(CDM Smith) collected groundwater and surface water samples on March 30-31, 2021 and collected field analyzed landfill gas samples on March 31, 2021 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 also 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 March 2021 monitoring round. The environmental sampling locations are shown on the Site Plan included in Appendix A. Groundwater Flow During the March 2021 monitoring round, groundwater levels were recorded at the fourteen monitoring wells prior to the collection of groundwater samples from each well. A summary of the groundwater elevations from March 2021 are presented in Table 1. The tables are included in Appendix B. Groundwater elevations observed during the March 2021 monitoring round appear to be representative of seasonal average 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 March 2021. The inorganic and organic analytical sampling results are presented in Table 2 and 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) Mr. Mark Dakers August 12, 2021 Page 2 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 March 2021 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 111 µg/l which is consistent with historical results. Total nitrogen was detected in the samples collected from groundwater monitoring wells MW-1S, MW-1D, MW-4S, MW-6S, MW-6D, MW-7S, 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 0.116 mg/l (MW-1S) to 5.09 mg/l (MW-4S) 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-4D and MW-7S with concentrations ranging from 0.325 µg/l (MW-4D) to 4.94 µg/l (MW-3S). 1,4- dioxane was also detected at MW-4S and MW-7D, however, the concentrations were below the ORS Guideline. Several volatile organic compounds (VOCs) including ethyl ether and methyl-tert-butyl ether were detected at groundwater monitoring wells MW-3S; however, the concentrations of these compounds were detected below applicable standards. The concentrations of inorganic and organic compounds are consistent 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. 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 Mr. Mark Dakers August 12, 2021 Page 3 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 March 30, 2021, CDM Smith collected surface water samples from downgradient surface water monitoring locations SW-1, SW-2 and SW-3. 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. There are no established NRWQC for aquatic life for the VOC parameters sampled in this monitoring program. The surface water results are presented in Tables 4, Table 4A and Table 5 (Attachment B). At surface water sampling location SW-1, the chloride concentration (5,000 µg/l) exceeded the NRWQC of 230 µg/l. At surface water sampling location SW-2, the iron concentration (4,040 µg/l) exceeded the NRWQC of 1,000 µg/l. At surface water sampling location SW-3, the concentration of copper, lead, and zinc exceeded the hardness dependent NRWQC for each parameter. The remaining inorganic parameters were reported as non-detect or below the EPA NRWQC. At surface water sampling location SW-1 and SW-3, all VOC compounds were reported as non-detect. At surface water sampling location SW-2, 1,4-dioxane was detected at a concentration of 0.848 µg/l which is greater than the ORS Guideline and consistent with historical results. Acetone was also detected in the sample collected from SW-2 at a concentration of 8 µg/l, however, the concentration is well below the ORS Guideline of 6,300 µg/l. The detection of acetone appears to be an anomaly based on historical results and is a common lab contaminant which is discussed further below. CDM Smith will continue to closely monitor the surface water sampling results during future monitoring rounds. Surface water monitoring results from the March 2021 round 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: Mr. Mark Dakers August 12, 2021 Page 4  The duplicate sample results closely matched those of its associated sample collected at MW-3D, indicating laboratory analysis was consistent.  The trip blank sample result was non-detect, indicating that the field sample handling, storage and transport did not introduce VOC contaminants.  The field blank sample result was non-detect for all analytes except for a low-level detection of acetone (7.4 µg/l). With the exception of acetone, the field blank results indicate that the field sample handling, storage and transport did introduce contaminants. The detection of acetone appears to be a laboratory introduced contaminant. Landfill Gas Monitoring On March 31, 2021, CDM Smith sampled thirteen (13) landfill gas monitoring wells identified as LGW-1 through LGW-13 and three landfill gas probes (Probe-1 through Probe-3) for the presence of landfill gas. The landfill gas well and probe locations are shown on the Site Plan. For all landfill gas locations 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). The landfill gas well and probe locations 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 March 2021 landfill gas monitoring round. The initial reading for methane was detected at 206% of the LEL, and upon completion of purging (final), methane was detected at 68% of the LEL. Since methane was detected at LGW-9, landfill gas probe-1 through landfill gas probe-3 were installed and sampled. At landfill gas probe-1, methane was detected at 4% of the LEL in the final readings which is below the 25% LEL limit. Methane was not detected at the two remaining landfill gas probes. Landfill gas probe-1, probe-2 and probe-3 are located approximately 10 feet, 20 feet and 30 feet to the south of LGW-9, respectively. In accordance with 310 CMR 19.132(4)(h), the MassDEP Southeast Regional Office (SERO) was notified of the exceedance of the regulatory limit of 25% of the LEL at the property boundary at LGW-9 in an email dated April 2, 2021. A copy of the notification email is included in Appendix D. Hydrogen sulfide and VOCs were not detected at any of landfill gas sampling locations during this monitoring round. Carbon dioxide was detected at all landfill gas sampling locations except LGW-8. The carbon dioxide concentrations ranged from 0.3 to 7.3 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. Mr. Mark Dakers August 12, 2021 Page 5 Conclusions and Recommendations Results of the March 2021 groundwater, surface water and landfill gas monitoring are consistent with historical results. The next semi-annual monitoring round will be conducted in September 2021.

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.

From:Castonguay, Nicholas J. Sent:Friday, April 02, 2021 2:58 PM To:Dakers, Mark (DEP); Ferguson, Colleen (DEP) Cc:Robert McNeil; Graeme Durovich; Mancini, Mary; Santoro Jr, Frederic Subject:Nantucket LF - March 2021 Landfill Gas Exceedance Notification Attachments:Nantucket Landfill Environmental Monitoring Plan 3-13-13.pdf In accordance with 310 CMR 19.132(5)(h), CDM Smith on behalf of the Town of Nantucket hereby notifies MassDEP that during landfill gas monitoring on March 31, 2021, the concentration of methane gas exceeded 25% of the Lower Explosive Limit (LEL) at one landfill gas well location (LGW-9) in southeast area of the landfill property. The location of the landfill gas well locations are shown on the attached figure. The concentrations of methane and LEL measured at LGW-9 are as follows: Location Initial Methane Initial LEL Final Methane Final LEL LGW-9 10.3% 206% 3.4% 68% The LEL concentration is similar in range to previous landfill gas detections at this location. Landfill gas probes (LGP-1, LGP-2, LGP-3) located adjacent to the property line were also installed as shown on the attached figure. Methane was detected at LGP-1 below the 25% LEL limit and methane was not detected at the two remaining gas probe locations (LGP-2, LGP-3) nor any other gas sampling location during the March 2021 monitoring round. Based on this information, it appears that the detected landfill gas remains limited to a small area at the southeast corner of the landfill property adjacent to the composting pad and does not appear to be migrating off-site across Massasoit Road where LWG-9 is located.
