Tables 1 through 3 (shown below) summarize the NC Appendix I constituents that were detected at concentrations above their respective Solid Waste Section Reporting Limits (SWSLs) and NC 2L Groundwater Standards or Solid Waste Section Groundwater Protection Standards (SWS GPSs) during the second semi-annual water quality monitoring event of 2017 conducted at the closed unlined landfill, the closed Subtitle D landfill, and the active Subtitle D landfill at the above-referenced facility between September 11 - 14, 2017, and a verification sampling event at the Active Subtitle D landfill on December 20, 2017. The laboratory certificates-of-analyses are submitted under separate cover. It is noted that the Closed Unlined Landfill is in corrective action for volatile organic compounds (VOCs); therefore no notifications for groundwater standard exceedances for VOCs are required for this facility.
