3 Post Closure Environmental Monitoring Report Page 1 Shawmut Avenue Landfill, New Bedford, Massachusetts May 26, INTRODUCTION On behalf of the City of New Bedford, PRIME Engineering, Inc. (PRIME) has prepared this Post Closure Environmental Monitoring Report to provide the Massachusetts Department of Environmental Protection (MassDEP) with the results of post closure landfill gas, groundwater, surface water, and sediment monitoring data collected at the Shawmut Avenue Landfill facility in May Post Closure Landfill monitoring was conducted in accordance with the Massachusetts Solid Waste Management Regulations (310 CMR 19.00) and the requirements of the facility specific Post Closure Monitoring and Maintenance Plan, which was approved by the MassDEP in a letter dated April 19, SCOPE OF WORK The following is the Scope of Work associated with the Post Closure Environmental Monitoring Event conducted in May 2016: Collection of landfill gas data at fourteen (14) existing landfill gas wells, ten (10) temporary gas probes, six (6) temporary monitoring points/vents, three (3) catch basins, and two (2) buildings; Collection of in situ groundwater data and groundwater samples from nine (9) monitoring wells; Collection of surface water samples from three (3) surface water sampling locations; Collection of one (1) sediment sample; Laboratory analysis of groundwater, surface water, and sediment samples; Evaluation of exceedences and contaminant trends; and Preparation and submission of a Post Closure Environmental Monitoring Report. The following sections include information regarding sample collection procedures, results, and an evaluation of data. 3.0 MONITORING PROCEDURE & RESULTS The following subsections include information regarding the landfill gas, groundwater, surface water, and sediment sampling procedures. 3.1 Landfill Gas Monitoring PRIME conducted landfill gas monitoring on May 4, The initial and final concentrations of PRIME ENGINEERING, INC.

4 Post Closure Environmental Monitoring Report Page 2 Shawmut Avenue Landfill, New Bedford, Massachusetts May 26, 2016 methane (CH 4 ), carbon dioxide (CO 2 ), oxygen (O 2 ), hydrogen sulfide (H 2 S), and total organic volatiles (TOV) were measured at fourteen (14) landfill gas wells (LGW 1 through LGW 14), six (6) temporary gas probes (TGP 1, TGP 2, TGP 3, TGP 4, TGP 5, and TGP 12), six (6) temporary monitoring points/vents (MP 1 through MP 6), three (3) fire hydrants (Hydrant #1 through Hydrant #3), three (3) catch basins (CB 1, CB 2, and CB 3), and two (2) building structures (scale house and warehouse building). Concentrations of CH 4, CO 2, O 2, and H 2 S were measured in the field using a Landtec GEM 5000 Plus Gas Analyzer. TOV concentrations were measured in the field using a RAE 3000 Organic Volatile Meter (OVM), which was equipped with a 10.6 ev lamp and calibrated prior to conducting screening with 100 ppmv isobutylene span gas. Temporary gas probes were installed by driving an AMS Retract A Tip to discrete depths below the ground surface. The stainless steel Retract A Tips were connected to fluoropolymer tubing, and landfill gas samples were subsequently drawn. At least two well/probe volumes of air were evacuated from landfill gas wells and temporary gas probes prior to the collection of final measurements. Landfill gas monitoring locations are displayed on Figure 2, and a summary of field measurements collected from the above referenced locations is included in Table 1. Landfill Gas Well & Temporary Gas Probe Monitoring Results: CH 4 was detected at landfill gas wells LFG 1, LFG 2, LFG 3, LFG 4, LFG 5, LFG 6, LFG 7, and LFG 8 and temporary monitoring points/vents MP 1, MP 2, MP 3, MP 4, and MP 5 at concentrations greater than the regulatory limit of 25% Lower Explosive Limit (LEL); however, landfill gas wells and temporary monitoring points/vents were not considered to be fenceline monitoring locations, since perimeter temporary gas probes were installed and screened on the same day. CO 2 was detected in landfill gas wells LGW 1, LGW 2, LGW 3, LGW 4, LGW 5, LGW 6, LGW 7, LGW 8, LGW 9 and temporary monitoring points/vents MP 1, MP 2, MP 3, MP 4, MP 5, and MP 6 at a maximum concentration of 64.1% (within monitoring point/vent MP 1). Depleted O 2 concentrations (less than 19.5%) were detected at landfill gas wells LGW 1, LGW 2, LGW 3, LGW 4, LGW 5, LGW 6, LGW 7, LGW 8 and temporary monitoring points/vents MP 1, MP 2, MP 3, MP 4, MP 5, and MP 6. H 2 S was detected in landfill gas wells LGW 1, LGW 2, LGW 3, LGW 4, LGW 5, and LGW 6 at a maximum concentration of 4 ppm (within landfill gas well LGW 6). TOVs were not detected at concentrations greater than 1.0 ppmv during this monitoring event. No elevated concentrations of TOVs, CH 4, CO 2, H 2 S, or TOVs, nor depleted concentrations PRIME ENGINEERING, INC.

5 Post Closure Environmental Monitoring Report Page 3 Shawmut Avenue Landfill, New Bedford, Massachusetts May 26, 2016 of O 2, were detected during field screening of temporary gas probes TGP 1, TGP 2, TGP 3, TGP 4, TGP 5, TGP 6, TGP 7, TGP 8, TGP 9, or TGP 10 (i.e., fenceline monitoring locations). The results of landfill gas monitoring are generally consistent with previous landfill gas well and temporary gas probe monitoring results. It should be noted that monitoring conducted during this event did not reveal the presence of explosive gases at concentrations greater than 25% of the LEL at the property line, or beyond. Notification to the MassDEP, pursuant to 310 CMR (h), was not applicable. Catch Basin, Fire Hydrant, and Indoor Air Monitoring Results: No elevated concentrations of TOVs, CH 4, CO 2, H 2 S, nor depleted concentrations of O 2, were detected during field screening conducted at catch basins, fire hydrants, or within the scale house or the warehouse buildings. The results of catch basin and indoor air screening are generally consistent with previous monitoring results. It should be noted that the nozzle caps of Hydrant #1 and Hydrant #2 were removed as part of response actions conducted in the Summer of Groundwater Monitoring, Sampling, and Laboratory Analysis PRIME personnel collected groundwater data at nine (9) perimeter groundwater monitoring wells (CDM 1S, CDM 1D, CDM 3S, CDM 3D, CDM 4S, CDM 4D, CDM 5S, CDM 5D, and CDM 6D) on May 4, Prior to initiating low flow purging, each well was gauged for groundwater level and presence/absence of non aqueous phase liquid (NAPL) using an electronic interface probe (EIP). Subsequent to gauging, PRIME personnel purged a minimum of three well volumes of groundwater from each monitoring well using peristaltic sampling pumps and dedicated polyethylene tubing. Temperature, ph, specific conductivity, oxidation reduction potential (ORP), and dissolved oxygen (DO) were measured during monitoring well purging, using a YSI 600 XL multi parameter meter. After the field parameters were observed to have stabilized, the flow through cell of the multiparameter meter was disconnected and groundwater samples were pumped directly into the sample bottles provided by the laboratory. Samples for dissolved metals analysis were field filtered using a 0.45 micron filter, and samples for VOC analysis were collected using disposable polyethylene bailers. One duplicate sample (DUP 1) was collected from monitoring well CDM 1D. Groundwater samples were submitted to Microbac Laboratory, of Dayville, Connecticut, for laboratory analysis of parameters required by a letter entitled Approval with Conditions issued by the MassDEP and dated April 19, A post sampling memorandum, including low flow PRIME ENGINEERING, INC.

6 Post Closure Environmental Monitoring Report Page 4 Shawmut Avenue Landfill, New Bedford, Massachusetts May 26, 2016 sampling logs and the complete laboratory analytical report associated with the November 2015 groundwater monitoring and sampling event, is included in Appendix A. Summarized field data and laboratory analytical results are included in Table 2. The results of laboratory analysis conducted on groundwater samples collected from perimeter monitoring wells were compared to the following standards: US EPA Maximum Contaminant Levels (MCLs) and Secondary Maximum Contaminant Levels (SMCLs); MassDEP MCLs and SMCLs; MassDEP Office of Research and Standards Guidelines (ORSG); Massachusetts Contingency Plan (MCP) Method 1 GW 2 Standards (CDM 6D only); MCP Method GW 3 Groundwater Standards. The following is a summary of exceedences and an evaluation of trends: Volatile Organic Compounds: Cis 1,2 Dichloroethylene was detected at concentrations greater than the MassDEP MCL in the groundwater sample collected from monitoring well CDM 3D. Trichloroethylene (TCE) was detected at concentrations greater than the MCL in the groundwater sample collected from monitoring well CDM 3D. Vinyl Chloride (VC) was detected at a concentration greater than the MCL in the groundwater sample collected from monitoring well CDM 4D. Chlorobenzene was detected at a concentration greater than the MCL in the groundwater sample collected from monitoring well CDM 4D. 1,4 Dioxane was detected at concentrations greater than the MassDEP ORSG Standards in groundwater samples collected from monitoring wells CDM 4S and CDM 4D. These results are generally consistent with the results of previous groundwater sampling rounds. Inorganic Parameters and Dissolved Metals: ph was outside of the SMCL, as measured at monitoring wells CDM 1S, CDM 5S, CDM 5D, and CDM 6D. Chloride was detected at a concentration greater than the SMCL in the groundwater sample collected from monitoring wells CDM 1S and CDM 4S. Total Dissolved Solids (TDS) were detected at a concentration greater than the SMCL in the PRIME ENGINEERING, INC.

7 Post Closure Environmental Monitoring Report Page 5 Shawmut Avenue Landfill, New Bedford, Massachusetts May 26, 2016 groundwater samples collected from monitoring wells CDM 1S, CDM 1D, CDM 3S, CDM 4S, CDM 4D, CDM 5S, and CDM 5D. Dissolved Iron and Manganese were detected at concentrations greater than the SMCLs in groundwater samples collected from monitoring wells CDM 1S, CDM 1D, CDM 3S, CDM 4S, CDM 4D, CDM 5S, and/or CDM 5D. Dissolved Sodium was detected at concentrations greater than the ORSG in groundwater samples collected from all monitoring wells. These results are generally consistent with the results of previous groundwater sampling rounds. PCBs: No PCB analytes were detected at concentrations greater than the analytical method detection limit (i.e., non detect). These results are generally consistent with the results of previous groundwater sampling rounds. Quality Control Sample: PRIME personnel collected a duplicate sample of groundwater from monitoring well CDM 1D. The results of laboratory analyses conducted on the duplicate sample (DUP 1) closely matched the results of analyses conducted on the original sample (CDM 1D). A field blank (de ionized water) was collected during the sample collection process. The results of VOC analysis conducted on the field blank sample did not reveal the presence of VOCs at concentrations greater than the analytical method detection limit. 3.3 Surface Water Sampling and Laboratory Analysis PRIME personnel collected surface water samples from three (3) surface water sampling locations (SW 1, SW 2, and SW 3) on May 5, Temperature, ph, specific conductivity, and dissolved oxygen (DO) were measured at the surface water sampling locations using an in situ multiparameter meter. Surface water samples were submitted to Microbac Laboratory for laboratory analysis of parameters required by a letter entitled Approval with Conditions issued by the MassDEP and dated April 19, The complete laboratory analytical report associated with the May 5, 2016 surface water sampling event is included in Appendix A, and summarized laboratory analytical results are included in Table 3. In accordance with the requirements of 310 CMR 19.00, the results of laboratory analyses PRIME ENGINEERING, INC.

8 Post Closure Environmental Monitoring Report Page 6 Shawmut Avenue Landfill, New Bedford, Massachusetts May 26, 2016 conducted on surface water samples have been compared to the established National Recommended Water Quality Criteria (NRWQC) for each parameter. The NRWQC for certain hardness dependent metals analytes (cadmium, copper, lead, and zinc) was calculated in accordance with Appendix B of the NRWQC Guideline (2009). The following is an evaluation of the results of laboratory analysis conducted on surface water samples in comparison to the NRWQC: Volatile Organic Compounds: No VOC analytes were detected at concentrations greater than the analytical method detection limits. Inorganic Parameters and Dissolved Metals: Alkalinity was detected at concentrations greater than the NRWQC in surface water samples collected at SW 1, SW 2, and SW 3. PCBs: PCBs were not detected at concentrations greater than the analytical method detection limit. These results are generally consistent with the results of previous surface water sampling rounds. 3.4 Sediment Sampling and Laboratory Analysis PRIME personnel collected one (1) sediment sample (SED 1) on May 9, The sediment sample was submitted to Microbac Laboratory for laboratory analysis of polychlorinated biphenyls (PCBs), as specified in a letter entitled Approval with Conditions issued by the MassDEP and dated April 19, The complete laboratory analytical report associated with the May 9, 2016 sediment sampling event is included in Appendix A. Summarized laboratory analytical results are included in Table 4. PCBs: One (1) PCB analyte (Aroclor 1254) was detected in the sediment sample; however, at a concentration significantly lower than the MCP Method 1 S 1/GW 3 Soil Standard. This result is generally consistent with the results of previous sediment sampling rounds. PRIME ENGINEERING, INC.
