(MabbettO) 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. P00001. The Post -Closure Report provides a summary of the annual environmental monitoring and the maintenance inspection completed at the Site landfill on May 4, 2021. 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: ® 2021, Mabbett & Associates, Inc. 1 June 22, 2021 Project No. R2020018.001 SAADMINA\2020018 VA CWM\001\2021 Post -Closure Landfill Monitoring Report.docx POST -CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs I VA CWM MCS Landfill I Leeds, MA 12 -inch vegetative support layer ■ 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 2021 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 2021 Post -Closure Landfill Monitoring and Maintenance Report. The purpose of the post -closure monitoring and maintenance �..J 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 K 0 2021, Mabbett & Associates, Inc. 2 June 22, 2021 Project No. R2020018.001 S:\ADMINA\2020018 VA CWM100112021 Post -Closure Landfill Monitoring Report.docx POST -CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S. Department of Veteran Affairs I VA CWM HCS Landfill I Leeds, MA 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. Accordingly, at the time of the Site reconnaissance, the VA provided, and Mabbett reviewed, a monthly inspection log prepared by VA personnel documenting the performance of monthly landfill inspections throughout the time period covered by this report. 2.2 Third Party Inspection In accordance with 310 CMR 19.143, Mr. Stephen Vetere of Mabbett, registered MassDEP Third -Party Inspector (TPI), performed the required Site reconnaissance for a TPI at the VA CWM HCS landfill. The purpose of the visit was to confirm that the VA was maintaining, caring for, and monitoring the Site during post -closure period in order to document the integrity of the closure measures and to detect and prevent any adverse impacts of the Site on public health, safety, or the environment. A copy of the TPI Report documenting the findings on the form required by the MassDEP at 310 CMR 19.018(8) is attached in Appendix B. During the inspection on May 4, 2021, Mr. Vetere observed that the landfill was in very good condition, with vegetative cover throughout the landfill and only a few minor areas with evidence of erosion along the slope of the landfill. One small area of erosion near MW -3S that was noted in previous inspections has been repaired by VA since the last inspection by replacing sand and stone that had been displaced and covering the area with new geotextile fabric. Additionally, several areas at the perimeter of the landfill where the geotextile liner had been displaced have been repaired by placing and securing new lengths of geotextile. Each monitoring well was inspected and determined to be in good, stable condition and appropriate for sampling. New concrete seals have been installed at the base of each well since the 2020 inspection. The access road to the landfill was in good condition. The landfill area's fence was locked (open for inspection) and in good condition, with appropriate signage; drainage swales were not obstructed, and the retention basin was in good condition. No landfill gas monitoring is conducted, as stated in the MassDEP approval letter from September 12, 2011. ® 2021, Mabbett & Associates, Inc. 3 June 22, 2021 Project No. R2020018.001 S:\ADMINA\2020018VA CWM\001\2021 Post -Closure Landfill Monitoring Report.docx POST -CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U,S- Department of Veteran Affairs I VA CWM HCS Landfill I Leeds, MA 3.0 ANNUAL SAMPLING a The annual landfill monitoring activities include the collection of groundwater samples from monitoring wells MW -1S, MW -1D, MW -2S, MW -3S, MW -4S, and MW -4D; collection of surface water samples from locations SW - 1, SW -2, SW -3, and SW -4; and collection of leachate samples from locations LC -1 and LC -2. A photographic log illustrating the conditions at each of the sampling locations on May 4, 2021 is included as Appendix C. 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 1) 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 a.)

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 (NAPE) 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 0.80 feet (MW -4D) to 5.61 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 2021 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 Summary ofGroundwater 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 YSITM 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 D. 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, ® 2021, Mabbett & Associates, Inc. 5 June 22, 2021 Project No. 82020018.001 S:\ADMINA\2020018 VACWM\001\2021 Post -Closure Landfill Monitoring Report.docx POST -CLOSURE LANDFILL MONITORING AND MAINTENANCE REPORT U.S- Department of Veteran Affairs I VA CWM HCS Landfill I Leeds, MA and submitted under appropriate chain -of -custody (COC) procedures to Alpha Analytical Laboratory (Alpha) of a Westborough, Massachusetts. Laboratory -supplied trip blanks were kept with the samples collected throughout the monitoring program and were submitted for laboratory analysis of VOCs. 3.2 Surface Water Sampling Activities Surface water sampling locations were assessed prior to sampling on May 4, 2021 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 YSII 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.

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 2021 landfill monitoring program is presented in Appendix E. 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 barium, calcium, iron, manganese, and sodium) 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 sample collected from 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 -4S [1.13 milligrams per liter (mg/L)] exceeded the SMCL (0.3 mg/L). ■ The concentration of dissolved manganese detected in the groundwater sample collected from MW -4S (0.398 mg/L) exceeded the SMCL (0.05 mg/L) and ORSG (0.3 mg/L). 4.2 Total Metals As summarized in Table 4-1, concentrations of select total metals (which included barium, beryllium, calcium, chromium, copper, 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 leachate samples collected from LC -1 (5.19 mg/L) and LC -2 (8.02 mg/L) at concentrations in excess of the NRFALC for chronic exposure of 1 mg/L. ■ Lead was detected in the leachate sample collected from LC -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 collected from any of the six monitoring wells, any of the four surface water samples, nor the two leachate sample locations. VOCs were not identified in the trip blank submitted for laboratory analysis at concentrations exceeding the laboratory lower method detection limits.

Department of Veteran Affairs I VA CWM HCS Landfill I Leeds, MA 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 monitoring wells MW -1D, MW -2S, and MW -4D, in surface water samples collected from SW -1, SW -3, and SW -4, and in the leachate sample collected from LC-1.Only one SVOC, dibenzo(a,h)anthracene, was detected in leachate sample LC -2 at a concentration of 0.00013 mg/L. This detected SVOC was orders of magnitude lower than its applicable screening value. 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, with the exception of hexachlorobenzene detected at groundwater monitoring well MW -4D (0.000019 mg/L). This pesticide was detected orders of magnitude lower than its applicable MMCL screening value of 0.001 mg/L. 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. Specifically, the concentration of alkalinity detected in the surface water sample collected from SW -1(23.6 mg/L) and the leachate sample collected from location LC -1(232 mg/L) exceeded the NRFALC for chronic exposure of 20 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 (6.0 mg/L), SW -2 (7.3 mg/L), SW -3 (8.2 mg/L), and SW -4 (8.0 mg/L), and the leachate sample collected from location LC -2 (7.8 mg/L). None of the other conventional chemistry parameters (including total cyanide, 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.

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 2021 landfill monitoring program results. Mabbett delivered an email to Mr. Thomas Speight of MassDEP on June 1, 2021 to obtain concurrence from MassDEP with respect to this conclusion. A copy of email correspondence from Mr. Spelght documenting the MassDEP Solid Waste Section's support that resampling was not warranted or required, is provided in Appendix F.

Inspection Observations A. FACILITY CONDITION AND OPERATIONS Examine and evaluate the facility condit-on and operations as observed during the inspection, including the following: ❑ Describe any evidence of the following conditions observed at the time of the inspection: • Unpermitted discharges to air, water, land or other natural resources of the Commonwealth; and • Dust, odors, litter, and/or other nuisance conditions. ❑ Document and discuss all deviations from any specific requirements for the facility that are not addressed in the previous section (Section V — Performance Standards), including without limitation, the requirements set forth in the facility's operation and maintenance plan, orders or other enforcement documents, and other solid waste permits, approvals, and authorizations issued to the facility by MassDEP. ❑ List the types and est'mated quantities of all waste and materials stored at the facility at the time of the inspection. ® Provide a narrative that describes the overall status of the general condition, operation and performance of the facility as observed at the time of the inspection. -*Attach photographs taken during the inspection that depict the general condition and operation of the facility. At a minimum, include photographs, as applicable, of the waste unloading (tipping) area, waste storage areas, recyclable material storage and, for transfer stations, the waste reloading activity, Discussion The VA Central Western Massachusetts Healthcare System Landfill is a closed landfill. Third Party Inspector Stephen Vetere observed the landfill to be in good condition at the time of the inspection on 5/4/2021. The entire landfill is enclosed by a chain-link fence that is in very good condition. All gates are locked (the permittee unlocked the gates to enable the inspection) and signage maintained in good condition. The vegetative cover on the landfill is in good condition, with no major areas lacking vegetation. There was no unusual settlement observed. The stormwater drainage system appeared to be functioning properly, with no excessive siltation or obstructions in any of the swales or detention basins. All monitoring wells are maintained in good condition. The area of minor erosion first noted in the 2018 inspection report near MW -3S has been repaired by the permittee since the 2020 inspection. The sand and stone that had been displaced was moved back and covered with geotextile material to provide further stability and prevent any future erosion of materials from the embankment. The permittee also replaced geotextile fabric in several areas at the toe of the landfill slope where the material had been damaged and/or displaced by the elements. Also during the past year, the permittee has installed new concrete surface seals at each of the monitoring wells. This is the sixth TPI inspection performed since the program was implemented by MassDEP. No prior corrective actions were noted in previous inspection reports. No photographs are required since this is a closed landfill facility. B. RECORD REVIEW Examine and evaluate the facility's record-keeping. Without limitation, document the status of the facility's compliance with, and any deviations from, the record-keeping required by 310 MCR 19.000; the facility's operation and maintenance plan; orders or other enforcement documents issued to the facility; and other solid waste permits, approvals, determinations and authorizations issued to the facility by the Department, including the following: ® Discuss the evaluation of the Facility's 'daily log" such as, daily tonnage records. ❑ List and discuss any special incidents that have occurred since the previous inspection such as exceedances of the facility's permitted waste acceptance limits, nature and outcome of complaints reported to the facility operator (including the identity of the complainant, if known), fires, emergencies, or other disruptions to the routine operation of the facility. Discussion: The permittee (VA) has been performing monthly inspections, which are documented on an inspection checklist.

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 (Le 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.

At the client's request, the collection date/time is reported as 04 -MAY -21 10:20. L2123071-12: The collection date and time on the chain of custody was 04 -MAY -21 10:20; however, the collection date/time on the container label was 04 -MAY -21 11:30. At the client's request, the collection dateltime is reported as 04 -MAY -21 11:30. The samples were received at the laboratory above the required temperature range. The samples were transported to the laboratory in a cooler with ice and delivered directly from the sampling site. This is considered acceptable since the samples were in the process of cooling. Volatile Organics In reference to question H: L2123071-01 through -13: Initial Calibration did not meet: Lowest Calibration Standard Minimum Response Factor: 1,4 -dioxane (0.0011) Average Response Factor: 1,4 -dioxane Verification: dichlorodifluoromethane (161%), chloromethane (139%), vinyl chloride (133%) L2123071-01 through -13: The associated continuing calibration standard is outside the acceptance criteria for several compounds; however, it is within overall method allowances. A copy of the continuing calibration standard is included as an addendum to this report. Semivolatile Organics L2123071-01 through -12 and WG1496419-1/-2/-3: The initial calibration utilized a quadratic fit for Butyl benzyl phthalate, Bis(2-ethylhexyl)phthalate, Di-n-octylphthalate.

Total Metals In reference to question G: L2123071-07 through -12: One or more of the target analytes did not achieve the requested CAM reporting limits. Non -MCP Related Narratives Dissolved Oxygen L2123071-03, -06 through -12 were analyzed with the method required holding time exceeded. Solids, Total Dissolved The WG1495599-3 Laboratory Duplicate RPD for solids, total dissolved (12%), performed on L2123071-01, is outside the acceptance criteria. The elevated RPD has been attributed to the non-homogeneous nature of the native sample. Alkalinity, Total WG1498791: A Matrix Spike and Laboratory Duplicate were prepared with the sample batch, however, the native sample was not available for reporting; therefore, the results could not be reported. 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.

Tom, Attached please find the 2021 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 4, 2021 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 2020: • As shown on this table, the only exceedances of applicable standards in groundwater samples was for iron and manganese in MW -4S. Each exceeded their secondary MMCLs. However, the concentrations detected in 2021 are generally consistent with historical measurements therefore no resampling is recommended. • Iron and lead were detected in leachate samples above their applicable National Recommended Freshwater Aquatic Life Criteria. However, as above the concentrations detected in 2021 were consistent with historical measurements, therefore resampling is not recommended. • The concentration of alkalinity detected in the sample collected from surface water location SW -1 and leachate location LC -1 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. The third party inspection (TPI) of the landfill was also performed on May 4, 2021 and the form will be submitted to you before June 4, 2021. A copy of the report will also included in our Post - Closure Landfill Monitoring and Maintenance Report submittal (on or before 6/30/20). Respectfully, Steve Stephen A.
