March May 15, 2020 Mr. Mark Dakers Massachusetts Department of Environmental Protection Southeast Regional Office 20 Riverside Drive Lakeville, Massachusetts 02347 Subject: Summary of Groundwater, Surface Water and Gas Sampling March 2020 Nantucket Landfill Nantucket, Massachusetts Dear Mr. Dakers: On behalf of the Town of Nantucket, CDM Smith personnel collected groundwater and surface water samples and field analyzed landfill gas samples on March 9rd, 10th, and 11th, 2020 at the Nantucket Landfill in Nantucket, Massachusetts. The sampling was performed in accordance with the Massachusetts Solid Waste Management Regulations (310 CMR 19.132) and the approved Environmental Monitoring Plan, prepared by SECOR International Inc. in July 1999 for the landfill. All aqueous samples were delivered to Alpha Analytical Laboratories, Inc., in Westborough, Massachusetts for analysis. This report contains the following: Appendix A contains a site plan which shows each sampling location. Appendix B contains Tables 1 through 6 which summarize field and laboratory sampling results. Tables 1 through 6 specifically contain the following: ▪ Table 1 summarizes the groundwater levels measured at each groundwater monitoring well. ▪ Table 2 summarizes the groundwater analytical results for indicator parameters (alkalinity, chloride, chemical oxygen demand (COD), cyanide, nitrate-nitrogen, sulfate and total dissolved solids (TDS)); dissolved metals (arsenic, barium, cadmium, calcium, chromium, copper, iron, lead, manganese, mercury, selenium, silver, sodium and zinc); and parameters measured in the field (temperature, specific conductivity, dissolved oxygen and pH). ▪ Table 3 summarizes the analytical results of Volatile Organic Compounds (VOCs) for groundwater samples. Mr. Mark Dakers May 15, 2020 Page 2 1910-78240-03-05-01-2020-01. March ▪ Table 4 summarizes the surface water analytical results for indicator parameters (alkalinity, chloride, chemical oxygen demand (COD), cyanide, nitrate-nitrogen, sulfate and total dissolved solids (TDS)); measured hardness; dissolved metals (arsenic, barium, cadmium, calcium, chromium, copper, iron, lead, manganese, mercury, selenium, silver, sodium and zinc); and parameters measured in the field (temperature, specific conductivity, dissolved oxygen and pH). ▪ Table 4A summarizes the calculated National Recommended Water Quality Criteria (NRWQC) and analytical results for the hardness dependent metals (cadmium, lead, silver and zinc) and copper, which is calculated using the 2007 EPA Biotic Ligand Mofrl for surface water samples. ▪ Table 5 summarizes the analytical results of volatile organic compounds (VOCs) for surface water samples. ▪ Table 6 summarizes the results of landfill gas monitoring. Analytical results that meet or exceed applicable standards appear shaded gray in each table. Appendix C contains a copy of the laboratory data report from Alpha Analytical, Inc. The results of this sampling event are discussed below. Groundwater Sampling CDM Smith collected groundwater samples from monitoring wells MW-1S, MW-1D, MW-3S, MW- 3D, MW-4D, MW-4S, MW-5S, MW-5D, MW-6S, MW-6D, MW-7S, MW-7D, MW-8S and MW-8D. A duplicate sample (collected from MW-7D), a field blank and a trip blank were analyzed for quality assurance/quality control purposes. Wells were purged five well volumes using a submersible pump prior to sampling. Samples for dissolved metals were field-filtered using a 0.45-micron filter. Groundwater generally flows east to west across the site. The Massachusetts Solid Waste Management Regulations (310 CMR 19.132) require that sampling results be compared to the established Federal EPA Drinking Water Standards and the State Primary Maximum Contaminant Level (MCL) and Secondary Maximum Contaminant Level (SMCL) standards for each parameter. Table 2 presents the groundwater results for dissolved metals, field parameters and indicator parameters and Table 3 presents the groundwater results for Volatile Organic Compounds (VOCs). MCLs and/or EPA Primary Standards were exceeded in the following groundwater samples: ▪ Arsenic exceeded the MCL and EPA Primary Standard of 10 ug/l in the sample collected from monitoring well MW-7S with a concentration of 115 ug/l. ▪ 1,4-Dioxane exceeded the Massachusetts Contingency Plan (MCP) GW-1 Standard and drinking water SMCL of 0.3 ug/l in samples collected from MW-3D, MW-3S, MW-4D and MW- 7S with concentrations ranging from 0.487 ug/l to 2.710 ug/l. Mr. Mark Dakers May 15, 2020 Page 3 1910-78240-03-05-01-2020-01. March These findings are consistent with arsenic and 1,4-Dioxane concentrations detected during previous sampling rounds at this site. Although all aquifers located on Nantucket are considered potentially productive aquifers and thus are governed by GW-1 standards, there are currently no private drinking water wells in the area nor are there buildings located within 30 feet of any on-site monitoring wells. Due to these factors, the surface water protection criteria (GW-3) would suffice at this site. Since the Massachusetts Contingency Plan (MCP) GW-3 criteria for arsenic and 1,4- Dioxane are 900 ug/l and 50,000 ug/l, respectively, no supplemental sampling is recommended at this time. SMCLs and/or EPA Secondary Standards were exceeded in the following groundwater samples: ▪ Total dissolved solids exceeded the SMCL and EPA Secondary Standard of 500 mg/l in samples collected from MW-3S, MW-4D and MW-7S with concentrations of 610 mg/l, 540 mg/l and 980 mg/l, respectively. ▪ Iron exceeded the SMCL and EPA Secondary Standard of 300 ug/l in samples collected from MW-3S, MW-4S, MW-5S, and MW-7S at concentrations ranging from 783ug/l to 47,700 ug/l. ▪ Manganese exceeded the SMCL and EPA Secondary Standard of 50 ug/l in samples collected from MW-3D, MW-3S, MW-4D, MW-4S, MW-5D, MW-5S, MW-7D (and DUP-1), and MW-7S with concentrations ranging from 71 ug/l to 1,730 ug/l. ▪ Sodium exceeded the SMCL of 20,000 ug/l in all samples collected except MW-5S, MW-6S, and MW-8D with concentrations ranging from 21,500 ug/l to 85,600 ug/l. Secondary standards are established for the aesthetics and taste of a public drinking supply and are not health-based. Groundwater sampling results from March 2020 are generally consistent with previous measurements. The next semi-annual groundwater sampling round is scheduled for September 2020. Surface Water Sampling CDM Smith collected a surface water sample from monitoring locations SW-1, SW-2, and SW-3. The sample for dissolved metals analysis was field-filtered using a 0.45-micron filter. The Massachusetts Solid Waste Management Regulations (310 CMR 19.132) require that sampling results be compared to established NRWQC for each parameter. Hardness is a factor of the NRWQC for certain metals. If hardness at a surface water sample location varies from the standard of 100 mg/l, the NRWQC must be calculated using the measured hardness value. The hardness at surface water sampling locations SW-1, SW-2, and SW-3 were 2,010 mg/l , 405 mg/l, and 169 mg/l, respectively. The NRWQC was calculated for cadmium, chromium, lead, silver, and zinc. The criteria for copper was calculated using location specific historical data with the 2007 EPA Biotic Ligand Model. The individual calculated criteria are shown for the sampling location on Table 4A. Mr. Mark Dakers May 15, 2020 Page 4 1910-78240-03-05-01-2020-01. March Table 4 summarizes results for the field measured parameters, indicator parameters and dissolved metals. The NRWQC were exceeded in the following samples: ▪ Chloride exceeded the NRWQC of 230 mg/l in the sample collected from SW-1 with a concentration of 7,600 mg/l. Table 5 summarizes results for surface water VOCs. NRWQC are not currently established for VOCs in the monitoring program. No VOCs were detected in surface water samples from the March 2020 sampling event. Surface water monitoring results from March 2020 are generally consistent with previous measurements. The next semi-annual surface water sampling round is scheduled for September 2020. 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 taken at MW-7D, 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. Gas Monitoring Post-closure landfill gas monitoring consisted of sampling 13 landfill gas wells, including LGW-1 through LGW-13 as well as one soil gas probe, Probe-1. All gas monitoring locations are shown on the attached site plan. Each well was sampled for methane (CH4) in percent volume and lower explosive limit (LEL), carbon dioxide (CO2), oxygen (O2), hydrogen sulfide (H2S) using a Landtec GEM 5000 Gas Analyzer; volatile organics using an organic vapor meter (OVM), lamp eV 10.6. The following summarizes the results of the gas sampling: ▪ Methane was not detected is any of the monitoring locations during this round except for LGW-9 during the initial reading. However, methane was well below the regulatory limit of 25% of the LEL and was not detected in the final reading after purging. ▪ Carbon dioxide was detected in all monitoring locations except for LGW-8 with final concentrations ranging from 0.1% to 6.7%. Mr. Mark Dakers May 15, 2020 Page 5 1910-78240-03-05-01-2020-01. March ▪ Oxygen was detected in all monitoring locations at final concentrations between 12.1% and 20.9%. ▪ Hydrogen sulfide was not detected at any of the monitoring locations. ▪ VOCs were only detected in the initial reading at LGW-9. VOCs were not detected in the final reading after purging or in any other gas monitoring location. The next quarterly gas sampling round will be completed in June 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. Serial_No:03252016:16 Page 3 of 202 Case Narrative (continued) NANTUCKET LF 1910-230925-CQ-SAMP Project Name: Project Number: Lab Number: Report Date: L2010560 03/25/20 Dissolved Metals L2010560-10: The sample has elevated detection limits for all elements analyzed by method 6020B due to the dilution required by the high concentrations of non-target elements. The WG1350358-3 MS recoveries, performed on L2010560-10, are outside the acceptance criteria for arsenic (141%), selenium (138%), and silver (131%). A post digestion spike was performed and was within acceptance criteria. The WG1350358-3 MS recoveries for calcium (130%) and sodium (0%), performed on L2010560-10, do not apply because the sample concentrations are greater than four times the spike amounts added. Phosphorus, Soluble L2010560-03: The Soluble Phosphorus result is slightly higher than the Total Phosphorus result. The difference is within % RPD limits; therefore, no further action was taken. Chloride The WG1349772-4 MS recovery for chloride (0%), performed on L2010560-10, does not apply because the sample concentration is greater than four times the spike amount added. The WG1350069-4 MS recovery, performed on L2010560-13, is outside the acceptance criteria for chloride (0%); however, the associated LCS recovery is within criteria. No further action was taken. Solids, Total Dissolved The WG1350029-3 Laboratory Duplicate RPD for solids, total dissolved (13%), performed on L2010560-13, is outside the acceptance criteria. The elevated RPD has been attributed to the non-homogeneous nature of the native sample.
