INTRODUCTION This report documents field activities and results from the September 2016 water quality and landfill gas monitoring event at Western Carolina University’s (WCU’s) closed Municipal Solid Waste Landfill (MSWLF) located in Cullowhee, North Carolina (Site) as shown on Figure 1. 1.1. Site-Specific Information Site Name: WCU Closed MSWLF Facility Permit Number: 50-01 Facility Latitude/Longitude: N 35 19’ 30” / W 83 10’ 55” Site Location Map: Figure 1 Facility Address: Monteith Gap Road Cullowhee, North Carolina Jackson County Facility Owner : Western Carolina University Attn. Mr. Roger Turk 3476 Old Cullowhee Road Cullowhee, North Carolina, 28723 (828) 227-3571 Primary Consultant: Amec Foster Wheeler Environment & Infrastructure, Inc. 1308-C Patton Avenue Asheville, North Carolina 28806 (828) 252-8130 1.2. Background Information WCU operated the MSWLF from approximately the 1960s until 1993. Jackson County also disposed of municipal solid waste at the landfill from approximately the early 1970s through the early 1980s. The landfill property is approximately 31.5 acres, approximately four acres of which contain the former landfill. The landfill was closed in accordance with the then applicable North Carolina Department of Environmental Quality (NCDEQ) closure standards (15A NCAC 13B 0.0510), and a closure letter was issued to WCU by NCDEQ on September 5, 1995. NCDEQ personnel conducted a facility audit on March 16, 2011, and determined that semi-annual water quality and landfill gas monitoring at the landfill must be performed in order for the landfill to be in compliance with the post-closure conditions identified in the 1995 closure letter. In response to the audit, a Landfill Gas Investigation Work Plan, which described the preliminary landfill gas investigation, as well as the ‘full’ landfill gas investigation, was submitted to NCDEQ on October 19, 2011, and approved by NCDEQ in a letter dated November 29, 2011. Amec Foster Wheeler Environment & Infrastructure, Inc. (Amec Foster Wheeler) conducted the preliminary landfill gas investigation in January 2012 using September 2016 Water Quality and Landfill Gas Monitoring Report November 2, 2016 WCU Closed MSWLF Amec Foster Wheeler Project 6252-15-0221 2 the existing groundwater monitoring wells. NCDEQ indicated that when funding became available to WCU from the State of North Carolina, the ‘‘full’ landfill gas investigation was to be implemented. Amec Foster Wheeler has conducted semi-annual water quality monitoring since August 2011 and conducted semi-annual landfill gas monitoring utilizing the existing groundwater monitoring wells from August 2012 to November 2015 to comply with the post-closure conditions. The ‘full’ landfill gas investigation, including the installation of eight permanent landfill gas monitoring wells, was performed in February 2016. Quarterly landfill gas monitoring is now conducted.

FIELD ACTIVITIES Amec Foster Wheeler personnel visited the Site on September 15, 2016 to conduct landfill gas monitoring and on September 21, 2016 to conduct water quality monitoring. 2.1. Landfill Gas Monitoring Amec Foster Wheeler personnel measured landfill gas at the eight landfill gas monitoring wells (LG-1, LG-2, LG-3S, LG-3D, LG-4, LG-5, LG-6 and LG-7) at the Site (Figure 2). The landfill gas monitoring wells are screened in the unsaturated zone and located between the landfill and the Site’s property boundary (Table 1). The landfill gas monitoring wells are fitted with a slip cap and ball valve to allow for measurement of potential landfill gas. A calibrated gas monitoring instrument, a Landtec GEM 2000+, was used to measure atmospheric barometric pressure, as well as the following landfill gas parameters:  Methane (percent by volume)  Oxygen (percent by volume)  Carbon dioxide (percent by volume) The initial and stabilized readings for the above parameters were measured and recorded. The Solid Waste Section’s Landfill Gas Monitoring Data Form was used to record measurements and other relevant information and is provided as Appendix A. 2.2. Water Quality Monitoring Amec Foster Wheeler personnel gauged static groundwater levels in the four monitoring wells. Water levels were referenced to the top-of-casing at the wells. Depth to water measurements and water table elevations for the monitoring wells are presented in Table 2. Monitoring wells MW-1, MW-2 and MW-4 were purged and sampled using low-flow purging, utilizing a variable-speed submersible pump and new polyethylene tubing, with the intake lowered to within five feet of the bottom of the well. The pumping rate was minimized to prevent excessive drawdown in the well and simulate the well’s recharge rate, which was monitored using an electronic water level indicator. Water quality parameters (dissolved oxygen, turbidity, oxidation-reduction potential, temperature, pH, and specific conductance) were measured using a water quality meter equipped with a flow-through cell (Table 3). Groundwater samples were collected from the monitoring wells after the water quality parameters stabilized. Low-flow purging was attempted at MW-3; however, due to an insufficient volume of groundwater in the well and a slow recharge rate, the well was purged dry several times. A groundwater sample was collected from MW-3 using a new polyethylene bailer after groundwater sufficiently recharged. The submersible pump was decontaminated by washing the pump and electrical line in an industrial detergent and distilled water solution. The pump was then rinsed in distilled water. An equipment blank, EB-1, was collected from the pump discharge by operating the pump in deionized water and pumping water into sample containers.

A surface water sample (SW-2) was collected at the approximate location depicted in Figure 2. The approximate location of surface water sample SW-1, as depicted in Figure 2, was observed to be dry. The water samples were placed in laboratory-supplied containers, labeled with sampling information, packed in an ice-chilled cooler, and shipped with appropriate chain-of- custody records via overnight delivery to Prism Analytical Laboratories (a North Carolina- accredited analytical laboratory). The samples were submitted for analysis of Appendix I volatile organic compounds (VOCs) according to EPA Method 8260 and Appendix I metals according to EPA Method 6020.

RESULTS AND DISCUSSION The results of the water quality and landfill gas monitoring event are reported in the NCDEQ Environmental Monitoring Report Form that is provided as Appendix B and summarized in the following sections. 3.1. Landfill Gas The Site landfill gas monitoring wells were tested for methane, carbon dioxide, and oxygen. Refer to the attached Landfill Gas Monitoring Data Form for the testing results. Concentrations of methane were not detected in the landfill gas monitoring wells. The regulatory limit for methane at a MSWLF property boundary is equal to the lower explosive limit of methane (15A NCAC 13B.1627 (d)). The recorded results from the eight landfill gas wells do not exceed this limit indicating that regulatory limits are not being exceeded at the Site’s property boundary. 3.2. Groundwater and Surface Water Based on topography, monitoring well MW-1 is the upgradient/background monitoring well. The groundwater analytical results were compared to the North Carolina Solid Waste Section List Groundwater Standards (SWSL Standards) from Solid Waste Environmental Monitoring Reporting Limits and Standards, dated June 13, 2011, and the North Carolina Groundwater Classification and Standards (15A NCAC 2L .0202, amended effective April 1, 2013), which includes applicable interim standards, herein referred to as the “2L Groundwater Standards.” The surface water analytical results were compared to the North Carolina Surface Water and Wetlands Standards (15A NCAC 2B, summary table, dated March 2016), herein referred to as the “Surface Water Standards.” Analytical results from the September 2016 water quality monitoring event are presented in Table 4, and historical analytical results are presented in Table 5. The laboratory analytical report and chain-of-custody record are included in Appendix C. 3.2.1. Appendix I VOCs Appendix I VOCs were not detected above the method detection limit (MDL) in the groundwater sample collected from monitoring well MW-1. Six Appendix I VOCs were detected above the MDL in the groundwater samples collected from monitoring wells MW- 2, MW-3 and MW-4. Two Appendix I VOCs (1,4-dichlorobenzene and chlorobenzene) were detected at concentrations greater than the SWSL Standard, but below the 2L Groundwater Standard, in the groundwater samples collected from monitoring wells MW-3 and MW-4. Two Appendix I VOCs, chlorobenzene and 1,4-dichlorobenzene, were detected at concentrations above their respective MDLs in the surface water sample SW-2; however, the concentrations are below their respective Surface Water Standards. September 2016 Water Quality and Landfill Gas Monitoring Report November 2, 2016 WCU Closed MSWLF Amec Foster Wheeler Project 6252-15-0221 6 3.2.2. Appendix I Metals Fifteen Appendix I metals were detected above the MDL in the groundwater samples collected from the monitoring wells, including the field duplicate sample FD-1, which was collected from MW-2. Barium was detected at concentrations that exceed the SWSL Standard in the groundwater samples collected from MW-2, MW-3 and MW-4. Cobalt was detected at a concentration that exceeds the 2L Groundwater Standard and SWSL Standard in the groundwater sample collected from MW-3. Copper was detected at a concentration that exceeds the SWSL Standard in the duplicate sample collected from MW-2. Vanadium was detected at a concentration that exceeds the 2L Groundwater Standard in the groundwater sample collected from MW-3. Zinc was detected at concentrations that exceed the SWSL Standards in the groundwater samples collected from MW-2 and MW- 3. Eleven Appendix I metals were detected above the MDL in the surface water sample collected from SW-2. Cobalt was detected at a concentration that exceeds its Surface Water Standard for Human Health. Concentrations of Appendix I metals have generally been lower than historic concentrations with less exceedances above applicable Standards since low-flow purging/sampling has been implemented. Low-flow purging/sampling techniques will continue to be used for the next semi-annual water quality monitoring event.
