This letter report presents the results of the recently completed sampling at the C&D Landfill and constitutes the second semi-annual sampling event for 2020. The approved monitoring well network for the C&D Landfill consists of background wells CD -Is and -1d; compliance wells CD-2, -4 Rep, -7, and -9; and surface water sample location SW-3. CD-4 Rep was installed in January 2009 as part of the proposed Phase 1 C&D Landfill expansion. Monitoring well CD-7, formerly piezometer B-7, was added to the monitoring program in July 2014 as part of the Phase 2 C&D Landfill expansion. Monitoring well CD-9 was installed on March 19, 2017, as part of the Phase 3 C&D Landfill expansion. Field activities and sampling results for the groundwater and surface water samples are discussed below. Field Activities Groundwater and surface water samples from the Cabarrus County C&D Landfill were collected on September 22, 23, and 25, 2020. Groundwater samples were collected from the monitoring wells by use of disposable, laboratory decontaminated bailers. Monitoring well locations and the surface water location for the C&D Landfill are provided on Figure 1. Groundwater elevations were measured at each well prior to sampling and are presented in Table 1. Well construction details for each monitoring well are also provided in Table 1. These groundwater elevations were used to construct potentiometric contours for this sampling event and are presented on Figure 1. After depth to groundwater was measured, each well was purged prior to sampling to provide fresh formation water within the well water column. Each purge volume was measured for pH, Of WATER + ENVIRONMENT +TRANSPORTATION + ENERGY + FACILITIES Smith Ms. Jaclynne Drummond December 29, 2020 Page 2 conductivity, turbidity, temperature, dissolved oxygen, and oxidation-reduction potential using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter. The water quality parameters at the time of sampling are presented in Table 2. Sampling Results Pace Analytical Services, LLC, located in West Columbia, South Carolina, analyzed the groundwater and surface water samples for North Carolina Appendix I volatile organic compounds (VOCs) plus tetrahydrofuran, North Carolina Appendix I metals plus iron, mercury, and manganese, alkalinity, total dissolved solids (TDS), chloride, and sulfate with the exception of CD-4 Rep. Samples collected from CD-4 Rep were analyzed for North Carolina Appendix I VOCs and metals. In a letter dated May 28, 2019, the Solid Waste Section requested that all groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On July 1, 2019, the Solid Waste Section approved the removal of 1,4-dioxane from the sampling program due to two consecutive non -detect events (January and May 2019), except for SW-3. 1,4-Dioxane sample results for SW-3 are provided below. The analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below the method reporting limit (MRL). All monitoring wells for the C&D Landfill had detections of analytes above the MDL but below the MRL. These detections were qualified as estimated or "J" flags. The following list indicates the analytes detected above the MRL at each sampling location. No "J" flag detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Standard, Interim Maximum Allowable Concentration (IMAC) Standard, or 15A NCAC 02B .0211 (NC 2B) or North Carolina In -Stream Target Value Surface Water Quality Standards for Class C Waters.

These constituents along with their location are listed below. Cobalt: CD-2, -4 Rep, and -9 Lead: SW-3 Thallium: CD-7 Vanadium: CD-1s Equipment and trip blanks were analyzed for quality control. A duplicate sample was also analyzed for quality control. Methylene chloride was detected in the trip blank as an estimated concentration below its NC 2L Groundwater Standard. Acetone was detected as an estimated concentration in the equipment blank below its NC 2L Groundwater Standard. The duplicate sample, identified as CD DUP, was collected from CD-9. The duplicate sample had similar concentrations as those detected in CD-9, except for an estimated detection of beryllium below its IMAC and a detection of lead below its NC 2L Groundwater Standard. Metals detected above the standards are likely naturally occurring based on concentrations in the background monitoring wells or are from elevated turbidity at the time of sample collection. Benzene, tetra chloroethene, and vinyl chloride have recently been detected above the NC 2L Groundwater 0 Smith Ms. Jaclynne Drummond December 29, 2020 Page 4 Standards in samples collected from CD-7. In September 2020, only vinyl chloride was detected above the NC 2L Standards. A complete summary of all detected constituents from the September 2020 sampling event is presented in Table 3. The laboratory analytical reports are provided in Appendix A. The next semi-annual sampling event will be completed in the spring of 2021.
