(CDM Smith), on behalf of Wake County (County), is submitting an electronic copy of the September 2017 semi-annual sampling event report for the North Wake Subtitle D Landfill (site). This letter report presents the results of the most recent semi-annual sampling event and constitutes the second semi-annual sampling event for 2017. The approved groundwater monitoring network consists of two background wells (i.e. MW-11 and -11D), 16 downgradient compliance wells (i.e. MW- 12, -12D, -13, -14, -15, -15d, -16, -17, -17D, -18, -19, -20, -21, -25, -25d, and -26), and three surface water sample locations (i.e. SW-4, -5, and -6). Field activities and sampling results are discussed below. Field Activities Groundwater samples from the North Wake Subtitle D Landfill were collected September 12, 13, 15, and 22, 2017. All samples were collected by use of disposable, laboratory decontaminated bailers. Monitoring well and surface water sampling locations are presented on Figure 1. Well construction details are provided in Table 1. Groundwater elevations were measured at each well prior to sampling and are presented in Table 2. These groundwater elevations were used to construct potentiometric contours for this sampling event and are presented on Figure 1. The groundwater elevations and potentiometric contours were used to estimate the groundwater velocity at each well. Groundwater velocity values are provided in Table 3. After depth to groundwater was determined, three well volumes of water were removed from each well prior to sampling to provide fresh formation water within the well water column. Each well volume was measured in the field for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-reduction potential using a YSI-556 multi-parameter water quality meter and a HANNA HI Ms. Jaclynne Drummond October 31, 2017 Page 2 98703 turbidity meter. Wells that had elevated turbidity were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are presented in Table 2. Sampling Results Shealy Environmental Services, Inc. located in West Columbia, South Carolina, analyzed the groundwater and surface water samples for the North Carolina Appendix I volatile organic compounds and metals. In accordance with Solid Waste Section (SWS) guidelines the analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below SWS Limits (SWSLs). All monitoring wells and surface water sample locations for the Subtitle D Landfill had detections of analytes above the MDL with a majority of the detections below SWSLs. These detections were qualified as estimated or “J” flags. The following list indicates the analytes detected above the MDL at each sampling location. No “J” flag detections are provided. Underlined groundwater analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Standard or Groundwater Protection Standard. Underlined surface water analytes exceeded the 15A NCAC 02B or Protective Value Surface Water Quality Standard for Class C Waters. A complete summary of all detected and estimated concentrations from the March 2011 to September 2017 sampling events is provided in Table 4. Laboratory analytical data reports are provided in Appendix A.

The “J” flag constituents above the standards along with their locations are listed below. Cobalt: MW-20, -25, -25D, and -26 Thallium: MW-16 Vanadium: MW-11, -11d, -12, -12D, -15, -15D, -17, -17D, -18, -19, -21, -25, and -26 Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for quality control. Barium and vanadium were reported as estimated detections in the equipment blank. Barium was detected below the NC 2L Standard and vanadium was detected above the NC 2L Standard. No analytes were detected in the trip blank above the MDL. The duplicate sampled, identified as Dup, was collected from MW-13 and had similar analyte concentrations as those detected in MW-13, with the exception of estimated detections of antimony and lead in the parent sample. Table 5 presents a summary of all parameters detected during the September 2017 sampling event that exceeded the NC 2L or Groundwater Protection Standards. Ms. Jaclynne Drummond October 31, 2017 Page 5 CDM Smith, on behalf of the County, submitted an Alternate Source Demonstration (ASD) for the site on November 7, 2016. The ASD was prepared in accordance with Solid Waste rule .1633(c)(3), to demonstrate that select metals exceeding the NC 2L or Groundwater Protection Standards detected in monitoring wells at the site are naturally occurring and not related to a release from the landfill. As part of the ASD, in order to determine if turbidity was a contributing factor to total reported metals, filtered samples were collected during the September 2016 sampling event and analyzed for dissolved metals. Based on the sampling results, standard metal exceedances were determined to be indicative of naturally occurring background concentrations as opposed to a release from the landfill. During the September 2017 sampling event, filtered metals samples were collected from monitoring wells MW-12, -16, -20, -25, -25D, and -26 due to an elevated turbidity (i.e. greater than 10 Nephelometric Turbidity Units). Total metals that exceeded the NC 2L or Groundwater Protection Standards from these wells were analyzed for dissolved metals. Below is a summary of the dissolved metals exceedances. All exceedances had “J” flag detections. Cobalt: MW-16, -25, and -26 Vanadium: MW-12, -16, -20, -25, -25D, and -26 Dissolved metal sample results are provided in Table 4. Based on qualitative and quantitative evaluation of current and historic groundwater sampling data, the NC 2L or Groundwater Protection Standard metal exceedances from the September 2017 sampling event were determined to be indicative of naturally occurring background concentrations as opposed to a release from the landfill. The County will continue with the semi-annual groundwater monitoring program. The next sampling event will take place during the spring of 2018.
