1.0 Introduction

This Site Investigation Data Report (Report) describes the field activities and presents the results of the groundwater and soil vapor sampling completed in June 2015 at the former Ivy’s Jiffy Market site located at 40 NW Fourth Street in Madras, Oregon (the Site). This work was done subsequent to the initial Site investigation activities that were completed in May 2014 (discussed in the Site Investigation Data Report; Apex, 2014a) and was done in accordance with the Site Investigation Work Plan (Apex, 2014b) and the Supplemental Site Investigation Work Plan (Apex, 2014c). This work was conducted for the Oregon Department of Environmental Quality (DEQ) under Task 4 of Task Order No. 20-13-21.

1.1 Purpose

The purpose of this work was to obtain additional chemical constituent data (from groundwater and soil vapor at and near the Site) that can be used to assess potential risks posed by the Site to human health and the environment.

1.2 Scope of Work

The scope of work included in the Work Plan consisted of the following tasks:

1) Implementation of the quarterly groundwater monitoring and separate-phase petroleum hydrocarbon (SPH) recovery program (measurement of water and SPH levels in each of 20 groundwater monitoring wells and collection of groundwater samples from wells without SPH);

2) Collection of soil vapor samples from the four vapor monitoring points installed as part of the supplemental Site investigation (SSI);

3) Analyze collected groundwater and soil vapor samples for total petroleum hydrocarbons (TPH) as gasoline (TPHg) and volatile organic compounds (VOCs); and 4) Preparation of a data summary report that discusses the monitoring activities, analytical results and findings, and an evaluation of potential risk based on investigation results.

These activities are discussed in further detail within this report.

2.0 Background

This section presents a description of the Site, the anticipated geology and hydrogeology, and previous work done at the Site. Historical information was obtained from the Environmental Site Investigation report previously prepared for the Site (Osprey, 2009).

2.1 Site Location and Description

The Site is in the City of Madras in the northwest corner of the intersection of Fourth Street (Hwy 26/97) and “B” Street, at an elevation of approximately 2,238 feet above mean sea level (MSL; Figures 1 and 2). The Site is located in the SE 1/4 of the SE 1/4 of Section 2 of Township 11 South, Range 13 East, Willamette Meridian, in Jefferson County, Oregon (tax lots 1300 and 1302). The Site is bounded to the north by a Carson Oil Company CFN Card Lock, to the east by Fourth Street and a former car dealership and service station (Opportunity Foundation property), to the south by “B” Street and a motel (Best Western Madras Inn), and to the west by a mobile home park (Willow Creek Mobile Home Park [Willow Creek]). The Site was developed as a market in 1963. Fuel tanks and associated equipment were added in 1982 (including one 10,000-gallon underground storage tank [UST] and one 12,000-gallon UST). The tanks were decommissioned in 1998 and the property continued to be used as a market until about 2003 when the property was converted for use as a used vehicle sales lot.

2.2 Previous Investigations

The following environmental assessments and UST removal actions have occurred at the Site.

 In May 1991, a line failure was identified in the delivery line to the regular gasoline fuel pump. Several cubic yards of petroleum-impacted soil were removed under DEQ oversight and the delivery lines from each of the fuel tanks were replaced with new fiberglass lines.

 In December 1997, soil impacted by petroleum hydrocarbons was discovered during a subsurface geoprobe investigation. Nine explorations were completed, and four samples collected from the vicinity of the USTs were impacted by up to 1,500 milligrams per kilogram (mg/kg) of total TPHg. Samples collected from along the northern and easterly property boundaries (at depths of 13 feet below ground surface [bgs]) had no detected concentrations of TPH.

 Between January and March 1998, two USTs and associated infrastructure were decommissioned by removal. A total of about 659 tons of petroleum-impacted soil was removed from the Site and disposed of. The impacted soil was encountered between the depths of 13 and 20 feet bgs (the depth of the groundwater table at the time of the excavation). The excavation was backfilled in May/June 1998 (with a layer of visqueen sheeting placed as an excavation demarcation layer).

 In January 1999, six borings (IB1 through IB6) were advanced to depths ranging from 21 to 32 feet bgs. Petroleum impacts were detected in the three boring locations nearest the northern property boundary (at depths ranging from 19.5 to 31 feet bgs), with concentrations generally increasing with depth. Four groundwater monitoring wells were installed during this investigation (MW-1 through MW-4), with screens extending from 15 to 25 feet bgs. Depths to water shortly after installation were between 20 and 22 feet bgs. Petroleum hydrocarbons were detected in each of the four wells, with the highest concentrations found in wells MW-2 and MW-4 (benzene

concentrations as high as 27,600 micrograms per liter [µg/L] and 25,300 µg/L for these wells, respectively).

 In November 2008, five geoprobe explorations were completed at the Site to provide information regarding vertical extent and six groundwater monitoring wells were installed (MW-5 through MW-10; 0.75-inch-diameter wells installed with screens extending from 25 to 45 feet bgs). These wells were installed in response to a regional lowering of the groundwater table that occurred after the first four monitoring wells were installed (observed initially in 2001). Petroleum hydrocarbons (including SPH) were identified in wells MW-5 through MW-9 at thicknesses ranging from a sheen to several inches. Groundwater elevations remained low and monitoring wells MW-1 through MW-4 were dry until 2011 when regional water elevations began to rise.

 A program of routine groundwater monitoring was completed at the Site through the fall of 2012. In the most recent monitoring report (Osprey, 2012), it was noted that SPH was encountered in wells MW-5 and MW-6 (with a thickness of about 5.7 feet in MW-5) and that groundwater elevations had risen so that groundwater was encountered in wells MW-1 through MW-4.

 A program of groundwater monitoring and SPH recovery was initiated by the DEQ, with the first event occurring in December 2013.

 A Site investigation was completed by the DEQ in May 2014, including the installation and sampling of seven groundwater monitoring wells (one upgradient on-site well and six downgradient off-site wells). Impacts from gasoline-range hydrocarbons and petroleum-related VOCs were found to be present at the Site and extending north-northwest (downgradient) off-site beneath the adjacent mobile home park (both dissolved-phase hydrocarbons and SPH). SPH and observed concentrations of benzene in groundwater were found above the vapor intrusion risk-based concentrations (RBCs) for residential and occupational uses, suggesting that exposures may occur at unacceptable concentrations. Additional investigation was recommended to define the extent of petroleum hydrocarbons to the north and northwest of the Site and to assess the potential for unacceptable vapor exposures.

 In September 2014, an SSI was completed to address data gaps encountered during the prior work. Tasks included the installation of two additional groundwater monitoring wells (to define the northern extent of the groundwater contamination plume), the installation and sampling of four soil vapor monitoring points, the inclusion of monitored natural attenuation parameters in a round of groundwater monitoring, and the completion of a pilot study of potentially applicable remediation technologies (soil vapor extraction [SVE], air sparging, and dual-phase extraction [DPE]). As a result of completing the SSI, the downgradient extent of the dissolved-phase petroleum hydrocarbon plume has been defined and generally extends from the vicinity of the Site building off-site to the northwest (beneath several residents of the adjacent mobile home park, but does not continue westward beyond 3rd Street, nor does it impact the vicinity of Willow Creek to the north). The soil vapor samples collected from the vicinity of the Site building and downgradient residential receptors were not impacted by hydrocarbons above the soil gas RBCs. Natural attenuation of the

petroleum hydrocarbons is occurring at the Site (aerobically to the extent that oxygen is available and anaerobically through the bulk of the source area and downgradient), though the rate of biodegradation is likely limited by a scarcity of naturally occurring nitrate. The implementation of enhanced bioremediation to address groundwater contamination may be viable through the addition of oxygen and nutrients (i.e., nitrate). Pilot testing of potential remediation technologies suggests that SVE, air sparging, and DPE would be feasible for implementation at the Site. The implementation of an SVE system would immediately address the potential vapor intrusion risks and would mitigate both residual source-area contamination in the vadose zone and SPH. The inclusion of either air sparging or DPE would accelerate the cleanup of impacted groundwater and DPE would improve the removal of SPH.

2.3 Other Impacted Sites

The Site is located in relatively near proximity to three other sites known to have been impacted by petroleum hydrocarbons, summarized below.

Carson Oil CFN Card Lock. The Carson property is located immediately north of the Site (105 North 4th Street). The property was reportedly developed as a gasoline service station in the 1960s and has continued in this use through the present (under various ownerships and configurations). Between 1999 and 2008, several Site investigations were completed at the property, including around the associated USTs. Two monitoring wells were installed on the property (MW-1 and MW-2) in 2008 and were sampled between 2008 and 2011. It was concluded from the Site investigation data that there was insufficient evidence of a significant release of petroleum hydrocarbons on the Carson property and that impacts to the property were likely originating from upgradient (i.e., to the south or southeast). A No Further Action (NFA) determination was made for the property by the DEQ in October 2013.

Opportunity Foundation/McDonald Auto Sales. The Opportunity Foundation property is located to the east of the Site (across 4th Street). The property was developed as an automobile sales and service facility in the late 1910s. Several gasoline service stations were historically present on the property, and it was reported that the associated tanks and other infrastructure were removed (several tanks were decommissioned by removal in 1991). The property is currently vacant and the buildings associated with the most recent use as an auto dealership (McDonald Auto) were removed in 2002. The current owner (the Opportunity Foundation) entered into a Prospective Purchaser Agreement (PPA) with the DEQ in 2001. Two groundwater monitoring wells currently exist on the property (MW-6 and MW-9), installed as part of the investigation of the Leathers Oil property discussed below (a third well, MW-10, was abandoned in 2003 after being damaged during construction activities on the property). Several other investigations have been completed at the property and a soil removal was completed in 2003 as part of a heating oil tank decommissioning. It has been concluded that there are significant concentrations of petroleum hydrocarbons beneath the property (at or near the depth to groundwater), and the likely source has been

Second Quarter 2015 Site Investigation Data Report Page 4 Former Ivy’s Jiffy Market Site, DEQ Task Order No. 20-13-21 July 16, 2015 2103-00/Task 4

identified as the Leathers Oil property to the east (discussed below). Leathers Oil has apparently taken responsibility for the impacts beneath the property.

Leathers Oil Property. The Leathers Oil property is located at 158 NE 5th Street. The property has been reportedly owned by Leathers Oil since 1975 and has been involved in the retail distribution of gasoline since that time. A release from the UST system at the property was identified in 1991 and multiple Site investigations were completed to characterize the extent and magnitude of the release – including the installation of 13 groundwater monitoring wells between 1994 and 1997 (MW-1 through MW-13, located both on and off of the property, including wells on the Opportunity Foundation property as discussed above). A remediation system (including groundwater air sparging and SVE) was installed in 1994 – operating from 1994 to 1996 and again from 2000 to 2004. Other remediation activities included the removal of 806 tons of petroleum-impacted soil and the removal of SPH via sorbent materials in monitoring wells. A reported total of 5,793 gallons of SPH was removed from the Site during active treatment activities.

Groundwater monitoring associated with the Leathers Oil property has concluded that SPH and dissolved-phase hydrocarbons impacted the property and the adjacent Opportunity Foundation property, with a plume that extended approximately 500 feet to the northwest (to the area of the intersection of 4th Street and “A” Street – perhaps crossing the northeast corner of the Carson Oil property). While it is acknowledged that petroleum contamination remains at the property, the investigation and remediation activities that have been conducted were determined by DEQ to meet the requirements for the Generic Remedy for Simple Risk-Based Cleanups and a conditional NFA determination was made for the property on March 18, 2013.

2.4 Geology and Hydrogeology

The following is a discussion of the topography, geology, and hydrogeology of the Site and vicinity.

Topography. The Site and the immediate vicinity are relatively flat with a gentle slope to the northwest, toward an intermittent drainage (Willow Creek) located about 650 feet north of the Site (an elevation drop of about 8 feet). The ground surface elevation at the Site is about 2,238 feet above MSL.

Regional Geology. The regional geology in the vicinity of the Site has been mapped as the upper Miocene and lower Pliocene Deschutes Formation, which is comprised of volcanic deposits and sedimentary beds resulting from episodic volcanic eruptions. The formation generally consists of course-grained volcanic sandstones, conglomerates, and debris flow breccias interbedded with silicic ignimbrites, air-fall lapillistones, and basalt (Smith, 1987). The United States Department of Agriculture (USDA) soil survey of the Upper Deschutes River Area maps the vicinity of the Site with a deep and well-drained sandy loam and a cobbly substratum.

Second Quarter 2015 Site Investigation Data Report Page 5 Former Ivy’s Jiffy Market Site, DEQ Task Order No. 20-13-21 July 16, 2015 2103-00/Task 4

Local geology as encountered in explorations completed at the Site has included interbedded silts, clays, sands, and gravels.

Regional Hydrogeology. United States Geological Survey (USGS) studies show the regional water table in the vicinity of the City of Madras at a depth of more than 200 feet bgs. A review of Oregon Water Resources Department (OWRD) water well logs show City water wells intercept productive aquifers at depths of between 360 and 470 feet bgs.

Site-Specific Geology. Explorations at the Site and the immediate vicinity generally encountered silty sands and sandy silts through the full depth of each excavation (to depths of up to 47 feet bgs), with occasional gravels and interbedded gravelly layers. Previous explorations in the area have identified hard and expansive materials in borings at depths of between 27 to 35 feet bgs.

Site-Specific Hydrogeology. Historically, shallow groundwater was encountered at the Site at depths of between 16 and 20 feet bgs in 1999 (into which monitoring wells MW1 through MW4 were installed). From 2000 to 2010, water levels decreased to an average of about 37 feet bgs (resulting in the installation of Site monitoring wells MW-5 through MW-10) and rose again in 2011. Previous observations of gradient direction at the Site have been inconsistent and historically collected data are not considered reliable. Groundwater gradients observed at other sites in the area suggest a consistent groundwater gradient of about 0.02 feet per feet (ft/ft) to the northwest. Groundwater encountered during this investigation was encountered at depths ranging from 27.4 to 47.1 feet bgs (elevations ranging from 2189.1 to 2211.2 feet), with a northwesterly gradient that ranges from 0.023 ft/ft to 0.091 ft/ft (with an average of 0.043 ft/ft).

3.0 Pre-Investigation Activities

Site Health and Safety Plan. A Site-specific health and safety plan (HASP) was prepared for the field activities and was included in Appendix B of the Site Investigation Work Plan (Apex, 2014b). The HASP was prepared in general accordance with the Occupational Safety and Health Administration (OSHA) and the Oregon Administrative Rules (OAR). A copy of the HASP was maintained on-site during the field activities.

Property Access. DEQ obtained access agreements with the owners of the properties involved in the site investigation activities, including the Site owner and the adjacent mobile home park west of the Site (Willow Creek). Apex notified the Site tenant (Truce Auto) of the Site investigation activities.

Subcontractor Solicitation. Analytical laboratory services were provided by ESC Lab Sciences (ESC) under their price agreement with the State of Oregon.

Second Quarter 2015 Site Investigation Data Report Page 6 Former Ivy’s Jiffy Market Site, DEQ Task Order No. 20-13-21 July 16, 2015 2103-00/Task 4

4.0 Field Activities and Findings

Work was conducted in general accordance with the Supplemental Site Investigation Work Plan (Apex, 2014c) and the Sampling and Analysis Plan included in the Site Investigation Work Plan (Apex, 2014b). Field activities included collection and analysis of groundwater and soil vapor samples.

4.1 Groundwater Monitoring

Groundwater Levels. Groundwater levels were collected on June 3, 2015 from the Site monitoring wells (MW-1 through MW-18). The wells were opened and the water level was allowed to equilibrate before the measurements were taken. The depth to groundwater and SPH was measured in each well to the nearest 0.01 foot using an electronic water level probe. The measured depths to groundwater and groundwater elevations are included in Table 1. Groundwater elevations are presented on Figure 3. Four of the monitoring wells were dry (MW-1 through MW-4), and SPH was encountered in eight of the monitoring wells (MW-5 through MW-11, and MW-14), with measured thicknesses ranging from a sheen (less than 0.01 foot) in well MW-11, to 3.2 feet in MW-6.

In general, the groundwater elevation data suggest a northwesterly horizontal groundwater flow direction, with an average gradient of 0.046 ft/ft (similar to previous observations).

Groundwater Sampling. Groundwater samples were collected on June 3, 2015. Groundwater samples were not collected from wells that were dry (MW-1 through MW-4), or were impacted by SPH (wells MW-5 through MW-11, and MW-14). The samples were collected with a bladder pump with new tubing using low-flow protocols (MW-1 through MW-5 are smaller-diameter wells that would have required alternative sampling equipment, but were impacted by SPH). Field parameters collected during sampling included temperature, pH, conductivity, dissolved oxygen concentration, and oxidation-reduction potential. Field parameters are summarized in Table 1.

4.2 Soil Vapor Sampling

Soil vapor samples were collected from vapor points VP-1 through VP-4 on June 3, 2015. The sample locations are shown on Figure 2. The samples were collected in laboratory-provided sample containers (6-L Summa canisters) and were each collected over a sampling interval of 30 minutes. The barometric pressure reported by the National Weather Service was decreasing through the sample collection period (from a pressure of 29.97 inches of mercury [inHg] at 1:15 pm to 29.93 inHg at 3:15 pm), and had been stable or decreasing since 10:00 pm the prior day.

Second Quarter 2015 Site Investigation Data Report Page 7 Former Ivy’s Jiffy Market Site, DEQ Task Order No. 20-13-21 July 16, 2015 2103-00/Task 4

5.0 Chemical Analyses and Results

The collected groundwater and soil vapor samples were submitted to ESC in Mount Juliet, Tennessee for analysis on a standard turnaround time. Copies of the analytical laboratory reports are included in Appendix A, along with a quality assurance/quality control (QA/QC) review of the data. The results of the data quality review indicate that the data are of acceptable quality and are suitable for their intended purpose.

5.1 Analyses Performed

The analytical program consisted of the following.

Water Samples. Groundwater samples were analyzed for TPHg by Northwest Method NWTPH-Gx and VOCs by U.S. Environmental Protection Agency (EPA) Method 8260B.

Soil Vapor Samples. The four soil vapor samples were analyzed for petroleum VOCs by EPA Method TO-15.

5.2 Chemical Results

Groundwater Samples. Groundwater results are presented in Table 2 and summarized on Figure 4. Petroleum hydrocarbons were detected in each of the six collected groundwater samples, though the detected concentrations in four of the wells were all below the respective reporting limits. Detections of TPHg ranged from 34 µg/L in MW-12 to 8,300 µg/L in MW-13. VOCs were detected in three of the seven samples, with the relatively highest concentrations being detected in monitoring well MW-13 (with a total VOC concentration of 2,107 µg/L). During the June 2015 monitoring event, benzene was detected only in MW-13 at a concentration of 984 µg/L. In general, the petroleum concentrations detected in MW-13 are lower than they were during the previous monitoring event (March 2015), but are within the range of results that were observed during the 2014 monitoring events.

Soil Vapor Samples. The soil vapor analytical results are presented in Table 3 and are shown on Figure 5. TPHg was detected in two of the four soil vapor samples at concentrations that ranged from 270 micrograms per meter cubed (µg/m3; in VP-4) to 370 µg/m3 (in VP-2). VOCs were detected in each of the four samples, with the relatively highest total VOC concentrations encountered in VP-2 (a total VOC concentration of 219 µg/m3). The concentrations of TPH and VOCs are higher in each of the four samples than were observed in the prior sampling event (March 2015), but are lower than were observed during the December 2014 monitoring event.

6.0 Risk-Based Screening

The following is a risk screening of the chemical data collected during the June 2015 groundwater and soil vapor monitoring event. In general, data from on-site explorations (MW-1 through MW-11; VP-3 and VP-4) were screened against occupational RBCs and off-site explorations (MW-12 through MW-18; VP-1 and VP-2) were screened against residential RBCs (reflecting the difference in current and reasonably likely future land uses in the vicinity of each monitoring point).

6.1 Analytical Data and Risk-Based Screening: Groundwater

Groundwater concentrations were compared to applicable DEQ RBCs (Table 2). Based on the conceptual site model, the potentially applicable RBCs include:

 Residential and occupational vapor intrusion (RBCwi); and

 Residential and occupational volatilization to outdoor air (RBCwo).

Total Petroleum Hydrocarbons. The detected concentrations of TPHg are below the applicable RBCs. The nearest detected concentration of TPH to its applicable RBC is from MW-13 (at 38 percent of the RBC). Eight wells were not sampled due to the presence of SPH and are therefore impacted by TPH at levels that are presumed to exceed RBCs.

Volatile Organic Compounds. Benzene was the only VOC detected during this monitoring event at a concentration that exceeds the relevant vapor intrusion RBC (in the sample from MW-13). The remaining detected analytes were below their respective RBCs. Eight monitoring wells were not sampled due to the presence of SPH and are therefore presumed to be impacted by VOCs at concentrations that exceed RBCs.

6.2 Analytical Data and Risk-Based Screening: Soil Vapor

Sample results from the four soil vapor monitoring points were compared to applicable DEQ RBCs (Table 3). Based on the conceptual site model, the potentially applicable RBCs include residential and occupational vapor intrusion (RBCsv).

While each of the four soil vapor samples had detected concentrations of petroleum hydrocarbons, neither TPHg nor the individual VOCs were detected at concentrations that exceeded their respective RBCs. The closest analyte to its lowest applicable RBC was benzene in sample VP-1 (the farthest downgradient vapor point in the mobile home park) at 3.5 percent of the RBC.

7.0 Conclusions and Recommendations

The conclusions that can be drawn from the June 2015 groundwater and soil vapor monitoring event include the following.

 Petroleum hydrocarbons were detected in perimeter wells (MW-15, MW-16, and MW-18), but the concentrations are below the RBCs by several orders of magnitude (also below the laboratory reporting limits for TPH) and are similar to prior results.

 The thicknesses of SPH encountered in monitoring wells generally decreased compared to the prior event (the aggregate thickness of SPH decreased by 58 percent from the March 2015 event, though MW-6 showed an increase), and the most downgradient well with SPH (MW-14) also showed a reduced thickness during this event (by 36 percent). These changes are within the range of typical variation and do not indicate a trend.

 The detected concentrations of benzene in one well (MW-13) exceeds the residential vapor intrusion RBC. It is presumed that wells impacted by SPH (MW-5 through MW-11, and MW-14) are also impacted by VOC concentrations above RBCs, though groundwater samples were not collected from these wells. No other VOCs exceeded their respective RBCs.

 Soil vapor concentrations increased in the June monitoring event (as compared to the prior event in March), but remain consistently below vapor intrusion RBCs.

7.1 Recommendations for Additional Work

Continued groundwater and soil vapor monitoring is recommended to assess the potential for seasonal variability in concentrations, particularly with regards to the SPH thickness observed in MW-14. The pending implementation of the corrective action for the Site (documented in the Corrective Action Plan, Apex 2015) is expected to address the potential exposure risks associated with the SPH plume.

Appendix A Laboratory Analytical Reports and Data Quality Review

Appendix A – QA/QC Review

This appendix documents the results of a quality assurance/quality control (QA/QC) review of the analytical data for groundwater and soil vapor samples collected in June 2015 for the Former Ivy’s Jiffy Market Supplemental Site Investigation project. Samples were analyzed by ESC Lab Sciences of Mount Juliet, Tennessee. A copy of the analytical laboratory reports are included in this appendix, including:

Report Report Date Sampling Event L769685 June 16, 2015 Groundwater Samples L771018 June 16, 2015 Soil Vapor Samples

The QA review included examination and validation of the laboratory summary reports, including:

 Analytical methods;

 Detection limits;  Sample holding times;

 Surrogates, spikes, and blanks; and

 Sample replicates and other field QA samples.

The QA review did not include a review of raw data.

1.0 Analytical Methods

Chemical analyses on groundwater samples consisted of the following:

 Total petroleum hydrocarbons as gasoline (TPHg) by NWTPH-Gx; and

 Volatile organic compounds (VOCs) by U.S. Environmental Protection Agency (EPA) Method 8260B.

Chemical analyses on soil vapor samples consisted of the following:

 Petroleum VOCs by EPA Method TO-15.

2.0 Quality Assurance Review

The following criteria were evaluated in the standard data quality review process:

 Holding times;

 Method blanks;

 Surrogate recoveries;

Second Quarter 2015 Site Investigation Data Report Page A-1 Former Ivy’s Jiffy Market Site, DEQ Task Order No. 20-13-21 July 16, 2015 2103-00/Task 4 Appendix A – QA/QC Review

 Laboratory control sample/laboratory control sample duplicate (LCS/LCSD) recoveries;

 Matrix spike/matrix spike duplicate (MS/MSD) recoveries; and  Laboratory duplicate and relative percent difference (RPD).

Based on this review, data are considered to be of acceptable quality and are suitable for their intended purposes.

Holding Times. Samples were analyzed within the holding times specified for each analysis method.

Method Blanks. A method – or laboratory – blank is a sample prepared in the laboratory along with the actual samples and analyzed for the same parameters at the same time. It is used to assess if detected contaminants may be the result of contamination of the samples in the laboratory. Analytes were not detected in the laboratory method blanks.

Detection Limits. The reporting limits were consistent with method standards, unless raised as needed for dilution for samples with high analyte concentrations. Several analytes were identified by the laboratory at concentrations that were below the laboratory reporting limit for the compound, but were above the method detection limit. These concentrations are considered to be estimated values and have been flagged accordingly.

Surrogate Recovery. Surrogates are organic compounds that are similar in chemical composition to the analytes of interest and spiked into environmental and batch QC samples prior to sample preparation and analysis. Surrogate recoveries for environmental samples are used to evaluate matrix interference on a sample-specific basis. Surrogate recoveries were within quality control limits.

Laboratory Control Sample. LCS are analyzed by the laboratory to assess the accuracy of the analytical equipment. An LCS sample is prepared from an analyte-free matrix that is then spiked with known levels of the constituents of interest (i.e., a standard). The concentrations are measured and the results are compared to the known spiked levels. This comparison is expressed as percent recovery. Percent recoveries of the LCS were within control limits.

Laboratory Control Sample Duplicate. In addition, a second laboratory control sample (i.e., the LCSD) is prepared as above and analyzed. This is compared to the initial laboratory control sample to assess the precision of the analytical method (i.e., RPD). The LCSD RPDs were within acceptable limits

Matrix Spike and Matrix Spike Duplicate Analyses. MS/MSD analysis involves two aliquots of an environmental sample that are spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. These analyses are used to assess the potential for matrix interference with recovery or detection of the constituents of interest and the accuracy of the

The RPD between the MS and MSD is calculated. Percent recoveries of the MS/MSD analyses were generally within control limits.

Field Duplicate. A field duplicate is a second field sample collected from a selected sample location. Field duplicate samples serve as a check on laboratory quality as well as potential variability of the sample matrix. The field duplicate is analyzed and compared to the first sample to assess the precision of the analytical method. This comparison can be expressed by the RPD between the original and duplicate samples. The field duplicate sample for groundwater was collected from well MW-15 (DUP-1). RPDs for the original and duplicate could not be determined as the results were all non-detect in both samples.

Conclusion. In conclusion, the QA objectives have been met and the data are of sufficient quality for use in this project.

Page 16 of 26 Attachment B Explanation of QC Qualifier Codes

Qualifier Meaning ______J (EPA) - Estimated value below the lowest calibration point. Confidence correlates with concentration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable "unless qualified as 'R' (Rejected)."

Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses. TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.

The data package includes a summary of the analytic results of the quality control samples required by the SW-846 or CWA methods. The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report.

Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier.

Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples.

Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.

Page 10 of 16 Attachment B Explanation of QC Qualifier Codes

Qualifier Meaning ______B (EPA) - The indicated compound was found in the associated method blank as well as the laboratory sample. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable "unless qualified as 'R' (Rejected)."

Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses. TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.

The data package includes a summary of the analytic results of the quality control samples required by the SW-846 or CWA methods. The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report.

Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier.

Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples.

Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.
