(CDM Smith) collected groundwater and surface water samples on September 14-15, 2020 and collected field analyzed landfill gas samples on September 16, 2020 at the Nantucket Landfill located on Madaket Road in Nantucket, Massachusetts. The semi- annual water quality sampling and quarterly landfill gas sampling was conducted to satisfy the monitoring requirements of the Massachusetts Solid Waste Management Regulations (310 CMR 19.132). Sampling was conducted in accordance with the Environmental Monitoring Plan (EMP) for the Nantucket Landfill, prepared by SECOR International Inc. in July 1999. This report presents the results of the September 2020 monitoring round. Groundwater monitoring well sampling, surface water sampling and landfill gas probe sampling locations are shown on the Site Plan included in Appendix A. Groundwater Flow During the September 2020 monitoring round, groundwater levels were recorded at the fourteen groundwater monitoring wells prior to the collection of groundwater samples from each well. A summary of the groundwater elevations from September 2020 are presented in Table 1. The tables are included in Appendix B. Groundwater elevations observed during the September 2020 monitoring round appear to be representative of seasonal low groundwater conditions and are consistent with historical groundwater elevations. Overall, groundwater flow appears to be in a westerly direction towards the wetlands and Long Pond area located west of the landfill. Groundwater Monitoring Results The following discussion summarizes the results of groundwater quality monitoring completed in September 2020. The inorganic and organic analytical sampling results are presented in Table 2 and Mr. Mark Dakers December 18, 2020 Page 2 Table 3 (included in Appendix B), respectively. The laboratory analytical report is included in Appendix C. Groundwater sample results are compared to the United States Environmental Protection Agency (EPA) and MassDEP drinking water standards relative to Maximum Contaminant Levels (MCLs), Secondary Maximum Contaminant Levels (SMCLs) and MassDEP Office of Research and Standards Drinking Water Guidelines (ORS Guidelines) with exceedances noted on the tables. SMCLs are established for aesthetics and taste of a public drinking water supply and are not health-based standards. CDM Smith collected groundwater samples from the seven monitoring well couplets identified as MW- 1S/1D, MW-3S/3D, MW-4S/4D, MW-5S/5D, MW-6S/6D, MW-7S/7D and MW-8S/8D during the September 2020 monitoring round. Wells were purged five well volumes using a submersible pump prior to sampling. Initial and final groundwater quality parameters including temperature, specific conductance, dissolved oxygen, pH, and oxidation-reduction potential were monitored and recorded using a multi-parameter probe during the purge of the wells. Samples analyzed for dissolved metals were field filtered using a 0.45-micron filter. The groundwater samples were delivered to Alpha Analytical of Westborough, Massachusetts for laboratory analysis. The concentration of dissolved arsenic exceeded the MCL and EPA Drinking Water Standard of 10 micrograms per liter (µg/l) in the sample collected from MW-7S at a concentration of 126 µg/l which is consistent with historical results. Total nitrogen was detected in the samples collected from groundwater monitoring wells MW-1D, MW-4S, MW-5S, MW-6S, MW-6D, MW-8S and MW-8D with concentrations below the MCL and EPA Drinking Water Standard of 10 milligrams per limit (mg/l). The total nitrogen concentrations ranged from 0.112 mg/l (MW-8S) to 3.5 mg/l (MW-6S) and are consistent with historical results. The concentration of 1,4-dioxane exceeded the ORS Guideline of 0.3 µg/l in samples MW-3S, MW-3D, MW-4S, MW-4D and MW-7S with concentrations ranging from 0.431 µg/l (MW-4D) to 4.010 µg/l (MW- 3S). Several volatile organic compounds (VOCs) including acetone, ethyl ether and methyl-tert-butyl ether were detected at groundwater monitoring wells MW-3S and MW-7S; however, the concentrations of these compounds were all detected below applicable standards. The concentrations of inorganic and organic compounds are consistent with the most recent annual sampling round in March 2020 and historical results. The concentrations of landfill indicator parameters including manganese, sodium, iron, chloride, and total dissolved solids at the downgradient monitoring well locations are consistent with historical results and continue to be detected at concentrations greater than secondary drinking water standards. Secondary standards are established for aesthetics and taste of a public drinking supply and are not health-based. These parameters are often associated with leachate emanating from municipal solid waste landfills. Mr. Mark Dakers December 18, 2020 Page 3 Although all aquifers located on Nantucket including the area of the landfill are considered potentially productive aquifers (potential drinking water source area) and thus would be categorized as GW-1, the landfill is not located within a current drinking water source area including any private drinking water wells within 500 feet of the landfill. In consideration of these factors including the recent groundwater sampling results, no additional sampling prior to the next semi-annual monitoring round is required. Any groundwater exceedances are similar-to those known to exist at the landfill based on previous monitoring rounds. Surface Water Sampling On September 15, 2020, CDM Smith collected a surface water sample from downgradient surface water monitoring location SW-1. Surface sampling locations SW-2 and SW-3 were not sampled this round due to the dry conditions. The surface water sample was collected using a dipper. Field parameters were monitored and recorded using a multi-parameter probe. Dissolved metal samples were field filtered using 0.45-micron in-line filters in combination with a bailer. The surface water sample results were compared to EPA National Recommended Water Quality Criteria (NRWQC) for Aquatic Life (freshwater). Hardness-dependent NRWQC were calculated for cadmium, chromium, lead, silver, and zinc at all surface water sample locations using laboratory hardness results and the EPA’s equation for freshwater hardness-dependent dissolved metals (Appendix B of NRWQC). Copper criteria was calculated using the 2007 EPA freshwater biotic ligand model (BLM) as per the NRWQC. The surface water results are presented in Tables 4 and 5 (Attachment B). The chloride concentration in the surface water sample collected from SW-1 (13,000 µg/l) exceeded the NRWQC of 230 µg/l. The remaining inorganic parameters were reported as non-detect or below the EPA NRWQC. There are no established NRWQC for aquatic life for the VOC parameters sampled in this monitoring program. VOCs were not detected in the sample collected from SW-1 during this monitoring round. Surface water monitoring results from the September 2020 are consistent with historical results. Quality Control Samples Quality control samples are collected to verify that laboratory and sampling procedures are consistent and to indicate any possible cross contamination and resulting false positive analysis results. The following summarize the results of the quality control samples collected during this sampling round:  The duplicate sample results closely matched those of its associated sample collected at MW-3D, indicating laboratory analysis was consistent.  The field blank and trip blank sample result was non-detect, indicating that the field sample handling, storage and transport did not introduce contaminants. Mr. Mark Dakers December 18, 2020 Page 4 Landfill Gas Monitoring On September 16, 2020, CDM Smith sampled thirteen (13) landfill gas monitoring wells identified as LGW-1 through LGW-13 including one landfill gas probe identified as Probe-1 for the presence of landfill gas. The landfill gas probe locations are shown on the Site Plan. For all landfill gas probes sampled, concentrations of methane (CH4), carbon dioxide (CO2), oxygen (O2), hydrogen sulfide (H2S), and atmospheric pressure were obtained using a Landtec GEM 5000 Gas Analyzer. The lower explosive limit (LEL) for methane was calculated based on the methane concentration reading from the GEM 5000. VOC concentrations were obtained using a photoionization detector (PID). Temporary landfill gas probes were purged for 10 minutes with the Landtec Gas Analyzer prior to collection of final readings. The results of the landfill perimeter gas monitoring are summarized in Table 6. Methane was not detected at any landfill gas well except for LGW-9 during the September 2020 landfill gas monitoring round. At the start (initial), methane was detected at 4% of the LEL and upon completion of purging (final), methane was not detected at LGW-9. Since methane was detected in the initial reading at LGW-9, landfill gas probe-1 was installed and sampled approximately 10 feet to the south of LGW-9. Methane was not detected at landfill gas probe-1. Although methane was detected at LGW-9, it was below the LEL limit of 25%. Therefore, notification was not required to the MassDEP Southeast Regional Office (SERO) Solid Waste Management Division. Hydrogen sulfide and VOCs were not detected at any landfill gas sampling locations during this monitoring round. Carbon dioxide was detected at all landfill gas sampling locations, with concentrations ranging from 0.1 to 11.7 percent volume. The results suggest that landfill gas is not migrating off-site including the area adjacent to Massasoit Road where LWG-9 is located. Conclusions and Recommendations Results of the September 2020 groundwater, surface water and landfill gas monitoring are consistent with historical results. The next semi-annual monitoring round will be conducted in March 2021 and quarterly landfill gas monitoring round was recently completed in early December 2020.

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 WG1414602-3 MS recoveries for calcium (200%) and sodium (3100%), performed on L2038265-18, do not apply because the sample concentrations are greater than four times the spike amounts added. The WG1414602-3 MS recoveries, performed on L2038265-18, are outside the acceptance criteria for arsenic (128%), and silver (0%). A post digestion spike was performed and was within acceptance criteria. Phosphorus, Soluble L2038265-05: The Soluble Phosphorus result is slightly higher than the Total Phosphorus result. The difference is within % RPD limits; therefore, no further action was taken. Nitrogen, Total Kjeldahl The WG1410324-4 MS recovery, performed on L2038265-03, is outside the acceptance criteria for nitrogen, total kjeldahl (76%); however, the associated LCS recovery is within criteria. No further action was taken. Nitrogen, Nitrate The WG1410378-4 MS recovery, performed on L2038265-04, is outside the acceptance criteria for nitrogen, nitrate (59%); however, the associated LCS recovery is within criteria. No further action was taken. Chloride The WG1411515-4 MS recovery for chloride (0%), performed on L2038265-18, does not apply because the sample concentration is greater than four times the spike amount added. Solids, Total Dissolved The WG1410889-3 Laboratory Duplicate RPD for solids, total dissolved (11%), performed on L2038265-12, is Serial_No:09302021:26 Page 4 of 195 Case Narrative (continued) NANTUCKET LF 1910- Project Name: Project Number: Lab Number: Report Date: L2038265 09/30/20 outside the acceptance criteria. The elevated RPD has been attributed to the non-homogeneous nature of the native sample.

The analyte was detected above the reporting limit in the associated method blank. Flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For MCP-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For DOD-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank AND the analyte was detected above one-half the reporting limit (or above the reporting limit for common lab contaminants) in the associated method blank. For NJ- Air-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte above the reporting limit. For NJ-related projects (excluding Air), flag only applies to associated field samples that have detectable concentrations of the analyte, which was detected above the reporting limit in the associated method blank or above five times the reporting limit for common lab contaminants (Phthalates, Acetone, Methylene Chloride, 2-Butanone). Co-elution: The target analyte co-elutes with a known lab standard (i.e. surrogate, internal standards, etc.) for co-extracted analyses. Concentration of analyte was quantified from diluted analysis. Flag only applies to field samples that have detectable concentrations of the analyte. Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument. The ratio of quantifier ion response to qualifier ion response falls outside of the laboratory criteria. Results are considered to be an estimated maximum concentration. The concentration may be biased high due to matrix interferences (i.e, co-elution) with non-target compound(s). The result should be considered estimated. The analysis of pH was performed beyond the regulatory-required holding time of 15 minutes from the time of sample collection. The lower value for the two columns has been reported due to obvious interference. Estimated value. This represents an estimated concentration for Tentatively Identified Compounds (TICs). Reporting Limit (RL) exceeds the MCP CAM Reporting Limit for this analyte. Not detected at the reporting limit (RL) for the sample. Presumptive evidence of compound.
