Monitoring and Maintenance Report (Post-Closure Report) has been prepared by Mabbett & Associates, Inc. (Mabbett®) on behalf of the Department of Veterans Affairs (VA) Central Western Massachusetts Healthcare System (CWM HCS) located in Leeds, Massachusetts (the “Site”) under Contract No. 36C241-20-P-0636, Modification No. P00003. The Post-Closure Report provides a summary of the annual environmental monitoring and the maintenance inspection completed at the Site landfill on May 25, 2022. Assessment and field operations associated with this program have been conducted in accordance with the permit requirements specified in the Massachusetts Department of Environmental Protection (MassDEP) Closure Certification Approval Letter for the landfill dated September 12, 2011 (DSWM File #11-214-008) for Facility Number #131329. 1.1 Site Location and Environmental Setting The landfill covers a 3.54-acre portion of a larger 9.648-acre parcel delineated on the Site Plan recorded at the Hampshire County Registry of Deeds (Plan Book 200, Page 108). The larger parcel is owned by the City of Northampton and is the location of the Smith Vocational and Agricultural School in Northampton, Massachusetts. The Site is accessible through the adjacent VA CWM HCS at 421 North Main Street in Leeds, Hampshire County, Massachusetts. Figure 1-1 shows the landfill location, the boundary of the City of Northampton parcel, and the location of the VA hospital property. The approximate latitude and longitude of the central portion of the landfill are 42˚21’09” N and 72˚41’17” W. A Site Map illustrating the layout of the landfill and the groundwater, surface water, and leachate monitoring locations is presented on Figure 1-2. The topography of the Site is established by the landfill, with the highest elevations observed at the top of slope along the northeast/southwest trending landfill. The topography slopes gently from northeast to southwest from the top of the landfill. A steeper slope exists at the southeast edge of the landfill, where the topography drops down into a wetland area adjacent to a forested area south of the Site. An intermittent stream borders the landfill to the north and drainage swales run along the eastern and western perimeters of the landfill toward the south, where two retention basins are present adjacent to the Site entrance to collect stormwater runoff. Based on data collected from previous Site reporting, the groundwater flow direction follows the gentle slope of the topography and appears to be toward the southwest. 1.2 Site History The landfill was primarily used for the disposal of construction and demolition (C&D) waste and was owned and operated by the VA CWM HCS from the 1920s to the 1970s. On February 12, 2003, MassDEP issued a permit approving the Initial Site Assessment (ISA) for the landfill and required completion of a Comprehensive Site Assessment (CSA) in accordance with 310 CMR 40.0318 in order to delineate the extent of waste areas. CSA activities included the advancement of soil borings and construction of six groundwater monitoring wells, excavation of twenty-five (25) test pits, and the removal of one 55-gallon drum and its spilled materials. Subsequent investigative activities identified asbestos containing material (ACM) on the surface of the landfill. On February 24, 2005, MassDEP approved the CSA Report. A subsequent Qualitative Risk Assessment/Method 3 Risk Characterization identified soil as the primary exposure pathway, but concluded that a condition of No Significant Risk to Human Health or the Environment existed and a Condition of No Significant Risk to Safety would exist following the installation of the landfill cap. Accordingly, in an effort to close the landfill in accordance with the Massachusetts Solid Waste Management Regulations (310 CMR 19.000), on May 12, 2008 the MassDEP issued a permit to the VA approving the Corrective Action Design (CAD) in accordance with 310 CMR 19.011, 19.106, and 19.130(31)(c). The approximately 3.5-acre landfill was capped in 2010 with a final cover system consisting of the following components:  12-inch vegetative support layer POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 2 2022 Post-Closure Landfill Monitoring Report.Docx  12-inch sand and geocomposite drainage layer  Geosynthetic clay liner (GCL)  6-inch gas venting/bedding layer  Minimum 6-inch subgrade layer over existing waste and cover Wetland restoration activities were conducted in conjunction with the landfill capping activities. Approximately 14,250 square feet of wetland restoration was conducted during construction activities. In 2011, the MassDEP accepted the “Landfill Closure Certification Report” and subsequently issued a Closure Certification Approval/Determination as well as a letter of compliance certifying that the landfill had received final cover in accordance with the approved plans and specifications. Historical post-closure analytical results for metals and indicator parameters from the three most recent monitoring events performed prior to 2022 are presented in Appendix A. 1.3 Purpose and Scope The landfill was closed by the VA in 2011 with appropriate approvals from the MassDEP. Upon acceptance of the “Landfill Closure Certification Report” for the VA landfill, the MassDEP issued a Closure Certification Approval/Determination and letter of compliance certifying that the landfill has received final cover in accordance with the approved plans and specifications. The letter serves as a permit pursuant to Massachusetts General Laws (MGL) Chapter 111 Sections 150A and 150A1/2 and the regulations promulgated thereunder at 310 CMR 16.000 and 310 CMR 19.000. In accordance with the MassDEP permit’s Site-Specific Conditions, Mabbett prepared this 2022 Post-Closure Landfill Monitoring and Maintenance Report. The purpose of the post-closure monitoring and maintenance activities is to monitor for the potential presence and migration of contaminants in groundwater, surface water, and leachate (if present), and to ensure the long-term structural integrity of the landfill cap and associated drainage, security, and access structures. Annual groundwater characterization is required pursuant to MGL Chapter 111, Section 150A and 310 CMR 19.000 to ensure public health and safety. POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 3 2022 Post-Closure Landfill Monitoring Report.Docx 2.0 LANDFILL INSPECTION AND MAINTENANCE 2.1 Maintenance Program In addition to posting and maintaining clearly visible “No Trespassing” signs at all access locations (Section A), the Site-Specific Conditions of MassDEP Landfill Permit 9-12-2011 stipulate that the following activities be performed as part of the maintenance program for all areas of the landfill: a) Cutting vegetation over all phases of the landfill at least once per year to prevent the establishment of deep-rooted vegetation. b) Monitoring of leachate seeps. c) Monthly inspections for settlement and erosion. d) Monitoring of swales, culverts, and basins for erosion, soil build-up and periodic cleaning, as necessary. e) Confirming that the landfill gate is locked. f) Viewing monitoring wells and confirming that locks are in place. g) Repairs are made as required. Additionally, the Landfill Permit stipulates that the VA shall have its employees perform monthly inspections of the landfill. A logbook shall be maintained summarizing the time and findings of each inspection. At a minimum, the monthly inspection shall address the items in the maintenance program above VA personnel documented the performance of monthly landfill inspections throughout the time period covered by this report. 2.2 Third Party Inspection In accordance with 310 CMR 19.018(6)(b)(2) and 310 CMR 19.143, third party inspections of the VA CWM HCS landfill should be performed by a registered MassDEP Third-Party Inspector (TPI) at least once every two calendar years to confirm that the VA is maintaining, caring for, and monitoring the Site during the post-closure period, as well as documenting the integrity of the closure measures, and detecting and preventing any adverse impacts of the Site on public health, safety, or the environment. The last third-party inspection performed at the VA CWM HCS landfill occurred on May 4, 2021. As such, no third- party inspection was performed as part of the 2022 Post-Closure Landfill Monitoring and Maintenance. The next third-party inspection is scheduled for May 2023.

A photographic log illustrating the conditions at each of the sampling locations on May 25, 2022 is included as Appendix B. In accordance with 310 CMR 19.132 and as established in MassDEP Landfill Permit 9-12-2011, the groundwater, surface water, and leachate samples were analyzed for the following parameters: Analytical parameters, as specified in 310 CMR 19.132(2)(h), included: 1) Indicator parameters: a) pH (in situ) b) Alkalinity c) Temperature (in situ) d) Specific Conductance (in situ) e) Nitrate Nitrogen (as Nitrogen) f) Total Dissolved Solids g) Chloride h) Calcium i) Sodium j) Iron k) Manganese l) Sulfate m) Chemical Oxygen Demand (COD) n) Dissolved Oxygen 2) Inorganics: a) Arsenic b) Barium c) Cadmium d) Chromium e) Copper f) Cyanide g) Lead h) Mercury i) Selenium j) Silver k) Zinc 3) All of the volatile organic compounds (VOCs) included in EPA Method 8260, as well as methyl ethyl ketone (2-butanone), methyl isobutyl ketone (4-methyl-2-pentanone), acetone, and 1,4-dioxane. 4) As specified in Section B.4 of the MassDEP permit, the following analytical parameters were also included: a) Semi-volatile organic compounds (SVOCs) by EPA Method 8270C as well as 1,4-dioxane by EPA Method 8270 SIM. b) Pesticides by EPA Method 8010A c) Groundwater samples analyzed for dissolved (filtered) metals d) Leachate and surface water samples analyzed for total (unfiltered) metals POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 5 2022 Post-Closure Landfill Monitoring Report.Docx 3.1 Groundwater Sampling Activities On May 25, 2022, groundwater sampling activities were conducted at the six (6) groundwater monitoring well locations shown in the Site Map (see Figure 1-2). Resampling for dissolved metals was completed on June 2, 2022. Prior to initiating groundwater sampling activities, Mabbett personnel gauged the depth to groundwater at each monitoring well utilizing an electronic interface probe (EIP) capable of measuring the depth to non-aqueous phase liquid (NAPL) or groundwater to the nearest hundredth of a foot. As summarized in Table 3-1, the depth to groundwater measured at the six monitoring wells ranged from 0.00 feet (MW-4D) to 7.67 feet (MW-2S) below the top of the PVC well risers, which extend generally 2 to 4 feet above the surrounding ground surface. NAPL was not detected or identified at any of the six monitoring wells during the 2022 landfill monitoring program. Groundwater samples were collected from each of the six monitoring wells in accordance with U.S. Environmental Protection Agency (EPA) Region 1 Low Stress/Low Flow Protocol; each groundwater monitoring well was purged until the following field parameter indicator parameters had generally stabilized to the ranges presented in Table 3-2, or the purge time reached the EPA established 2-hour purge limit: TABLE 3-2 Summary of Groundwater Stabilization Parameters Field Parameter Stabilization Criteria Specific Conductivity 3% of range Oxidation-Reduction Potential 10% of range Dissolved Oxygen 10% of range pH 0.10 Standard pH Units Temperature 3% of range Turbidity 10% of range The parameters listed above were measured using a YSI™ 556 multi-parameter sonde. Specific conductivity (SC), oxidation-reduction potential (ORP), dissolved oxygen (DO), pH, and temperature were all measured using the YSI™ multi-parameter sonde with attached flow-through cell. Turbidity was measured using a Geotech portable turbidity meter. Following an initial groundwater purge period, measurements for these field parameters were collected and recorded on field log sheets at approximate 5-minute intervals, copies of which are provided in in Appendix C. In general, stabilization was achieved (and the well deemed ready for sampling) when all field parameters remained stable for three consecutive measurements collected at least 3 to 5 minutes apart; or when the 2-hour purge limit was reached. Once purging was complete, the pump continued to run so that groundwater samples could be collected through the dedicated tubing (before sample collection, the in-line flow-through cell was removed so samples could be collected directly from the dedicated tubing). A summary of field parameter measurements recorded at the completion of purging, immediately prior to the collection of groundwater samples, is provided on Table 3-1. Groundwater samples were collected from each of the six monitoring wells (MW-1S, MW-1D, MW-2S, MW-3S, MW-4S, and MW-4D) and placed in laboratory-supplied groundwater sample containers, stored in a cooler on ice, and submitted under appropriate chain-of-custody (COC) procedures to Alpha Analytical Laboratory (Alpha) of Westborough, Massachusetts. Laboratory-supplied trip blanks were kept with the samples collected throughout the monitoring program and were submitted for laboratory analysis of VOCs. POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 6 2022 Post-Closure Landfill Monitoring Report.Docx 3.2 Surface Water Sampling Activities Surface water sampling locations were assessed prior to sampling on May 25, 2022 to verify that sufficient surface water was present to collect samples from each of the four sampling locations (designated as SW-1, SW-2, SW-3, and SW-4) as depicted on the Site Map (Figure 1-2). Prior to sample collection, groundwater quality parameters were measured in the field utilizing a YSI™ 556 multi-parameter sonde and recorded in on field sample logs included in Appendix D. A summary of field parameters measured at each surface water sampling location prior to sample collection is provided on Table 3-1. Surface water samples were collected in accordance with EPA Surface Water Sampling Operating Procedure (SESDPROC-201-R3) effective February 28, 2013, by dipping the sample container into the surface water without disturbing the bottom. Once the appropriate laboratory-supplied surface water sample containers were filled, they were stored in an iced cooler and submitted under appropriate COC procedures to Alpha. 3.3 Leachate Sampling Activities At the time of the sampling event, leachate was characterized by Mabbett personnel as standing water at the low- lying areas at the edge of the landfill footprint; leachate sampling locations LC-1 and LC-2 are depicted on the Site Map (Figure 1-2). Prior to sample collection, groundwater quality parameters were measured in the field utilizing a YSI™ 556 multi-parameter sonde and recorded in on field sample logs included in Appendix D. Due to Site conditions and the presence of leachate pooling on the ground surface, leachate samples were collected in accordance with SESDPROC-201-R3, by dipping the sample container into the surface water without disturbing the bottom. Once the appropriate laboratory-supplied leachate sample containers were filled, they were stored in a cooler on ice and submitted under appropriate COC procedures to Alpha. POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 7 2022 Post-Closure Landfill Monitoring Report.Docx 4.0 SUMMARY OF ANALYTICAL RESULTS Groundwater analytical results were compared to the current Federal Maximum Contaminant Levels (MCLs), Massachusetts Maximum Contaminant Levels (MMCLs), EPA Secondary Maximum Contaminant Levels (SMCLs), MassDEP Office of Research and Standards Guidelines (ORSG), and Massachusetts Contingency Plan (MCP) Method 1 GW-3 standards (intended to be protective of groundwater discharging to surface water). Surface water and leachate analytical results were compared to the National Recommended Freshwater Aquatic Life Criteria (NRFALC) for chronic and acute exposures. MCP Method 1 GW-2 standards are not applicable to Site groundwater because there are no buildings within 30 feet of the landfill boundary. MCP Method 1 GW-1 standards are also not applicable to Site groundwater because there are no current or potential drinking water resource areas, as defined in 310 CMR 40.0932, within applicable distances of the landfill boundary. Discussion of the laboratory analytical results for each parameter analyzed are presented in the following sections. A copy of the laboratory analytical report for the 2022 landfill monitoring program is presented in Appendix D. 4.1 Dissolved Metals Groundwater samples collected from six monitoring wells were analyzed for dissolved (filtered) metals, as specified in the landfill permit. As summarized in Table 4-1, dissolved concentrations of select metals (which included arsenic, barium, calcium, copper, iron, lead, manganese, sodium, and zinc) were detected at concentrations in excess of the laboratory lower method detection limits in the groundwater samples collected from monitoring wells. Two dissolved metals were detected in the samples collected from MW-1S, MW-3S, and MW-4S at concentrations exceeding screening values and/or comparison standards. The following is a summary of the dissolved metals concentrations exceeding screening values and/or other comparison standards:  The concentration of dissolved iron detected in the groundwater sample collected from MW-1S (0.793 milligrams per liter [mg/L]), MW-3S (1.44 mg/L), and MW-4S (4.03 mg/L) exceeded the SMCL (0.3 mg/L).  The concentration of dissolved manganese detected in the groundwater sample collected from MW-1S (0.0707 mg/L), MW-3S (0.5322 mg/L), and MW-4S (0.7864 mg/L) exceeded the SMCL (0.05 mg/L) and/or ORSG (0.3 mg/L). 4.2 Total Metals As summarized in Table 4-1, concentrations of select total metals (which included barium, calcium, chromium, iron, lead, manganese, nickel, sodium, and zinc) were detected at concentrations in excess of the laboratory lower method detection limits in the surface water and leachate samples collected. The following is a summary of the total metal concentrations identified which exceeded the NRFALC:  Iron was detected in the surface water and leachate samples collected from SW-2 (10.5 mg/L), SW-4 (2.02 mg/L), LC-1 (8.99 mg/L) and LC-2 (2.12 mg/L) at concentrations in excess of the NRFALC for chronic exposure of 1 mg/L.  Lead was detected in the surface water sample collected from SW-2 at a concentration of 0.014 mg/L, which exceeds the NRFALC chronic exposure limit of 0.0025 mg/L. 4.3 VOCs As summarized in Table 4-2, VOCs (including 1,4-dioxane) were not detected at concentrations in excess of the laboratory lower method detection limits in the groundwater samples, surface water samples, or leachate samples, apart from acetone, which was detected at 0.0071 mg/L in leachate sample LC-2, orders of magnitude below the state MMCL (6.3 mg/L). Additionally, acetone is a common laboratory contaminant. Based on the history of non-detects for this analyte since at least 2018, this finding was likely the result of laboratory contamination. POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 8 2022 Post-Closure Landfill Monitoring Report.Docx VOCs were not identified in the trip blank submitted for laboratory analysis at concentrations exceeding the laboratory lower method detection limits. 4.4 SVOCs As summarized in Table 4-3, no SVOCs were detected at concentrations in excess of the laboratory lower method detection limits in the groundwater samples collected from any of the six monitoring wells, any of the four surface water samples, nor the two leachate sample locations. 4.5 Pesticides As summarized in Table 4-4, organochlorine pesticides were not detected at concentrations in excess of the laboratory lower method detection limits in any of the groundwater, surface water, or leachate samples collected during the monitoring event. 4.6 Conventional Water Chemistry Parameters As summarized in Table 4-4, alkalinity and dissolved oxygen were detected at select monitoring locations in surface water and leachate at concentrations that exceeded the NRFALC for acute and/or chronic exposures. Alkalinity exceedances of the 20 mg/L NRFALC for chronic exposures were identified in the surface water samples collected from SW-1 (62.0 mg/L) and SW-2 (35.7 mg/L), and the leachate samples collected from LC-1 (262 mg/L) and LC-2 (26.5 mg/L). Dissolved oxygen exceedances of the 5 mg/L NRFALC for both acute and chronic exposures were identified in the surface water samples collected from SW-1 (7.5 mg/L), SW-2 (7.0 mg/L), SW-3 (7.3 mg/L), and SW-4 (7.8 mg/L), and the leachate sample collected from location LC-2 (11 mg/L). None of the other conventional chemistry parameters (including total cyanide, alkalinity, nitrate/nitrogen, sulfate, COD, chloride, and TDS) were found to exceed the MMCLs, SMCLs, MCP Method 1 GW-3 risk assessment standards, or the NRFALC for acute or chronic exposures. POST-CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs | VA CWM HCS Landfill | Leeds, MA © 2022, Mabbett & Associates, Inc. 9 2022 Post-Closure Landfill Monitoring Report.Docx 5.0 CONCLUSIONS Based on Mabbett’s review of the 2022 landfill monitoring program sampling results, the comparison of the data generated to the applicable regulatory screening values and/or standards, and the comparison of the 2022 data to recent and historical landfill monitoring results, the identified exceedances of metals (total and dissolved) and conventional chemistry parameters (alkalinity, DO) were determined to be consistent with historical landfill monitoring results. Therefore, in accordance with 310 CMR 19.000 and the 2011 Landfill Permit, a second round of sampling and analysis is not required based on the 2022 landfill monitoring program results. Mabbett delivered an email to Mr. Thomas Speight of MassDEP on July 12, 2022 to obtain concurrence from MassDEP with respect to this conclusion. MassDEP’s response to this email is pending at the time of the submittal of this report. The next annual sampling round is planned for May 2023. Prior to the next annual sampling event, Mabbett will submit a request for modification of the permit, on behalf of VA, using a BWP SW45 application to request changes in the annual sampling program for the landfill. Based on the review of historical monitoring data, VA will propose to eliminate SVOCs and pesticides from the sampling program, since there have been few, if any, positive detections of these compounds over the past several years.

Serial_No:06162216:31 Page 3 of 191 VA NORTHAMPTON LANDFILL R2020018.002 Project Name: Project Number: Lab Number: Report Date: L2227766 06/16/22 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. 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 Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data 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. 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 Alpha Project Manager 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 Project Management at 800-624-9220 with any questions.

The samples were transported to the laboratory in coolers with ice and delivered directly from the sampling site. This is considered acceptable since the samples were in the process of cooling. L2227766-01 through -06: The analysis of Dissolved Metals was cancelled at the client's request. Volatile Organics L2227766-01 through -13: Initial calibration utilized a quadratic fit for: trans-1,3-dichloropropene In reference to question H: L2227766-01 through -13: Initial Calibration did not meet: Lowest Calibration Standard Minimum Response Factor: bromodichloromethane (0.2853), 1,4-dioxane (0.0016), cis-1,3-dichloropropene (0.243), 1,1,2-trichloroethane (0.1381), chlorodibromomethane (0.1905), 1,2-dibromoethane (0.169) Average Response Factor: 1,4-dioxane, 1,1,2-trichloroethane L2227766-01 through -13: The associated continuing calibration standard is outside the acceptance criteria for several compounds; however, it is within overall method allowances. Associated results are considered to be biased high if the %D is negative and biased low if the %D is positive. A copy of the continuing calibration standard is included as an addendum to this report. Semivolatile Organics by SIM L2227766-01 through -12, WG1644160-1, WG1644160-2, and WG1644160-3: The initial calibration utilized a quadratic fit for pentachlorophenol.

Re-analysis of the LCS yielded an unacceptable recovery for cyanide, total (30%). The LCSD recovery is acceptable; therefore, no further action was taken. The LCS/LCSD RPD is above the acceptance criteria for cyanide, total (102%). Non-MCP Related Narratives Chloride The WG1651276-4 MS recovery, performed on L2227766-08, is outside the acceptance criteria for chloride (290%); however, the associated LCS recovery is within criteria. No further action was taken. Dissolved Oxygen The WG1642963-1 Laboratory Duplicate RPD for dissolved oxygen (24%), performed on L2227766-08, is outside the acceptance criteria. The elevated RPD has been attributed to the non-homogeneous nature of the native sample.

Serial_No:06302218:51 Page 3 of 23 VA NORTHAMPTON LANDFILL R2020018.002 Project Name: Project Number: Lab Number: Report Date: L2228931 06/30/22 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. 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 Outlier Summary Report, located directly after the Case Narrative. QC information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in conjunction with the sample result, associated regulatory criteria and any associated data 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. 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 Alpha Project Manager 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 Project Management at 800-624-9220 with any questions.

APPENDIX E 2022 Post-Closure Landfill Monitoring Report.Docx APPENDIX E MassDEP Email Correspondence 1 Stephen A. Vetere From:Stephen A. Vetere Sent:Tuesday, July 12, 2022 1:29 PM To:Speight, Thomas (DEP) Cc:Michalik, Robert E.; Michael L. Bloom; Cassidy E. Way Subject:VA Northampton CWM Landfill Monitoring - Leeds, MA (Mabbett Project No. R2020018.002) Attachments:2022 VA Northampton Landfill Monitoring Results Tables.pdf; 2022 VA Northamption Landfill Historical Monitoring Results.pdf Tom, Attached please find the 2022 monitoring well, surface water, and leachate analytical results in tabular format for the VAMC Northampton (Leeds, MA) Central Western Massachusetts (CWM) Landfill. This monitoring event was conducted on May 25 and June 2, 2022 by Mabbett & Associates on behalf of the VA in accordance with the MassDEP Closure Certification Transmittal #X238231 (DSWM File #11-214-008, FMF #131329) dated September 12, 2011. In accordance with the above referenced closure certification, we have included a summary tables highlighting exceedances of applicable standards including the Massachusetts Maximum Contaminant Levels (MMCLs) including secondary MMCLs, Office of Research and Standards (ORS) Guidelines, and Massachusetts Contingency Plan (MCP) Method 1 GW-3 risk assessment standards for groundwater samples; and the acute/chronic National Recommended Freshwater Aquatic Life Criteria for surface water and leachate samples. The first attachment to this email contains the following tables: Table 4-1 Metals Table 4-2 VOCs (including 1,4-dioxane) Table 4-3 SVOCs Table 4-4 Pesticides and conventional chemistry parameters The second attachment to this email provides a summary of exceedances with a comparison to historical results from 2018 through 2021:  As shown on this table, the only exceedances of applicable standards in groundwater samples were for iron and manganese (MW-1S, MW-3S, and MW-4S). However, the concentrations detected in 2022 are generally consistent with historical measurements, therefore no resampling is recommended.  Iron was detected in surface water and leachate samples above the applicable National Recommended Freshwater Aquatic Life Criteria. However, as above the concentrations detected in 2022 were consistent with historical measurements, therefore resampling is not recommended.  Lead was detected in one surface water sample at a concentration slightly above the laboratory reporting limit, therefore resampling is not recommended.  The concentration of alkalinity detected in the samples collected from surface water locations SW-1 and SW-2 and leachate locations LC-1 and LC-2 exceeded the Freshwater Aquatic Life Criteria but were consistent with historical measurements, therefore no resampling is recommended.  The concentrations of dissolved oxygen (DO) measured in each surface water and one leachate sample (LC-2) exceeded the Freshwater Aquatic Life Criteria, however the DO levels were consistent with historical values so no resampling is recommended. There were no VOCs, SVOCs, or pesticides detected in excess of any of the screening criteria. Please provide your concurrence with our recommendations or your alternate opinion if you require resampling. 2 A third party inspection (TPI) of the landfill was performed on May 4, 2021, therefore no inspection was performed in 2022. The next TPI inspection will be completed in May 2023. We will follow up with the 2022 Annual Post-Closure Landfill Monitoring and Maintenance Report submittal on or before August 1, 2022.
