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 February 22, 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-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 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 112 ug/l. Benzene exceeded the MCL and EPA Primary Standard of 5 ug/l in the sample collected from monitoring well MW-7S with a concentration of 5.3 ug/l. Mr. Mark Dakers February 22, 2019 Page 3 910-78240-03-05-01-2018-September 2018 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 1.160 ug/l to 3.230 ug/l. 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 in samples collected from MW-1S, 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 5.19 to 6.30 standard units. 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 650 mg/l, 640 mg/l and 1,100 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, MW-7D, and MW-7S at concentrations ranging from 907 ug/l to 68,900 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 MW-7S with concentrations ranging from 71 ug/l to 3,270 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 and MW-7S with concentrations ranging from 20,500 ug/l to 107,000 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 2018 are generally consistent with previous measurements. The next semi-annual groundwater sampling round is scheduled for March 2019. Mr. Mark Dakers February 22, 2019 Page 4 910-78240-03-05-01-2018-September 2018 Surface Water Sampling CDM Smith collected a surface water sample from monitoring location SW-1. SW-2 and SW-3 were both dry and samples could not be collected during this round. 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 hardness value. The hardness at surface water sampling locations SW-1 was 3,340 mg/l. 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: pH was found to be under the recommended NRWQC guideline of 6.5-9 standard units in the sample collected from SW-1 with a concentration of 6.05 standard units. Chloride exceeded the NRWQC of 230 mg/l in the sample collected from SW-1 with a concentration of 12,000 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 2018 are generally consistent with previous measurements. The next semi-annual surface water sampling round is scheduled for March 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-3D, indicating laboratory analysis was consistent. Mr. Mark Dakers February 22, 2019 Page 5 910-78240-03-05-01-2018-September 2018 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 detected at monitoring location LGW-7 with a final concentration of 8.8 % methane by volume and an LEL of 176%. Carbon dioxide was detected in all monitoring locations at final concentrations ranging from 0.2% to 30.7%. Oxygen was detected in all monitoring locations at final concentrations between 0.2% and 20.9%. Hydrogen sulfide was not detected at any of the monitoring locations. VOCs were not detected at any of the monitoring locations. 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 a non-reportable reading of 8% LEL which is far below regulatory limit of 25% LEL. Since 2013, the compost pile has fluctuated in size; the gas results have been consistent with the fluctuations of the compost pile’s size. Confirmation Probe-1 was installed to confirm landfill gas was not migrating past the property line, results from Probe-1 were non-detect during this sampling round. LGW-7 Gas well is located on the Northeast side of the landfill behind the compost facility. The area to the east of LGW-7 has been mined for sand for use in a new landfill cell. The replacement material was a mixture of cover material and raw compost material. Additional sampling was conducted to confirm if cover material is the cause of the high methane detection. First, A probe was installed next to the compost plant to see if methane is migrating toward the building. Readings were non-detect for methane. The building, utilities and drains in the area were also monitored and readings were all were non-detect for methane. Finally, additional probes (probe -5 and probe -6) were installed toward the property line to monitor the extent of methane migration. The methane is contained to the one area where this cover material has been placed and doesn’t extend past the property line (probe-4) The replacement cover material appears the source of the methane exceedance at LGW-7. Mr. Mark Dakers February 22, 2019 Page 6 910-78240-03-05-01-2018-September 2018 The next quarterly sampling round was completed on December 4, 2018.

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. All specific QC information is also incorporated in the Data Usability format of our Data Merger tool where it can be reviewed along with any associated 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. 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 table. The information is also incorporated in the Data Usability format of our Data Merger tool where it can be reviewed along with any associated usability implications. Please see the associated ADEx data file for a comparison of laboratory reporting limits that were achieved with the regulatory Numerical Standards requested on the Chain of Custody. 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 Client Service Representative 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 Client Services at 800-624-9220 with any questions.

This was verified by the client. Dissolved Metals L1838248-10: The sample has elevated detection limits for all elements, with the exception of mercury, due to the prep dilution required by the sample matrix. L1838248-13: The sample has elevated detection limits for cadmium, copper, lead, and silver due to the dilution required by the high concentrations of target and non-target elements. The WG1164757-3 MS recovery for iron (0%), performed on L1838248-01, does not apply because the sample concentration is greater than four times the spike amount added. Sulfate L1838248-01: The sample has an elevated detection limit due to the dilution required by the sample matrix.

From:Mancini, Mary Sent:Thursday, September 27, 2018 1:24 PM To:Dakers, Mark (DEP) Cc:Robert McNeil; Santoro Jr, Frederic; Journeay, Patrick M.; Ferguson, Colleen (DEP) Subject:24-hour Notification - Nantucket Attachments:Final Nantucket Landfill EMP Map (1).pdf; Figure 1 - LGW-7.pdf; IMG_1234.jpg Good afternoon Mark, In accordance with 310 CMR 19.132 (5) (h), CDM Smith on behalf of the Town of Nantucket hereby notifiy MassDEP that during landfill gas sampling on September 26, 2018, the concentration of methane gas exceeded 25% of the Lower Explosive Limit (LEL) at one landfill gas well and two probes located to the east of the landfill site. The percent of the LEL by volume detected at these locations are as follows: LGW-7 176 % LEL Probe #4 0 % LEL Probe #5 0 % LEL Probe #6 370 % LEL Probe #7 292 % LEL The active landfill is approximately 300’ away form LGW-7. The wells LGW-13, LGW-6 and LGW-5 all are closer to the landfill than LGW-7 and all came back non- detect for methane. Landfill gas well LGW-7 is located on the eastern side of the landfill behind the composting facility (See attached Figures). Exceedances in this location were first encountered and reported during the July 2017 sampling round. The area had been mined for sand to use for new cell construction on the landfill. The sand had been replaced with a reprocessed cover material that had been mined out of the landfill and stockpiled. In response to DEP’s comments in email below with respect to the June 2018 sampling round results, CDM Smith conducted further investigation into the LGW -7 landfill gas exceedance. All on site buildings and utilities were screened for methane and none was detected. To investigate the source of the methane at LGW-7, landfill gas probes were installed both between the well and the buildings and between the well and the property line. The first probe (Probe #5) was installed just outside the compost facility between the building and the LGW-7 well. This probe came back non- detect showing that gas is not migrating west toward the building. The next probe (Probe #6) was installed 10 ft away from the well east toward the property line into the reprocessed cover material. This probe came back with an exceedance of 18.5 % methane by volume and an LEL of 370 %. Another probe was installed 15 ft further east toward the property line into the cover material (Probe#7). This probe had an exceedance of 14.6 % methane by volume with an LEL of 292%. The final probe location is the location has been installed during previous rounds (Probe #4) to confirm migration is not going off site. It is at the eastern property line approximately 15 ft away from Probe #7. This probe (Probe-4) was installed 5’ from the fill material into virgin sandy soil and came back non-detect. Based on the additional probe investigations conducted, the methane detected appears to not from the landfill cell and directly due to the replacement material. The Town of Nantucket is addressing the matter with Waste Options and a response action will be reported when information is available. 2 A report summarizing all the sampling results will be submitted in the next few weeks.

However the site map indicates that the Compost plant is between the Landfill and the exceeding gas well. The purpose of the landfill gas of monitoring wells is to detect landfill gas migration before it gets to a receptor (e.g. buildings, utility conduits etc. on site or offsite) or the property line whichever is closer. For this reason, MassDEP considers landfill gas well GW-7 (and for that matter landfill gas well GW-6) point of compliance wells and therefore you should follow the procedures for a 24 hour notification. If it is believed that the concentrations of methane gas detected in LGW-7 is not from the landfill (i.e. compost material) this should be investigated but nearby subsurface utilities and structures should be evaluated as referenced below regardless. 3 In order to determine extent of landfill soil gas migration and whether the presence of landfill gas in soils poses an Imminent Threat the following should be part of your reporting: · a statement that there are no on-site utilities or structures in the vicinity (if they do exist they must be assessed – i.e. compost plant) If a soil-gas well(s)/probe(s) with an exceedance is in close proximity to buildings, structures and/or utility conduits (excluding gas control, gas recovery and leachate collection system components), then the Town shall monitor the interior of the buildings, structures and or utility conduits for landfill gas. 1. Additionally, the Town shall take all actions necessary to ensure public health and safety due to the off-site/on-site landfill gas migration. 2. Wherever there are penetrations of the foundation, the area in the immediate vicinity should be screened for combustible gases. 3. All confined spaces within all buildings should be screened for combustible gases. 4. The buildings/utility conduits should be monitored for percent methane, volatile organic compounds, oxygen and hydrogen sulfide.
