March November 12, 2019 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 September 2019 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 September 23rd, 24th, and 25th, 2019 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 November 12, 2019 Page 2 1910-78240-03-05-01-2019-03. September 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, copper, lead, silver and zinc) 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-3D), 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 metal’s, 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 126 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 (and DUP-1), MW-3S, MW- 4D and MW-7S with concentrations ranging from 0.746 ug/l to 3.060 ug/l. Mr. Mark Dakers November 12, 2019 Page 3 1910-78240-03-05-01-2019-03. September 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: pH was below the SML and EPA Secondary Standard minimum of 6.5 standard units (SU) in samples collected from MW-3D, MW-3S, MW-4S, MW-5D, MW-5S, MW-6D, MW-6S, MW-7D, MW-8D and MW-8S with values ranging from 5.36 to 6.39 (SU). 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 ranging from 610 mg/l, to 1,000 mg/l, respectively. Iron exceeded the SMCL and EPA Secondary Standard of 300 ug/l in samples collected from MW-3S, MW-5S, and MW-7S at concentrations ranging from 878 ug/l to 51,300 ug/l. Manganese exceeded the SMCL and EPA Secondary Standard of 50 ug/l in samples collected from MW-3D (and DUP-1), MW-3S, MW-4D, MW-4S, MW-5D, MW-5S, MW-7D, MW-7S and MW-8S with concentrations ranging from 60 ug/l to 1,720 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 21,000 ug/l to 91,200 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 September 2019 are generally consistent with previous measurements. The next semi-annual groundwater sampling round is scheduled for March 2020. Surface Water Sampling CDM Smith collected a surface water sample from monitoring locations SW-1 and SW-2. SW-3 was not sampled this round due to dry conditions. 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 Mr. Mark Dakers November 12, 2019 Page 4 1910-78240-03-05-01-2019-03. September hardness value. The hardness at surface water sampling locations SW-1 and SW-2 were 2,360 mg/l and 724 mg/l, respectively. The NRWQC was calculated for metals cadmium, chromium, Lead, Silver, Zinc, and Copper. The individual calculated criteria are shown for the sampling location on Table 4A. 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 8,500 mg/l. Table 5 summarizes results for surface water VOCs. NRWQC are not currently established for VOCs in the monitoring program. Surface water monitoring results from September 2019 are generally consistent with previous measurements. The next semi-annual surface water sampling round is scheduled for March 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-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. Gas Monitoring Post-closure landfill gas monitoring consisted of sampling 13 landfill gas wells, including LGW-1 through LGW-13. 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), using a Landtec GEM 2000 Gas Analyzer; volatile organics using an organic vapor meter (OVM), lamp eV 10.6; and hydrogen sulfide (H2S) using an Interscan1000 Meter. The following summarizes the results of the gas sampling: Methane was not detected is any of the monitoring locations during this round. Mr. Mark Dakers November 12, 2019 Page 5 1910-78240-03-05-01-2019-03. September Carbon dioxide was detected in all monitoring locations at final concentrations ranging from 0.1% to 13.3%. Oxygen was detected in all monitoring locations at final concentrations between 5.2% and 20.9%. Hydrogen sulfide was not detected at any of the monitoring locations. VOCs were not detected at any of the monitoring locations. The next quarterly gas sampling round will be completed in December 2019.

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 WG1292418-3 MS recovery for hardness (196%), performed on L1943912-11, does not apply because the sample concentration is greater than four times the spike amount added. Dissolved Metals The WG1292314-3 MS recovery for iron (20%), performed on L1943912-01, does not apply because the sample concentration is greater than four times the spike amount added. The WG1292338-3 MS recovery, performed on L1943912-11, is outside the acceptance criteria for arsenic (128%). A post digestion spike was performed and yielded an unacceptable recovery of 128%. The serial dilution recovery was not applicable; therefore, this element fails the matrix test and the result reported in the native sample should be considered estimated. The WG1292338-3 MS recoveries for calcium (160%) and sodium (1300%), performed on L1943912-11, do not apply because the sample concentrations are greater than four times the spike amounts added.

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 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. This represents an estimated concentration for Tentatively Identified Compounds (TICs), where the identification is based on a mass spectral library search. The RPD between the results for the two columns exceeds the method-specified criteria. The quality control sample exceeds the associated acceptance criteria. For DOD-related projects, LCS and/or Continuing Calibration Standard exceedences are also qualified on all associated sample results. Note: This flag is not applicable for matrix spike recoveries when the sample concentration is greater than 4x the spike added or for batch duplicate RPD when the sample concentrations are less than 5x the RL. (Metals only.) Analytical results are from sample re-analysis. Analytical results are from sample re-extraction. Analytical results are from modified screening analysis. 1 The reference for this analyte should be considered modified since this analyte is absent from the target analyte list of the original method. - Serial_No:10091922:08 Page 172 of 178 Alpha Analytical performs services with reasonable care and diligence normal to the analytical testing laboratory industry.
