1-2 1.0 INTRODUCTION

CB&I FEDERAL SERVICES LLC PERFORMANCE MONITORI 2.0 SITE BACKGROUND

Site 8 is located at the northern portion of the former Pease AFB (Figure 1). The former Pease AFB Fire Department utilized two FDTAs during operational years. FDTA1 was

utilized from 1956 to 1961, and FDTA2 (Site 8) was utilized from 1961 to 1988 (Agency for NG PLAN FOR Toxic Substances and Disease Registry, 1999 and EPA, 1994). Firefighters were trained at these FDTAs to extinguish residential type fires and fires fueled by waste oils, solvents, and

fuels (CH2M Hill, 1984). COMPO PERFLUORINATED

The Site 8 Groundwater Management Zone (GMZ) is approximately 25 acres, with the source area originally consisting of approximately 11 acres (Figure 2). This GMZ was

established to monitor groundwater quality and treatment based on historical activities related to Site 8 and the natural groundwater flow. In 1994, the Record of Decision for Site 8 UNDS 00536 -PL- CBI

• (ROD; Roy F. Weston, 1994) presented the selected remedy for the site that addressed the volatile organic compounds in soils and the capture of the dissolved-phased contamination in

February 2016 overburden groundwater to prevent continued migration of contaminated groundwater to • bedrock. The selected remedy alternative included the installation of a soil vapor extraction Revision 0

• (SVE) system for the treatment of source soils and an on-site GWTS for the long-term treatment of ROD-related contaminants of concern (COCs). Draft Final •

2.1 Site 8 PFC Sampling As part of the U.S. Air Force’s ongoing efforts to evaluate for emerging contaminants, non- Task Order No. 0010 COC compounds are evaluated to confirm if present at the site. Three emerging contaminants were identified as possible chemicals that could have been released at the Site 8, which included 1,4-dioxane, and the PFCs perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Contract FA8903 No. 8580 , - 09 -D- There are no promulgated New Hampshire Ambient Groundwater Quality Standards or EPA Maximum Contaminant Limits for PFCs; therefore, the EPA’s Provisional Health Advisories for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) (Provisional Health Advisories [PHAs]; 2009) that were developed to protect against potential risk from exposure to these chemicals through drinking water are used to serve as an informal technical guidance to assist federal, state, and local officials in response to an urgent or rapidly developing drinking water contamination. The PHA values for PFOA and PFOS are 0.4 and 0.2 micrograms per liter (µg/L), respectively.

In 2013, two rounds of sampling were conducted during June and September at a total of 21 locations to determine if 1,4-dioxane, PFOA, and PFOS were present in groundwater at Site 8 and at a downgradient surface water location. The sample locations between the two

CB&I FEDERAL SERVICES LLC

sampling events included 13 overburden wells, 7 bedrock wells, and the GWTS effluent. A PERFORMANCE MONITORI surface water sample was collected during the September sampling event only at Watering Spring (misidentified as Pickering Spring during sampling). Samples were analyzed for 1,4- dioxane by SW-846 Method 8270D-SIM and PFOA/PFOS according to EPA Method 537.1.

During the June 2013 sampling event, 19 locations were sampled including 11 overburden NG PLAN FOR wells, 7 bedrock wells, and the GWTS effluent. 1,4-dioxane was well below any known standards in samples collected from the 19 locations. As a result, no further action was

required for the investigation of 1,4-dioxane. However, both PFOA and PFOS were detected COMPO PERFLUORINATED in all samples collected. The PFOA and PFOS concentrations ranged from 0.0055 to 120 µg/L and 0.032 to 95 µg/L, respectively. The highest PFOA and PFOS concentrations were detected at wells that are screened in the overburden. The PFOA concentrations were above the PHA (0.4 µg/L) in 10 of the 11 overburden wells and 5 of 7 bedrock wells. The UNDS 00536 -PL- PFOS concentrations were above the PHA (0.2 µg/L) at all 11 overburden wells and 5 of 7 CBI •

bedrock wells. The GWTS effluent was below the PHA for both PFOA and PFOS.

February 2016 For the September 2013 sampling event, 21 locations were sampled including 12 overburden • wells, 7 bedrock wells, the GWTS effluent, and Watering Spring. Again, both PFOA and Revision 0 • PFOS were detected in all samples collected. The PFOA and PFOS concentrations were slightly lower than the June 2013 values. The PFOA and PFOS concentrations ranged from Draft Final • 0.0021 to 72 µg/L and 0.015 to 42 µg/L, respectively. The highest PFOA and PFOS concentrations were again also detected in overburden wells—563 and 5133 µg/L, respectively. PFOA concentrations were above the PHA (0.4 µg/L) in 9 of 12 overburden Task Order No. 0010 wells, 5 of 7 bedrock wells, and Watering Spring. PFOS concentrations were above the PHA (0.2 µg/L) at 9 of 12 overburden wells, 6 of 7 bedrock wells, and Watering Spring. The GWTS effluent was again below the PHAs for PFOA and PFOS. Groundwater data and sample locations are shown on Figure 3. Contract FA8903 No. 8580 , - 09 -D- 2.2 Residential Well PFC Sampling A separate effort is ongoing to determine the presence of PFCs in residential wells within an approximate 1-mile radius of the boundaries of the former Pease AFB, including Newington and Greenland, New Hampshire, by another AFCEC contractor. To date, a total of 730 properties are within the inventory area; however, interviews with the property owners indicated that only 37 of the properties utilized private wells for drinking water. It should be noted that three properties share one well; therefore, there were a total of 35 wells that were sampled as part of the original sampling program. Initial data indicate that PFCs are present in some of these wells and PFOS is above the current PHA (0.2 µg/L) in one residential well, located to the northeast approximately 2,800 feet from Site 8 (Figure 3).

2-2 2.0 SITE BACKGROUND

CB&I FEDERAL SERVICES LLC

Currently, 33 of the 35 wells are included in the residential drinking water long-term PERFORMANCE MONITORI monitoring (LTM) program for PFCs, since two of the well owners declined to be included. The residential drinking water LTM program is separate from the scope of work included herein, which focuses on the PFCs in groundwater near the Site 8 GMZ area.

2.3 Hydraulic Characteristics NG PLAN FOR Figures 4 and 5 show the general groundwater flow patterns at Site 8 in the overburden and bedrock, respectively during times of high water table. A bedrock trough runs roughly PERFLUORINATED COMPO PERFLUORINATED southwest to northeast at Site 8, creating a groundwater divide. As a result, overburden flow runs along the trough to the northeast. Local patterns are modified by the two extraction well arrays. The groundwater flow in bedrock also trends along the bedrock trough from southwest to northwest, similar to groundwater in the overburden.

UNDS 00536 -PL- Table 1 summarizes the construction details for monitoring wells that are used for the CBI •

monitoring program for PFCs at Site 8. February 2016 • 2.4 Groundwater Extraction Approach The approach for extracting groundwater for the treatment of PFCs consists of the existing Revision 0 • GWTS that has been in operation at Site 8 since 1995. The Site 8 treatment system also Draft Final

• includes an SVE system and an air sparge component; however, these systems were shut off

in 2012 due to lack of product recovery and only the GWTS is in operation. The GWTS consists of six extraction wells and five recharge trenches, and the groundwater is primarily

Task Order No. 0010 treated using carbon adsorption. The extraction wells intercept and hydraulically contain groundwater originating from the former burn pit area. Five of the six extraction wells (08- 5143 through 08-5147) form an array in the middle of the site, and represent less than 20 percent of the total extracted flow. The sixth extraction well (08-5149) represents the majority of the extracted groundwater (greater than 80 percent) and is located in the bedrock Contract FA8903 No. 8580 , - 09 -D- trough downgradient of the other five extraction wells (Figure 2). Historically, treated groundwater has been discharged to the subsurface via five recharge trenches. Four of the five recharge trenches (Trenches A through D) are located along the south and southwestern edge of Site 8 and were placed offline in July 2002 to better dewater the source area. The sixth recharge trench (Trench E) is located off site. Currently, the GWTS effluent is discharged to Groundwater Recharge Trenches A and B instead.

Process sampling in the GWTS is covered in detail in the Site 8 Operation and Maintenance Plan for the Treatment of Perfluorinated Compounds in Groundwater (CB&I, 2015).

CB&I FEDERAL SERVICES LLC PERFORMANCE MONITORI 3.0 SITE 8 MONITORING ACTIVITIES

The PFC monitoring activities for Site 8 will be conducted for both groundwater and surface water. In addition to water quality monitoring that will be conducted at all of the

groundwater and surface water locations, groundwater monitoring will also include the NG PLANPERFLUOR FOR collection of water level measurements. The monitoring wells and surface water sampling locations to be monitored are provided in Table 1 and are presented on Figure 6. Additional details regarding the groundwater system monitoring at Site 8 are discussed below.

3.1 Groundwater Quality Monitoring COMPOUNDS INATED The groundwater quality monitoring program at Site 8 includes sampling of 21 groundwater

wells (Table 1). The samples will be submitted to ALS Environmental (ALS) located in

00536 -PL- Kelso, Washington, and will be analyzed for the complete list of 23 PFCs using high CBI • performance liquid chromatography/tandem mass spectrometry per their internal standard

operating procedure (SOP) Perfluorinated Compounds by High Performance Liquid February 2016

• Chromatography/Tandem Mass Spectroscopy (HPLC/MS/MS). ALS is currently an accredited laboratory under the U.S. Department of Defense Environmental Laboratory Revision 0 • Accreditation Program for the analysis of PFCs, and their approved SOP is provided in ft Final

Dra Appendix A. The total number of PFCs to be analyzed may be modified in the future to • reflect any approved basewide PFC program changes. The complete list of PFCs to be sampled, along with their reporting limits, are presented in Table 2.

Task Order No. 0010 Sampling procedures for groundwater quality monitoring will follow the AMEC Foster Wheeler SOPs for PFCs presented in Appendix B. This SOP will formally be added to the Pease Installation-Wide Quality Program Plan (IWQPP) in 2015/2016 in the form of an IWQPP addendum. Contract FA8903 No. 8580 , - 09 -D- Performance monitoring for PFCs at Site 8 includes groundwater sampling in the spring, summer, and fall to track the progress and to monitor the off-site migration of contaminated groundwater. Winter samples are not proposed due to access issues typically related to freezing and snow conditions.

3.2 Groundwater Level Monitoring Groundwater level measurements will be collected on a quarterly basis at the monitoring well locations identified in Table 1. Similar to groundwater quality monitoring, winter groundwater level monitoring events are not proposed due to access issues typically related to freezing and snow conditions. The water level measurements collected as part of the monitoring activities described herein will be incorporated along with the groundwater level measurements from the routine Site 8 ROD–based LTM activities (MWH Americas, Inc.

FIELD SAMPLING PROTOCOLS TO AVOID CROSS-CONTAMINATION AT PERFLUORINATED COMPOUNDS (PFCs) SITES SOP AMEC-01 (PFCs)

1.0 PURPOSE The purpose of this Standard Operating Procedure (SOP) is to describe the procedures/considerations when collecting soil, sediment, surface water, and groundwater samples at potential PFC release sites. Sampling specific SOPs should also be reviewed prior to conducting field sampling activities at PFC sites. The information contained within this SOP is included within sampling specific SOPs as applicable.

2.0 SCOPE This procedure applies to all AMEC personnel and subcontractors who collect or otherwise handle samples of soil, sediment, surface water, and groundwater for analysis of PFCs. This SOP should be reviewed by all on-site personnel prior to implementation of field activities.

3.0 REFERENCES Transport Canada, 2013. Perfluorochemical (PFC) Field Sampling Protocol. May. Delta Consultants, 2010. Report of Investigation Activities at Select Firefighting Foam Training Areas and Foam Discharge Sites in Minnesota. February. MPCA, 2008. Closed Landfill Program Sampling Protocol for Monitoring Wells. October.

4.0 GENERAL Given the low detection limits associated with PFC analysis and the many potential sources of trace levels of PFCs, field personnel are advised to act on the side of caution by strictly following these protocols, frequently replacing nitrile gloves, and rinsing field equipment to help mitigate the potential for false detections of PFCs. Specific items related to field sampling are discussed below.

5.0 RESPONSIBILITIES Project Manager The Project Manager shall provide the Quality Project Plan (QPP) and installation-specific work plan, which shall include the sampling requirements for each site. The Project Manager will report deviations to this procedure to the Quality Control (QC) Manager and the AFCEC Contracting Office Representative (COR).

Rev. 1 1 Date: 07/21/2014 B-1 Field Manager The Field Manager shall ensure that samples are collected in accordance with the QPP, installation-specific work plans, and applicable SOPs. The Field Manager shall also be required to make rational and justifiable decisions when deviations from these procedures are necessary because of field conditions or unforeseen issues and report the deviations to the Project Manager.

Quality Control Manager The QC Manager will be responsible for conducting field audits during sampling activities. During these audits, the QC Manager will ensure that field crews are adhering to the QPP including sampling techniques, field documentation, sample packaging, chain of custody documentation procedures, and equipment calibration. Field Personnel Field personnel assigned to sampling activities are responsible for completing their tasks according to specifications outlined in the QPP, installation-specific work plans, applicable SOPs, and other appropriate procedures. Field personnel are responsible for reporting deviations from procedures to the Field Manager.

6.0 PROCEDURES/CONSIDERATIONS The following are procedures/considerations to be made during field activities at potential PFC release sites. A summary of the prohibited and acceptable items for PFC sites is included in Table 1. A checklist, provided as Attachment 1, shall be used daily prior to the commencement of fieldwork to ensure the field team is in compliance with this protocol. Field Equipment • Do not use Teflon®-containing materials (e.g., Teflon® tubing, bailers, tape, plumbing paste, or other Teflon® materials) since Teflon® contains fluorinated compounds. • Do not use low-density polyethylene (LDPE) materials during sampling. High-density polyethylene (HDPE) and silicon materials are acceptable. • AMEC will use peristaltic pumps for groundwater sample collection at depths shallower than 25 feet. AMEC will use ProActive SS Pumps with PVC leads or Geotech SS Geosub pumps for groundwater sample collection at depths greater than 25 feet. These pumps are stainless steel and will minimize introductions of PFCs. • When using liners to collect soil samples during direct-push technology (DPT) or conventional drilling methodologies, acetate liners are to be used.

Rev. 1 2 Date: 07/21/2014 B-2 • To avoid plastic coating or glue materials, do not use waterproof field books. Field reports will be documented on loose paper on masonite or aluminum clipboards (i.e. plastic clipboards, binders, or spiral hard cover notebooks are not acceptable) using a pen or pencil. Sharpies®/markers may be used. • Post-It Notes are not allowed on project sites. • Do not use markers other than Sharpies®markers. Pens will be used when documenting field activities in the field log and on field forms as well as labeling sample containers and preparing the Chain of Custody. • Do not use chemical (blue) ice packs during the sampling program. This includes the use of ice packs for the storage of food and/or samples. Field Clothing and Personal Protective Equipment • Do not wear synthetic water resistant, waterproof, or stain-treated clothing during the field program. Field clothing to be worn on-site should be restricted to natural fibers (preferably cotton) and not synthetic. Field clothing should be laundered avoiding the use of fabric softener. Preferably, field gear should be cotton construction and well laundered (a minimum of 6 times from time of purchase). New cotton clothing may contain PFC related treatments. Do not use new clothing while sampling or sample handling. • Do not wear clothing or boots containing Gore-Tex™ during the sampling program as it consists of a PFC membrane. • All safety footwear will consist of steel-toed boots made with polyurethane and polyvinyl chloride (PVC). • Do not wear Tyvek® clothing on-site since it contains fluorinated compounds. • Disposable nitrile gloves must be worn at all times. Further, a new pair of nitrile gloves shall be donned prior to the following activities at each sample location: - Decontamination of re-usable sampling equipment; - Prior to contact with sample bottles or water containers; - Insertion of anything into the well (e.g. HDPE tubing, HydraSleeve bailer, etc.); - Insertion of silicon tubing into the peristaltic pump; - Completion of monitor well purging, prior to sample collection; - Handling of any quality assurance/quality control samples including field blanks and equipment blanks; and, - After the handling of any non-dedicated sampling equipment, contact with non- decontaminated surfaces, or when judged necessary by field personnel.

Rev. 1 3 Date: 07/21/2014 B-3 Sample Containers • Different laboratories may supply sample collection containers of varying sizes dependant on the type of media to be sampled (e.g., soil, groundwater, etc.). However, all samples should be collected in polypropylene or HDPE bottles fitted with an unlined (no Teflon®), polypropylene HDPE screw cap. • Container labels will be completed using pen after the caps have been placed back on each bottle. • Glass containers should also be avoided due to potential loss of analyte through adsorption. Wet Weather • Field sampling occurring during wet weather (e.g., rainfall and snowfall) should be conducted while wearing appropriate clothing that will not pose a risk for cross- contamination. Teams will avoid synthetic gear that has been treated with water- repellant finishes containing PFCs. Use rain gear made from polyurethane and wax- coated materials. • Teams should consider the use of a gazebo tent, which can be erected overtop of the sample location and provide shelter from the rain. It should be noted that the canopy material is likely a treated surface and should be treated as such; therefore, gloves should be worn when moving the tent, changed immediately afterwards and further contact with the tent should be avoided until all sampling activities have been finished and the team is ready to move on to the next sample location. Equipment Decontamination Field sampling equipment, including oil/water interface meters and water level indicators, that are utilized at each sample location will require cleaning between uses. Alconox® and Liquinox® soap is acceptable for use since the Material Safety Data Sheets do not list fluoro- surfactants as an ingredient. However, Decon 90 will not be used during decontamination activities. Water used for the final rinse during decontamination of sampling equipment will be laboratory certified “PFC-free” water. For larger equipment (e.g., drill rigs), decontamination will be conducted with potable water using a high-pressure washer and then rinsed using potable water.

Rev. 1 4 Date: 07/21/2014 B-4 Personnel Hygiene • Field personnel will not use cosmetics, moisturizers, hand cream, or other related products as part of their personal cleaning/showering routine on the morning of a sampling event, as these products may contain surfactants and represent a potential source of PFCs. • Many manufactured sunblock and insect repellants contain PFCs and should not be brought or used on-site. Sunblock and insect repellants that are used on-site should consist of 100% natural ingredients. A list of acceptable sunscreens and insect repellents are listed in Table 1. • For washroom breaks, field personnel will leave the exclusion zone and then remove gloves and overalls. Field personnel should wash as normal with extra time for rinsing with water after soap use. When finished washing, the use of a mechanical dryer is preferred and the use of paper towel for drying is to be avoided (if possible). Food Considerations • No food or drink shall be brought on-site, with the exception of bottled water and hydration drinks (i.e., Gatorade® and Powerade®), which will only be allowed to be brought and consumed within the staging area. Visitors • Visitors to the site are asked to remain outside of the exclusion zone during sampling activities.
