sampling approach included one indoor air sample located in the garage, with the remaining indoor air samples distributed throughout the ground floor. TCE is the only COI at the site.
Actual sampling at Building 5208A followed a modified approach due to conditions encountered during FSE1. The planned exterior sample location along the garage door was moved to the backyard to avoid blocking the neighboring unit’s driveway. The presence of a backyard fence and gate limited the size of the DPT drill rig that could be used. The relatively lower-powered
Air Force Civil Engineer Center 7-11 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
skid-mounted DPT drill rig was not able to effectively penetrate the dense gravelly subsurface in the backyard, therefore only one near-slab soil gas/outdoor air sample pair was completed in this area. During FSE1, a total of three near-slab soil gas/outdoor air sample pairs and four indoor air samples were collected.
During FSE2, a different vacant unit (Building 5211A) was designated for sampling by Aurora Military Housing. This unit was located approximately 200 feet northeast of Building 5208A and consisted of the same construction and floor plan. Ambient air sampling conducted during FSE2 duplicated the sampling completed during FSE1 (e.g. similar locations relative to the building floor plan). Three of the four indoor air results collected during FSE2 were determined to be non-representative of actual conditions due to carpet cleaning that was conducted within 48 hours of sample collection. The indoor air sample located in the garage was not affected by the carpet cleaning and was retained. Completed sample locations are shown in Figure 11.37.
7.4.9.5 Building 5223
Planned sampling at Building 5223 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. Interior locations were biased to floor drains located throughout the building. TCE is the only COI at the site.
Actual sampling at Building 5223 generally followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.39.

Planned sampling at Building 7535 included a modified approach of three near-slab soil gas/outdoor air sample pairs, one sub-slab soil gas/indoor air sample pair in the basement mechanical room, one crawlspace air sample, and two indoor air samples. Sub-slab samples in the ground floor interior were not planned due to the building’s use as a dining facility. TCE is the only COI at the site.
Actual sampling at Building 7535 followed the planned approach. During FSE1, a total of three near-slab soil gas/outdoor air sample pairs, one sub-slab soil gas/indoor air sample pair (basement mechanical room), one crawlspace air sample, and two indoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.41.

Actual sampling at Building 8515 followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.43.
7.4.10.3 Building 8559
Planned sampling at Building 8559 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. One sub-slab soil gas/indoor air sample pair was biased to a sump pit located in a mechanical room in the northwestern portion of the building. TCE is the only COI at the site.
Actual sampling at Building 8559 followed a modified approach due to conditions encountered at the building. During FSE1, it was discovered that asbestos was present beneath the painted surface of the interior concrete slab floor, therefore the four sub-slab soil gas/indoor air sample pairs were changed to near-slab soil gas/outdoor air sample locations. The four planned outdoor air samples were moved to the building interior (one located in the mechanical room). During FSE1, a total of four near-slab soil gas/outdoor air sample pairs and four indoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.45.
7.4.10.4 Building 8574
Planned sampling at Building 8574 included a modified approach of four sub-slab soil gas/indoor air sample pairs, one near-slab/outdoor air sample pair, and four outdoor air samples. The near- slab soil gas/outdoor air sample pair was biased to the former UST location along the northwestern exterior wall. TCE is the only COI at the site.
Actual sampling at Building 8574 generally followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. The planned near-slab soil gas/outdoor air sample pair adjacent to the former UST location was not completed due to the present of underground utilities in the area. The relatively close proximity of the near-slab soil gas/indoor air sample pair inside the building in this area was deemed sufficient to characterize subsurface soil conditions. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.47.

7.4.11.1 Building 11550
Planned sampling at Building 11550 included a modified approach of four sub-slab soil gas/indoor air sample pairs in the basement; two indoor air samples on the first floor, and four outdoor air samples. COIs at the site include BTEX, GRO, and naphthalene.
Actual sampling at Building 11550 followed a modified approach due to conditions encountered at the building. During FSE1, it was discovered that an elevated floor (approximately 6 inches
Air Force Civil Engineer Center 7-13 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
high) overlying the concrete slab floor was present throughout most of the basement, therefore the four sub-slab soil gas/indoor air sample pairs were changed to near-slab soil gas/outdoor air sample locations. The four planned outdoor air samples were moved to the building basement. The two indoor air samples on the first floor were collected as planned. During FSE1, a total of four near-slab soil gas/outdoor air sample pairs, four indoor air samples (basement) and two indoor air samples (first floor) were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.49 (ground floor) and Figure 11.50 (basement).

7.4.12.1 Building 11551
Planned sampling at Building 11551 included the default approach of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples. Sample locations were generally biased to the western portion of the building, closest to the previously identified soil contamination area. One interior location was biased to an in-floor OWS located within the northwestern portion of the main hangar (associated with a PID detection observed during the building surveys). COIs at the site include BTEX, GRO, and naphthalene.
Actual sampling at Building 11551 generally followed the planned approach. During FSE1, a total of four sub-slab soil gas/indoor air sample pairs and four outdoor air samples were collected. The planned sub-slab soil gas/indoor air sample pair located in the center of the hangar was relocated to the east hangar wall to avoid potential conflicts with aircraft or events. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 11.52.
7.5 JBER-R SITES SAMPLING DESIGN AND RATIONALE

7.5.1.1 Building 726
Planned sampling at Building 726 included a modified approach of four sub-slab soil gas/indoor air sample pairs in the basement, three indoor air samples on the first floor, and four outdoor air samples.
One of the basement sample locations was biased to a sump pit located in the southeastern portion of the basement (associated with PID detections during the building surveys). One indoor sample

location was biased to the southeastern portion of the first floor (directly above the basement sump pit sample location). PCE is the only COI at the site.
Actual sampling at Building 726 followed a modified approach due to conditions encountered at the building. During FSE1, it was discovered that potential in-slab utilities in the basement could not be located, therefore the four sub-slab soil gas/indoor air sample pairs were changed to near- slab/outdoor air samples. The four outdoor air samples were changed to indoor air samples and moved into the basement. The first floor indoor air samples were collected as planned. During FSE1, a total of four near-slab soil gas/outdoor air sample pairs, four indoor air samples (basement), and two indoor air samples (first floor) were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 12.1 (ground floor) and Figure 12.2 (basement).
7.5.1.2 Building 728
Planned sampling at Building 728 included a modified approach of two near-slab soil gas/outdoor air sample pairs, two outdoor air samples (opposite the soil gas locations), one indoor air sample, and one crawlspace air sample. Building 728 is a skirted office trailer with a relatively small overall footprint. As such, a reduced number of samples was proposed. PCE is the only COI at the site.
Actual sampling at Building 728 followed the planned approach. During FSE1, a total of two near-slab soil gas/outdoor air sample pairs, two outdoor air samples, one indoor air sample, and one crawlspace air sample were collected.

7.5.1.3 Building 730
Planned sampling at Building 730 included a modified approach of two near-slab soil gas/outdoor air sample pairs, two outdoor air samples (opposite the near-slab soil gas locations), two sub- slab soil gas/indoor air sample pairs, one indoor air sample, and one crawlspace air sample. A crawlspace is present beneath the western portion of the building, therefore the near-slab soil gas/outdoor air sample pairs were planned adjacent to the western and northwestern exterior walls. The sub-slab soil gas/indoor air sample pairs were planned for the eastern portion of the building. PCE is the only COI at the site.
Actual sampling at Building 730 followed a modified approach due to conditions encountered at the building. During FSE1 it was discovered that potential in-slab utilities could not be located, therefore the two sub-slab soil gas/indoor air sample pairs were changed to near-slab/outdoor air samples. Three indoor air samples were collected (one located in the mechanical room in the southeastern portion of the building). The crawlspace sample was completed as planned. During FSE1, a total of four near-slab soil gas/outdoor air sample pairs, three indoor air samples, and one crawlspace air sample were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 12.6.

The near- slab soil gas/outdoor air sample pair was biased to the former UST location along the southwestern exterior wall. All interior sample locations also were generally biased to the southwestern portion of the building. COIs at the site include benzene and PCE.
Actual sampling at Building 740 followed a modified approach due to conditions encountered at the building. During FSE1, it was discovered that potential in-slab utilities could not be located, therefore the three planned sub-slab soil gas/indoor air sample pairs were changed to near- slab/outdoor air samples. The three outdoor air samples were changed to indoor air samples. The exterior sub-slab soil gas/outdoor air sample pair was collected as planned.
During FSE1, a total of four near-slab soil gas/outdoor air sample pairs and three indoor air samples were collected. During FSE2, ambient air sampling duplicated the sampling completed during FSE1. Completed sample locations are shown in Figure 12.10.
7.6 WASTE MANAGEMENT
The investigation derived waste (IDW) inventory associated with VI sampling included one 55- gallon drum of solid waste and two 55-gallon drums of waste water generated during FSE1. No IDW (other than sanitary trash) was generated during FSE2.
The solid waste drum included sub-slab soil gas floor coring cuttings and near-slab soil gas DPT drill cuttings. Solid waste from all sites on JBER-E and JBER-R were combined into the single drum. The waste water drums included decontamination water from near-slab soil gas DPT drilling and groundwater purge water generated during a separate groundwater sampling task. Used disposable waste items were managed and disposed as sanitary trash.
Air Force Civil Engineer Center 7-16 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
One waste characterization composite water sample was collected from the two drums of waste water and one composite solid sample was collected from the single drum of solid waste. Both waste characterization samples were submitted to TestAmerica, Inc. located in Sacramento, California for analysis of the full suite of parameters identified in the UFP-QAPP. Laboratory analytical results for the IDW waste characterization samples are included in Appendix D of this report; however, these results were not subject to data validation and are not discussed further in this report.
The shipment and disposal of the IDW drums was conducted by NRC Alaska. The drums were transported from the JBER Environmental Staging Facility to the NRC Viking facility in northern Anchorage on December 8, 2016. Based on the waste characterization results, the solid waste and waste water drums were disposed as non-regulated waste. Documentation associated with VI sampling IDW disposal is provided in Appendix D of this report.
7.7 DATA MANAGEMENT
Validated laboratory analytical results were managed using a Microsoft Access relational database. All electronic data were maintained in systems subject to regular backups to protect data in the case of equipment failure. Source data used for reporting were obtained from the project database to ensure consistency. If a revision of electronic data was identified, the required information was provided to the database manager for correction.
GIS data will comply with Spatial Data Standards for Facilities, Infrastructure, and Environment formatting requirements and the JBER Common Installation Picture, as applicable. GIS Metadata complied with Federal Geographic Data Committee Content Standards for Digital Geospatial Metadata for organization.
Hand-written field forms were collected during the field mobilizations and checked for completeness. Upon the completion of a field mobilization, field forms were electronically scanned to PDF format for archiving in the project files. Original field forms and logbooks were maintained in the project file. Digital photographs were downloaded daily to a laptop computer during the field mobilizations. Field form PDFs and digital photographs were retained in systems subject to regular backups.

8.0 DATA QUALITY SUMMARY
The evaluation of data quality and applicable requirements are defined in the UFP-QAPP. Two general categories of data were generated during the VI Study: screening data and definitive data.
Screening data are generated by rapid methods of analysis with less rigorous sample preparation, calibration, or QC requirements than are necessary to produce definitive data. Sample preparation steps may be restricted to simple procedures such as dilution with a solvent, instead of elaborate extraction/digestion and cleanup. Screening data may provide analyte identification and quantitation, although the quantitation may be relatively imprecise. Screening data may be considered of unknown quality without corresponding definitive confirmation data. Screening data for total VOCs in ambient air were generated during the building survey and field sampling events during the VI Study. This screening method has no corresponding definitive method, and results from this screening do not require confirmation. No screening data were generated by the subcontracted laboratory during the project.
Definitive data are generated using rigorous analytical methods. Definitive data are analyte specific, and both identification and quantitation are confirmed. Definitive analytical methods have standardized QC and documentation requirements and produce data for which analytical error (bias) can be determined. In order for data to be classified as definitive, the data must be validated after the results are reported in order to verify that the appropriate QC measures were taken and were in control. Also, the sample must be collected in a manner that is representative of current site conditions. Definitive data are not restricted in use unless quality problems identified in the validation process require data qualification. All subcontracted laboratory analyses were conducted by TestAmerica, Inc. of Sacramento, California. The following analytical methods were used by the subcontracted laboratory to generate definitive data:
• WS-MSA-0015: Determination of Low-Level Volatile Organics in Ambient/Indoor Whole Air Samples using GC/MS Scan Mod [Methods USEPA TO-14A and USEPA TO-15], Revision 1.1; 4/22/2013 (referred to as method TO-15 in this report). • WS-MSA-0016: Determination of Low-Level Volatile Organics in Ambient/Indoor Whole Air Samples using GC/MS-SIM [Method TO-15 SIM], Revision 1.3; 8/24/2015 (referred to as method TO-15 SIM in this report).
All of the soil gas and ambient air sample analytical results generated by the subcontracted laboratory during the VI Study are considered to be definitive data.
8.1 DATA VERIFICATION AND VALIDATION
All VI Study soil gas and ambient air sample results were verified and subject to validation per the requirements in the UFP-QAPP. Laboratory sample verification and validation were conducted on all samples within each Sample Delivery Group (SDG). In general, an SDG is comprised of a group of samples submitted to the laboratory in a single shipment or on a single chain-of-custody (COC) form. Larger SDGs were divided into smaller SDGs to facilities data verification, validation, and management.
Air Force Civil Engineer Center 8-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Data verification is a check that all specified activities involved in collecting and analyzing samples have been completed and documented and the necessary records (objective evidence) are available to proceed to data validation. HGL conducted data verification to confirm the subcontracted laboratory correctly logged received samples and that samples were scheduled for the correct analyses. HGL also conducted verification upon receipt of analytical results to confirm the required data deliverables were accurate and complete. Any errors or other discrepancies identified during data verification were corrected through coordination between HGL and the laboratory on an as-needed basis.
Data validation is the evaluation of conformance to stated requirements, including those in the contract, methods, SOPs, and the UFP-QAPP. Subcontracted data validation was conducted by Laboratory Data Consultants, Inc. of Carlsbad, California. Data validation was performed under Level III guidelines using the UFP-QAPP and the following documents (as applicable to each analytical method):
• U.S. DoD, Quality Systems Manual for Environmental Laboratories, Version 5.0, July 2013 (QSM). • USEPA, Contract Laboratory Program National Functional Guidelines for Superfund Organic Methods Data Review, June 2008.
The LDC data validation activities and results are documented in data validation reports included in Appendix E of this report. Appendix E is organized by laboratory SDG, and each SDG folder includes the data validation report (along with the complete laboratory data package).
The HGL Project Chemist conducted a review of each LDC data validation report as a QC check of validation results. The HGL data validation review activities included discussions of any adverse conditions identified during validation and provides a summary of any changes to the laboratory data qualifiers. The results of the HGL data validation reviews are documented in SDG-specific reports also included in Appendix E.
The HGL Project Chemist also completed an ADEC Laboratory Data Review Checklist for Air Samples for each SDG as required by the ADEC Quality Assurance Technical Memorandum, March 2017 (ADEC, 2017a). The ADEC checklists are included for each SDG in Appendix E.
8.2 DATA QUALITY INDICATORS
Measurement performance criteria usually are expressed in terms of the data quality indicators (DQI) PARCCS, which include the following:
• Precision; • Accuracy; • Representativeness; • Comparability; • Completeness; and • Sensitivity.
Air Force Civil Engineer Center 8-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Of the above parameters, precision, accuracy, completeness, and sensitivity can be quantitatively measured and assessed. The parameters of comparability and representativeness are primarily qualitative in nature. Table 8.1 provides a summary of planned, collected, analyzed, and analytical result usability for VI samples collected during both field mobilizations. Table 8.2 provides a summary of analytical result precision, accuracy, and representativeness evaluations. The results of the DQI evaluations are discussed in detail below.
8.2.1 Quantitative Data Quality Indicator Evaluation
Quantitative DQIs were measured and assessed by performing QC checks and evaluating the results against numerical acceptance criteria. Where available, the method- and matrix-specific measurement performance criteria presented in the QSM were used by the subcontracted laboratory to control quantitative DQIs. Where the QSM does not list QC criteria, the control limits for routine analyses generated by the laboratory were used. These QC limits are sufficient to ensure that the analytical methods were performed under acceptable conditions and that results can be used as reported for the intended purposes.
8.2.1.1 Precision
The targeted field duplicate sample frequency indicated in the UFP-QAPP was 1 per every 10 regular samples for ambient air and soil gas (calculated separately for JBER-E and JBER-R). One of the 20 planned field duplicate samples for ambient air at JBER-E was not collected during FSE1 due to Summa canister supply limitations at the end of the field mobilization. All other planned field duplicate samples were collected and analyzed as planned (see Table 8.1).
FSE1
During FSE1, the laboratory performed a LCS and LCSD in each analytical batch. The relative percent difference (RPD) between the LCS and corresponding LCSD result for each analyte was compared to the RPD limits presented in the UFP-QAPP. All LCS/LCSD pairs met the precision criteria, with the exception of the RPDs for benzyl chloride and 2-hexanone in the LCS/LCSD pair reported for one Method TO-15 batch. The detected 2-hexanone result in sample JBERVISG0022 was qualified “J” by the data validators; the concentration in the affected sample is below the limit of quantitation and below the project screening level. All other associated results are non-detections and did not require qualification.
FSE2
During FSE2, the laboratory performed an LCS and LCSD in each analytical batch. The RPD between the LCS and corresponding LCSD result for each analyte was compared to the RPD limits presented in the UFP-QAPP. Three TO-15 SIM LCS/LCSD ambient air sample pairs had RPD >25% for naphthalene. Detected naphthalene results in all 11 associated samples were qualified “J” by the data validators; the final qualifier on the naphthalene results for samples JBERVIAA0291, JBERVIAA0412, and JBERVIAA0419 was changed to “UJ” because the affected results are detections above the limit of quantitation (LOQ) that were subsequently qualified “U” due to method blank contamination.
Air Force Civil Engineer Center 8-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
8.2.1.2 Accuracy
FSE1
During FSE1, the laboratory performed an LCS and LCSD in each analytical batch. The percent recovery (%R) in each LCS and LCSD was compared to the %R limits presented in the UFP- QAPP. All LCSs and LCSDs met the accuracy criteria, with the exception of hexachlorobutadiene in the LCS pair reported for one TO-15 batch; the %R in the corresponding LCSD was in control. All associated results are non-detections and did not require qualification.
All data were analyzed in association with acceptable initial calibration results. In some cases, TO-15 continuing calibration verification (CCV) standards showed a percent difference (%D) from the corresponding initial calibration that exceeded the 30% criterion but were less than 40%. The method allows for up to two analytes to show a %D ≤40% in any CCV standard without requiring corrective action. Eleven 1,1,2-trichloro-1,2,2-trifluoroethane, one dichlorodifluoromethane result, and twenty-seven 1,2,4-trichlorobenzene results were associated with the CCV discrepancies. All affected results were non-detections and were qualified “UJ” by the validators.
FSE2
During FSE2, the laboratory performed an LCS and LCSD in each analytical batch. The %R in each LCS and LCSD was compared to the %R limits presented in the UFP-QAPP. All LCSs and LCSDs met the accuracy criteria.
Several samples analyzed by TO-15 SIM showed discrepancies for one or more internal standards associated with reported target analytes. In all cases, the laboratory performed reanalysis; however, in some cases, the internal standard results in the reanalysis were also not in control and the affected analytes were qualified “J” (detections) or “UJ” (non-detections) by the data validators. The affected results include the detected TCE results in samples JBERVIAA0431 and JBERVIAA0384; the detected benzene and toluene results in sample JBERVIAA0428; and the detected BTEX results and non-detected naphthalene result in sample JBERVIAA0413.
8.2.1.3 Completeness
Table 8.1 provides a summary the total number of samples planned (per the UFP-QAPP), collected and analyzed, and the number of analyzed samples considered usable for the purposes of the VI Study. Table 8.1 also provides completeness percentages for the following categories:
• Collection – Number of samples collected versus number of samples planned; • Analytical – Number of samples analyzed versus number of samples collected; and • Usability – Number of samples usable versus number of samples analyzed.
The Table 8.1 values are grouped by field sampling event, base, and matrix (ambient air and soil gas), and are discussed further below.
Air Force Civil Engineer Center 8-4 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
FSE1
During FSE1, a total of three ambient air samples and one soil gas sample were not collected or analyzed as planned (see Table 8.1).
One outdoor air sample at Building 8691 (and the associated field duplicate sample) was not collected due to Summa canister inventory limitations at the end of the field mobilization. Due to the relative greater importance of indoor air samples (risk assessment) versus outdoor air samples (VI pathway evaluation), the field team eliminated one planned outdoor air sample location along the southern side of the building (8691-AA008) and moved the remaining sample location (8691-AA007) to the center of the southern exterior wall.
One collocated pair of outdoor air and near-slab soil gas samples at Building 5208A were not collected due to shallow borehole refusal by the skid-mounted DPT drill rig. A larger, tracked DPT drill rig could not be used for these planned sample locations (5208A-AA008 and 5208A- SG004) due to access limitations presented by a backyard fence.
One collocated pair of ambient air and sub-slab soil gas samples at Building 4314 were collected at locations 4314-AA001 and 4314-SG001, but the Summa canisters were found to contain insufficient volume to allow for sample analysis. As a result, these samples could not be analyzed.
FSE2
During FSE2, three ambient air samples were not collected or analyzed as planned (see Table 8.1). Two of the ambient air samples not collected were because of samples collected at the same locations during FSE1 (including Building 5211A outdoor air and Building 8691 outdoor air). Building 5211A was sampled during FSE2 because of the unavailability of neighboring Building 5208A.
One indoor air sample at Building 7309 was collected at location 7309-AA002, but the Summa canister was found to contain insufficient volume to allow for sample analysis. As a result, this sample could not be analyzed.
One additional unplanned outdoor air sample at Building 4230 was collected due to the inability of the field team to access the office trailer crawlspaces (access hatches frozen). The extra outdoor air sample was located directly adjacent to the crawlspace access hatch (sample 4230- AA006). Both crawlspace ambient air samples were collected later in the field mobilization, but the extra outdoor air sample was retained and analyzed.
8.2.1.4 Sensitivity
The following sections discuss the overall sensitivity of indoor air and soil gas laboratory analytical results during the VI study. The sensitivity evaluation is based on the occurrence of non-detected results with reported concentrations greater than project screening levels. Laboratory analytical results for outdoor air and crawlspace air samples do not have associated
Air Force Civil Engineer Center 8-5 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
project screening levels and are not included in the discussions below. Also, field blank samples were not collected during the VI study.
FSE1
During FSE1, indoor air laboratory analytical results were generated for a total of 332 individual analyses (including field duplicate samples) for the site-specific COIs. Of these, a total of 118 results were non-detects (35.5%) and a total of 5 of the non-detects (4.2%) were reported at concentrations greater than their lowest respective project screening levels. All five of these non-detects were for GRO.
For soil gas, laboratory analytical results were generated for a total of 6,642 individual analyses for the full reporting list of VOCs and GRO. Of these, a total of 4,578 results were non-detects (68.9%) and a total of 515 of the non-detects (11.2%) were reported at concentrations greater than their lowest respective project screening levels.
FSE2
During FSE2, indoor air laboratory analytical results were generated for a total of 340 individual analyses (including field duplicate samples) for the site-specific COIs. Of these, a total of 54 results were non-detects (15.9%) and a total of 1 non-detect (1.9%) was reported at a concentration greater than its lowest respective project screening level. Similar to FSE1, this non-detect was for GRO.
8.2.2 Qualitative Data Quality Indicator Evaluation
The following sections summarize the DQI evaluations for qualitative criteria including comparability and representativeness.
8.2.2.1 Comparability
VI study laboratory analytical results for indoor air are compared to their applicable project screening levels and are evaluated in the risk assessment. Although soil gas samples also are compared to project screening levels, these results are only used in the VI pathway evaluations in Section 10 of this report. As noted previously, results for outdoor air and crawlspace air samples do not have associated project screening levels and are only used in the VI pathway evaluations.
8.2.2.2 Representativeness
The following sections discuss the representativeness of VI study laboratory analytical results based on information from the laboratory data packages and observed field conditions during sampling.
Air Force Civil Engineer Center 8-6 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
FSE1
The laboratory analyzed a method blank in each batch and the method blank results were used to determine whether detected results in the associated samples were representative of site conditions or potential artifacts of the analytical process. Multiple TO-15 batches showed contamination with toluene at concentrations below one-half the LOQ; all associated toluene results were either detections greater than the qualification threshold calculated from the associated blank result or were non-detections. One TO-15 batch showed toluene contamination greater than one-half the LOQ and also showed contamination with o-xylene and m,p-xylenes below one-half the LOQ. Four toluene results, three m,p-xylenes results, and three o-xylene results were qualified “U” by validator. All affected results were below the associated screening values.
Three TO-15 batches showed contamination with acetone at concentrations below one-half of the LOQ. Nine acetone results were qualified “U” by the validator. All affected results were below the acetone screening value.
Three TO-15-SIM batches showed contamination with naphthalene at concentrations below one- half of the LOQ. Eight naphthalene results were qualified “U” by the validator. Four of the qualified results were greater than the naphthalene screening value; the affected results included those reported for samples JBERVIAA0008, JBERVIAA0019 (and its field duplicate JBERVIAA9006), and JBERVIAA0021.
In addition to analyzing method blanks, the laboratory analyzed a Summa canister blank in association with each batch of Summa canisters cleaned. These Summa canister blanks were occasionally found to be contaminated with low levels of VOCs when analyzed by method TO- 15; the validators applied “U” qualifiers to detected associated results that were below the calculated qualification thresholds. The qualified results included common laboratory contaminants acetone (10 results) and methylene chloride (21 results), as well as carbon disulfide (2 results) and 2-hexanone (three results). All affected results were below the associated screening values.
The case narrative for SDG 320-22013-1 (Site DA089 Building 728) indicated that the GRO results reported for samples JBERVISG0101 and JBERVISG0102 (and its field duplicate JBERVISG9010) are due to the presence of discrete peaks of PCE rather than to a petroleum pattern. The PCE results were also reported independent of the GRO results for each of the affected samples. HGL contacted the laboratory and was informed that there was no way to subtract out the reported PCE concentration and the GRO results were reported “as is” in accordance with laboratory procedures. It is possible that the GRO results in the affected samples are false positives and this represents a potential usability issue for the reported results.
FSE2
The laboratory analyzed a method blank in each batch and the method blank results were used to determine whether detected results in the associated samples were representative of site conditions or potential artifacts of the analytical process. Four TO-15 SIM batches showed
Air Force Civil Engineer Center 8-7 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
contamination with naphthalene at concentrations below one-half of the LOQ. Ten naphthalene results were qualified “U” by the validator. Four of the qualified results were greater than the naphthalene screening value; the affected results included those reported for samples JBERVIAA0491, JBERVIAA0412, JBERVIAA0419, and JBERVIAA0420.
One TO-15 SIM batch showed benzene and toluene contamination less than one-half the LOQ and another TO-15 SIM batch showed contamination with TCE below one-half the LOQ; all associated results were either detections greater than the qualification threshold calculated from the associated blank result or were non-detections.
In addition to analyzing method blanks, the laboratory analyzed a Summa canister blank in association with each batch of Summa canisters cleaned. These Summa canister blanks were occasionally found to be contaminated with low levels of VOCs when analyzed by Method TO- 15 SIM. The only affected result was a TCE concentration below the screening value reported in sample JBERVIAA0345. This result was qualified “U” by the validators.
Three indoor air samples at Building 5211A are not considered to be representative of ambient conditions relative to potential VI due to carpet cleaning activities conducted within 48 hours of the start of sample collection. Numerous VOCs, including TCE (the only site-specific COI), where detected in the three indoor air samples located in the main open living space of the residence. The remaining indoor air sample was located in the garage and was non-detect for TCE.
8.3 DATA USABILITY
Nearly all of the ambient air and soil gas sample results generated during the two VI Study field sampling events are considered usable per the project DQOs. Exceptions to data usability are discussed below.
Per the representativeness evaluation discussed above, elevated soil gas sample results for GRO in the two soil gas samples at JBER-R Building 728 (Site DA089) are due to the presence of elevated PCE concentrations rather than to petroleum contamination. It is possible that the GRO results in the affected samples are false positives and, therefore, these results are not considered usable for the VI pathway evaluation at this BOI. These GRO results are not included in the data summary tables or figures in this report.
Also per the representativeness evaluation discussed above, elevated TCE results in three of four indoor air samples in JBER-E Building 5211A (Site ST037) are potentially impacted by ambient VOCs (including TCE) associated with carpet cleaning activities conducted within 48 hours of the start of sample collection. The indoor air sample located in the garage (5211A-AA005) is located in a separate air space (no carpet, separated by a door) from the main living area and was non-detect for TCE. It is not possible to definitively associate the TCE results in the affected samples with VI, and therefore these results are not considered usable for the risk assessment or VI pathway evaluation at this BOI. The three indoor air TCE results from the main living area are not included in the data summary tables or figures in this report.
Air Force Civil Engineer Center 8-8 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Based on the results of the DQI evaluations, and excluding the unusable samples described above, all remaining VI ambient air and soil gas laboratory analytical results are considered valid and usable for their intended use per the UFP-QAPP and the associated DQOs.

9.0 VI SAMPLE RESULTS SCREENING
The preliminary screening of VI study field sampling results for indoor air and soil gas included comparisons to the JBER Response Action Levels and ADEC Notification Levels provided in Attachment A of the UFP-QAPP. Indoor air and soil gas sample results also were compared to the project screening levels (PSL) identified in the UFP-QAPP. The results of these screenings are discussed below.
9.1 PRELIMINARY SCREENING (JBER RESPONSE/ADEC NOTIFICATION)
Initially, indoor air sample results were compared to the action levels presented in Attachment A of the UFP-QAPP in order to identify the potential need for a response action by JBER at one or more BOIs. This comparison was conducted immediately after indoor air sample results were received from the laboratory and data validation was completed for each field sampling event. The potential indoor air response actions included Accelerated and Urgent (JBER), and ADEC Notification Levels (ADEC, 2017a). The response action levels were provided by the JBER ERP and include cancer and non-cancer values. If an indoor air result exceeded a respective action level, the JBER Bioenvironmental Engineering Office (673 AMDS/SGPB) implemented their response action plan for the applicable BOI. None of indoor air results exceeded a respective notification level for ADEC.
A preliminary screening for soil gas results, using the ADEC Notification Levels provided in the UFP-QAPP, was not conducted because screening of soil gas results (see Section 9.2 below) used PSLs that were several orders of magnitude lower than the ADEC Notification Levels (and therefore were more conservative).
For FSE1, none of the indoor air sample results exceeded preliminary screening levels. For FSE2, one PCE result (570 g/m3 [micrograms per cubic meter]) at sample location 726-AA008 in the basement of Building 726 exceeded both JBER response action levels. This indoor air sample is located in the northμ end of the basement, which is not a regularly occupied space. Building 726 is a commercial/industrial dry cleaning facility. The JBER ERP coordinated with JBER Bio-Environmental regarding the indoor air results. VI study sample results for Building 726 are shown in Figure 12.1.
9.2 PROJECT SCREENING LEVELS
Indoor air and soil gas results generated during both field sampling events were compared to their applicable PSLs to identify potentially elevated concentrations. Indoor air results were compared to the PSLs identified in Table 9.4. The project screening levels include residential and commercial/industrial ADEC Indoor Air Target Levels based on a cancer risk of 1x10-5 or a HQ of 1, and USEPA RSL for ambient air based on a cancer risk of 1x10-6 or a HQ of 0.1. The potential risk to human health associated with indoor air results at each BOI was quantified by conducting a risk assessment consistent with the requirements of USEPA Risk Assessment Guidance for Superfund Volume 1: Human Health Evaluation Manual (Part F, Supplemental Guidance for Inhalation Risk Assessment), Final, OSWER 9285.7-82 (USEPA, 2009). The risk assessment methodology and results are presented in Section 10 of this report.
Air Force Civil Engineer Center 9-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Sub-slab and near-slab soil gas sampling results were compared to the applicable screening levels provided in Table 9.5. The project screening levels include ADEC Shallow or Sub-slab Target Levels and values calculated using the USEPA VISL Calculator (modified to include June 2017 RSL toxicity values). The calculated VISLs are based on a cancer risk of 1x10-6 and non-cancer risk THQ of 1.
The presence of an indoor air or soil gas result that exceeded one or more PSLs does not, on its own, represent a risk to building occupants or suggest further characterization is warranted. The project screening was conducted to support the site- and BOI-specific discussions of sample results, VI pathway evaluations, and conceptual site models (CSM) and is not intended to replace the risk assessment described in Section 10 (indoor air only). Results for outdoor air and crawlspace air are intended for use in the VI pathway evaluations and are not included in the project screening.
9.2.1 Indoor Air (ADEC Target Levels/USEPA RSLs)
The results of the project screening for JBER-E indoor air are presented in Table 9.6. Screening results are presented for site-specific COIs for both sampling events with respect to the PSLs appropriate for the specific building use.
Based on comparison to the lowest applicable indoor air PSL, the following JBER-E site/buildings had at least one COI exceeding an indoor air PSL:
• Site FT023 (Building 17534) - benzene. • Site ST032 (Building 13272) - benzene, ethylbenzene, and naphthalene; GRO (C4-C12) and total xylenes. • Site ST037 (Building 4230, 6211, 7309, 8326) - TCE. • Site ST048 (Building 11550) - benzene and naphthalene, GRO. • Site ST068 (Building 11551) - GRO. • Site TU091 (Building 8574) - TCE.
The results of the project screening for JBER-R indoor air are presented in Table 9.7. Screening results are presented for site-specific COIs for both sampling events with respect to the PSLs appropriate for the specific building use.
Based on comparison to the applicable indoor air PSL, the following JBER-R sites/buildings had at least one COI exceeding an indoor air PSL:
• Site DA089 (Buildings 726, 730) - PCE. • Site TU064 (Building 740) - benzene.
In general, COI concentrations (and the resulting number of indoor air PSL exceedances) at JBER-E and JBER-R sites were higher during FSE2. This trend is attributed to the winter heating season and associated “stack effect” that may result in increased potential for VI.
Air Force Civil Engineer Center 9-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
9.2.2 Soil Gas (ADEC Target Levels/USEPA VISLs)
The results of the project screening for JBER-E soil gas are presented in Table 9.8. Screening results are presented for site-specific COIs with respect to the soil gas PSLs appropriate for the specific building use. Due to the large number of analytes included in the soil gas analyses, the summary table only presents detected results.
Based on comparison to the lowest applicable soil gas PSL, the following JBER-E site/buildings had at least one chemical detected in soil gas exceeding a soil gas PSL:
• Site CG704 (Building 8691) - 1,2,4-trimethylbenzene. • Site SD029 (Building 16716) - ethylbenzene and total xylenes. • Site SS022 (Building 12755) - carbon tetrachloride and chloroform. • Site ST032 (Building 13272) – PCE. • Site ST036 (Building 27369) - 1,1,2-trichloroethane, benzene, and naphthalene. • Site ST037 (multiple buildings) - 1,1,2,2-tetrachloroethane, 1,2,4-trimethylbenzene, carbon tetrachloride, chloroform, dichlorodifluoromethane, ethylbenzene, TCE, and total xylenes. • Site ST068 (Building 11551) - ethylbenzene, naphthalene, TCE, and total xylenes. • Site TU091 (Building 8574) - chloroform, ethylbenzene, and TCE.
The results of the project screening for JBER-R soil gas are presented in Table 9.9. Screening results are presented for site-specific COIs for FSE1 with respect to the soil gas PSLs appropriate for the specific building use. Due to the large number of analytes included in the soil gas analyses, the summary table only presents detected results.
Based on comparison to the lowest applicable soil gas PSL, Site DA089 Buildings 728 and 730 were the only locations with soil gas results exceeding PSLs. (chloroform, ethylbenzene, PCE, and TCE).
The PSL screening results summarized above and shown in the applicable tables are discussed further in the site- and BOI-specific evaluations in Section 11 (JBER-E) and Section 12 (JBER- R) of this report.

10.0 VI RISK ASSESSMENT
To estimate potential risk to human health associated with exposure to indoor air at each BOI, a risk assessment was conducted in accordance with the UFP-QAPP (USAF, 2016) and the requirements of USEPA Risk Assessment Guidance for Superfund Volume 1: Human Health Evaluation Manual (Part F, Supplemental Guidance for Inhalation Risk Assessment), Final, OSWER 9285.7-82 (USEPA, 2009). This section describes the risk assessment approach and results. Tables supporting the risk assessment are presented in Appendix F of this report, which is organized by BOI. The supporting tables are numbered within Appendix F per USEPA risk assessment guidance, and are not numbered sequentially with respect to the remainder of this report. Where referenced, the tables supporting the risk assessment are noted as being included in Appendix F.
10.1 EXPOSURE SETTING
The VI study field investigation sampled indoor air at 30 BOIs. With the exception of the Dallas Housing residential units (Buildings 5208A/5211A), all of the remaining BOIs at JBER-E and JBER-R are classified as commercial/industrial use and include office facilities, maintenance facilities, aircraft hangars, a DRMO warehouse, a physical training facility, a community center, a dining hall, and a dry cleaner.
At most of the BOIs, contaminated groundwater is the potential source for VI. Areas of soil contamination are the potential source for VI at Buildings 8574 (Site TU091), 740 (Site TU064), and 27369 (Site ST032). Site-specific COIs are provided in Table 1.1 of this report. Because each BOI represents an individual exposure area, a separate risk assessment was performed for each BOI.
10.2 POTENTIAL RECEPTORS AND EXPOSURE ROUTES
Under current conditions, the primary receptor is an individual who works in the industrial/commercial facilities. The resident is the primary receptor at residential use Buildings 5208A and 5211A.
Indoor workers and residents could be exposed to groundwater and/or soil contamination via the inhalation of impacted indoor air that has entered structures via the VI exposure pathway. Additional potential exposure pathways, such as incidental ingestion of soil contaminants, ingestion of groundwater as a drinking water source, and dermal contact, were not evaluated in this risk assessment.
In summary, the following receptors and exposure routes were identified for quantitative analysis:
• Current/future indoor worker (adult): Exposure to indoor air associated with vapor intrusion from soil and/or groundwater contaminants.
Air Force Civil Engineer Center 10-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
• Current/future resident (child, adult, and age-adjusted): Exposure to indoor air associated with VI from soil and/or groundwater contaminants. The current/future resident scenario applies only to Buildings 5208A and 5211A.
The potential receptors and exposure pathways are summarized in Table 1.1 of Appendix F.
10.3 DATA USED IN THE RISK ASSESSMENT
To best reflect the potential exposure routes, the dataset used in the risk assessment for each BOI included indoor air samples collected during FSE1 and FSE2. Soil gas, crawlspace air, and outdoor air results were intended to support the VI pathway evaluations (i.e., is the VI pathway complete, potentially complete, or incomplete?) and therefore were not used in the risk assessment. For most BOIs, multiple indoor air samples were collected during each sampling event. In these cases, the maximum detected concentration over both FSE1 and FSE2 for each site-specific COI was used to estimate VI risk, which is conservative as it assumes all receptors in the building would be exposed at the location of the maximum detected concentration for the duration of the exposure period.
The migration of subsurface contaminants into aboveground structures via VI is a complex process with many variables, including temporal variations. These temporal variations include changes in ambient temperature observed throughout the year. The vapor intrusion migration pathway is generally most significant during the winter months, when ventilation is reduced, structures are heated, and the temperature of the soil beneath a structure relative to surrounding soil is increased per the Fluctuation of Indoor Radon and VOC Concentrations Due to Seasonal Variations, EPA/600/R-12/673 (USEPA, 2012). To evaluate fluctuations in indoor air concentrations and evaluate effects based on seasonality, and estimate the associated risk to human health, the indoor air results collected during the two field sampling events (early fall and winter) were evaluated. However, as noted above, the maximum detected indoor air concentration for each COI was used to quantitatively estimate risk.
10.4 EXPOSURE QUANTIFICATION
Exposure was quantified in accordance with USEPA guidance. Standard default exposure assumptions were used for the site receptors. All exposure assumptions (exposure duration, exposure frequency, etc.) are summarized in Table 4.1 of Appendix F.
10.5 TOXICITY ASSESSMENT
Toxicity values were obtained in accordance with OSWER Directive 9285.7-53 (USEPA, 2003). Toxicity values are summarized in Table 5.2 and Table 6.2 of Appendix F.
TCE was identified as a COI at multiple BOIs evaluated in the risk assessment. TCE is considered to act via a mutagenic mode of action (MMOA) with children having greater susceptibility to carcinogenic effects as compared to adults (https://archive.epa.gov/osa/mmoaframework/web/html/index.html). To account for the MMOA, an age-dependent adjustment factor (ADAF) was applied to the inhalation unit risk
Air Force Civil Engineer Center 10-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
(IUR) (USEPA, 2005). Per USEPA guidance (USEPA, 2006), the default ADAFs used to adjust the toxicity values include:
• 0 to 2-year olds (ADAF=10); • 3 for 2 to 6-year olds (ADAF=3); • 3 for 6 to 16-year olds (ADAF=3); and • 1 for 16 to 26-year olds (ADAF=1).
One of the studies used to derive the TCE toxicity values indicated that an acute exposure to TCE can have adverse developmental effects in fetuses (USEPA, 2011). To assess the potential for an acute hazard, the indoor air TCE concentrations were compared to the USEPA Region 9 indoor air response action screening values of 7 µg/m3 (based on a 10-hour work day) and 8 µg/m3 (based on an 8-hour work day) for the indoor worker, and 2 µg/m3 for the resident (USEPA, 2014). The acute evaluation is further described in Section 10.6 below.
Indoor air samples from buildings associated with petroleum contamination were analyzed for GRO in addition to the applicable VOC COIs. GRO was detected in samples from Buildings 11550, 11551, and 13272. GRO is a mixture of petroleum compounds with varying degrees of toxicity. Procedures for Calculating Cumulative Risk (ADEC, 2016) states that certain indicator compounds, such as benzene, toluene, ethylbenzene, xylenes, and naphthalene, should be used to assess potential cumulative risks associated with exposure to petroleum compounds. In accordance with this guidance, potential risks associated with the GRO detections in indoor air were not included in the calculation of cumulative risk. The uncertainties associated with this approach are discussed for the affected buildings in Section 11.11 (Building 11550), Section 11.12 (Building 11551), and Section 11.6 (Building 13272).
10.6 RISK CHARACTERIZATION
Using the equations provided by USEPA (USEPA, 2009a), an adjusted air concentration for each COI was calculated for each receptor scenario. The adjusted air concentration (aka receptor intake concentration) is the exposure point concentration (i.e., the maximum detected concentration in indoor air samples) adjusted to account for the receptor’s exposure time and averaging time.
The adjusted air concentrations were then combined with reference concentrations and inhalation unit risks to calculate the non-cancer hazards and cancer risks via the inhalation exposure pathway. For a given receptor, cancer risks were calculated for each COI using the following equation:
ILCR (inhalation) = Ca x IUR
Where: Ca = concentration in air adjusted for exposure time (mg/m3) ILCR = Incremental Lifetime Cancer Risk IUR = inhalation unit risk (mg/m3)-1
Air Force Civil Engineer Center 10-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
The non-cancer HQ for each COI was calculated using the following equation:
HQ (inhalation) = Ca / RfC
Where: Ca = air concentration adjusted for exposure time (mg/m3) RfC = reference concentration (mg/m3)
The cancer risks for each COI were summed to estimate the cumulative cancer risk via the inhalation pathway for indoor air. Per OSWER Directive 9355.0-30, “[w]here the cumulative carcinogenic site risk to an individual based on reasonable maximum exposure for both current and future land use is less than 1 x 10-4 and the non-carcinogenic hazard quotient is less than 1, action generally is not warranted unless there are adverse environmental impacts.” (USEPA, 1991). If the cumulative cancer risk exceeds 1 x 10-4, then action is generally warranted to reduce exposure. The 1 x 10-4 to 1 x 10-6 cancer risk range is consistent with the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), where acceptable levels of incremental lifetime cancer risk can be allowed to remain in situ (based on the degree of confidence or uncertainty underpinning the quantitative point estimates) within this range. The state of Alaska uses a cumulative cancer risk of 1 x 10-5 as the threshold for evaluating further action.
The estimated non-cancer HQs for each COI were summed and the total Hazard Index (HI) was compared to a threshold of 1. A HI less than or equal to 1 indicates that adverse effects are unlikely for exposure to the COIs. A HI greater than 1 indicates that adverse health effects may occur. The total HI and cumulative cancer risks calculated for indoor air at each BOI are presented in Table 10.1 of this report.
As described in Section 10.5 above, an evaluation of a short-term exposure scenario for TCE in indoor air was performed in addition to evaluating a chronic exposure scenario. For this evaluation, maximum TCE detections in indoor air were compared to the EPA Accelerated Response Action Levels for an industrial/commercial worker (8 micrograms per cubic meter [µg/m3] for 8-hour work day, 7 µg/m3 for 10-hour work day) and for a resident (2 µg/m3), as shown in Table 10.2. Estimated human health risks associated with indoor air for BOIs at JBER- E are discussed in Section 11 and BOIs at JBER-R are discussed in Section 12.

11.0 JBER-E FINDINGS AND RESULTS
This section discusses the findings and results of the VI study at JBER-E sites and BOIs including sample results, indoor air risk evaluation, VI pathway evaluation, and revised CSM.
Frequencies of detection (FOD) for JBER-E COIs in indoor air and outdoor air samples are presented in Table 11.1. The table includes separate totals for both field sampling events. The indoor air FODs remained the same or increased during FSE2 for all COIs (excluding 1,1- dichloroethene, which was not detected in either event). The outdoor air FODs varied widely, with some remaining the same, increasing, or decreasing. The total FODs for FSE2 were higher for indoor air and outdoor air. Average sample concentrations for detected site-specific COIs in indoor air show a general increase from FSE1 to FSE2 (see Table 11.2). The most significant increases are associated with GRO and BTEX.
The VI pathway analysis used the following criteria to screen buildings with respect to complete, potentially complete, or incomplete VI pathways:
• Complete VI pathway: COIs present in indoor air and soil gas and soil gas concentrations are greater than indoor air concentrations; no apparent impacts from outdoor air or non-VI interior sources of VOCs (e.g., gasoline in vehicle bays or solvent use, etc.). • Potentially complete VI pathway: COIs present in indoor air and soil gas and soil gas concentrations are greater than indoor air concentrations; however, potential impacts to indoor air from outdoor air or non-VI interior sources cannot be ruled out and prevent a more definitive identification of the pathway as “complete.” • Incomplete VI pathway: COIs are not detected or only very infrequently detected (e.g., 1 of 4 samples) in soil gas and/or COIs are not detected in indoor air.
The following sections summarize ambient air and soil gas results for each site and BOI included in the JBER-E field data collection program. Ambient air results are shown for site-specific COIs for each field sampling event. Due to the relatively long list of analytes included in the soil gas analyses, the results shown below are limited to site-specific COIs to support the VI pathway evaluation.
11.1 SITE CG704
11.1.1 Building 8691
The Building 8691 Propulsion Flight facility is an operational commercial/industrial use jet engine maintenance facility that includes offices on the first and second floors in the southern portion and a high-bay shop in the northern portion. The building is occupied by approximately 20 people on a normal workweek and day shift basis (Monday - Friday, 10 hours per day). Observed floor penetrations are limited to floor drains. Ambient air PID detections in the shop appeared to be directly associated with engine repair activities. Building 8691 is located partially
Air Force Civil Engineer Center 11-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
within the groundwater contamination plume buffer zone and TCE is the only COI. The depth to groundwater is approximately 30 feet bgs.
11.1.1.1 VI Sampling Results
Ambient air and soil gas results for Building 8691 are summarized in Table 11.3 and shown in Figure 11.1. Complete analytical results are provided in Table 11.4 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
TCE was detected in one indoor air sample during FSE1, and in all four indoor air samples during FSE2 at low concentrations (estimated, J-qualified) below the industrial indoor air PSL. TCE was not detected in soil gas during FSE1. One non-COI (1,2,4-trimethylbenzene) was detected in soil gas at a concentration greater than its respective PSLs.
11.1.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air result, the total HI was below 1 at 0.005 and the cumulative cancer risk was below 1x10-4 at 1x10-8 (see Table 10.1) for an indoor worker at Building 8691.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.044 J µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10- hour work day (7 µg/m3).
11.1.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 8691 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 8691 is located within the buffer zone of a VOC groundwater contamination plume with the depth to groundwater approximately 30 feet bgs. The building is relatively airtight during normal operations, although office windows and engine shop doors may be left open during warmer weather. Floor drains were the only floor penetrations identified. The use of parts-cleaning solvents was noted and VOCs were detected in ambient air in the engine shop near active maintenance activities. Neutral sub-slab air pressure gradients (i.e., no measurable pressure difference) were indicated during soil gas sampling (see Table 7.1).
TCE was detected in indoor and outdoor air samples at relatively low estimated concentrations during FSE1 and FSE2, which may indicate the presence of a general ambient air source in the area. There is no spatial bias apparent in the locations of the ambient air TCE detections. TCE was not detected in soil gas during FSE1.

Based on the above lines of evidence, the VI pathway is incomplete at Building 8691.

11.2.1 Building 18220
Building 18220 is an operational commercial/industrial use administrative facility with a basement, ground floor, and partial second floor. The building is occupied by approximately 100 people on a normal workweek and day shift basis (Monday - Friday, 10 hours per day). There were no ambient air PID detections in or around the building. The building is located partially within the groundwater contamination plume boundary. Site DP098 COIs include: 1,1- DCE; cis-1,2-DCE; PCE; TCE; and vinyl chloride. Due to security restrictions, not all areas within the building were accessed during field sampling activities. No photographs of the building interior or exterior were allowed. Groundwater is present at approximately 15 feet bgs or less in the vicinity of the building.
11.2.1.1 VI Sampling Results
Ambient air and soil gas results for Building 18220 are summarized in Table 11.5 and shown in Figure 11.3 (ground floor) and Figure 11.4 (basement). Complete analytical results are provided in Table 11.6 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
PCE and TCE were the only COIs detected in indoor air samples during FSE1 and FSE2, and none of the results exceeded industrial indoor air PSLs. PCE and vinyl chloride were the only COIs detected in outdoor air during FSE1 and FSE2. No soil gas results were greater than their industrial soil gas PSLs.
11.2.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air result, the total HI was below 1 at 0.02 and the cumulative cancer risk was below 1x10-4 at 7x10-8 (see Table 10.1) for an indoor worker at Building 18220.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.072 J µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10- hour work day (7 µg/m3).
11.2.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 18220 included the following lines of evidence:
Air Force Civil Engineer Center 11-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
The northeastern portion of Building 18220 is located within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 15 feet bgs or less. The building is relatively airtight during normal operations, although office windows may be left open during warmer weather. Access to the building was limited to the VI sampling locations due to security restrictions, therefore, a thorough survey was not conducted to identify floor penetrations. No floor penetrations were noted during VI sampling. No non-VI ambient air COI contaminant sources were identified.
One downward (i.e., positively pressurized building interior) sub-slab air pressure gradient (- 0.006 inches of mercury [in-Hg]) was identified at the start of soil gas sampling at location 18220-SG003 in a utility closet in the northern portion of the basement. Neutral sub-slab air pressure gradients (i.e., no measurable pressure difference) were indicated at the remaining sub- slab locations during soil gas sampling (see Table 7.1).
PCE was detected in indoor and outdoor air during FSE1 and FSE2. Concentrations of PCE in indoor air were consistently higher than those in outdoor air. TCE was detected in indoor air, primarily during FSE2, but was not detected in outdoor air during either sampling event. The ratios between the maximum detected concentrations in soil gas and indoor air for PCE:TCE include the following:
• Soil gas = 1.5:1; • Indoor air (FSE1) = 2.3:1; and • Indoor air (FSE2) = 9:1.
Although the ratio for FSE2 is inconsistent with the others, the PCE concentration is consistently higher than TCE in each case.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 18220. The source for PCE in outdoor air represents an uncertainty in the VI pathway evaluation.
11.2.1.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 18220 has been revised to indicate a potentially complete VI pathway for PCE and TCE. The revised CSM is shown in Figure 11.5.
11.2.2 Building 18224
Building 18224 is an operational commercial/industrial use facility with a ground floor and a small basement mechanical room located in the southwestern corner. The building includes a
Air Force Civil Engineer Center 11-4 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
garage, is used mostly for storage, and is only intermittently occupied. Chemicals stored in the building in flammable cabinets include oil, gasoline, insect repellant, putty, caulk, paint, and primer. The building is located adjacent to and north of Building 18220, and is located partially within the groundwater contamination plume boundary. Site DP098 COIs include: 1,1-DCE; cis-1,2-DCE; PCE; TCE; and vinyl chloride. Groundwater is present at approximately 15 feet bgs or less in the vicinity of the building.
11.2.2.1 VI Sampling Results
Ambient air and soil gas results for Building 18224 are summarized in Table 11.7 and shown in Figure 11.6. Complete analytical results are provided in Table 11.8 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
TCE was the only COI detected in indoor air samples during FSE1. PCE, TCE, and vinyl chloride were detected in indoor air during FSE2. None of the indoor air results exceeded industrial indoor air PSLs. TCE was the only COI detected in outdoor air samples during FSE1. PCE, TCE, and vinyl chloride were detected in outdoor air during FSE2.
PCE and TCE were detected in soil gas during FSE1, and three TCE concentrations exceeded the industrial soil gas PSL. Other than TCE, no soil gas results were greater than their industrial soil gas PSLs.
11.2.2.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.02 and the cumulative cancer risk was below 1x10-4 at 7x10-8 (see Table 10.1) for an indoor worker at Building 18224.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.21 µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10-hour work day (7 µg/m3).
11.2.2.3 VI Pathway Evaluation
The VI pathway evaluation for Building 18224 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 18224 is located within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 15 feet bgs or less. The building is relatively airtight during normal operations, although two rollup garage doors may be left open during warmer weather. Several floor drains were noted within the building and the basement was flooded
Air Force Civil Engineer Center 11-5 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
during both sampling events. Intrusion of groundwater into the basement suggests the potential for a complete VI pathway. No non-VI ambient air COI contaminant sources were identified.
Upward (i.e., negatively pressurized building interior) sub-slab air pressure gradients (0.002 in- Hg) were identified at two soil gas sample locations: 18224-SG001 (sample start and end) and 18224-SG002 (sample start) (see Table 7.1).
TCE was detected in indoor air during FSE1 and FSE2. PCE was detected in indoor and outdoor air only during FSE2. The maximum results for indoor air are at least one order of magnitude higher than outdoor air for TCE and PCE. TCE and PCE were both detected in soil gas during FSE1. There is no spatial bias apparent in the locations of the PCE and TCE detections in ambient air or soil gas. The ratios between the maximum detected concentrations in soil gas and indoor air for PCE:TCE include the following:
• Soil gas = 1:9; • Indoor air (FSE1) = only TCE detected; and • Indoor air (FSE2) = 2.3:1.
The ratios shown above are generally consistent for FSE1, but are reversed for FSE2.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 18224. The presence of potentially contaminated groundwater in the basement provides an unrestricted pathway for VI migration into the building.
11.2.2.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 18224 has been revised to indicate a potentially complete VI pathway for PCE and TCE. The revised CSM is shown in Figure 11.7.

11.3.1 Building 17534
The Building 17534 Large Airframe Maintenance facility is an operational commercial/industrial use aircraft maintenance facility that includes offices on several floors in the northern portion and a large aircraft hangar in the southern portion. The building is occupied by approximately 10 people on a normal workweek day shift work basis (Monday - Friday, 10 hours per day). Floor penetrations include floor drains and a mechanical room sump.
PID detections up to 6 parts ppm were noted in floor drains and ambient air near a solvent parts degreaser in the northeastern portion of the building during the building survey. Chemicals stored at the facility include acetone, aircraft cleaners/degreasers, and aircraft sealants. The solvent in the parts washer was identified as MIL-PRF-680 Type II, which consists of naphtha/synthetic isoparaffinic hydrocarbons (petroleum distillates).
Air Force Civil Engineer Center 11-6 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Building 17534 is located entirely within the groundwater contamination plume boundary and COIs include: 1,1-DCE; 1,1,1-TCA; benzene; cis-1,2-DCE; PCE; and TCE. The depth to groundwater is approximately 45 feet bgs.
11.3.1.1 VI Sampling Results
Ambient air and soil gas results for Building 17534 are summarized in Table 11.9 and shown in Figure 11.8. Complete analytical results are provided in Table 11.10 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
Several COIs, including 1,1,1-TCA, benzene, PCE, and TCE were detected in indoor air during both sampling events. One COI, cis-1,2-DCE, was detected only during FSE2. Benzene was the only indoor air COI that exceeded its industrial indoor air PSL. Benzene was the only COI detected in outdoor air during FSE1. COIs detected in outdoor air during FSE2 include 1,1,1- TCA, benzene, PCE, and TCE. Soil gas COIs detected during FSE1 included 1,1,1-TCA, benzene, PCE, and TCE. No soil gas results were greater than their industrial soil gas PSLs.
11.3.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.08 and the cumulative cancer risk was equal to 1x10-6 (see Table 10.1) for an indoor worker at Building 17534.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.57 µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10-hour work day (7 µg/m3).
11.3.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 17534 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 17534 is located entirely within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 45 feet bgs. The building is relatively airtight during normal operations. Floor drains and a sump were noted within the building. No non-VI ambient air COI contaminant sources were identified.
Sub-slab air pressure gradients do not apply to Building 17534, as all soil gas samples were collected from near-slab locations due to the presence of an in-slab heating system at the building (see Table 7.1).
1,1,1-TCA, benzene, PCE, and TCE were detected in soil gas and indoor air during FSE1 and FSE2. Benzene was the only COI detected in outdoor air during FSE1, and the maximum
Air Force Civil Engineer Center 11-7 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
concentration was higher than the maximum indoor air result. Outdoor air maximum concentrations were less than indoor air for the same COIs during FSE2. There is no spatial bias apparent in the locations of these COI detections in ambient air or soil gas.
The ratios between the maximum detected concentrations in soil gas and indoor air among the detected COIs are not consistent. The maximum soil gas concentration for 1,1,1-TCA is higher than all other COIs in soil gas and indoor air. The maximum TCE concentration is higher than benzene and PCE in soil gas, but is not consistently higher than benzene and PCE in indoor air. The ratios of the various maximum concentrations in soil gas and indoor air do not suggest the presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 17534. The consistent detections of 1,1,1-TCA, benzene, PCE, and TCE in soil gas and indoor air suggest VI as a potential source for these contaminants.
11.3.1.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 17534 has been revised to indicate a potentially complete VI pathway for 1,1,1-TCA, benzene, PCE, and TCE. The revised CSM is shown in Figure 11.9.

The building is occupied by up to 200 people on a normal workweek basis (Monday-Friday) with three shifts per day (10 hours each). Floor penetrations include numerous floor drains, an in-floor sump/vault, and concrete floor seams. Building 16716 is located partially within the groundwater contamination plume boundary and COIs include PCE and TCE. The depth to groundwater is approximately 55 feet bgs.

PCE was detected in all four indoor air samples during both FSE1 and FSE2. TCE was detected in one of four indoor air samples during FSE1 and three of four indoor air samples during FSE2. None of the indoor air COI concentrations exceeded industrial indoor air PSLs. For outdoor air, PCE and TCE were not detected during FSE1. PCE was detected in all outdoor air samples during FSE2. TCE was not detected in outdoor air during FSE2. PCE was detected in three of four soil gas samples and TCE was detected in one of four soil gas samples during FSE1. PCE was detected in soil gas at concentrations exceeding its industrial soil gas PSL. Ethylbenzene

and total xylene were the only non-COIs detected at concentrations greater than their respective industrial soil gas PSLs.
11.4.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.03 and the cumulative cancer risk was below 1x10-4 at 1x10-7 (see Table 10.1) for an indoor worker at Building 16716.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.25 µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10-hour work day (7 µg/m3).
11.4.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 16716 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
The southern half of Building 16716 is located within the buffer zone of a VOC groundwater contamination plume with the depth to groundwater approximately 55 feet bgs. The building is relatively airtight during normal operations. Floor penetrations include numerous floor drains, an in-floor sump/vault, and concrete floor seams. No non-VI ambient air COI contaminant sources were identified.
Upward (i.e., negatively pressurized building interior) sub-slab air pressure gradients were identified at soil gas sample location 16716-SG001 (sample start 0.173 in-Hg and sample end 0.171 in-Hg) and at 16716-SG002 (sample start 0.002 in-Hg) (see Table 7.1).
The maximum PCE detections in soil gas during FSE1 and indoor air during both sampling events occurred at collocated sample locations 16716-SG001 and 16716-AA001, in the southeastern corner of the facility. This soil gas location also had the consistent upward sub-slab pressure gradients noted above. There is no other spatial bias apparent in the locations of COI detections in ambient air or soil gas. The ratios between the maximum detected concentrations in soil gas and indoor air for PCE:TCE include the following:
• Soil gas = 99:1; • Indoor air (FSE1) = 7.3:1; and • Indoor air (FSE2) = 4:1.
The ratios between the maximum detected concentrations in soil gas and indoor air among the COIs are relatively consistent, with the PCE concentration being higher in all cases. The ratios
Air Force Civil Engineer Center 11-9 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
of the various maximum concentrations in soil gas and indoor air suggest the potential presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 16716. The consistent detections of PCE in soil gas and indoor air suggest VI as a potential source for these contaminants, especially in the southeastern portion of the facility.
11.4.1.4 Conceptual Site Model

PID detections up to 3.3 ppm and a general chemical odor were noted in ambient air throughout the building during the building survey, with no obvious source associated with stored materials or operations. The building survey also noted a lack of any significant ventilation. Building 12755 is located partially within the groundwater contamination plume boundary and TCE is the only COI. The depth to groundwater is approximately 45 feet bgs.
11.5.1.1 VI Sampling Results
Ambient air and soil gas results for Building 12755 are summarized in Table 11.13 and shown in Figure 11.12, and summarized below. Complete analytical results are provided in Table 11.14 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
TCE was only detected in indoor air and outdoor air during FSE2. TCE was detected in all soil gas samples during FSE1. None of the indoor air or soil gas TCE concentrations exceeded their respective industrial PSLs. Carbon tetrachloride and chloroform were the only non-COIs with soil gas results greater than industrial soil gas PSLs.
11.5.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.03 and the cumulative cancer risk was below 1x10-4 at 7x10-8 (see Table 10.1) for an indoor worker at Building 12755.

11.5.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 12755 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 12755 is located within the buffer zone of a VOC groundwater contamination plume with the depth to groundwater approximately 45 feet bgs. The building is relatively airtight during normal operations. Floor penetrations included concrete floor seams and cracks. No non- VI ambient air COI contaminant sources were identified.
One downward (i.e., positively pressurized building interior) sub-slab air pressure gradient was identified at soil gas sample location 12755-SG002 (sample end 0.002 in-Hg) (see Table 7.1).
Although TCE was detected in all soil gas samples during FSE1, it was only detected in indoor air during FSE2. Considering the apparent bias of increased ambient air concentrations during the winter season (see Section 10.3), the results could indicate the presence of a complete VI pathway. There is no spatial bias apparent in the locations of COI detections in ambient air or soil gas.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 12755. The consistent detections of TCE in soil gas, and detections in indoor air during the winter season, suggest VI as a potential source for these contaminants in indoor air.

11.6.1.1 VI Sampling Results
Ambient air and soil gas results for Building 13272 are summarized in Table 11.15 and shown in Figure 11.14. Complete analytical results are provided in Table 11.16 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
BTEX, GRO, and naphthalene were detected in indoor air during FSE1 and FSE2. Benzene, ethylbenzene, GRO, naphthalene, and total xylenes had maximum detected indoor air COI concentrations that exceeded the industrial indoor air PSLs. All COIs were detected in outdoor air, except for naphthalene, which was not detected during FSE2. All COIs, except naphthalene, were detected in soil gas during FSE1. PCE was the only non-COI detected at a concentration greater than its industrial soil gas PSLs.
11.6.1.2 Indoor Air Risk Evaluation
Following ADEC guidance (ADEC, 2016) regarding calculating cumulative risk at sites where petroleum constituents are present, maximum concentrations of indicator compounds (COIs benzene, toluene, ethylbenzene, xylenes, and naphthalene) were used to estimate risks. Based on the maximum detected indoor air results, the total HI was below 1 at 0.3 and the cumulative cancer risk was below 1x10-4 at 1x10-5 (see Table 10.1) for an indoor worker at Building 27369.
11.6.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 13272 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Floor penetrations include multiple floor drains, a mechanical room sump, and floor seams. Building 13272 is located entirely within the groundwater petroleum contamination plume boundary with the depth to groundwater of approximately 30 feet bgs. The building is airtight during normal operations, although rollup doors are present in the garage.
Neutral sub-slab air pressure gradients (i.e., no measurable pressure difference) were indicated during soil gas sampling (see Table 7.1).
BTEX, GRO, and naphthalene were detected in indoor and outdoor air during FSE1 and FSE2, with indoor air concentrations higher than outdoor air concentrations during both sampling events. With the exception of naphthalene, all other COIs were detected in soil gas during FSE1. The highest indoor air concentrations for several COIs were detected in the indoor air sample located in the garage (location 13272-AA001) suggesting that vehicle fuel could be contributing to these results at this location. However, an elevated concentration for GRO was also detected in the southeastern portion of the building (location 13272-AA004).
Air Force Civil Engineer Center 11-12 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
The ratios between maximum detected concentrations for select COIs in soil gas, indoor air, outdoor air include the following (respectively):
• Soil gas (FSE1): o 15.7:1 (toluene:benzene) o 7.3:1 (total xylenes:ethylbenzene) • Indoor air (FSE1): o 4.3:1 (toluene:benzene) o 5.4:1 (total xylenes:ethylbenzene) • Indoor air (FSE2): o 8:1 (toluene:benzene) o 10.4:1 (total xylenes:ethylbenzene) • Outdoor air (FSE1): o 6:1 (toluene:benzene) o 4.9:1 (total xylenes:ethylbenzene) • Outdoor air (FSE2): o 4.9:1 (toluene:benzene) o 4.8:1 (total xylenes:ethylbenzene)
The ratios above indicate the potential for a complete VI pathway based on soil gas and indoor air results. However, the similar ratios for outdoor air suggest one or more of the following possibilities:
• Outdoor air was impacted by discharges from soil gas; • Outdoor air was impacted by discharges from VI-contaminated indoor air; and • Outdoor air was impacted by discharges from an unknown ambient air contamination source of similar characteristics to soil gas.
Ambient conditions associated with outdoor air samples collected at 5 feet above the ground surface should not be equivalent to indoor air with regard to detecting impacts from soil gas. Regardless of weather conditions during sampling, it is not likely that soil gas could be detected at concentrations similar to indoor air during two separate sampling events in samples located along all sides of the building.
The potential for detecting impacts associated with VI-contaminated indoor air discharges via a HVAC system also seems unlikely, especially considering the consistent detections of COIs at locations on all sides of the building.
Based on available information, impacts to outdoor air from a nearby ambient air contaminant source of similar characteristics to soil gas (e.g. petroleum-related) appears to be the most likely scenario. However, this possibility cannot be confirmed based on sampling results and conditions observed during the VI Study.
To support the above evaluation, field photographs showing the outdoor air sample locations are provided in Appendix C (Photographs C.19 through C.22). One small HVAC unit that might discharge indoor air is present near sample location 13272-AA005. No air vents are present near
Air Force Civil Engineer Center 11-13 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
any of the other outdoor air samples. There is no spatial bias apparent in outdoor air sample results relative to the location associated with the air vent.
Average wind speed and direction during the Building 13272 outdoor air sampling events were 4 miles per hour (mph)/south-southwest (sample start) and 3 mph/northwest (sample end) (FSE1) and 1 mph/north-northeast (FSE2). The variable wind directions observed during VI sampling does not support the identification of a specific potential ambient air contamination source in the area.
The BTEX compounds are considered to be the most volatile, and therefore the most mobile of the aromatic hydrocarbons. Naphthalene has a relatively low volatility and is likely to partition to soil or sediment, therefore limiting its mobility in the environment. Based on these characteristics, naphthalene may not be an appropriate indicator for determining VI pathway completeness (as compared to the other COIs).
Two above ground storage tank farms are located in the vicinity of Building 13272, one approximately 2,000 feet to the west and the other approximately 1,500 feet to the northeast. Field photographs collected during the VI Study building survey confirm the tank farm to the west of Building 13272 contains JP-8 (kerosene based jet fuel). The status or contents of the other tank farm are not known.
Regardless of the uncertainties associated with the relationship between indoor and outdoor air results, the presence of multiple COIs in indoor air and soil gas suggest the presence of a potentially complete VI pathway at Building 13272.

11.7.1 Building 27369
The Building 27369 Receiver Site facility is an operational commercial/industrial use facility that includes offices on the first and second floors, and a full basement with several mechanical rooms and a walk-out garage. The building currently houses electronic communications equipment in a portion of the ground floor and is only occasionally occupied by 2-3 people for a few hours at a time. Basement floor penetrations include multiple floor drains, a mechanical room sump, and floor seams. Building 27369 is located partially within the groundwater contamination plume boundary and TCE is the only COI.
An area of shallow soil TCE contamination is present adjacent to and beneath the southern portion of the building. Soil contamination depths vary from approximately 2 to 70 feet bgs, with the shallowest contamination immediately adjacent to the southwestern corner of the

building. The soil contamination is associated with a former UST also located adjacent to the southwestern corner of the building. The depth to groundwater is approximately 65 feet bgs.
11.7.1.1 VI Sampling Results
Ambient air and soil gas results for Building 27369 are summarized in Table 11.17 and shown in Figure 11.16 (ground floor) and Figure 11.17 (basement), and summarized below. Complete analytical results are provided in Table 11.18 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
TCE was detected in indoor air during both sampling events at relatively low estimated (J- qualified) concentrations. None of the indoor air TCE concentrations exceeded the industrial indoor air PSL. TCE was detected in outdoor air only during FSE2 at relatively low estimated (J-qualified) concentrations. TCE was detected in all soil gas samples during FSE1 at concentrations below the industrial soil gas PSL. The only non-COIs in soil gas with results greater than industrial soil gas PSLs included 1,1,2-TCA, benzene, and naphthalene.
11.7.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.008 and the cumulative cancer risk was below 1x10-4 at 2x10-8 (see Table 10.1) for an indoor worker at Building 27369.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.075 J µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10- hour work day (7 µg/m3).
11.7.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 27369 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 27369 is located within the buffer zone of a VOC groundwater contamination plume with the depth to groundwater approximately 65 feet bgs. An area of shallow soil TCE contamination is present adjacent to and beneath the southern portion of the building. Soil contamination depths vary from approximately 2 to 70 feet bgs, with the shallowest contamination immediately adjacent to the southwestern corner of the building. The building is relatively airtight during normal operations. Basement floor penetrations include multiple floor drains, a mechanical room sump, and floor seams. No non-VI ambient air COI contaminant sources were identified.
Air Force Civil Engineer Center 11-15 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Neutral sub-slab air pressure gradients (i.e., no measurable pressure difference) were indicated during soil gas sampling (see Table 7.1). The building is only intermittently occupied, is not cooled during summer, and is heated only minimally during winter.
The detections of TCE in soil gas and indoor air (albeit at low, estimated concentrations) suggest the presence of a complete VI pathway. There is no spatial bias apparent in the locations of COI detections in ambient air or soil gas.
Based on the above lines of evidence, the VI pathway is considered complete at Building 27369. The building is used to house computer servers and is not regularly occupied. No industrial operations are conducted that could provide an alternate source for the detections of TCE in indoor air.

TCE was detected in all indoor air samples during FSE1 and FSE2 at concentrations greater than its industrial indoor air PSL. TCE was not detected in any outdoor air sample during either sampling event. TCE was detected in one soil gas sample at a concentration greater than the industrial soil gas PSLs. Chloroform was the only non-COI with a soil gas result greater than PSLs.
11.8.4.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.4 and the cumulative cancer risk was equal to 1x10-6 (see Table 10.1) for an indoor worker at Building 7309.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (3.4 µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10-hour work day (7 µg/m3).
In general, the calculation of inhalation hazards and risks are independent of age-related factors and are based solely on exposure time, frequency, and duration. For the target analytes, the exception is TCE, for which age-dependent adjustment factors are applied to the cancer risk calculations to account for the greater sensitivity of younger receptors as compared to adults. Given that the non-cancer HIs calculated for the indoor worker under a chronic exposure scenario are less than the target HI of 1, non-cancer HIs to recreational users also would be less than the target value. The chronic exposure scenario results in a cancer risk of 5x10-7 is less than the EPA target risk range. Given the reduced exposure of a recreational user, even with application of age-dependent adjustment factors, it is unlikely that TCE would pose an unacceptable cancer risk.

The VI pathway evaluation for Building 4228 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 4228 is located entirely within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 29 feet bgs. The building is airtight during normal operations and includes a vapor barrier beneath the concrete slab floor. Floor penetrations are limited to floor drains in the restrooms. No non-VI ambient air TCE contaminant sources were identified.
Sub-slab air pressure gradients do not apply to Building 4228, as all soil gas samples were collected from near-slab locations to avoid potential damage to the vapor barrier (see Table 7.1).
Although TCE was detected in indoor air during FSE2, the low estimated concentrations are near the laboratory reporting limit and are lower than the non-detected reporting limit values from FSE1. Combined with the detection of TCE in only one soil gas sample at a low estimated concentration, the sample results do not suggest the presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered incomplete at Building 4228.
11.9.1.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 4228 has not been revised. The CSM is shown in Figure 11.32.
11.9.2 Building 4230
Building 4230 is an operational commercial/industrial use skirted office trailer complex consisting of two connected trailers. The facility is occupied by contractor personnel on a normal workweek day shift basis (Monday - Friday, 9 hours per day). The crawlspace beneath the skirted trailers consists of a soil/gravel surface. A utility conduit was the only floor penetration
Air Force Civil Engineer Center 11-26 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
noted within the trailers. Building 4230 is located entirely within the groundwater contamination plume boundary and TCE is the only COI. The depth to groundwater is approximately 30 feet bgs.
11.9.2.1 VI Sampling Results
Ambient air and soil gas results for Building 4230 are summarized in Table 11.33 and shown in Figure 11.33. Complete analytical results are provided in Table 11.34 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
TCE was detected in indoor air during FSE1 and FSE2 at concentrations greater than industrial indoor air PSLs. TCE was detected in outdoor air only during FSE2. TCE was detected in crawlspace air during both sampling events at concentrations one order of magnitude less than indoor air. TCE was detected in one of two soil gas samples during FSE1 at a concentration less than industrial soil gas PSLs. Carbon tetrachloride was the only non-COI with soil gas results exceeding PSLs.
11.9.2.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was equal to 1 and the cumulative cancer risk was below 1x10-4 at 3x10-6 (see Table 10.1) for an indoor worker at Building 4230.
Regarding short-term exposure to TCE in indoor air, the maximum detected indoor air concentrations of 8.7 µg/m3 (FSE1) and 7.1 µg/m3 (FSE2) are slightly greater than one or both of USEPA’s TCE industrial Indoor Air Response Action Levels of 7 µg/m3 (10-hour work day) and 8 µg/m3 (8-hour work day).
11.9.2.3 VI Pathway Evaluation
The VI pathway evaluation for Building 4230 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 4230 is located entirely within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 30 feet bgs. The building is generally airtight during normal operations. A utility conduit was the only floor penetration noted within the trailers. Underground water and sewer lines that enter the structure in the crawlspace may represent a preferred pathway for VI. No non-VI ambient air TCE contaminant sources were identified.
Sub-slab air pressure gradients do not apply to Building 4230, as all soil gas samples were collected from near-slab locations (see Table 7.1).
Air Force Civil Engineer Center 11-27 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Although TCE was detected in indoor air during both sampling events and in soil gas during FSE1, the crawlspace air concentrations do not support the observed indoor air concentrations relative to a complete VI pathway from soil gas. The indoor air results suggest the presence of a non-VI source for TCE within the trailers.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 4230.
11.9.2.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 4230 has been revised to indicate a potentially complete VI pathway for TCE. The revised CSM is shown in Figure 11.34.

TCE was detected in indoor and outdoor air only during FSE2 at concentrations less than industrial indoor air PSLs. TCE also was detected in soil gas during FSE1 at concentrations less than industrial soil gas PSLs. Only one non-COI (1,2,4-trimethylbenzene) was detected in soil gas at concentrations greater than industrial soil gas PSLs.
11.9.3.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.01 and the cumulative cancer risk was below 1x10-4 at 4x10-8 (see Table 10.1) for an indoor worker at Building 4314.
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.13 µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10-hour work day (7 µg/m3).

11.9.3.3 VI Pathway Evaluation
The VI pathway evaluation for Building 4314 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 4314 is located entirely within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 32 feet bgs. The building is generally airtight during normal operations, although garage doors are present within the hazardous waste storage and paint shop portions of the building. Floor penetrations include floor drains and concrete floor seams. No non-VI ambient air TCE contaminant sources were identified.
One downward (i.e., positively pressurized building interior) sub-slab air pressure gradient was identified at soil gas sample location 4314-SG001 (sample start 0.002 in-Hg) and one upward (i.e., negatively pressurized building interior) gradient was identified at location 4314-SG003 (sample start 0.002 in-Hg) (see Table 7.1).
Indoor and outdoor air TCE detections during FSE2 indicate similar concentrations. The TCE soil gas detections were both located in the paint shop portion of the building. No spatial bias between indoor air or soil gas results is apparent. The results suggest the potential presence of a complete VI pathway, especially in the paint shop portion of the facility.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 4314.
11.9.3.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 4314 has been revised to indicate a potentially complete VI pathway for TCE. The revised CSM is shown in Figure 11.36.
11.9.4 Buildings 5208A/5211A
Buildings 5208A and 5211A are residential duplex units located in the Dallas Housing complex. Building 5208A (sampled during FSE1) and Building 5211A (sampled during FSE2) were included based on their availability as vacant units during the field mobilizations. Building 5208A was not available for sampling during FSE2. The buildings are both located in the northern portion of the Dallas Housing complex approximately 200 feet apart. The construction and floor plans of both units are the same. No floor penetrations or drains were observed. A vapor barrier is present beneath the building slabs (per Aurora Military Housing). Both buildings are located within the ST037 Fairchild Avenue groundwater contamination plume buffer zone and TCE is the only COI. The depth to groundwater is approximately 27 feet bgs.

Ambient air and soil gas results for Buildings 5208A/5211A are summarized in Table 11.37 and shown in Figure 11.37. Complete analytical results are provided in Table 11.38 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
TCE was not detected in any indoor or outdoor air during FSE1 or FSE2. TCE was detected in one soil gas sample during FSE1 at Building 5208A at a concentration less than residential soil gas PSLs. Chloroform was the only non-COI with a soil gas result greater than industrial soil gas PSLs.
11.9.4.2 Indoor Air Risk Evaluation
TCE was not detected in indoor air during either sampling event; therefore, the noncancer HI and cumulative cancer risk were not calculated.
11.9.4.3 VI Pathway Evaluation
The VI pathway evaluation for Buildings 5208A/5211A included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 5208A is located within the buffer zone; the western half of Building 5211A is located within the boundary of a VOC groundwater contamination plume with the depth to groundwater approximately 27 feet bgs. The buildings are generally airtight and include a vapor barrier beneath the concrete slab floor. No floor penetrations or drains were observed.
Sub-slab air pressure gradients do not apply to Buildings 5208A, as all soil gas samples were collected from near-slab locations to avoid potential damage to the vapor barrier (see Table 7.1). Soil gas sampling was not conducted at Building 5211A (only ambient air samples during FSE2).
Although TCE was detected in one of two soil gas samples, no TCE was detected in either building during the respective sampling events. Therefore, the VI pathway is considered incomplete at Buildings 5208A/5211A.

11.9.5.3 VI Pathway Evaluation
The VI pathway evaluation for Building 5223 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
The western quarter of Building 5223 is located within the buffer zone of a VOC groundwater contamination plume with the depth to groundwater approximately 27 feet bgs. The building is generally airtight and includes several garage doors opened intermittently. Floor penetrations include numerous floor drains, a mechanical room sump pit, and concrete floor cracks.
One upward (i.e., negatively pressurized building interior) sub-slab air pressure gradient was identified at soil gas sample location 5223-SG001 (sample start 0.002 in-Hg) (see Table 7.1).
There is no spatial bias apparent among the ambient air sample results. Although TCE was detected in indoor air and outdoor air, the lack of any detections in soil gas suggests the absence of a complete VI pathway.

The building is airtight during normal operations. Floor penetrations include multiple floor drains in the kitchen area and a sump in the basement mechanical room.
A neutral sub-slab air pressure gradient (i.e., no measurable pressure difference) was indicated during soil gas sampling at the single soil gas sample location in the basement mechanical room (see Table 7.1). The remaining soil samples were collected from near-slab locations.
All TCE detections in soil gas, indoor air, crawlspace air, and outdoor air were at relatively low estimated concentrations. Although TCE was detected in soil gas only in the basement sample, its presence in soil gas and indoor air during FSE2 suggests the potential presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 7535.

Building 8574 is not located within a current groundwater contamination plume boundary, although TCE contamination has been identified in soil and groundwater in this area (USAF, 2015a). Soil contamination depths vary from approximately 4 to 67 feet bgs along the northwestern portion of the building in the area of the former UST. The depth to groundwater is approximately 25 feet bgs. The building is airtight during normal operations, although rollup garage doors are present along the north and east sides. Floor penetrations include multiple floor drains and an in-floor vault (possibly associated with a groundwater monitoring well) in the vicinity of the former UST in the northwest corner of the building.
Two upward (i.e., negatively pressurized building interior) sub-slab air pressure gradients were identified at soil gas sample locations 8574-SG001 (sample start 0.002 in-Hg) and 8574-SG003 (sample start 0.002 in-Hg) (see Table 7.1).
The highest TCE detections in soil gas were located in the northwestern portion of the building, closest to the former UST location. Detected TCE concentrations in outdoor air were consistently one to two orders of magnitude lower than indoor air. The presence of TCE in soil gas and indoor air suggest the presence of a complete VI pathway.

Ambient air and soil gas results for Building 11550 are summarized in Table 11.49 and shown in Figure 11.49 (ground floor) and Figure 11.50 (basement). Complete analytical results are provided in Table 11.50 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
BTEX and naphthalene were detected in indoor air during FSE1 and FSE2, at concentrations less than industrial indoor air PSLs during FSE1, and greater than PSLs during FSE2. GRO concentrations exceeded the PSL during FSE1 and FSE2. All of the COIs were detected in outdoor air during FSE1 and all but naphthalene were detected in outdoor air during FSE2. BTEX and GRO were detected in soil gas during FSE1. No soil gas results were greater than their industrial soil gas PSLs.
11.11.3 Indoor Air Risk Evaluation
Following ADEC guidance (ADEC 2016) regarding calculating cumulative risk at sites where petroleum constituents are present, maximum concentrations of indicator compounds (COIs benzene, toluene, ethylbenzene, xylenes, and naphthalene) were used to estimate risks. Based on the maximum detected indoor air results, the total HI was below 1 at 0.1 and the cumulative cancer risk was below 1x10-4 at 1x10-6 (see Table 10.1) for an indoor worker at Building 11550.
11.11.4 VI Pathway Evaluation
The VI pathway evaluation for Building 11550 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
The southeastern portion of Building 11550 is located within the buffer zone of a groundwater contamination plume with the depth to groundwater approximately 25 feet bgs. The building is
Air Force Civil Engineer Center 11-38 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
airtight during normal operations. A mechanical room sump pit is the only basement floor penetration.
Sub-slab air pressure gradients do not apply to Building 11550, as all soil gas samples were collected from near-slab locations (see Table 7.1).
During FSE1, all COIs were detected at similar concentrations in indoor air and outdoor air. The outdoor air results were slightly less than indoor air (see Table 11.49). However, during FSE2, all COI outdoor air results (except for naphthalene) were higher than indoor air. Indoor air concentrations in the basement and on the first floor were relatively consistent during both sampling events. All COIs, except naphthalene, were detected in all soil gas samples during FSE1. There is no spatial bias apparent between the locations soil gas and indoor air detections.
The ratios between maximum detected concentrations for select COIs in soil gas, indoor air, outdoor air include the following (respectively):
• Soil gas (FSE1): o 4:1 (toluene:benzene) o 5.7:1 (total xylenes:ethylbenzene) • Indoor air (FSE1): o 4:1 (toluene:benzene) o 5.3:1 (total xylenes:ethylbenzene) • Indoor air (FSE2): o 11.5:1 (toluene:benzene) o 5.3:1 (total xylenes:ethylbenzene) • Outdoor air (FSE1): o 3.3:1 (toluene:benzene) o 6:1 (total xylenes:ethylbenzene) • Outdoor air (FSE2): o 19:1 (toluene:benzene) o 5.3:1 (total xylenes:ethylbenzene)
The ratios above indicate the possibility for a potentially complete VI pathway based on soil gas and indoor air results. However, the similar ratios for outdoor air suggest one or more of the following possibilities:
• Outdoor air was impacted by discharges from soil gas; • Outdoor air was impacted by discharges from VI-contaminated indoor air; and • Outdoor air was impacted by discharges from an unknown ambient air contamination source of similar characteristics to soil gas.
Ambient conditions associated with outdoor air samples collected at 5 feet above the ground surface should not be equivalent to indoor air with regard to detecting impacts from soil gas. Regardless of weather conditions during sampling, it is not likely that soil gas could be detected at concentrations similar to indoor air during two separate sampling events in samples located along all sides of the building.
Air Force Civil Engineer Center 11-39 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
The potential for detecting impacts associated with VI-contaminated indoor air discharges via an HVAC system also seems unlikely, especially considering the consistent detections of COIs at locations on all sides of the building.
Based on available information, impacts to outdoor air from a nearby ambient air contaminant source of similar characteristics to soil gas (e.g. petroleum-related) appears to be the most likely scenario. This possibility cannot be confirmed, however, based on sampling results and conditions observed during the VI Study.
To support the above evaluation, field photographs showing the outdoor air sample locations are provided in Appendix C (Photographs C.15 through C.18). The HVAC units near sample locations 11550-AA001 and 11550-AA004 are heat exchangers that do not discharge indoor air to the area. A small air vent is present approximately 10-12 feet above sample location 11550- AA002, and a near ground-level air vent is present adjacent to sample location 11550-AA003. There is no spatial bias apparent in outdoor air sample results relative to the locations associated with air vents.
Further, the average wind speed and direction during Building 11550 outdoor air sampling events were calm/NNE (FSE1) and 2 mph/NNW (FSE2). For several COIs, concentrations were higher for the two sample locations along the northern exterior wall (11550-AA001/AA004) versus the other two sample locations to the south and east (see Figure 11.49). This concentration distribution could be evidence of an outdoor air contaminant source generally located to the north of Building 11550.
The BTEX compounds are considered to be the most volatile, and therefore mobile, of the aromatic hydrocarbons. Naphthalene has a relatively low volatility and is likely to partition to soil or sediment, therefore limiting its mobility in the environment. Based on these characteristics, naphthalene may not be an appropriate indicator for determining VI pathway completeness (as compared to the other COIs).
The Building 11568 aircraft fuel pumping station (see Appendix C, Photograph C.23), which is located approximately 675 feet northwest of the northwestern corner of Building 11550 (see Figure 5.12), could be a potential source for ambient air petroleum impacts. Specific characteristics of Building 11568 operations, including the venting of petroleum vapors, are not known.
Regardless of the uncertainties associated with the relationship between indoor and outdoor air results, the presence of multiple COIs in indoor air and soil gas suggest the presence of a potentially complete VI pathway at Building 11550.
11.11.5 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 11550 has been revised to indicate a potentially complete VI pathway. The revised CSM is shown in Figure 11.51.

11.12.1 Building 11551
The Building 11551 3d Wing Weapons and Tactics facility is an operational commercial/industrial use facility that includes offices on the first and second floors and an open hangar work area on the ground floor. The facility is occupied by approximately 75 people on a normal workweek day shift basis (Monday - Friday, 9 hours per day). Floor penetrations include floor drains and an in-floor OWS in the hangar area. PID detections up to 13.7 ppm were noted at the in-floor OWS. Although Building 11551 is not located within the current groundwater contamination plume boundary or buffer zone, it is located in the vicinity of a previously identified area of soil contamination to the west of the building. COIs at Building 11551 include BTEX, GRO, and naphthalene. The depth to groundwater is approximately 25 feet bgs.
11.12.1.1 VI Sampling Results
Ambient air and soil gas results for Building 11551 are summarized in Table 11.51 and shown in Figure 11.52. Complete analytical results are provided in Table 11.52 and PSL screening results are provided in Table 9.6 (indoor air) and Table 9.8 (soil gas).
BTEX, GRO, and naphthalene were detected in indoor air during FSE1 and FSE2; GRO was the only COI in indoor air that exceeded industrial indoor air PSLs. All of the COIs (except naphthalene) were detected in outdoor air during FSE1 and FSE2. All COIs were detected in soil gas during FSE1, and results exceeding industrial soil gas PSLs included TCE, ethylbenzene, naphthalene, and total xylenes.
11.12.1.2 Indoor Air Risk Evaluation
Following ADEC guidance (ADEC, 2016) regarding calculating cumulative risk at sites where petroleum constituents are present, maximum concentrations of indicator compounds (COIs benzene, toluene, ethylbenzene, xylenes, and naphthalene) were used to estimate risks. Based on the maximum detected indoor air results, the total HI was below 1 at 0.06 and the cumulative cancer risk was below 1x10-4 at 2x10-6 (see Table 10.1) for an indoor worker at Building 11551.
11.12.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 11551 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Although Building 11551 is not located within the current groundwater contamination plume boundary or buffer zone, it is located in the vicinity of a previously identified area of soil

contamination to the west of the building. The depth to groundwater is approximately 25 feet bgs. The building is airtight during normal operations. A mechanical room sump pit is the only basement floor penetration. Floor penetrations include floor drains and an in-floor OWS in the hangar area.
Neutral sub-slab air pressure gradients (i.e., no measurable pressure difference) were indicated during soil gas sampling (see Table 7.1).
There is no spatial bias apparent between soil gas and indoor air sample results. The highest indoor air concentrations for all COIs (except total xylene) were found at sample location 11551- AA001, which was located in a smaller separate airspace (versus the other indoor air samples located in the main hangar).
The ratios between maximum detected concentrations for select COIs in soil gas, indoor air, outdoor air include the following (respectively):
• Soil gas (FSE1): o 49:1 (toluene:benzene) o 3:1 (total xylenes:ethylbenzene) • Indoor air (FSE1): o 3.5:1 (toluene:benzene) o 4.3:1 (total xylenes:ethylbenzene) • Indoor air (FSE2): o 10:1 (toluene:benzene) o 4.9:1 (total xylenes:ethylbenzene) • Outdoor air (FSE1): o 3:1 (toluene:benzene) o 6:1 (total xylenes:ethylbenzene) • Outdoor air (FSE2): o 10:1 (toluene:benzene) o 4.9:1 (total xylenes:ethylbenzene)
The ratios above indicate the potential for a complete VI pathway based on soil gas and indoor air results. However, the similar ratios for outdoor air suggest one or more of the following possibilities:
• Outdoor air was impacted by discharges from soil gas; • Outdoor air was impacted by discharges from VI-contaminated indoor air; or • Outdoor air was impacted by discharges from an unknown ambient air contamination source of similar characteristics to soil gas.
Ambient conditions associated with outdoor air samples collected at 5 feet above the ground surface should not be equivalent to indoor air with regard to detecting impacts from soil gas. Regardless of weather conditions during sampling, it is not likely that soil gas could be detected at concentrations similar to indoor air during two separate sampling events in samples located along all sides of the building.
Air Force Civil Engineer Center 11-42 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
The potential for detecting impacts associated with VI-contaminated indoor air discharges via an HVAC system also seems unlikely, especially considering the consistent detections of COIs at locations on all sides of the building.
Based on available information, impacts to outdoor air from a nearby ambient air contaminant source of similar characteristics to soil gas (e.g., petroleum-related) appears to be the most likely scenario. This possibility cannot be confirmed based on sampling results and conditions observed during the VI Study.
To support the above evaluation, field photographs showing the outdoor air sample locations are provided in Appendix C (Photographs C.19 through C.22). No air vents are present near any of the outdoor air samples. There is no spatial bias apparent in outdoor air sample results relative to the locations associated with air vents.
Average wind speed and direction during the Building 11551 outdoor air sampling events were 2 mph/NNW (FSE1) and 5 mph/NW (FSE2). The highest outdoor air COI concentrations were identified in the sample located along the southern exterior wall (11550-AA005). The COI concentrations were similarly low in the remaining outdoor air samples located to the west, north, and east (see Figure 11.52).
The BTEX compounds are considered to be the most volatile, and therefore more mobile, of the aromatic hydrocarbons. Naphthalene has a relatively low volatility and is likely to partition to soil or sediment, thereby limiting its mobility in the environment. Based on these characteristics, naphthalene may not be an appropriate indicator for determining if the VI pathway is complete (as compared to the other COIs).
The Building 11568 aircraft fuel pumping station (see Appendix C, Photograph C.23), which is located approximately 175 feet west of the southwestern corner of Building 11551 (see Figure 5.12), could be a potential source for ambient air petroleum impacts. Specific characteristics of Building 11568 operations, including the venting of petroleum vapors, are not known.
Regardless of the uncertainties associated with the relationship between indoor and outdoor air results, the presence of multiple COIs in indoor air and soil gas suggest the presence of a potentially complete VI pathway at Building 11551.

12.0 JBER-R FINDINGS AND RESULTS
This section discusses the findings and results of the VI study at JBER-R sites and BOIs including sample results, indoor air risk evaluation, VI pathway evaluation, and revised CSM.
FOD for JBER-R COIs in indoor air and outdoor air samples are presented in Table 12.1. The table includes separate totals for both field sampling events. The indoor air FODs remained the same or increased during FSE2 for all COIs. The outdoor air FODs increased during FSE2 for all COIs. The total FODs for FSE2 were higher for indoor air and outdoor air.
Average sample concentrations for all COIs in indoor air show a general increase from FSE1 to FSE2 (see Table 12.2). For outdoor air, results for benzene and TCE increased, while results for PCE decreased slightly during FSE2.
The following sections summarize ambient air and soil gas results for each site and BOI included in the JBER-R field data collection program. Ambient air results are shown for site-specific COIs for each field sampling event. Due to the relatively long list of analytes included in the soil gas analyses, the results shown below are limited to site-specific COIs to support the VI pathway evaluation.

12.1.1 Building 726
Building 726 is an operational commercial/industrial use laundry and dry cleaning facility that includes offices and work areas on the ground floor, and a basement. The building is occupied by approximately 50-60 people on a normal workweek day shift basis (Monday - Friday, 9 hours per day). Basement floor penetrations include floor drains, a mechanical room sump pit, concrete floor cracks, and utility conduits. First floor penetrations include floor drains, a floor drain sump pit, and concrete floor cracks. PID detections up to 10.5 ppm were noted in the basement sump pit and ambient air, and in a first floor drain. The building survey team also noted an organic chemical solvent odor. Drums containing ExxonMobil DF-2000 dry cleaning solvent were identified at Building 726 during the building survey. The DF-2000 dry cleaning solvent is chemically similar to the MIL-PRF-680 Type II solvents identified in solvent parts cleaners in Buildings 6211 and 17534, and consists of naphtha/synthetic isoparaffinic hydrocarbons (petroleum distillates). Available historical information confirms that PCE was used as a dry cleaning solvent at Building 726 until the mid to late 1990s (U.S. Army, 1998), but no information is available regarding when PCE use was discontinued. Building 726 is located partially within the DA089 groundwater contamination plume boundary and PCE is the only COI. The depth to groundwater is approximately 70 feet bgs.
12.1.1.1 VI Sampling Results
Ambient air and soil gas results for Building 726 are summarized in Table 12.3 and shown in Figure 12.1 (ground floor) and Figure 12.2 (basement). Complete analytical results are provided in Table 12.4 and PSL screening results are provided in Table 9.7 (indoor air) and Table 9.9 (soil gas).
Air Force Civil Engineer Center 12-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
PCE was detected in indoor air samples during FSE1 and FSE2 at concentrations greater than industrial indoor air PSLs, and also was detected in all outdoor air samples during both sampling events. A marked difference in concentrations were observed between the indoor air samples collected in the basement and the indoor air samples collected on the first floor. PCE concentrations in indoor air samples from the first floor ranged from 0.15 µg/m3 to 0.87 µg/m3 over both field events. PCE concentrations in indoor air in the basement varied widely, ranging from 0.47 µg/m3 to 570 µg/m3. PCE was detected in all soil gas samples during FSE1. No soil gas results were greater than their industrial soil gas PSLs.
12.1.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, which was for a sample location in the basement, the total HI exceeded 1 at a value of 3 and the cumulative cancer risk was below 1x10-4 at 1x10-5 (see Table 10.1) for an indoor worker at Building 726. Concentrations exceeding the industrial indoor air PSLs during FSE1 and FSE2 were collected at two sampling locations in the basement (726-AA008 and –AA009). PCE concentrations in indoor air on the first floor were below PSLs.
Increased concentrations of PCE were observed in indoor air samples collected from the Building 726 basement during FSE2, as compared with concentrations from FSE1.
Building 726 currently operates as a laundry and dry cleaning facility that includes a basement and offices and work areas on the first floor. The basement of Building 726 is not regularly occupied. The building is occupied on a normal workweek day shift basis. Detected concentrations of PCE in indoor air samples from the first floor of Building 726 varied from 0.22 to 0.87 µg/m3 during FSE2, which produce total non-cancer HIs of 0.005 and 0.02, respectively.
Based on the results of the risk assessment, the estimated HI for PCE in indoor air only exceeded the non-cancer threshold of 1 for an indoor worker in the basement of Building 726 and assumed the basement was occupied 8 hours per day, 250 days per year for 25 years. The estimated non- cancer HI did not exceed the threshold of 1 for the indoor worker on the first floor.
12.1.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 726 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
The northwestern portion of Building 726 is located within a current groundwater VOC contamination plume boundary with the depth to groundwater approximately 70 feet bgs. The building is generally airtight during cold weather, however, windows and doors are often left open during operating hours. Basement floor penetrations include floor drains, a mechanical
Air Force Civil Engineer Center 12-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
room sump pit, concrete floor cracks, and utility conduits. First floor penetrations include floor drains, a floor drain sump pit, and concrete floor cracks.
Sub-slab air pressure gradients do not apply to Building 726, as all soil gas samples were collected from near-slab locations (see Table 7.1).
The highest PCE concentration, by one order of magnitude, was identified in the northernmost sample location (nearest to the groundwater contamination plume boundary). The highest indoor air sample result for PCE also was located in the northernmost portion of the basement. Basement indoor air concentrations also were higher than first floor indoor air concentrations. These results suggest the presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered complete at Building 726.
12.1.1.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 726 has been revised to indicate a complete VI pathway for PCE. The revised CSM is shown in Figure 12.3.
12.1.2 Building 728
Building 728 is an operational commercial/industrial use skirted office trailer complex consisting of two connected trailers. The facility is occupied by approximately 6 contractor personnel on a normal workweek day shift basis (Monday - Friday, 9 hours per day). The crawlspace beneath the skirted trailers consists of a soil/gravel surface. A utility conduit was the only floor penetration noted within the trailers. Most of Building 728 is located within the DA089 groundwater contamination plume boundary and PCE is the only COI. The depth to groundwater is approximately 70 feet bgs.
12.1.2.1 VI Sampling Results
Ambient air and soil gas results for Building 728 are summarized in Table 12.5 and shown in Figure 12.4. Complete analytical results are provided in Table 12.6 and PSL screening results are provided in Table 9.7 (indoor air) and Table 9.9 (soil gas).
PCE was detected in indoor air at concentrations less than industrial indoor air PSLs, and in outdoor air and crawlspace air during FSE1 and FSE2. The crawlspace air concentration during FSE1 was almost two orders of magnitude higher than the indoor air concentration but was similar to the maximum detected outdoor air concentration. During FSE2, the concentrations in the crawlspace and indoor air were similar. PCE was detected in both soil gas samples during FSE1, with one result greater than industrial soil gas PSLs. Ethylbenzene and TCE were the only non-COIs with soil gas results that exceeded PSLs.

12.1.2.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.008 and the cumulative cancer risk was below 1x10-4 at 3x10-8 (see Table 10.1) for an indoor worker at Building 728.
12.1.2.3 VI Pathway Evaluation
The VI pathway evaluation for Building 728 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
All of Building 728, except the southeast corner, is located within a current groundwater VOC contamination plume boundary with the depth to groundwater approximately 70 feet bgs. The building is generally airtight. The crawlspace beneath the skirted trailers consists of a soil/gravel surface. A utility conduit was the only floor penetration noted within the trailers.
Sub-slab air pressure gradients do not apply to Building 728, as all soil gas samples were collected from exterior locations (see Table 7.1).
PCE was detected in indoor and outdoor air during both sampling events, with indoor and crawlspace air concentrations higher than outdoor air results during FSE2. The crawlspace air concentration during FSE1 was two orders of magnitude higher than the indoor air concentration. During FSE2, the concentrations in the crawlspace and indoor air were similar. The highest PCE result in outdoor air during FSE1 was located near the crawlspace air sample, and could have been impacted by crawlspace air conditions during sampling. These results suggest the presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered complete at Building 728.
12.1.2.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 728 has been revised to indicate a complete VI pathway for PCE. The revised CSM is shown in Figure 12.5.
12.1.3 Building 730
Building 730 is an operational commercial/industrial use administration facility that includes offices on the first and second floors and a crawlspace with a soil surface beneath the western portion of the building. The building is occupied by approximately 100 people on a normal workweek day shift basis (Monday - Friday, 9 hours per day). Floor penetrations include multiple floor drains, a mechanical room sump pit, and utility conduits. Building 730 is located entirely within the DA089 groundwater contamination plume boundary and PCE is the only COI. The depth to groundwater is approximately 70 feet BGS.

12.1.3.1 VI Sampling Results
Ambient air and soil gas results for Building 730 are summarized in Table 12.7 and shown in Figure 12.6. Complete analytical results are provided in Table 12.8 and PSL screening results are provided in Table 9.7 (indoor air) and Table 9.9 (soil gas).
PCE was detected in indoor air during FSE1 and FSE2. The PCE concentrations exceeded the industrial indoor air PSLs during FSE1 and FSE2. PCE was detected in outdoor air during both sampling events at concentrations two to three orders of magnitude lower than indoor air. PCE was detected in crawlspace air during both sampling events at concentrations greater than in outdoor air. PCE concentrations in soil gas during FSE1 were detected at concentrations greater than the industrial soil gas PSLs. Chloroform and TCE were the only non-COIs with soil gas results that exceeded PSLs.
12.1.3.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was equal to 1 and the cumulative cancer risk was below 1x10-4 at 4x10-6 (see Table 10.1) for an indoor worker at Building 730.
12.1.3.3 VI Pathway Evaluation
The VI pathway evaluation for Building 730 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 730 is located entirely within a current groundwater VOC contamination plume boundary with the depth to groundwater approximately 70 feet bgs. The building is generally airtight. A crawlspace is present beneath the western half of the building. Floor penetrations include multiple floor drains, a mechanical room sump pit, and utility conduits.
Sub-slab air pressure gradients do not apply to Building 730, as all soil gas samples were collected from near-slab locations (see Table 7.1).
PCE was detected in all indoor air, outdoor air, and crawlspace air samples during FSE1 and FSE2. The maximum detected indoor air concentrations at location 730-AA005 during both sampling events were approximately two orders of magnitude higher than the outdoor air concentrations. Also, PCE concentrations in crawlspace air were two orders of magnitude higher than outdoor air concentrations during both sampling events. PCE was detected in all soil gas samples during FSE1, with the highest concentration located along the eastern exterior wall (location 730-SG002). This result generally coincides with the highest indoor sample result located in the mechanical room in the southeastern portion of the building (location 730-AA005). There is no spatial bias apparent in the locations of the other PCE detections in ambient air.
Based on the above lines of evidence, the VI pathway is considered complete at Building 730.

12.1.4 Building 733
Building 733 is an operational commercial/industrial use Naval Reserve facility with offices and work areas on the ground floor. The facility is occupied by approximately 8 people on a normal workweek day shift basis (Monday - Friday, 9 hours per day). Floor penetrations include multiple floor drains. A minor PID detection of 0.2 ppm was noted in ambient air in a garage. A radon mitigation system is present in the southeastern corner of the building. Building 733 is located partially within the DA089 groundwater contamination plume boundary and PCE is the only COI. The depth to groundwater is approximately 70 feet bgs.
12.1.4.1 VI Sampling Results
Ambient air and soil gas results for Building 733 are summarized in Table 12.9 and shown in Figure 12.8. Complete analytical results are provided in Table 12.10 and PSL screening results are provided in Table 9.7 (indoor air) and Table 9.9 (soil gas).
PCE was detected in indoor air at concentrations less than the industrial indoor air PSLs and in outdoor air during FSE1 and FSE2. Indoor air concentrations were higher than outdoor air concentrations during both events. PCE was detected in only one of four soil gas samples at a low estimated (J-qualified) concentration during FSE1. No soil gas results were greater than their industrial soil gas PSLs.
12.1.4.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.002 and the cumulative cancer risk was below 1x10-4 at 6x10-9 (see Table 10.1) for an indoor worker at Building 733.
12.1.4.3 VI Pathway Evaluation
The VI pathway evaluation for Building 733 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Building 733 is located partially within a current groundwater VOC contamination plume boundary with the depth to groundwater approximately 70 feet bgs. The building is generally airtight. Floor penetrations include multiple floor drains. Sub-slab air pressure gradients do not apply to Building 733, as all soil gas samples were collected from near-slab locations (see Table 7.1).
Air Force Civil Engineer Center 12-6 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
PCE was detected in indoor and outdoor air during both sampling events at relatively similar concentrations. There is no spatial bias apparent in the locations of the PCE detections in ambient air or soil gas. PCE was detected in soil gas in only one of three samples with a maximum concentration of 0.45 J µg/m3. Without the consistent detection of PCE in soil gas, the VI sampling results do not support the identification of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered incomplete at Building 733.

12.2.1 Building 740
The Building 740 Heavy Equipment Shop is an operational commercial/industrial use facility with offices on the first and partial second floors, and two high-bay work areas. The building is occupied by approximately 4-6 people on a normal workweek day shift basis (Monday - Friday, 9 hours per day). The building was unoccupied during FSE1 but was occupied by a different contractor during FSE2. Floor penetrations include numerous floor drains and utility conduits, and a mechanical room sump pit. Although Building 740 is not located within a current groundwater contamination plume boundary or buffer zone, a previously identified area of soil contamination is located adjacent to the southwest corner of the building, with maximum concentrations at a depth of 10 to 15 feet bgs (USAF, 2014b). COIs at Building 740 include benzene, PCE, and TCE. The depth to groundwater is approximately 70 feet bgs.
12.2.1.1 VI Sampling Results
Ambient air and soil gas results for Building 740 are summarized in Table 12.11 and shown in Figure 12.10. Complete analytical results are provided in Table 12.12 and PSL screening results are provided in Table 9.7 (indoor air) and Table 9.9 (soil gas).
Benzene, PCE, and TCE were detected in indoor air during FSE1 and FSE2. Benzene and PCE concentrations in indoor air exceeded the industrial indoor air PSLs. Benzene was the only COI detected in outdoor air during FSE1; all three COIs were detected during FSE2. Only benzene and PCE were detected in soil gas; maximum concentrations during FSE1 were below the industrial soil gas PSLs. No soil gas results were greater than their industrial soil gas PSLs.
12.2.1.2 Indoor Air Risk Evaluation
Based on the maximum detected indoor air results, the total HI was below 1 at 0.2 and the cumulative cancer risk was below 1x10-4 at 5x10-6 (see Table 10.1) for an indoor worker at Building 740.
Air Force Civil Engineer Center 12-7 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Regarding short-term exposure to TCE in indoor air, the maximum detected concentration (0.42 µg/m3) is below the USEPA Accelerated Response Action Level (industrial) for a 10-hour work day (7 µg/m3).
12.2.1.3 VI Pathway Evaluation
The VI pathway evaluation for Building 740 included the following lines of evidence:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Although Building 740 is not located within a current groundwater contamination plume boundary or buffer zone, a previously identified area of soil contamination is located adjacent to the southwest corner of the building, with maximum concentrations at a depth of 10 to 15 feet bgs (USAF, 2014b). The depth to groundwater is approximately 70 feet bgs. The building is generally airtight during normal operations and colder weather, although rollup garage doors are present along the east and west sides. Floor penetrations include numerous floor drains and utility conduits, and a mechanical room sump pit.
Sub-slab air pressure gradients do not apply to Building 740, as all soil gas samples were collected from near-slab locations (see Table 7.1).
Benzene, PCE, and TCE were detected in indoor air during FSE1 and FSE2, and in outdoor air during FSE2. PCE and TCE were not detected in outdoor air during FSE1. Indoor air concentrations were higher than outdoor air concentrations during both sampling events. Benzene and PCE were the only COIs detected in soil gas during FSE1. There is no spatial bias apparent in the locations of the COI detections in ambient air or soil gas. The presence of benzene and PCE in soil gas and indoor air suggest the potential presence of a complete VI pathway.
Based on the above lines of evidence, the VI pathway is considered potentially complete at Building 740.
12.2.1.4 Conceptual Site Model
Based on the results of the VI study, the CSM at Building 740 has been revised to indicate a potentially complete VI pathway for benzene and PCE. The CSM is shown in Figure 12.11.

13.0 SUMMARY AND CONCLUSIONS
The results of the JBER VI Study are summarized in Table 13.1, which provides the current use, VI pathway determination and associated COIs, human health risk summary, and applicable COI risk driver COIs (as applicable) for each site and BOI.
This VI study did not address all of the buildings known to overlie sources of VOC contamination in groundwater or soil at JBER that could be associated with VI, as this study was conducted in response to remedy protectiveness questions of the Third Five-Year Review for Fort Richardson (February 2013) and Fourth Five-Year Review for Elmendorf Air Force Base (March 2014a). Separate investigations are underway to evaluate potential VI at other JBER sites and the results of those investigations will be discussed in separate reports.
13.1 VI PATHWAY EVALUATIONS
The VI pathway evaluation conducted for each BOI incorporated multiple lines of evidence including:
• Potential VI source and relative building location; • Physical conditions associated with potential VI; • Presence of a non-VI contaminant source; • Sub-slab air pressure differential gradients; and • Comparison of indoor air, outdoor air, and soil gas VI sample results.
Of the 30 BOIs included in the field data collection program, the pathway evaluation findings are summarized as follows:
• Complete VI pathway - 10 BOIs (JBER-E), 3 BOIs (JBER-R) • Potentially complete VI pathway - 11 BOIs (JBER-E), 1 BOI (JBER-R) • Incomplete VI pathway – 4 BOIs (JBER-E), 1 BOIs (JBER-R)
Table 13.1 provides a summary of the VI pathway evaluation findings for all 30 BOIs addressed during the JBER VI Study.
13.2 RISK ASSESSMENT RESULTS
The following sections summarize the results of the VI risk assessment, including exceedances of the cumulative cancer risk and noncancer HI targets/thresholds, and discussions of the potential for noncancer effects associated with short-term exposure to TCE.
13.2.1 Indoor Air Risk Target Exceedances
Of all 30 BOIs, only one was identified with an estimated cumulative cancer risk or noncancer HI exceeding the risk target levels based on exposure to indoor air. At Building 726 on JBER- R, the total non-cancer HI was estimated at an HI of 3. The risk assessment used the maximum detected PCE concentration of 570 µg/m3 in indoor air, which was from a sample located in the
Air Force Civil Engineer Center 13-1 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
basement during FSE2. The basement in this building is not a regularly occupied space. Detected concentrations of PCE in indoor air samples from the first floor of Building 726 varied from 0.22 to 0.87 µg/m3, which produce total non-cancer HIs ranging from 0.005 to 0.02, respectively.
Based on the results of the risk assessment, the estimated risks for PCE in indoor air only exceeded the non-cancer HI threshold of 1 for the indoor worker in the basement of Building 726, assuming the basement was a regular workspace occupied 8 hours per day, 250 days per year for 25 years. No estimated non-cancer HI exceeding the threshold of 1 for the indoor worker was identified for the first floor. The basement is not occupied by building workers during normal operations.
13.2.2 Evaluation of TCE Results Versus USEPA Response Action Levels
The maximum detected indoor air TCE concentrations at Building 4230 was above the USEPA Accelerated Response Action Level for a 10-hour work day of 7 µg/m3. No other maximum detected indoor air TCE concentration at the remaining BOIs was above the USEPA Accelerated Response Action Level.
The maximum detected concentration at Building 4230 was reported during the FSE1 sampling event at location 4230-AA004. The concentration at this same location during FSE2 was lower at 7.1 µg/m3. Concentrations at the other sampling locations in Building 4230 ranged from 2.9 to 5.6 µg/m3. Additional investigation at Building 4230 is recommended to verify the TCE concentration in indoor air, evaluate potential short-term risk, and determine if action is needed to reduce TCE concentrations in indoor air. As noted in Section 13.3.2 below, TCE was only detected at very low concentrations in the crawlspace air at Building 4230, which could indicate an indoor source of TCE or a preferential pathway via the utility conduit.
As a result of the TCE concentrations detected at Building 4230, JBER initiated response actions including notifications to the JBER Bio-Environmental Engineering Flight (BEE) and the building occupants (Weldin Construction, LLC). JBER will continue to coordinate with the regulatory agencies on the response actions at Building 4230, which will be addressed in a separate report.
13.3 UNCERTAINTIES AND ADDITIONAL WORK RECOMMENDATIONS
The following sections discuss uncertainties and additional work recommendations identified during the evaluations of the JBER VI Study results.
13.3.1 Uncertainties
Uncertainties identify factors that could impact the current and future evaluation of VI study results due to site-specific conditions or data gaps. The sections below describe uncertainties associated with the results of the JBER VI Study.
Air Force Civil Engineer Center 13-2 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
13.3.1.1 Seasonal Variation in Indoor Air Results
The presence of increased indoor air COI concentrations during the colder winter season at JBER (FSE2), as compared to the warmer fall season (FSE1), is consistent with conditions described in a USEPA report on the fluctuation of indoor radon and VOC concentrations due to seasonal variations referenced in Section 10 (USEPA, 2012). The USEPA study concluded that lower VOC concentrations were observed in indoor air during the warmer summer months. The study also concluded that complex concentration trends among individual VOCs may be present.
The potential for elevated indoor air COI concentrations during the winter season at JBER should be considered when planning future VI investigations to ensure representative maximum indoor air and/or sub-/near-slab COI concentrations, and associated estimated risks, are identified.
13.3.1.2 Building 4230 TCE Contamination Source
Although the VI sample results identified the presence of TCE in indoor air, crawlspace air, and soil gas at Building 4230, the crawlspace air concentrations did not appear to be high enough to be solely responsible for the documented impacts to indoor air. Underground water and sewer lines that enter the structure in the crawlspace may represent a preferred pathway for VI. If a continuing source for TCE in indoor air is present within one or both of the trailers, then it will not be possible to isolate the potential impact to indoor air due to VI alone.
Additional work is recommended to increase the understanding of indoor air conditions and possibly identify the source for TCE within the trailer interiors. If a source for TCE is identified and mitigated, then additional indoor air and crawlspace air sampling may be warranted to confirm the presence or absence of a complete VI pathway, and to isolate the potential contribution of TCE to indoor air due to VI (if a complete pathway is confirmed).
13.3.1.3 Buildings 11550 and 11551 VOC Contamination Source
Determining potential impacts to indoor air due to VI at Buildings 11550 and 11551 was not possible because of the potential for an exterior source of contaminants impacting ambient air in this area. Although petroleum-related VOCs and GRO were identified in soil gas and indoor air at these buildings, they also were detected in outdoor air (some at concentrations greater than indoor air). These conditions prevent the discrimination of contaminant contributions to indoor air from VI alone.
Although the risk assessment did not identify any estimated risks that exceeded target cancer risks or the noncancer HI threshold, additional work may be warranted to identify a potential source of contaminants in outdoor air in this area. If a source of contamination is identified, then additional VI sampling could be conducted to determine if the VI pathway is contributing to indoor air concentrations at Buildings 11550 and 11551.
13.3.1.4 Dallas Housing Complex Winter Sampling Event
As described in Section 7.4.9.4, three of the four indoor air samples collected at Dallas Housing complex Building 5211A during FSE2 were determined to be unusable due to the presence of
Air Force Civil Engineer Center 13-3 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
ambient VOCs associated with carpet cleaning activities conducted within 48 hours of sample collection. The fourth indoor air sample, located in the garage, was not impacted by the carpet cleaning and was retained.
Although TCE was not detected in any of the Building 5208A or 5211A garage indoor air samples, the lack of a complete data set for the winter season (e.g., FSE2) at the Dallas Housing units represents a potential data gap that may be addressed by additional sampling during the same winter period in the future.
Considering this data gap, the known presence of sub-slab vapor barriers at the Dallas Housing units, and the lack of TCE detections in soil gas at concentrations greater than PSLs, or in indoor air samples collected during the VI Study, suggests that VI is not occurring at these BOIs.
13.3.1.5 Chlorinated Volatile Organic Compound Degradation Products
As described in Section 3.5, the VI Study COIs identified for each project site were based on contamination previously identified in groundwater and/or soil. Site-specific COIs applied to indoor and outdoor air sample analysis at each BOI included in the field data collection program. The full list of VOCs applied to soil gas sample analysis at all project sites.
For sites where one or more chlorinated VOC COIs were detected in indoor air, an uncertainty exists regarding the potential presence of degradation products of these compounds detected in soil gas at the same sites. Additional characterization will be required to confirm the potential presence of applicable degradation products in indoor air that might be associated with VI.
13.3.2 Additional Work Recommendations
Future work recommendations are based on the determination of a complete, potentially complete, or incomplete VI pathway during the current study:
• Complete: Future work recommended to collect additional indoor air data to verify concentrations remain below target risk levels. An appropriate sampling design to include sample numbers and frequency will be developed to address building-specific conditions, as appropriate. • Potentially Complete: Future work may be necessary to address data gaps/uncertainties to determine if a complete VI pathway is present. • Incomplete: Future work not recommended.
The following sections describe each of the above categories in more detail.
13.3.2.1 Complete VI Pathways
A complete VI pathway was identified at 13 of the 30 BOIs during the JBER VI Study (10 BOIs on JBER-E, and 3 BOIs on JBER-R). A complete VI pathway is based on the presence of COIs in indoor air and soil gas, with soil gas COI concentrations higher than in indoor air, and without any apparent impacts due to outdoor air or other non-VI sources of contamination.
Air Force Civil Engineer Center 13-4 HGL—Vapor Intrusion Study Report for Joint Base Elmendorf-Richardson—Restoration Program Sites, Alaska
Although the risk assessment did not identify any estimated risks that exceeded cancer risk and noncancer targets/thresholds at these buildings (except for the noncancer HI at Building 726 as discussed previously), additional study may be warranted to confirm indoor air concentrations and verify estimated risks do not exceed targets/thresholds (especially if building or contamination source conditions change).
13.3.2.2 Potentially Complete VI Pathways
A potentially complete VI pathway was identified at 12 BOIs during the JBER VI Study (11 BOIs on JBER-E, and 1 BOI on JBER-R). A potentially complete VI pathway was based on the presence of COIs in indoor air and soil gas, with soil gas concentrations greater than in indoor air; however, the VI sampling results and other lines of evidence did not allow for definitive identification of a complete VI pathway.
Although the risk assessment did not identify any estimated risks that exceeded cancer risk or noncancer targets/thresholds at these buildings, additional study may be warranted to confirm indoor air concentrations and/or identify potential or confirmed non-VI (e.g., outdoor or indoor use) sources for COI contamination in indoor air.
13.3.2.3 Incomplete VI Pathways
Incomplete VI pathways were identified at 5 BOIs during the JBER VI Study (4 BOIs on JBER- E, and 1 BOI on JBER-R). An incomplete VI pathway determination was based either on the absence (or infrequent detection at low concentrations [i.e., 1 in 4 samples])of COIs in soil gas (i.e., lack of a source for VI) or an absence in indoor air (i.e., lack of VI impacts to indoor air at the building).
Similar to the potentially complete VI pathways discussed above, additional study may be warranted if building use or contamination source conditions change to confirm incomplete VI pathways.
13.4 FUTURE BUILDING USE AND OCCUPANCY
Available information indicates it is unlikely that the current use for the 30 commercial/industrial BOIs included in the JBER VI Study will change in the future. However, should building use change to include: the presence of sensitive receptors (e.g., children), a change in exposure duration (e.g., continuous occupation), or a change from industrial to residential, further evaluation of the VI pathway and associated risks may be warranted. Also, additional study may be warranted if building use or contamination source conditions change at any BOI.
