March June 11, 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 March 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 March 5 and 6, 2018 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 June 11, 2019 Page 2 910-78240-03-05-01-2018-September 2018 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 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-4D), 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 90 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 Dup-1) and MW-7S with concentrations ranging from 0.970 ug/l to 1.810 ug/l. Mr. Mark Dakers June 11, 2019 Page 3 910-78240-03-05-01-2018-September 2018 These findings are consistent with arsenic 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-1S, MW-3D, MW-3S, MW-4S, MW-5D, MW-5S, MW-6D, MW-6S, MW-7D, and MW-8D with values ranging from 5.30 to 6.40 (SU). Total dissolved solids exceeded the SMCL and EPA Secondary Standard of 500 mg/l in samples collected from MW-4D (and Dup-1) and MW-7S with concentrations of 590 mg/l, and 960 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 1840 ug/l to 54,100 ug/l. Manganese exceeded the SMCL and EPA Secondary Standard of 50 ug/l in samples collected from MW-3D, MW-3S, MW-4D (and Dup-1), MW-4S, MW-5D, MW-5S, MW-7D, MW-7S and MW-8S with concentrations ranging from 53 ug/l to 2,150 ug/l. Sodium exceeded the SMCL of 20,000 ug/l in samples collected from MW-3D, MW-3S, MW- 4D, MW-4S, MW-5D, MW-7D, MW-7S and MW-8S with concentrations ranging from 27,800 ug/l to 75,500 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 2019 are generally consistent with previous measurements. The next semi-annual groundwater sampling round is scheduled for September 2019. 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 National Recommended Water Quality Criteria (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 June 11, 2019 Page 4 910-78240-03-05-01-2018-September 2018 hardness value. The hardness at surface water sampling locations SW-1, SW-2 and SW-3 were 1,780 mg/l, 526 mg/l, and 81.1 mg/l, respectively. The NRWQC was calculated for metals cadmium, copper, lead, silver and zinc. 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: Lead exceeded the hardness dependent NRWQC of 2.0 ug/l in the sample collected from SW- 3 with a concentration of 2.63 ug/l. Chloride exceeded the NRWQC of 230 mg/l in the sample collected from SW-1 with a concentration of 6,200 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 March 2019 are generally consistent with previous measurements. The next semi-annual surface water sampling round is scheduled for September 2019. Additional nitrogen and phosphorous sampling was also conducted this round at groundwater and surface water locations in response to the Town’s request for nitrogen specific sampling as it relates to water quality monitoring. These sampling results will be submitted as a separate report. 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-4D, 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 Mr. Mark Dakers June 11, 2019 Page 5 910-78240-03-05-01-2018-September 2018 (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 detected above the regulatory limit of 25% of the LEL in well location LGW-9 during this round. The final concentration in LGW-9 was 12.9% by volume, equivalent to 258% of the LEL. Probe #1 and Probe #2 were installed this round to detect gas migration around LGW-9; methane was non-detected in Probe #1 and Probe #2 was non-detect for methane. Probe #1 and Probe #2 results indicate that methane is not migrating beyond the property boundary. Exceedances at this monitoring location were sent to MassDEP within the 24-hour notification time frame. A copy of the letter sent to MassDEP is included as Appendix D. Methane was only detected in LGW-9. Methane was not detected at any other monitoring locations. Carbon dioxide was detected in all monitoring locations but LGW-8, at final concentrations ranging from 0.2% to 8.2%. Oxygen was detected in all monitoring locations at final concentrations between 8.9% and 20.9%. Hydrogen sulfide was not detected at any of the monitoring locations. VOCs were not detected at any of the monitoring locations. Prior to the October 2013 sampling round, landfill gas had been consistently detected in monitoring well LGW-9, located on the south side of the site near the compost pad. Subsequently, an adjacent compost pile to LGW-9 was removed which resulted in no landfill gas detected at LGW- 9 in sampling rounds conducted during October and December 2013. Since 2013, the compost pile has fluctuated in size; the gas results have been consistent with the fluctuations of the compost pile’s size. Mr. Mark Dakers June 11, 2019 Page 6 910-78240-03-05-01-2018-September 2018 The next quarterly sampling round will be completed in June 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.

L1908554-07: One container for the Volatile Organics - EPA 8260C analysis was received broken; however, there was adequate sample remaining to perform the requested analysis. Dissolved Metals L1908554-18: The sample has an elevated detection limit for lead due to the dilution required by the high concentrations of target and non-target elements. Solids, Total Dissolved The WG1213595-3 Laboratory Duplicate RPD (17%), performed on L1908554-14, is outside the acceptance criteria. The elevated RPD has been attributed to the non-homogeneous nature of the native sample.

From:Journeay, Patrick M. Sent:Thursday, March 07, 2019 12:19 PM To:'Mark.Dakers@state.ma.us' Cc:'Rob McNeil:'; Santoro Jr, Frederic; 'colleen.ferguson@state.ma.us' Subject:24-Hour Gas Exceedance Notification - Nantucket Landfill, Nantucket Attachments:Final Nantucket Landfill EMP Map.pdf Good morning Mark, In accordance with 310 CMR 19.132 (5) (h), CDM Smith on behalf of the Town of Nantucket hereby notify MassDEP that during landfill gas sampling on March 6, 2019, the concentration of methane gas exceeded 25% of the Lower Explosive Limit (LEL) at one landfill gas well located to the east of the landfill site. The percent of the LEL by volume detected at these locations are as follows: LGW-9 258 % LEL Probe #1 0 % LEL Probe #2 0 % LEL Landfill gas well LGW-9 is located adjacent to Massasoit Bridge Road which is an unpaved narrow path in the southeast corner of the site. LGW-9 had a methane gas exceedance of 258% LEL. Probe #1 was conducted closer to the road and fence line approximately 6-8 feet in a southern direction from LGW-9; no gas was detected in Probe #1. An additional probe, Probe #2, was conducted approximately 10-15 feet south from Probe #1; no gas was detected in Probe #2. The results of this sampling round are consistent with previous sampling rounds. The well is located near a composting pile and is approximately several hundred feet away from the active landfill, we do not believe the methane detected in this well is from the landfill cell. There are no houses or utilities in this area; it is open land with dense vegetation. Attached is a site plan showing the landfill gas monitoring locations. A report summarizing all the sampling results will be submitted in the next few weeks. Please feel free to call or email Mary Mancini at (617) 452-6635 or mancinimc@cdmsmith.com if you have any questions or require any additional information.
