(GZA) has prepared this Draft Immediate Response Action (IRA) Plan Modification for the above-referenced disposal site (the “Site”). The Massachusetts Department of Environmental Protection (MassDEP) identifies the disposal site as Release Tracking Number (RTN) 4-26179. The IRA is being performed to address a release of per- and polyfluoroalkyl substances (PFAS) related to historic activities at the former Barnstable Municipal Fire Training Facility (MFTF) located at 155 South Flint Rock Road in Barnstable (Hyannis), Massachusetts. This fifth IRA Plan Modification has been prepared for injection of a full-scale permeable reactive barrier (PRB) proximate to the eastern and southern (hydraulically downgradient) property lines of the former MFTF. The PRB will consist of injection of a Colloidal Activated Carbon (CAC) material called PlumeStopTM manufactured by Regenesis to mitigate migration of PFAS from the Site. The feasibility of the CAC PRB was evaluated via a pilot-scale test implemented at the Site in October/November 2024 pursuant to the project’s 4th IRA modification1. The results of the pilot test are discussed further below. A CAC PRB acts as a vertical permeable “wall” installed below ground to treat and remediate contaminated groundwater flowing through it. Adsorbent (reactive) materials (in this case, the CAC product PlumeStopTM) are injected into the subsurface within the saturated groundwater zone, thereby creating a treatment barrier or zone. The PRB allows groundwater to flow through it while PFAS and/or other organic compounds are sorbed onto the CAC. For additional technical reference, a copy of the United States Environmental Protection Agency (USEPA) Community Guide to Permeable Reactive Barriers is provided in Appendix A. While a PRB will not remove PFAS from the subsurface, it will serve to mitigate further migration of PFAS from the MFTF Site and could, in conjunction with other remedial technologies, support the achievement of a Permanent or Temporary Solution, or Remedy Operation Status for the Site. 1 GZA, September 4, 2024, “Immediate Response Action Plan No. 4, Former Barnstable County Municipal Fire Training Facility.” May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 2 Proactive by Design This Draft IRA Plan Modification has been prepared in accordance with 310 CMR 40.0424, and 40.0046 of the Massachusetts Contingency Plan (MCP; 310 CMR 40.0000). This report is subject to the Limitations provided in Appendix B. The IRA Transmittal Form (BWSC105) was submitted electronically in accordance with the current MassDEP policy, a copy of which is provided in Appendix C. BACKGROUND Site History and Use The former MFTF is currently owned by the County of Barnstable and includes the former fire training building (which houses administrative offices, former classrooms, and two apparatus bays), and several ancillary structures, including a former classroom building (currently being used for storage), two Quonset-style sheds (also being used for storage), a small concrete building which houses a groundwater treatment system, a metal shipping container which houses a second groundwater treatment system, a small, vacant, concrete block storage shed, and associated paved driveways/parking areas, and landscaped areas. The MFTF is secured by a chain link fence and a locked gate. A Site Locus Plan is included as Figure 1 and a Site Plan is included as Figure 2. The MFTF has been used for public safety training by numerous fire departments and fire districts throughout Barnstable County and the Commonwealth since the 1950s. Firefighting training exercises, including the use of firefighting foams (including aqueous film-forming foam; AFFF) were conducted at the MFTF until operations ceased in 2009. AFFF is known to contain PFAS compounds, including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). In addition to the use of PFAS-containing foams, other fire training activities included the controlled burning of #2 fuel oil in concrete pits and extinguishing of those burns with water, carbon dioxide, and fire suppressant foam. According to historical reports, the use of petroleum products was discontinued in 1986. Response actions to mitigate residual petroleum releases were conducted under RTN 4-190. The most active area for firefighting training was located at the southwest corner of the MFTF where a “Flame Prop” and “Propane Tank Prop” were used. Fire suppressant foam training exercises at the MFTF ceased in 2009. Water training activities subsequently ceased in June 2019. The residual fire training structures, props, and other infrastructure has since been demolished and/or removed from the MFTF. The MFTF consists of approximately 6.2-acres of land and pond located in an industrial-zoned area of Barnstable (Hyannis), Massachusetts. The land surrounding the MFTF is primarily undeveloped, wooded land with public water supply protection areas. Flintrock Pond occupies approximately 6 acres to the west of the MFTF. The land to the east and southeast of the MFTF is owned by the Town of Barnstable and is divided by two electric transmission/power line easements. Private industrial properties and related structures are located between approximately 500 and 1,000 feet south of the MFTF. The Barnstable Municipal Airport is also located to the south of the MFTF. The nearest residential properties are located approximately 0.25 miles north of the MFTF. There are no known Institutions (as defined within the MCP) located within 500 feet of the Site. Nearby Groundwater Supply Usage A review of the Massachusetts GIS Priority Resource Map identifies the Site as being located within a Zone II Public Water Supply Protection Area, a Medium-Yield Sole Source Aquifer, and a United States Environmental Protection Agency (USEPA) Sole Source Aquifer. Therefore, the MCP GW-1 groundwater category applies to the Site. Groundwater has been measured at depths less than 15 feet below ground surface at the MFTF where an occupied non-residential building is present; therefore, the MCP GW-2 groundwater category also applies to a portion of the Site. All groundwater within the Commonwealth is considered a potential source of discharge to surface waters and is categorized as GW-3, therefore the applicable MCP groundwater categories for the Site are GW-1, GW-2, and GW-3. May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 3 Proactive by Design Several public water supply wells and associated infrastructure are located to the east, southeast, and west of the MFTF, Including: · Mary Dunn Wells 1, 2, and 3 (designated MD-1, MD-2, and MD-3, respectively) located approximately 1,000 to 1,700 feet east/southeast of the MFTF and owned and operated by the Hyannis Water Supply Division (HWSD); · Seasonally operated well designated Air-1, located approximately 3,000 feet southeast of the MFTF and owned and operated by the HWSD; · Maher Wells 1, 2, and 3 (designated ME-1, ME-2, and MW-3, respectively), located approximately 1.4 miles southeast of the MFTF and owned and operated by the HWSD; and · Barnstable Fire District (BFD) wells 2, and 5 (designated BFD-2, and BFD-5) located approximately 1,000 feet west of the MFTF, and owned and operated by the BFD. There are no known private water supply wells located within the preliminary disposal site boundary. Nearby Surface Water Bodies The nearest surface water bodies to the Site are: · Flintrock pond, located to the west and adjacent to the MFTF; · two unnamed ponds located to the northeast of the MFTF; · Little Isreal Pond and Isreal Pond located to the northeast of the MFTF, and · Mary Dunn Pond, located to the southeast of the Site. Flintrock Pond is located within the preliminary disposal site boundary based on the detection of PFAS in sediment and surface water within the pond. The nearest unnamed pond to the northeast of the MFTF has been identified as a Natural Heritage and Endangered Species (NHESP) vernal pool according to the Massachusetts GIS website (MassMapper) and GZA’s field investigations. There are no mapped streams or wetlands located at the Site according to MassDEP mapping: however, undocumented wetlands and other potential protection areas may be present within the disposal site. Historical Releases Four MassDEP RTNs have been issued for the Site and/or nearby Sites: · 4-190 (petroleum release as noted above); · 4-11707 (petroleum release from UST); · 4-20021 (perchlorate release); and · 4-26179 (PFAS release). Regulatory closure in the form of a Class A-2 Response Action Outcome (now known as a Permanent Solution with No Conditions) was achieved for RTN 4-11707. MassDEP records indicate that RTN 4-20021 was linked to 4-190. In addition, RTN 4-0937 which is related to a release of chloroform from the upgradient property located at 100 Breeds Hill Road in Barnstable, Massachusetts, historically impacted the Site. A Permanent Solution was achieved for RTN 4-0937 in 2003. May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 4 Proactive by Design On November 30, 2013, water samples were collected from the Mary Dunn Public Water Supply Wells (MD-1, MD-2, and MD-3) and analyzed for PFAS under the USEPA Unregulated Contaminant Monitoring Rule (UCMR3) program. Elevated concentrations of PFOS and/or PFOA were detected in those samples. Given that PFAS were also detected at elevated concentrations in the soil and groundwater at the MFTF, and that the groundwater flow direction is from the MFTF toward the Mary Dunn Wells, MassDEP determined that releases of PFAS from the use of AFFF at the MFTF is a source of PFAS detected in the Mary Dunn Wells. Releases of oil and/or hazardous materials (OHM) that impact public water supplies could also pose an Imminent Hazard. Accordingly, MassDEP issued Barnstable County a Notice of Responsibility (NOR) on August 4, 2016, and assigned RTN 4-26179. The NOR outlined the following activities to be performed as part of the IRA: · Excavating the identified soil “Hot Spot” contaminated with PFAS that is acting as an on-going source of groundwater contamination; and/or · Expanding the existing groundwater recovery and treatment system to include additional recovery wells or an increase pumping rate to decrease the mass of PFAS in the groundwater at the MFTF. On behalf of Barnstable County, the Cape Cod Commission submitted an IRA Plan to MassDEP on September 27, 2016, which included a plan to address the release of PFAS related to the use of fire-fighting foams at the MFTF. The IRA Plan stated that a PFOS Hot Spot was present in the southwestern portion of the MFTF, where an unpaved sump was previously located, and that a concentrated PFOS plume was migrating toward well PRW-4. A soil sample from 4-8 feet below ground surface (bgs) at boring B-3 in the Hot Spot area reportedly had a PFOS concentration of 4,900 micrograms per kilogram (“µg/kg” or parts per billion), compared to the current (2024) MCP Method 3 Ceiling Limit (M3CL)2 of 4,000 µg/kg, and a soil sample collected just below the pavement from nearby boring HS-7 had 2,000 µg/kg PFOS. The reported PFOS concentrations in groundwater samples were 220,000 nanograms per liter (“ng/L” or parts per trillion) at PFW-2 in the Hot Spot Area in April 2015; 60,000 ng/L at PFW-1 in the southeast corner in October 2015; and 17,000 ng/L at PRW-4, located approximately 750 feet southeast of PFW-1, in September 2015. The 2016 IRA Plan proposed the excavation of approximately 200 cubic yards of impacted soil from the Hot Spot, with a proposed 200-square foot (sf) area excavated to approximately 10 feet bgs and another 200-sf area excavated to approximately 5 feet bgs. The IRA Plan further proposed the amendment of the soil at the base of the excavation with a carbon material amendment commercially sold as Rembind, which consists of activated carbon supplemented with alum. The intent of the Rembind additive was for the amendment to “absorb remaining PFOS in the soil.” It was noted that the product could result in the leaching of copper and aluminum to subsurface soils. In November 2016, MassDEP conditionally approved the IRA Plan, with a requirement that it be implemented in accordance with the Remedial Additive provisions of the MCP (310 CMR 40.0046) and that upgradient and downgradient groundwater samples be collected for analysis of the MCP-14 metals to assess for potential leaching impacts associated with the Rembind additive. The IRA Plan was modified on June 28, 2018, in response to a Notice of Audit Findings – Immediate Response Action Field Inspection and Request for IRA Modification/Interim Deadline, issued by MassDEP dated June 1, 2018, to describe proposed interim modifications at the MFTF to improve stormwater and fire training water control and address flow towards the former Hot Spot area. A second IRA Plan Modification was submitted to MassDEP on December 20, 2019, in response to a directive from MassDEP to provide details for the expansion of the groundwater recovery and treatment system and capping measures to prevent infiltration of the precipitation through soils at the MFTF. The IRA Plan was modified a third time with the submittal of IRA Plan Modification No. 3, dated June 22, 2021, to formalize the inclusion of selected building demolition as part of the IRA. 2 Previously referred to as an Upper Concentration Limit (UCL). May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 5 Proactive by Design In September 2024, an IRA Modification was submitted for the performance of a pilot test CAC PRB to evaluate the feasibility and efficacy of a CAC PRB as a response action to mitigate further migration of PFAS from the MFTF. Details of IRA activities conducted under the IRA Plan and subsequent modifications are discussed below. PRIOR IMMEDIATE RESPONSE ACTION ACTIVITIES Since the submittal of the initial IRA Plan in September 2016, investigation and remedial response actions have been conducted to address the PFAS impacts at the Site. This section summarizes the status of prior IRA activities, including those that are ongoing. Additional details regarding these IRA activities can be found in previous IRA status reports which have been submitted to MassDEP by others. GZA’s review of MassDEP files3 indicates that the following key remedial response actions have been conducted at the MFTF as interim and IRA response actions: · In July 2015, existing recovery well PRW-4, which had been previously installed as a recovery well associated with the former perchlorate release, was reactivated in an attempt to contain PFAS-impacted groundwater. The captured groundwater is then treated for PFAS via granular activated carbon treatment system (designated as GWTS #1). The capture zone of PRW-4was estimated to be approximately 200 feet at a pumping rate of 40 gallons per minute (gpm); the initial pumping rate was approximately 38 gpm. The extracted groundwater is pumped via two 2-inch-diameter force mains to the GWTS-1 system. The treated groundwater is discharged to the subsurface via recharge/infiltration chambers located in the north-central area of the MFTF. Spent GAC is transported off- Site for thermal regeneration or destruction. · In January 2017, the Hot Spot area was excavated to depths between 5 and 10 feet bgs, and Rembind was placed in the bottom of the excavation prior to backfilling, with the goal of reducing subsequent leaching of PFAS from the soil to groundwater. It was noted in more recent IRA status reports that post-excavation settling in the Hot Spot area left that area prone to infiltration of runoff from the southern portion of the MFTF. Following the submittal of IRA Plan Modification No. 1 in June 2018, Phase 1 Stormwater Management Improvements were completed between December 2018 and February 2019 to re-direct stormwater and fire training runoff water away from the Hot Spot area and Flintrock Pond, including placement of fill, polyethylene sheeting, and peastone over the former Hot Spot. · In accordance with IRA Plan Modification No. 2, submitted in December 2019, a second groundwater treatment system GWTS #2 was constructed and added to provide additional temporary groundwater treatment capacity. This system is served by one of the force mains from GWTS #1, and it consists of two 1,300-pound GAC vessels housed in a heated shipping container. A new 4-inch PVC gravity discharge line was installed below grade and discharged to one of the existing recharge basins to the north. · Following the submittal of IRA Plan Modification No. 3 in June 2021, the County completed a property-wide capping and select building demolition at the former MFTF between August and October 2021. The project included the demolition and removal of the former burn buildings and other fire training props; off-site disposal of approximately 650 tons of PFAS- contaminated demolition debris; construction of an asphalt cap over approximately 59,000 square feet of the MFTF; and installation of new stormwater drain structures, catch basins, a dual-chamber oil-water separator (Stormceptor) and stormwater discharge structure on the west side of the MFTF. 3 Some of the key 2017-era reports on the Energy and Environmental Affairs (EEA) Data Portal are labeled “portfolio.pdf” and were not accessible to GZA. May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 6 Proactive by Design · Between October 23, and November 1, 2025, GZA initiated a field level pilot test of the proposed PRB in the southeast area of the MFTF in accordance with IRA Plan Modification No 4. This test included installation of additional pilot test monitoring wells located upgradient, downgradient, and within the pilot test area and injection of approximately 24,000 lbs. of PlumeStopTM CAC slurry into the subsurface. Although the post-injection groundwater monitoring indicates localized downgradient CAC dispersion from the injection area, the results also indicate favorable PFAS removal effectiveness. Pre and post CAC injection monitoring results are summarized in Table 1. This IRA Plan Modification No. 5 to inject a full-scale CAC PRB has been prepared based on the favorable initial results of the PRB pilot test. IMMEDIATE RESPONSE ACTION PLAN MODIFICATION NO. 5 This Draft IRA Plan Modification is being submitted to describe the implementation of a full-scale in-situ CAC PRB as a response action to limit the migration of PFAS-related compounds in groundwater from historic use of fire-fighting foams at the MFTF. PERMEABLE REACTIVE BARRIER INJECTION The highest concentrations of PFAS in groundwater at the Site have been detected within the boundaries of the MFTF property. Soil and groundwater residually impacted by PFAS at the MFTF appears to be a continuing source of off-Site PFAS migration. A full-scale CAC PRB will be installed along the downgradient edge of the MFTF property (south and east property limits) to mitigate further migration of PFAS from the MFTF property. Groundwater in the vicinity of the MFTF property flows to the east and southeast, partially influenced by the groundwater mound associated with the on-Site groundwater treatment system effluent re-injection gallery. Thus, the CAC PRB will be injected along both the eastern and southern MFTF property boundaries as shown on Figure 2. Please note that this alignment may be altered slightly based on equipment access and other field conditions. After a Request for Proposal and competitive bid process, the County selected Regenesis Remediation Services (Regenesis) to design and execute the full-scale PRB. Regenesis is a commercial designer and vendor of remediation products related to the containment and/or destruction of certain environmental contaminants. Consistent with the pilot test, Regenesis’ PlumeStop® CAC formula will be utilized for the full-scale PRB. The PRB will involve injecting CAC within two rows of injection points spaced approximately 5 feet apart. The CAC will be injected from the top of the observed silty clay layer (approximately 60 to 94 feet bgs) up to the groundwater surface as described below. In February 2025, GZA subcontracted Hager GeoScience, Inc. of Woburn, Massachusetts (HGS) to perform a geophysical survey along the proposed alignment of the full-scale PRB to assess the depth to the silty clay layer. To date, HGS provided GZA with a preliminary stratigraphic profile developed using low-frequency ground penetrating radar (LGPR) for the eastern property boundary. HGS’s interpretation of the LGPR data indicates that the depth to the top of the clay ranges between approximately 70 to 80 feet bgs, generally consistent with the observations of the soil borings previously completed at the Site. Between March 26, 2025, and May 12, 2025, a total of nine additional multi-level PRB performance validation wells (PV wells) were installed approximately 30 feet hydraulically downgradient of the proposed PRB alignment. In general, at each PV well location, a deep member well was drilled to the top of the silty clay layer, a shallow member well was installed at the water table, and an intermediate well was installed between the shallow and deep member wells. The depth to the clay encountered at these well locations ranged from approximately 63 to 94 feet below ground surface, generally consistent with LGPR and prior well installations. The efficacy of the PlumeStop® PRB will be evaluated based on the pre- and post-injection groundwater monitoring using new PV wells (designated GZ-4S/I/D through GZ-12S/I/D) on Figure 2. As noted above, the PV wells were constructed as May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 7 Proactive by Design multi-level triplets with shallow, intermediate, and deep well screened intervals. The target depths and rationale for the PV wells are presented below: Target Monitoring Zone Approximate Depth (BGS) Rationale Shallow 15-25 feet (outwash sand) · Intercept the local water table · Assess shallow hydraulic gradient · Monitoring shallow groundwater quality · Assess hydraulic properties of the aquifer materials Intermediate 30-50 feet (outwash sand) · Monitor intermediate groundwater quality · Assess vertical hydraulic gradient · Assess hydraulic properties of the aquifer materials Deep 60-94 feet (base of the outwash sand) · Monitor deep groundwater quality · Assess vertical hydraulic gradient · Confirm depth to the underlying silt/clay confining layer · Assess hydraulic properties of the aquifer materials At each well cluster, the deep member of the PV well triplet was drilled first with soil sampling at select intervals for hydrogeological lithologic descriptions. The depths and construction details for the intermediate and shallow members were selected based on the logged information from the deep soil boring. Because of site soil conditions that demonstrate instability and flow into the drilling equipment due to hydraulic pressures at depth (referred to as running sands) 4, the borings for the deep and intermediate level wells were advanced using drive and wash casing drilling methods while maintaining positive water head within the casing. This drilling method affords more options for controlling running sands while collecting soil samples for lithologic descriptions; however, it requires the use of (and potential loss) of significant quantities of drilling water. Hollow stem auger drilling methods were used to advance the soil borings for the shallow members of the PV well locations to limit the use of drilling water. Only PFAS-free potable water from the Hyannis municipal water system was utilized for the drilling operations. Following well installation, GZA will develop the new wells using conventional over-pumping and surging techniques. GZA will then collect baseline (i.e., prior to PRB installation) groundwater samples from each new PV well for PFAS analysis via EPA Method 1633 and total organic carbon (TOC). Regenesis will utilize Direct Push Technology to inject the PRB from the top of the observed silty clay layer (approximately 63 to 94 feet bgs) up to the water table (approximately 15 feet bgs) along the approximately 615-foot alignment. As with the drilling, only PFAS-free municipal water will be utilized to create the CAC slurry prior to injecting. It is anticipated that the PlumeStop® product will be injected in two rows at approximately 246 total injection points spaced approximately 5 feet apart; a total of approximately 388,000 lbs. of PlumeStop® (591,360 gallons of solution) will be injected below ground surface. Regenesis anticipates applying two different dosages of PlumeStop® product along the PRB. PFAS concentrations in groundwater in the southern portion of the MFTF property are one to two orders of magnitude greater than those in 4 Running sands occur when water saturated loosely-packed sands become fluidized and are carried into a borehole or other type of void as a result of lateral and/or upward flow water into the drilling equipment. May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 8 Proactive by Design the northern portion of the property. Accordingly, a higher dosage of PlumeStop® product will be injected along the southern property boundary and the southern portion of the eastern property boundary. During the injections, placement verification testing, via soil cores and/or water samples, will be conducted to assess the dispersion of the PlumeStop®. The initial target injection concentrations, volume per vertical foot, injection intervals, and/or spacing between injection points may be adjusted based on the results of the placement verification testing. It is anticipated that the injections will take approximately 12 consecutive weeks to complete using two concurrent injection rigs and crews. Given the target depth of the injections, GZA does not anticipate that the PRB will erode or otherwise impair the function of surficial or subsurface soils. Past experience with similar injection programs indicates that surficial breakthrough (daylighting) of PlumeStop® (if any) will be limited to the ground surface in the immediate area of the injection point. GZA notes that the majority of the PRB will be implemented within paved areas of the MFTF and PlumeStop® that may accumulate on the paved surface will be managed during the installation process. Further, except for the force mains for the groundwater extraction system, no other underground utilities or buildings are located in the immediate vicinity of the proposed PRB alignment. In addition, given the hydraulic conductivity of the surficial sands underlying the MFTF, groundwater mounding within two feet of the ground surface is not anticipated. Should daylighting or mounding occur, injection rates will be reduced to alleviate the condition. The southwestern portion of the proposed PRB alignment (approximately 70 linear feet) is located within the 100-foot buffer zone to Flintrock Pond. Additionally, the northern portion of the proposed PRB alignment (approximately 50 linear feet) is within the 100-foot buffer zone of a vernal pool and vegetated wetlands. On April 28, 2025, GZA, on behalf of Barnstable County, submitted a Notice of Intent (NOI) to the Barnstable Conservation Commission for the PRB injections within the 100-foot buffer zones. Based on past experiences at similar Sites, Regenesis does not anticipate that the PlumeStop® will migrate to Flintrock Pond or the vegetated wetlands given the distance and relatively low hydraulic gradient; however, GZA personnel will monitor Flintrock Pond and the wetlands for potential breakout of the PlumeStop® throughout the implementation of the PRB. If breakout is observed in Flintrock Pond, the PlumeStop® injections will be immediately discontinued while an alternative plan is developed, such as the use of Regenesis’ AquiFix® product that limits the migration of PlumeStop® in the subsurface. PlumeStop® contains a polymerized coating which allows the particles to temporarily remain suspended in solution while the product disperses in the subsurface. According to information provided by Regenesis, the coating consists of a water- soluble, food-grade polymer that is classified as not persistent, not bio-accumulative, and non-toxic and degrades completely when it ends up in the environment. MassDEP has reviewed the propriety ingredients of PlumeStop® and the polymerized coating and approved the use of the product in an email dated August 26, 2024 (Appendix D). GZA will visually monitor groundwater wells hydraulically downgradient of the PRB injection area to assess if CAC migration is occurring. The expected radius of influence of the PRB injections is approximately 10 feet, therefore, migration of the CAC to the public drinking water supply wells (Mary Dunn wells) located more than 1,000 feet south/southeast of the Site is not anticipated. Should migration of PlumeStop® be observed in downgradient monitoring wells, which are located approximately 30 feet away from the PRB injection locations, GZA will work with Regenesis to mitigate migration. If necessary, a calcium chloride salt, such as the AquiFix® product, can be applied to prevent further migration. The calcium chloride salt acts as a destabilizing agent which will cause the Plume Stop® particles to agglomerate via cation bridging, increasing the particle size, and preventing further transport. Following the completion of the PlumeStop® PRB injections, GZA will conduct post-injection groundwater monitoring at the downgradient PV wells (GZ-4S/I/D through GZ-12S/I/D) to assess the effectiveness of the PlumeStop® PRB. On a monthly basis, for the first three months following the PlumeStop® injections, GZA personnel will collect groundwater samples from these wells to visually assess for the presence of CAC and monitor for migration of PlumeStop®. On a May 14, 2025 Massachusetts Department of Environmental Protection File No. 01.0177641.20 Page | 9 Proactive by Design quarterly basis, GZA personnel will collect groundwater samples from the PV wells for analysis of PFAS via EPA Method 1633 and TOC. Quarterly monitoring will continue for one year at which time the monitoring frequency will be re- evaluated. SCHEDULE It is anticipated that the PlumeStop® CAC injections will be initiated during the summer and early fall of 2025 following approval of this Draft IRA Plan Modification. The PlumeStop® injections are anticipated to take approximately 12 weeks to complete. Baseline groundwater samples are anticipated to be collected from the new downgradient PV wells in May 2025. Post-remedial monitoring of the carbon content within the downgradient PV monitoring wells will take place on a monthly basis for the first three months following the PlumeStop® PRB installation. Groundwater samples will be collected from these wells for PFAS and TOC analysis on a quarterly basis for up to one year, at which time the monitoring frequency will be re-evaluated. The activities described in this IRA Plan Modification will be summarized in a future IRA Status Report. MANAGEMENT OF REMEDIATION WASTES Remediation waste is not anticipated to be generated during implementation of the PRB as described above.

Proactive by Design Appendix A - USEPA Community Guide to Permeable Reactive Barriers Community Guide to Permeable Reactive Barriers What Is A Permeable Reactive Barrier? A permeable reactive barrier, or “PRB,” is a wall created below ground to clean up contaminated groundwater. The wall is “permeable,” which means that groundwater can flow through it. Water must flow through the PRB to be treated. The “reactive” materials that make up the wall either trap harmful contaminants or make them less harmful. The treated groundwater flows out the other side of the wall. How Does It Work? PRBs are usually built by digging a long, narrow trench in the path of contaminated groundwater flow. The trench is filled with a reactive material, such as iron, limestone, carbon or mulch, to clean up contaminants from groundwater. Due to limitations of excavation equipment, PRBs typically can be no deeper than 50 feet. However, a deeper but usually shorter PRB can be built by drilling a row of large-diameter holes or by using fracturing. (See Community Guide to Fracturing for Site Cleanup.) Fracturing methods connect the reactive material to deeper contaminated groundwater. The reactive material selected for the PRB will depend on the types of contaminants present in the groundwater. The material may be mixed with sand to make the wall more permeable so that it is easier for groundwater to flow through it, rather than around it. Side walls filled with a less permeable material such as clay may be constructed at an angle to the PRB to help funnel the flow of contaminated groundwater toward the reactive materials. The filled trench is covered with soil. Depending on the reactive material, contaminants are removed through different processes: •Contaminants sorb (stick) to the surface of the reactive material. For example, carbon particles have a surface onto which contaminants, such as petroleum products, sorb as groundwater passes through. •Metals dissolved in groundwater precipitate, which means they are removed from groundwater by forming solid particles that get trapped in the wall. For example, limestone and shell fragments can cause dissolved lead and copper to precipitate in a PRB. •Contaminants react with the reactive material to form less harmful ones. For example, reactions between metallic iron particles in a PRB and certain industrial cleaning solvents can convert the solvents to less toxic or even harmless chemicals. •Contaminants are biodegraded by microbes in the PRB. Microbes are very small organisms that live in soil and groundwater and eat certain contaminants. When microbes digest the contaminants, they change them into water and gases, such as carbon dioxide. (See Community Guide to Bioremediation.) Organic mulch frequently is used as reactive media in this type of PRB. Mulch barriers consist of plant-based materials, such as compost or wood chips, and naturally contain many different microbes. Groundwater flow through the PRB also releases organic carbon from the mulch wall, creating another reactive zone for contaminants just beyond the wall. Microbes also can make some contaminants (like arsenic and uranium) less soluble in groundwater by changing their chemical form. Over time, PRBs can fill up with sorbed or precipitated contaminants, making them less effective at cleaning groundwater. When this occurs, the contaminated reactive material may be excavated for disposal and replaced with fresh material. PRB treats a plume of groundwater contaminants. How Long Will It Take? PRBs may take many years to clean up contaminated groundwater. The cleanup time will depend on factors that vary from site to site. For example, PRBs will take longer where: •The source of dissolved contaminants (for instance, a leaking drum of solvent) has not been removed. •The contaminants remain in place because they are not easily dissolved by groundwater. •Groundwater flow is slow. •The reactive material must be replaced frequently. Are PRBs Safe? The reactive materials placed in PRBs are not harmful to groundwater or people. Contaminated groundwater is cleaned up underground, so treatment does not expose workers or others onsite to contamination. Because some contaminated soil may be encountered when digging the trench, workers wear protective clothing. Workers also cover loose contaminated soil to keep dust and vapors out of the air before disposing of it. Groundwater is tested regularly to make sure the PRB is working. How Might It Affect Me? During construction of the PRB, you may see increased truck traffic when materials are hauled to the site, or you might hear earth-moving equipment. However, when complete, PRBs require no noisy equipment. Cleanup workers will occasionally visit the site to collect groundwater and soil samples to ensure that the PRB is working. When the reactive materials need to be replaced, the old materials will have to be excavated and hauled to a landfill. Why Use PRBs? PRBs are a relatively inexpensive way to clean up groundwater. No energy is needed because PRBs rely on the natural flow of groundwater. The use of some materials, such as limestone, shell fragments and mulch, can be very inexpensive, if locally available. No equipment needs to be aboveground, so the property may continue its normal use, once the PRB is installed. PRBs have been selected for use at dozens of Superfund sites and other cleanup sites across the country. Construction of a PRB in Sunnyvale, CA Example Groundwater at the Parker Sanitary Landfill Superfund site in Vermont was contaminated with solvents as a result of past disposal of industrial wastes. In 2000, a cap was placed on the landfill to keep rainfall from seeping into the wastes and causing more contaminants to enter groundwater. In 2005, a PRB was installed to treat groundwater and prevent the flow of contaminants from the site. The 235-foot wide PRB is filled with iron particles and sand and extends 30 feet to 62 feet below the ground surface. Contaminated groundwater from a part of the landfill that received industrial waste flows through the PRB. Groundwater sampling results indicate that cleanup goals are being met by the PRB.

GZA GeoEnvironmental, Inc. (GZA) prepared this Report on behalf of, and for the exclusive use of our Client for the stated purpose(s) and location(s) identified in the Proposal for Services and/or Report. Use of this Report, in whole or in part, at other locations, or for other purposes, may lead to inappropriate conclusions; and we do not accept any responsibility for the consequences of such use(s). Further, reliance by any party not expressly identified in the agreement, for any use, without our prior written permission, shall be at the party’s sole risk, and without any liability to GZA. STANDARD OF CARE 2. GZA’s findings and conclusions are based on work conducted as part of the Scope of Services set forth in the Proposal for Services and/or Report and reflect our professional judgment. These findings and conclusions must be considered not as scientific or engineering certainties, but rather as our professional opinions concerning the limited data gathered during the course of our work. Conditions other than described in this report may be found at the subject location(s). 3. GZA’s services were performed using the degree of skill and care ordinarily exercised by qualified professionals performing the same type of services, at the same time, under similar conditions, at the same or similar property. No warranty, express or implied, is made. Specifically, GZA does not and cannot represent that the Site contains no hazardous material, oil, or other latent condition beyond that observed by GZA during its study. Additionally, GZA makes no warranty that any response action or recommended action will achieve all of its objectives or that the findings of this study will be upheld by a local, state, or federal agency. 4. In conducting our work, GZA relied upon certain information made available by public agencies. Client and/or others. GZA did not attempt to independently verify the accuracy or completeness of that information. Inconsistencies in this information which we have noted, if any, are discussed in the Report. SUBSURFACE CONDITIONS 5. The generalized soil profile(s) provided in our Report are based on widely-spaced subsurface explorations and are intended only to convey trends in subsurface conditions. The boundaries between strata are approximate and idealized, were developed utilizing interpolation/extrapolation methods, and were based on our assessment of subsurface conditions. The composition of strata, and the transitions between strata, may be more variable and more complex than indicated. For more specific information on soil conditions at a specific location refer to the exploration logs. The nature and extend of variations between these explorations may not become evident until further exploration or construction. If variations or other latent conditions then become evident, it will be necessary to reevaluate the conclusions and recommendations of this Report. 6. Water level readings have been made, as described in this Report, in the specified monitoring wells at the specified times and under the stated conditions. These data have been reviewed and interpretations have been made in this Report. Fluctuations in the level of the groundwater, however, occur due to temporal or spatial variations in areal recharge rates and heterogeneities, the presence of subsurface utilities, and/or natural or artificially induced perturbations. The observed water table and hydraulic heads may be other than indicated in the Report. GEOHYDROLOGICAL LIMITATIONS 01.0177641.20 Page | 2 May 2025 Aub COMPLIANCE WITH CODES AND REGULATIONS 7. We used reasonable care in identifying and interpreting applicable codes and regulations necessary to execute our scope of work. These codes and regulations are subject to various, and possibly contradictory, interpretations. Interpretations and compliance with codes and regulations by other parties is beyond our control. SCREENING AND ANALYTICAL TESTING 8. GZA collected environmental samples at the locations identified in the Report. These samples were analyzed for the specific parameters identified in the Report. Additional constituents, for which analyses were not conducted, may be present in soil, groundwater, surface water, sediment, and/or air. Future Site activities and uses may result in a requirement for additional testing. 9. Our interpretation of field screening and laboratory data is presented in the Report. Unless noted otherwise, we relied upon the laboratory’s QA/QC program to validate these data. 10. Variations in the types and concentrations of contaminants observed at a given location or time may occur due to release mechanisms, disposal practices, changes in flow paths, and/or the influence of various physical, chemical, biological, or radiological processes. Subsequently observed concentrations may be other than indicated in the Report. INTERPRETATION OF DATA 11. Our opinions are based on available information and data as described in the Report, and on our professional judgment. Additional observations made over time, and/or space, may not support he opinions provided in the Report. ADDITIONAL INFORMATION 12. In the event that the Client or others authorized to use this report obtain additional information on environmental or hazardous waste issues at the Site not contained in this Report, such information shall be brought to GZA’s attention forthwith. GZA will evaluate such information and, on the basis of this evaluation, may modify the conclusions stated in this Report. ADDITIONAL SERVICES 13. GZA recommends that we be retained to provide services during any future investigations, design, implementation, activities, construction, and/or property development/redevelopment of the Site. This will allow us the opportunity to: i) observe conditions and compliance with our design concepts and opinions; ii) allow for changes in the event that conditions are other than anticipated; iii) provide modifications to our design; and iv) assess the consequences of changes in technologies and/or regulations. CONCEPTUAL SITE MODEL 14. Our opinions were developed, in part, based upon a comparison of site information and data available at the time of development to conditions anticipated within our Conceptual Site Model (CSM). The CSM is based on available GEOHYDROLOGICAL LIMITATIONS 01.0177641.20 Page | 3 May 2025 Aub information, and professional judgment. There are rarely sufficient data to develop a definitive CSM. Therefore, observations over time, and/or space, may vary from those depicted in the CSM provided in this Report. The inherent variability and complexity of subsurface conditions mean that the CSM should be considered a dynamic tool rather than a static representation. Therefore, the CSM should be evaluated and refined (as appropriate) whenever significant new information and/or data is obtained.
