WARREN, MAINE

SECTION 1 | EXECUTIVE SUMMARY

CES, Inc. (CES) completed a Phase II Environmental Site Assessment (ESA) at the Steamship Navigation property located at 2287 Camden Road in Warren, Maine (Site). Based on the results of soil and porewater sampling performed by the Maine Department of Environmental Protection (MDEP) in May 2018, it was determined that further investigation of the Site was necessary for the assessment of per- and polyfluoroalkyl substances (PFAS). In August and September 2018, CES performed the following work on behalf of the MDEP as part of the Phase II ESA for the Site:

◆ Performed ground-penetrating radar (GPR) surveying to determine depths to bedrock in areas of interest within the Site.

◆ Advanced 10 soil borings via direct push technology (DPT) at 10 locations.

◆ Collected a total of 16 soil samples, and one duplicate, from soil borings advanced at the Site.

◆ Installed and developed temporary monitoring wells at two DPT locations.

◆ Sampled overburden groundwater at one temporary microwell location to characterize groundwater quality.

◆ Completed multi-increment sampling (MIS) in the vicinity of the three waste types at the Site, including baled fiber material, papermill short paper fiber, and covered polyester fiber material.

◆ Performed x-ray fluorescence (XRF) scanning for lead at locations adjacent to Site buildings; and,

◆ Collected seven soil samples for RCRA 8 metals analysis in areas screened using the XRF.

GPR data collection did not result in any anomalous conditions within surveyed portions of the Site, with bedrock ranging between 0 and 2.5 ft below ground surface (BGS) (Table 1). Depth to bedrock, as interpreted in the field, generally correlated with encountered depths to bedrock from DPT soil boring locations; however, borings located to the southwest of the Site (DPT-01 and DPT-02) varied in depths to bedrock from those interpreted from GPR records. This is believed to be due to variations in bedrock depths along the west and southwest of the Site and visual evidence for the use of baled waste material under access roads. Exposed bedrock was located to the east of the roadway along GPR Transect No. 2 with encountered depths to bedrock in DPT-01 and DPT-02 (located west of GPR Transect No. 2) being 8 ft BGS and 13.9 ft BGS, respectively.


A total of 10 soil borings were completed using DPT resulting in a total of 16 soil samples being submitted for PFAS analysis. Each boring was completed to refusal, which was encountered at depths ranging from ground surface (DPT-04) to 14 feet BGS (DPT-02). Detected concentrations of perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluorobutanesulfonic acid (PFBS) were below the leaching to groundwater criteria (Table 2) as contained in the MDEP Maine Remedial Action Guidelines (RAGs) for Sites Contaminated with Hazardous Substances (MDEP, 2018). Two temporary microwells were installed within DPT borings where water was encountered; however, only one microwell (TW-2) contained sufficient water for sampling following development. A groundwater sample from TW-2 was submitted to Vista Analytical Laboratory (Vista) for analysis of PFAS. Analytical results indicate that PFOS and PFOA were detected at concentrations above the Maine Center for Disease Control (MeCDC) Maximum Exposure Guideline (MEG) of 70 nanograms per liter (ng/L). PFOS and PFOA were reported at a concentration of 88.0 ng/L and 88.6 ng/L, respectively. These results are consistent with the results obtained by MDEP in a porewater sample (PW-1) collected 600 feet south of TW-2 in May 2018. Composite soil samples from MIS activities were submitted for analysis of PFAS and included a sample and associated replicate from a 0-10 ft distance from the base of waste (Zone A) and a sample located 10-20 ft from the base of waste material (Zone B) as illustrated in Figure 2 through Figure 7. Samples from Zone A (primary and/or replicate sample) and Zone B associated with baled material and short paper fiber detected PFOS at a concentration above the RAG; however, detected concentrations of PFOA and PFBS were below applicable RAGs. PFAS concentrations in Covered Waste (CW) samples were reported as below the detection limit (DL) for the three PFAS compounds with applicable soil RAGs (PFOA, PFOS, and PFBS). Soil samples collected from the indoor firing range (IFR) included a sample from each of the four openings to the exterior, as illustrated on Figure 5. Three of the four analytical samples collected near the IFR were above the construction worker RAG for lead (450 mg/kg). A total of 36 locations were field-screened via XRF near the mobile home trailer, having been previously used in processing of photographic film, with two soil samples subsequently submitted to Alpha for lead analysis. Neither sample collected from the areas surrounding the trailer exceeded the RAG for lead. Screening locations in the vicinity of the spent ammunition lead pile were positioned, due to exposed bedrock, to account for the flow of precipitation as surface water towards and across the visible spent lead fragments. Lead was reported in this area at a concentration of 9,760 mg/kg, which is approximately 20 times the current construction worker RAG. SECTION 2 | SCOPE OF WORK CES performed the following Scope of Work as outlined in the MDEP Request for Bids #90 and CES’ bid submittal dated July 27, 2018. The Phase II ESA activities included:

◆ Site clearance for underground utilities;

◆ A survey of accessible portions of the Site using Ground Penetrating Radar (GPR);

◆ Clearance of soil boring locations of waste using an excavator;

◆ Advancing 10 soil borings beneath waste piles at locations identified by MDEP using direct push technology;

◆ Collection of 16 soil samples from the 10 direct push soil borings;


◆ Completion of two soil boring locations as temporary microwells and subsequent groundwater sampling;

◆ Collection of nine composite surface samples using Multi-Increment Sampling Methodology;

◆ X-Ray Fluoroscope (XRF) screening of surficial soils in the vicinity of the Indoor Firing Range, former photo processing trailer, and pile of spend lead ammunition; and

◆ Collection of seven surface soil samples based on XRF screening results and submittal for RCRA 8 Metals analysis.

Results of these activities are presented below with details provided on Site background and history, methodology used during the investigation, and discussion of results for analyzed soil and groundwater samples. SECTION 3 | LOCATION AND BACKGROUND INFORMATION 3.1 General Description

The Steamship Navigation property consists of approximately 71.40 acres located at 2287 Camden Road in Warren, Maine and is developed with three buildings (Figure 1). The Warren Tax Assessor’s Office currently identifies the Site as Lot 38 on Town of Warren Tax Map R-11 with the Knox County Registry of Deeds containing a legal description of the Site recorded in Book 2189 Page 156. The Site is currently developed with three structures, including a single-story wood-framed building with offices and indoor firing range on a concrete slab, a single-story concrete block garage on a concrete slab, and a metal-sided mobile home trailer. The ground surface at the Site slopes gently to the southwest with several areas having been regraded to construct and maintain gravel roadways. Most areas have not been maintained since the facility ceased operations; however, based on spent ammunition casings and presence of vehicles entering and exiting the Site during the investigation, some areas to the south and east appear to be currently used as a firing range. Groundcover consists primarily of landscaped green areas, gravel roadways, bales of formed fiber, exposed bedrock outcrops, and sparsely vegetated soil. The subject property is accessed from the north via an entrance from Camden Road with gravel roadways extending to the southeast and southwest portions of the Site as illustrated on Figure 1.

3.2 Environmental Setting, Geology, and Hydrogeology The Bedrock Geology Map of Maine (Osberg et al, 1985) describes bedrock underlying the Site as calcareous sandstone; interbedded sandstone, and impure limestone. CES observed bedrock outcroppings at several locations on the Site during investigation activities with the depth to bedrock, as determined through direct push sampling, varying between 0 and 14 feet BGS. The Surficial Geologic Map of Maine (Thompson et al, 1997) indicates that glaciomarine deposits (silt, clay, sand and minor amounts of gravel) underlie the Site and according to the Significant Sand and Gravel Aquifer Map of the West Rockport Quadrangle, Maine (Weddle, 2009), the Site is not underlain by a mapped significant sand or gravel aquifer. Based upon the USGS topographical map for the Site and surrounding area, groundwater flow is inferred to be generally south toward the Oyster River.


3.3 Site History Based upon observations made during the Site visit and information supplied by the MDEP from previously completed investigations, it has been determined that within the last 30 years, the Site has been occupied by a retail firearms store. This facility included both an indoor firing range (IFR) and outdoor firing range (OFR). In addition, a photographic laboratory was in operation for a short period of time on the Site during this time period. According to the results of previous Phase I Environmental Site Assessments (ESAs) conducted at the Site, the firing ranges began operation sometime during the 1970s. As a portion of its use as a firearm sales business (RD Outfitters), two firing ranges were developed on the Site. The IFR was located within the main building. The OFR was located east of the main building within a raised berm area and was originally designed as a 600-meter shooting range but was later converted to a shorter (approximately 100-meter) range. A small room within the main building appears to have been used for the manufacture of small quantities of ammunition, based upon the presence of tools and supplies associated with this practice, including several lead ingots. To lessen the sound of the shooting range and to absorb ammunition fragments, the current owner began accepting waste material from Gates Formed-Fiber in Auburn, Maine in 1997 to create berms with this material. The MDEP approved the use of fiber material in a Solid Waste Beneficial Reuse Permit issued in 1997. The material consists of a non-woven fabric used to manufacture automobile trunk liners. Currently, approximately 25% of the Site is covered by berms of this waste fiber material. A Phase I ESA completed by Summit Environmental Consultants, Inc. (Summit) in 2007 estimated that approximately 254,000 square feet (SF) of fiber is present at the Site. The berms are in various stages of completion, ranging from uncovered to completely covered and vegetated. It is unknown if the berms, used as bullet stops, were ever cleaned to remove spent bullets and associated fragments. The MDEP did require that spent bullets and associated fragments be collected annually as a condition of the 1997 MDEP Solid Waste Beneficial Reuse Permit. According to previous Site investigations, a small room within the main building, which was used to make ammunition, was also used, at one time, as a photographic laboratory for the development of school photographs. MDEP records indicate that approximately 20 rolls of black and white film were processed in this laboratory on a yearly basis with silver recovery done on the property. Documentation of this and the removal of the actual silver recovery units at the end of the laboratory’s usage could not be verified during the previous investigations.

3.4 Previous Investigations Summit Environmental Phase I ESA: Summit completed a Phase I ESA for the Site dated July 27, 2007. The following Recognized Environmental Conditions (RECs), Historical Recognized Environmental Conditions and/or De Minimis Conditions were identified at the Site:

◆ Fiber materials from Gates Formed Fiber were brought to Site for use in the construction of sound reduction and bullet stop berms. Approximately 254,000 square feet of fiber was present on the property. The presence of this material was currently in violation with the conditions of the MDEP’s Solid Waste License #S-21758-WL-A-N.


◆ Photographic chemicals were disposed to the on-Site septic tank during the operation of a photographic laboratory on the Site.

◆ An IFR was operated inside of the Office Building. Contamination associated with this usage, including lead dust and bullet fragments may be present within the IFR.

◆ The operation of OFRs operated on-Site may have resulted in the presence of lead contaminated soils and bullet fragments within the range area and in the bullet stop berms.

◆ Ammunition manufacturing within the room of the Office Building may have resulted in the presence of lead contamination, associated with the melting of lead ingots, on the surfaces within this room.

Summit made the following recommendations based on the results of the Phase I ESA:

◆ Perform a Phase II ESA, including a subsurface investigation of soil including areas within the OFR at the Site as well as laboratory analysis of groundwater samples collected from on-site monitoring wells to determine if former Site activities (firing range and photo lab) have impacted Site soil and groundwater.

◆ Due to on-site usage of photochemicals, lead, and solvent-based cleaners, a water sample should be collected from the water supply well at the Site for laboratory analysis of volatile organic compounds (VOCs), semivolatile organic compounds (SVOCs), total Resource Conservation and Recovery Act (RCRA) metals.

◆ Prior to reuse of the Office Building, lead sampling should be performed to determine if it is suitable for habitation.

◆ Submit a plan for the finalization of the Gates fiber berms to the MEDEP’s Solid Waste Bureau to address the violations incurred by Steamship Navigation.

◆ Summit recommends that the future property owner apply to the MEDEP Voluntary Response Action Program (VRAP).

Summit Environmental Phase II ESA: Summit completed a Phase II ESA for the Site dated October 29, 2007. The purpose of the Phase II ESA was to characterize surface and subsurface soil at the Site to determine if these soils have been impacted by historical use of the Site as a firing range and photographic laboratory. Summit performed the following investigations as part of the Phase II ESA: ◆ Advancement of soil borings in 12 locations and installation and development of two

monitoring wells to characterize groundwater at the Site.

◆ Collection of groundwater samples from each of the two temporary monitoring wells installed at the Site.

◆ Collection of a sample from the on-Site drinking water well.

◆ Collection of seventeen lead wipe samples to determine whether impacts were present within the Office Building.

◆ Collection of one soil sample from one of the twelve soil borings advanced at the Site.

◆ Collection of six surficial soil samples at the Site.

◆ Screening of soil samples collected on-Site with an X-Ray Fluorescence (XRF) device to determine total metals levels.


Elevated concentrations of lead, above the MDEP RAGs for the Outdoor/Construction Worker, were identified in four of the seven soil samples submitted for laboratory analysis. Soil samples with elevated lead concentrations were all collected from the area surrounding the IFR. In addition, arsenic concentrations above the Outdoor/Construction Worker RAG were identified in three of the seven soil samples submitted for analysis. Groundwater analytical results from the two temporary monitoring wells and the on-site water supply well did not report concentrations of any metals, Volatile Organic Compounds (VOCs) or Semi-Volatile Organic Compounds (SVOCs) at concentrations above the MEGs. Summit made the following recommendations based on the results of the Phase II ESA:

◆ Apply to the MDEP Voluntary Response Action Program (VRAP) to obtain a release of liability for the property.

◆ If the main building is to be reused, a thorough cleaning/decontamination will be required for the entire building to remove lead debris and lead dust to allow for occupancy.

◆ If the main building is to be demolished, lead fragments should be removed from the backstop and a sample of the concrete backstop within the indoor firing range should be collected to determine if leachable lead exists within it.

◆ Encapsulate or remove and properly dispose of lead-impacted soils above the MDEP RAGs for Adult Workers.

◆ Prior to renovation/demolition of the buildings, an asbestos-containing materials (ACM) survey should be performed.

◆ Hazardous materials (paints, lead ingot, spent shells, live shells), Universal Waste, and petroleum products should be removed from the Site and disposed of properly.

◆ Although the fiber bales do not present a contaminant risk, they present a

regulatory challenge, as well as a potential fire hazard. Therefore, the bales should

be removed or covered as initially permitted by the MDEP Solid Waste Division.

Beacon Environmental Consultants Phase I ESA: Beacon Environmental Consultants, LLC (Beacon) completed a Phase I ESA for the Site dated June 5, 2018. The following RECs were identified during completion of the Phase I ESA:

◆ The property was listed in 2007 as a Solid Waste Facility with licenses held by Steamship Navigation and Cascade Fiber;

◆ Past usage of the property as a firing range, photographic lab, and solid waste dumping of fiber bales;

◆ Past environmental reports indicated environmental issues with the property;

◆ Lead dust and small quantities of hazardous substances are present within the Site structure;

◆ Significant lead dust and bullet fragments are present within the Site structure based on past sampling and analysis. Additional sampling should be performed to determine disposal options.

◆ A sump is located within the IFR. No pump was present, and the discharge of this sump is not known;


◆ Significant solid waste dumping of fiber bales has occurred on the property. Additionally, a landfill of these bales was established to the northeast of the Site structures in the late 1990’s; and

◆ Distressed vegetation was observed in areas of bales of fiber. The following data gaps were identified by Beacon during completion of the Phase I ESA:

◆ Location/presence of a septic leach field associated with the septic tank is unknown;

◆ Due to the unsafe nature of the roof of the garage, this structure was not entered; and

◆ Dates of the photographic laboratory's operations on the Site could not be specifically identified.

Beacon made the following recommendations based on the results of the Phase I ESA: ◆ A Phase II ESA should be completed on the property to determine the presence of

ACM, LBP, lead concentrations within the firing (including the backstop), identification of the location/presence of a septic leach field and whether impacts are present within it, and additional soil samples to determine potential impacts from past usage of the property.

◆ A plan should be developed to complete the covering of the fiber bales or their removal to comply with past MDEP Notices of Violations (NOVs).

Maine Department of Environmental Protection PFAS Investigation On May 10 and 11, 2018, the MDEP collected soil, pore water, and drinking water samples at the Site for Per- and Polyfluoroalkyl Substances (PFAS) analysis as part of ongoing department investigation of potential PFAS Sites in the State of Maine. The investigation included the collection of 13 soil samples, six pore water samples, and one water sample from the on-site drinking water well. Results of the investigation identified four soil samples and four pore water samples containing PFAS in exceedance of the 2018 MDEP RAGs. In addition to the collection of analytical samples, a borehole geophysical survey was performed in the on-site well by Northeast Geophysical Services, Inc. (NGS) on May 10, 2018. The well is located immediately adjacent to the west side of the former retail business structure and was found to be 102 ft in depth with approximately 20 ft of overburden casing installed. The depth to water was measured at 5.36 ft below the top of casing (TOC) at the time of the survey. The well was logged for fluid temperature, fluid resistivity, borehole caliper, optical and acoustic televiewer, and heat pulse flowmeter. Results indicated a likely transmissive zone from 33 to 35 ft below TOC with a possible transmissive zone from 91 to 94 ft below TOC. Information from the borehole caliper and heat pulse data under pumping conditions indicated that the shallow interval (33 to 35 ft below TOC) was most likely the interval with the greatest contribution of water to the well.


SECTION 4 | FIELD SAMPLING PROGRAM 4.1 Utility Clearance and Surface Geophysical Survey

CES completed a DigSafe non-member utility notification and utility marking for proposed drilling locations as selected by MDEP on August 16, 2018 during a Site meeting between Chris Buckman of CES and Richard Currie and Sean Dougherty of the MDEP. Locations were selected based on waste type (e.g. baled material, short paper fiber, covered material), access, and location relative to previously collected soil, groundwater, and porewater samples. In addition to DigSafe notification and utility markout, CES performed ground-penetrating radar (GPR) surveying over accessible portions of the Site to determine the approximate depth to bedrock. Due to the requirements of the GPR antenna to remain in contact with the ground surface to ensure accurate profile information, CES defined “accessible” as areas of existing roadways and driveways that did not require preparation prior to data collection. These areas included a total of approximately 3,360 lineal feet of profile and are identified accordingly on Figure 1. Depths to bedrock were interpreted from collected profile data with corresponding coordinates and depths below ground surface (bgs) located in Table 1.

Based on tests performed in the field between a 270 MHz and a 400 MHz antenna, it was determined that a 400 MHz GPR antenna provided the requisite depth of signal penetration and desired resolution to meet the objective. The test was performed in an area of exposed bedrock located east of the Site buildings and within the center of the outdoor firing range berm. It was interpreted that the depth to bedrock varied between 0 feet BGS and 5 ft BGS, with depths confirmed with depths to refusal encountered during the direct push sampling investigation.

4.2 Direct Push Soil Borings

On August 20, 2018, Michael Deyling with CES mobilized to the Site to clear boring locations of waste material using an excavator under the supervision of Richard Currie with the MDEP. MDEP personnel directed Mr. Deyling to clear waste from 10 predetermined locations at the Site, as shown on the Site Plan (Figure 1), to allow access by the direct push rig to underlying soil. These locations were selected to include each type of waste material present at the Site. On August 23, 2018, CES mobilized to the Site to perform direct push soil sampling activities. CES advanced a total of ten soil borings utilizing Geoprobe® direct-push equipment. Soil borings were advanced at the following locations:

◆ Five borings below exposed baled material (BM) in two areas (DPT-01, DPT-02, DPT-03, DPT-04, and DPT-07);

◆ Two borings below covered Short Paper Fiber (SPF) material (DPT-05 and DPT-06); and

◆ Three borings below the covered material (CM) area (DPT-08, DPT-09, and DPT-10).


Each boring was completed to refusal, which was encountered at depths ranging from ground surface (DPT-04) to 14 feet BGS (DPT-02). Soil samples were collected in acetate sleeves in four-foot intervals and characterized in the field. Typical subsurface soils encountered were classified as sandy to rocky fill in each of the soil boring locations with several locations terminating on waste that included short paper fiber or formed fiber upholstery material. Boring locations are illustrated on the Site Plan (Figure 1) with completed soil boring logs included as Appendix A. Soil samples were visually inspected for the presence of waste material, staining or other evidence of potential environmental impacts. A total of 16 soil samples from the 10 soil borings were selected for laboratory analysis based on field observations and/or location with an additional two duplicate samples collected for submittal to Vista. All collected samples were submitted to Vista for laboratory analysis for the presence of PFAS compounds using USEPA method 537M by isotope dilution. Results of the laboratory analysis are discussed in Section 6.2.

4.3 Monitoring Well Installation and Sampling On August 23, 2018, CES completed two of the direct push sample locations (DPT-02 and DPT-09) as one-inch temporary microwells TW-1 and TW-2, respectively. TW-1 was installed to a depth of approximately 12 ft BGS and was constructed with 10 feet of 0.010-inch slotted PVC well screen and five feet of PVC riser. A fine silica sand filter was installed to a depth of one ft BGS followed by a bentonite seal to ground surface. TW-2 was installed to a depth of approximately 7.9 feet BGS and was constructed with five feet of 0.010-inch slotted PVC well screen and five feet of PVC riser. A fine sand filter was installed to a depth of two feet BGS followed by a bentonite seal to ground surface. After installation, each temporary well was developed utilizing a peristaltic pump until purge water was visually clear. Following the initial development, groundwater did not appear to recharge at TW-1. CES returned to the Site on August 28, 2018 to sample the newly installed monitoring wells. Groundwater was not present in TW-1; therefore, the well was not sampled. Temporary well TW-2 was pumped dry after approximately 10 minutes of purging. The pump was stopped, and the well was allowed to recharge for approximately 20 minutes. CES collected a groundwater sample from TW-2 and submitted the sample to Vista for analysis of PFAS.

4.4 Multi-Increment Soil Sampling

On September 28 and 30, 2018, CES conducted surface soil sampling around three types of identified waste material, as selected by MDEP, using Incremental Sampling Methodology (ISM) in accordance with MDEP standard operating procedure (SOP) RWM-DR-015 Incremental Sample Methodology for Site Investigation and Risk Assessment. The three areas selected by MDEP were designated as Covered Waste (CW), Short Paper Fiber (SPF) and Baled Material (BM) based on the material within the pile being sampled.


Prior to mobilization, GIS software was used to divide the surface soil sampling areas into two zones, one from zero to 10 feet (inner zone) of the edge of the designated pile (Zone A) and the second between 10 and 20 feet (outer zone) from the edge of the designated pile (Zone B). Each zone was divided into a 30-cell grid and further divided into nine cells of equivalent area, which were assigned a number 1-9. A random number generator was used to select one of the nine sub-cells for sampling with a surface soil aliquot to be collected from the center of each designated cell. The GPS coordinates of each aliquot location were then stored in the GPS for use by field personnel. Replicate aliquots were collected six inches from the primary sample in Zone A. Replicate aliquots were not collected in Zone B. Figures 2 through 4 depict the locations of the sample aliquots collected by CES during this investigation. In total, approximately 80 percent of locations were able to be sampled within the baled material, 57 percent within the short paper fiber, and 100 percent within the covered material investigation areas. Upon field inspection, several of the pre-selected GPS locations were not able to be sampled due to waste material or other obstruction present in the location. Efforts were made to relocate the sample; however, there were several site-specific conditions that prevented repositioning. These conditions included, but were not limited to exposed bedrock, location in an area of comingled waste containing more than one type, and extensive limits of waste outside areas of sampling. The following changes were made to the aliquot locations based on conditions at the time of sampling: Baled Material:

◆ Samples BM-I-1, -02, and -30 were not collected as they were located on the gravel road. Movement of the samples to a representative area off the gravel drive would have resulted in a location within another sampling grid.

◆ Samples BM-I-27, -28 and -29 were located in areas of short paper fiber. BM-I-27 was moved to a location approximately five feet from the edge of the pile where waste material as not present. Locations BM-I-28 and -29 were not collected due to amount of SPF waste material present.

◆ Sample BM-I-08 was not collected as the location was determined to be under baled material.

◆ BM-O-28 and BM-O-29 were located in areas where SPF was present. BM-O-28 was moved to a location approximately 15 feet from the edge of the baled material where SPF was not present. Aliquot BM-O-29 was not collected as moving the location would put it in the road and outside of an area believed to be representative of the requisite conditions for sampling.

◆ BM-O-02 and BM-O-08 were not collected as they were located under waste material.

◆ Sample BM-O-11 was located on top of a bedrock outcrop and was not collected. Movement of the sample to a representative area off the bedrock outcrop would have resulted in a location within another sampling grid.

Short Paper Fiber:

◆ SPF-I-09 and -10 were moved approximately five feet from the edge of the waste pile into a location within Zone A.

◆ SPF-I-25, -27 through -30 and -1 through -8 were located within waste material and could not be relocated due to extensive waste present in the area.

◆ SPF-O-01 through -09, -20, -24, -29, and -30 were located in waste material and could not be moved due to extensive waste present in the area.


◆ SPF-O-10 was originally located in waste material and was moved approximately 15 ft from the interpreted edge of the waste pile into Zone B.

Covered Waste: ◆ CW-I-15, -16, -19, -20, -21. -22, -27, -28, and -29: Original locations were on a

slope of covered waste material. Locations were adjusted 5 feet beyond the toe of the slope into Zone A.

◆ CW-O-17, -18, -20. -21, and -22: Original locations were on a slope of covered waste material. Locations were adjusted 15 feet beyond the toe of the slope into Zone B.

Each sample aliquot was collected from zero to four inches (0-10 cm) BGS using a stainless-steel increment soil sampler which was decontaminated between sampling areas in accordance with MDEP RWM-DR-017 Equipment Decontamination Protocol, with provisions made to avoid use of any potential PFAS-containing materials. Collected aliquots were placed in a stainless-steel bowl and mixed until homogenous. A total of nine composite soil samples, comprised of six primary samples and three replicates, were submitted to Vista for analysis of PFAS by USEPA Method 537M and in accordance with MDEP SOP DR-012 Chain of Custody Protocol. In addition, field blanks were collected from the decontaminated stainless-steel samplers and bowls for PFAS analysis after the completion of surface soil sampling activities using laboratory-supplied PFAS-free water.

4.5 Surface Soil XRF Screening

On August 29, 2018, CES performed soil screening at the Site for metals using an Olympus Delta 4000 X-Ray Fluoroscope (XRF). Soil was screened in three areas including the Indoor Firing Range (IFR), a spent ammunition lead pile located to the west of the IFR between the building and wooded area, and a mobile home-style trailer believed to have been formerly used as a photography studio based on Phase I ESAs completed by others. The IFR screening locations were comprised of four individual openings to the structure and included two doors, a window, and wall-mounted exhaust fan. Surface soil samples (0-4”) were collected in Ziploc bags using a stainless-steel hand auger; however, efforts were made in the area surrounding the lead pile to sample at a depth of up to 8 inches, but shallow surface soils limited sampling depths. Following collection, each bag was screened using the XRF. Concentrations of lead and silver (Table 2) were recorded for samples around the trailer with remaining locations screened for lead only. A summary of the XRF screening data is included on Table 2 with sample location figures with screening values for lead presented in Figure 5 through Figure 7. After the completion of XRF screening, CES collected and submitted seven confirmation soil samples based on the highest screening levels observed. The collected samples included four from the IFR, two from the trailer, and one from the “lead pile”. Soil samples were sent to Alpha Analytical (Alpha) for laboratory analysis of eight Resource Conservation and Recovery Act (RCRA) metals. Surface soil analytical results are summarized in Section 6.3.


SECTION 5 | QUALITY ASSURANCE / QUALITY CONTROL Quality assurance and quality control (QA/QC) samples were collected in accordance with the July 27, 2018 proposal to MDEP. A total of one duplicate (DUP) per 10 samples and one matrix spike/matrix spike duplicate (MS/MSD) per 20 samples were proposed for sub-surface soil samples. There were no duplicates collected or submitted for groundwater or surface soil samples; however, replicate samples were collected as part of the multi-increment sampling effort as detailed below. All data, as qualified and presented in Table 3 through Table 5, are acceptable for use based on supplied laboratory case narratives (Appendix B). 5.1 Sub-Surface Soil

Based on the number of soil samples collected (16), a total of two duplicate samples were submitted for QA/QC purposes with reported concentrations between samples being within acceptable limits. An MS/MSD was performed on sample DPT-05 (5-6). As stated by Vista in their analysis of data for the submitted samples, the MS/MSD recoveries and relative percent differences (RPDs) were within the method acceptance criteria. A Method Blank and Ongoing Precision and Recovery (OPR) sample were extracted by Vista and analyzed with the preparation batch for the original samples and one for the re-extractables. There were no analytes detected in either Method Blank above one half the Limit of Quantification (LOQ). Recoveries for the OPR samples were within the method acceptance criteria for both OPRs.

5.2 Groundwater

Only one groundwater sample was collected, therefore no QA/QC samples were submitted for analysis, as per stated QA/QC sampling criteria. Dedicated equipment was used in the collection of the groundwater sample and did not require the collection of an equipment rinsate blank.

5.3 Multi-Increment Samples

A replicate sample was submitted for each inner zone (Zone A) sample collected (a total of 3 samples) with no replicate samples collected for the outer zone (Zone B), as dictated in the CES scope of work. In addition to replicate samples, equipment blank samples were submitted for the decontaminated stainless-steel sampler and bowl (two total) following the completion of surface soil sampling activities.

5.4 Surface Soil

As only seven surface soil samples were submitted for analysis, no QA/QC samples were collected as part of this investigation task. All samples were received by the laboratory in accordance with the chain of custody and no significant deviations were encountered during sample preparation or analysis.

SECTION 6 | EVALUATION AND PRESENTATION OF RESULTS 6.1 Subsurface Soils

A total of 16 subsurface soil samples were collected and submitted for laboratory analysis from 10 direct push subsurface locations as illustrated on Figure 1 with reported results for 26 PFAS compounds presented on Table 3. Samples were identified based on DPT boring location (DPT-XX) and depth interval in feet BGS (X-X). Subsurface soils were collected from each of the three waste material areas and included baled material (BM), short paper fiber (SPF), and covered material (CM). Soil results were compared to the MDEP RAGs for Sites Contaminated with Hazardous Substances (MDEP, 2018) for


PFOS, PFOA, and PFBS leaching to groundwater criteria. RAGs for PFOS, PFOA, and PFBS are 21 ng/g, 9.5 ng/g, and 7,100 ng/g respectively. Direct push sampling locations for the characterization of BM impacts to soil included DPT-01, -02, -03, -04, and -07. Locations DPT-01 and -02 were located adjacent to BM within the west/southwest portions of the Site with DPT-03 and -04 located near BM in the southeast. Location DPT-07 was in the center of the Site and positioned between CW material to the north and SPF to the south. Temporary microwell TW-01 was installed at DPT-02; however, did not contain enough water following development to obtain a groundwater sample. No samples were submitted from DPT-04 due to the presence of bedrock immediately below the ground surface. Analytical results for soil samples submitted for analysis of PFAS in the characterization of the BM area did not detect concentrations of PFOA, PFOS, or PFBS above applicable RAGs. Most samples resulted in remaining PFAS compounds at concentrations of not detected (ND) with values representative of being less than their respective detection limit (DL). DPT-01 (3-4), DPT-01 (7-8), DPT-01 (7-8) DUP, DPT-03 (3-4), and DPT-07 (0-1) contained levels of PFOS ranging from 2.66 ng/g at DPT-01 (7-8) DUP to 12.1 ng/g at DPT-07 (0-1). Detections of PFOS at DPT-01 were similar to those reported by the MDEP at soil borings SS-11 and SS-12 completed during their May 2018 investigation. PFOA was only detected in DPT-07 (0-1) with PFBS at ND levels within all samples submitted for soil characterization at BM locations. In general, analytical results for PFOS near BW locations were similar to those reported by the MDEP at nearby locations. For example, detections of PFOS at DPT-03 and DPT-07 were similar to MDEP results at locations SS-4 and SS-7, respectively.

Soil underlying CW material were sampled at direct push locations DPT-08, -09, and -10. A temporary microwell (TW-2) was installed in DPT-09 following advancement to refusal. A total of six samples were submitted for laboratory analysis from these three locations with results of ND for all PFAS compounds analyzed. Though DPT locations completed near CW piles were below detection limits, results as reported by the MDEP at SS-1 (May 2018) were at 1.9 ng/g combined for PFOS and PFOA. DPT-05 and DPT-06 were advanced along the northeast edge of the SPF waste material. A total of three samples (two primary and one duplicate) were submitted for analysis; however, these samples were from DPT-05 only due to the presence of subsurface SPF waste material at DPT-06. No detections of PFAS were present at DPT-05 (5-6) or DPT-05 (5-6) DUP; however, soil collected at DPT-05 (8-9) detected of both PFOS and PFOA. Though not above the applicable RAG, PFOS was detected at a level of 13.1 ng/g with PFOA at 1.04 ng/g, slightly above the DL at DPT-05 (8-9). In general, there was consistency between the values for PFOS and PFOA reported during this Phase II ESA and those reported by the MDEP during their May 2018 sampling investigation. Though some sampling locations were not identical between the two investigations, similarity in concentrations were present.

6.2 Groundwater

Following the installation and development of temporary microwells TW-1 and TW-2, an overburden groundwater sample was collected only from TW-2 due to insufficient water volume in TW-1 following development. The groundwater sample from TW-2 detected PFOS and PFOA at concentrations above the MeCDC MEG. The MEG is 70 ng/L for each compound or 70 ng/L combined when both PFOS and PFOA are found together.


PFOS and PFOA were reported at 88.0 ng/L and 88.6 ng/L, respectively. These results are consistent with those obtained by MDEP in a shallow porewater sample (PW-1) collected 600 feet south and downgradient of TW-2 during the May 2018 investigation. There were no additional groundwater samples collected as part of this Phase II ESA; however, groundwater was sampled by the MDEP from the on-site drinking water supply well located 380 feet west of TW-2 during the May 2018 investigation. Though PFOS (3.6 ng/L) and PFOA (13.4 ng/l) were both detected in the sample submitted to Vista, concentrations were below the MEG. Concentrations in the supply well are believed to be lower due to the source of water (overburden versus bedrock) and location up and cross gradient relative to stockpiled source material.

6.3 Multi-Increment Samples Multi-increment sampling (MIS) was completed at each of the three waste types (BM, SPF, and CW) within two zones (Zones A and B). Each inner zone (Zone A), located 0-10 ft from base of waste material, was comprised of a primary sample with a replicate. The outer zone (Zone B) was located 10-20 ft from base of waste material and did not include a corresponding replicate sample. This resulted in a total of nine samples being collected and submitted for analysis of PFAS. Results were compared to the MDEP Maine Remedial Action Guidelines (RAGs) for Sites Contaminated with Hazardous Substances (MDEP, 2018) for PFOS, PFOA, and perfluorobutanesulfonic acid (PFBS) leaching to groundwater criteria. The RAGs for PFOS, PFOA, and PFBS are 21 nanograms/grams (ng/g), 9.5 ng/g, and 7,100 ng/g, respectively. Baled material (BM) samples detected PFOS within both the inner Zone A (23.6 ng/g) and outer Zone B (21.5 ng/g) samples at concentrations above the RAG, with the Zone A replicate (17.7 ng/g) being slightly below the RAG. Of the three waste types investigated, SPF had the highest concentrations of PFAS, specifically PFOS and PFOA. The primary and replicate samples from Zone A of the SPF investigation area had concentrations above the RAG for PFOS at 61.9 ng/g and 67.6 ng/g, respectively, with the Zone B sample having a reported PFOS concentration of 42.4 ng/g, approximately twice the RAG of 21 ng/g. PFOA concentrations were below the applicable RAG within Zone A and Zone B with concentrations of PFBS being reported below the DL. No samples collected within Zone A or Zone B from the CW investigation area resulted in PFOA and PFBS at results above the DL. Detections of PFOS were reported at between 0.851 ng/g (Zone B) and 1.16 ng/g (Zone A). These results are believed to be typical with higher concentrations nearer the waste material and decreasing with increasing distance away from identified waste. Results for equipment blanks were below the detection limit for all PFAS compounds reported by Vista.

6.4 Surface Soil

A total of seven surface soil samples were submitted to Alpha for analysis of RCRA 8 metals based on XRF screening results performed on August 29, 2018. The samples consisted of four from the IFR, two from the former photo-processing trailer (TR), and one from the spent ammunition “lead pile” (LP). As the Site may be redeveloped in the future, the construction worker MDEP RAG of 450 milligrams per kilogram (mg/kg) was used in


the evaluation of exceedances. Soil samples collected near the IFR included one from each of four openings to the exterior as illustrated on Figure 5. Analytical samples collected along the east side of the IFR included IFR-17 (adjacent to existing doorway that entered the IFR) and IFR-27 (adjacent to the doorway that accesses the storage room located behind and south of the IFR) where XRF screening values for lead were 4,376 mg/kg and 4,044 mg/kg, respectively. Confirmatory laboratory results for these samples, as reported by Alpha, were 2,850 mg/kg and 5,290 mg/kg, respectively. Lead concentration in both samples exceeded the construction worker RAG of 450 mg/kg. Soil samples collected along the west side of the IFR were collected adjacent to a wall-mounted exhaust fan for the IFR (IFR-4) and window to the storage room (IFR-5). Sample IFR-4 detected lead at a concentration of 542 mg/kg, above the MDEP RAG. Alternatively, sample IFR-5 detected lead at a concentration of 315 mg/kg, below the applicable RAG. These results are consistent with anticipated exposure to lead dust from the IFR relative to the size of opening and proximity/connection to the former IFR. Wipe samples, as collected by Summit during the 2007 Phase II ESA, detected the highest lead concentrations at the IFR floor and on exhaust fan blades.

A total of 36 locations were field-screened with an XRF for lead and silver around the trailer (Figure 6) believed to have been a location where photo-processing was performed. Two soil samples were submitted to Alpha for RCRA 8 metals analysis. Screening locations TR-5 and TR-15 contained the highest XRF screening values of 40 mg/kg and 80 mg/kg for lead, respectively, with field screening for silver reported as not detected (ND). Confirmatory soil samples submitted to the laboratory for these two locations detected lead at concentrations of 6.96 mg/kg (TR-5) and 17.6 mg/kg (TR-15), respectively, below the applicable RAG. Silver concentrations being reported as ND, or below the DL for both locations. Screening locations around the spent ammunition waste lead pile were positioned, due to exposed bedrock, to account for the flow of precipitation as surface water towards and across the visible spent lead fragments. A total of 18 XRF screening locations were completed with a confirmatory soil sample submitted to the laboratory for analysis of lead from LP-13B (Figure 7). Location LP-13 was screened via XRF twice (LP-13 and LP-13B) due to the high amount of lead recorded by the instrumentation (1.66% and 5,160 mg/kg). Analytical results detected lead at a concentration of 9,760 mg/kg, approximately 20 times the current construction worker RAG.

SECTION 7 | CONCLUSIONS Soil and groundwater samples collected as part of this Phase II ESA were intended to identify and evaluate the potential risk to receptors within the area of investigation. Based on the observations made during field activities, field screening, and laboratory analysis of submitted soil and groundwater samples, evidence of PFAS impacts above applicable remediation action guidelines were identified at several areas within the Site. These results correlate with the findings of the investigation completed by MDEP in May 2018. Subsurface soil samples collected for PFAS analysis from DPT borings did not result in concentrations above applicable leaching to groundwater RAGs and would indicate that limited risk exists within shallow subsurface soils. Despite there being limited evidence to suggest a significant risk within subsurface soils, concentrations of PFOS above applicable RAGs within surface soils around baled waste material and short paper fiber suggests that some risk may be


present within these areas for leaching to groundwater. Data collected from shallow groundwater during this investigation and from porewater samples collected by the MDEP during their May 2018 sampling indicates that PFAS compounds have impacted overburden groundwater. However, based on limited information available for PFAS compounds in existing drinking water wells adjacent to the Site, it is unknown if risk to receptors are present. Lead in soil was found to be above the applicable RAG for a construction worker to soils sampled around the former IFR and the spent ammunition waste lead pile located west of the office building. These levels represent an elevated risk to the applied RAG; however, final Site remediation alternatives and objectives were not known at the time of this report.

Case Narrative

The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation

or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report.

Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all

NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter

(i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list

for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified Compounds

(TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target Compound List,

even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective

action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE",

respectively. When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element

are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside

the listed Acceptance Criteria is bolded in the report. All specific QC information is also incorporated in the Data Usability format of our Data

Merger tool where it can be reviewed along with any associated usability implications. Soil/sediments, solids and tissues are reported on a

dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary

located at the back of the report.

In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some

quality control failures to occur and still be within method compliance. In these instances the specific failure is not narrated but noted in the

associated QC table. The information is also incorporated in the Data Usability format of our Data Merger tool where it can be reviewed

along with any associated usability implications.

Please see the associated ADEx data file for a comparison of laboratory reporting limits that were achieved with the regulatory Numerical

Standards requested on the Chain of Custody.

HOLD POLICY

For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days

from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless

you have contacted your Client Service Representative and made arrangements for Alpha to continue to hold the samples. Air canisters will

be disposed after 3 business days from the date the project is completed.

Please contact Client Services at 800-624-9220 with any questions.

I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and belief and based upon my personal inquiry of those responsible for providing the information contained in this analytical report, such information is accurate and complete. This certificate of analysis is not complete unless this page accompanies any and all pages of this report.

Case Narrative

Sample Condition on Receipt:

Eighteen soil samples were received in good condition and within the method temperature requirements. The

samples were received and stored securely in accordance with Vista standard operating procedures and EPA

methodology.

Analytical Notes:

VAL-PFAS

The samples were extracted and analyzed for a selected list of PFAS using VAL Method PFAS. The results for

PFHxS, PFOA, PFOS, MeFOSAA and EtFOSAA include both linear and branched isomers. Results for all other

analytes include the linear isomers only.

Holding Times

The samples were extracted and analyzed within the hold times. All re-extractions were extracted within the

method hold times.

Quality Control

The Initial Calibration and Continuing Calibration Verifications met the method acceptance criteria.

The following samples were re-extracted because of low IS recoveries:

Laboratory ID Sample Name

1802726-16 DPT-02 (13-14)

1802726-18 DPT-DUP 2

A Method Blank and Ongoing Precision and Recovery (OPR) sample were extracted and analyzed with the

preparation batch for the original samples and for the re-extractions. No analytes were detected in the Method

Blank above 1/2 the LOQ for either Method Blank. The OPR recoveries were within the method acceptance

criteria for both OPRs.

As requested, an MS/MSD was performed on sample "DPT-05 (5-6)". The MS/MSD recoveries and RPDs were


within the method acceptance criteria.

The labeled standard recoveries outside the acceptance criteria are listed in the table below.

Case Narrative

Sample Condition on Receipt:

Nine soil samples and three aqueous samples were received in good condition and within the method temperature

requirements. The samples were received and stored securely in accordance with Vista standard operating

procedures and EPA methodology.

Analytical Notes:

PFAS Isotope Dilution Method

The aqueous samples were extracted and analyzed for a selected list of PFAS using Vista's PFAS Isotope Dilution

Method. This method is listed on Vista's NELAP certificate as Modifed EPA Method 537. The results for

PFHxS, PFOA, PFOS, MeFOSAA and EtFOSAA include both linear and branched isomers. Results for all

other analytes include the linear isomers only.

Samples "TW-2" contained particulate and were centrifuged prior to extraction.

Holding Times

The samples were originally extracted and analyzed within the method hold times. The samples required

re-extractions, which were performed outside of the hold time.

Quality Control



preparation batch. No analytes were detected in the Method Blank above 1/2 the LOQ. The recoveries of

MeFOSA was greater than 130% in the OPR. This analyte was not detected in the samples. The recoveries of all

other analytes were within the method acceptance criteria.


VAL-PFAS

The soil samples were extracted and analyzed for a selected list of PFAS using VAL Method PFAS. The results

for PFHxS, PFOA, PFOS, MeFOSAA and EtFOSAA include both linear and branched isomers. Results for all

other analytes include the linear isomers only.

Holding Times

The samples were extracted and analyzed within the hold times.


Quality Control



preparation batch. No analytes were detected in the Method Blank above 1/2 the LOQ. The OPR recoveries

were within the method acceptance criteria.
