(CDM Smith), on behalf of Wake County (County), is submitting an electronic copy of the May 2021 semi-annual sampling event report for the East Wake Landfill - Rigsbee Property (Site). This letter report presents the results of the most recent semi-annual sampling event and constitutes the first semi-annual sampling event for 2021. The approved groundwater monitoring network consists of one background well (i.e., MW-01), and five downgradient monitoring wells (i.e., MW-02, -03, -04S, -04D, and -07). Field activities and sampling results are discussed below. Background The Site is located on two parcels. One of the parcels as shown on Figure 1 is owned by Carolyn Properties, LLC and contains approximately 27 acres of waste. This parcel is referred to as the J.T. Knott property and is currently part of the North Carolina Department of Environmental Quality's Inactive Hazardous Sites Pre -Regulatory Landfill program. The background monitoring well for the portion of the landfill located on the James Ervin Rigsbee (Rigsbee) property, MW-01, is located on this parcel along with a private airport and several businesses. The parcel owned by Mr. Rigsbee contains approximately 46 acres of waste located in two separate areas as shown on Figure 1. This parcel borders the J.T. Knott property to the south and west. A large portion of the parcel is used for cattle pasture and includes an explosive storage company and associated storage and office trailers, a home with a detached garage and two barns, and a storage area for abandoned automobiles. All monitoring wells for the Site, except for the background well, are located on this parcel. This portion of the Site operated under Permit Number 92-02 until the two waste disposal areas ceased operations in 1983 (Area C) and 1985 (Area D). The two areas of waste located on the Rigsbee property are known as Areas C and D as shown on Figure 1. Groundwater assessment for Area C is being conducted under the supervision of the Inactive tD WATER + ENVIRONMENT +TRANSPORTATION + ENERGY + FACILITIES Smith Ms. Jaclynne Drummond June 24, 2021 Page 2 Hazardous Sites Pre -Regulatory Landfill Unit after this area of waste was determined to be eligible for the program in the fall of 2012. Since 2012, the County has voluntarily collected groundwater samples semi-annually from the Area C monitoring wells (i.e., MW-5, -6, -8, -9, and -10). On September 13, 2018, the Solid Waste Section (SWS) approved the discontinuation of the groundwater monitoring of Area C, beginning with the fall 2018 sampling event. Field Activities Groundwater samples were collected on May 14, 2021, by use of disposable, laboratory decontaminated bailers. Monitoring well sampling locations are presented on Figure 1. Well construction details are provided in Table 1. Groundwater elevations were measured at each well on May 13, 2021, 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 for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-reduction potential using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter. Wells with elevated turbidity were allowed to stabilize prior to sample collection. The water quality parameters at the time of sampling are presented in Table 2. Alternate Source Demonstration On August 17, 2020, CDM Smith submitted an Alternate Source Demonstration (ASD) for the Site on behalf of the County. The purpose of the ASD was to demonstrate that metals exceeding the 15A NCAC 02L .0202 (NC 2L) Groundwater Standards or Interim Maximum Allowable Concentrations (IMAC) are naturally occurring and not related to a release from the landfill. The ASD was prepared using analytical data from the background monitoring well, MW-01, that was collected on a quarterly basis from January 2018 to February 2020 to develop upper tolerance limits (UTLs) for specific analytes that historically exceeded their respective NC 2L Groundwater Standard or IMAC. Based on statistical analysis, a UTL of 2.82 parts per billion (ppb) was proposed for cobalt and a UTL of 2 ppb was proposed for vanadium. The SWS approved these proposed UTLs on August 20, 2020. 0 Smith Ms. Jaclynne Drummond June 24, 2021 Page 3 Sampling Results Pace Analytical Services, LLC, located in West Columbia, South Carolina, analyzed the groundwater samples for the North Carolina Appendix I volatile organic compounds and Appendix I metals. In a letter dated May 29, 2018, the SWS stated that all groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On June 26, 2019, the SWS approved the removal of 1,4-dioxane from the sampling program for all monitoring wells, with the exceptions of MW-03, -045, and -4D, due to two consecutive non -detect events (October 2018 and April 2019). Samples were collected from the wells requiring the 1,4-dioxane analysis during the May 2021 semi- annual sampling event. Sample results are provided below. The analytical results were reported to the laboratory specific method detection limit (MDL) and are quantifiable at or below the laboratory limit of quantitation (LOQ). All monitoring wells for the Site had detections of analytes above the MDL but below the LOQ that were qualified as estimated or "J" flags. The following list indicates the analytes detected above the LOQ at each sampling location. No "J" flag detections are provided. Underlined analytes exceeded the NC 2L Groundwater Standard, IMAC, or UTL. A complete summary of all detected and estimated concentrations for the May 2021 sampling event and previous sampling events is provided in Table 4. The laboratory analytical data report is provided in Appendix A.

The "J" flag constituents above the standards along with their locations are listed below. Cobalt: MW-02 Thallium: MW-01 and -02 Vanadium: MW-03, -04S, and -07 An equipment blank, trip blank, and duplicate sample were analyzed for quality control. Acetone was detected as an estimated concentration in the equipment blank below its NC 2L Standard. No analytes were detected in the equipment or trip blanks above the MDL. The duplicate sample, identified as DUP, was collected from MW-07 and had similar analyte concentrations as those detected in MW-07. Table 5 presents a summary of all parameters detected during the May 2021 sampling event that exceeded the NC 2L Groundwater Standards, IMACs, or UTLs. Additional metals samples were collected from all monitoring wells during the May 2021 sampling event for the laboratory to filter and analyze due to elevated turbidity (i.e., greater than 10 Nephelometric Turbidity Units). Total metals that exceeded the NC 2L Groundwater Standards, IMACs, or UTLs were analyzed for dissolved metals to determine if turbidity was a contributing factor to total reported metals. Cobalt was detected in the dissolved metal samples collected from MW-04S, -04D, and -07 above its UTL. Barium was also detected above its NC 2L Groundwater Standard in the dissolved metal sample collected from MW-04D. This detection of barium had a "D" flag, indicating that the sample was analyzed at a dilution greater than one. Additionally, cadmium was detected above its NC 2L Groundwater Standard in the dissolved metal sample collected from MW-07. There were no other dissolved metal exceedances. Dissolved metal sample results are provided in Table 4 and the laboratory report is provided in Appendix A. The County will continue with the semi-annual groundwater monitoring program for Area D. The concentration of 1,4-dioxane will continue to be monitored in MW-03, -045, and -04D. The next sampling event will be completed in the fall of 2021. 0 Smith Ms. Jaclynne Drummond June 24, 2021 Page 5 If you have any questions or require further explanation, do not hesitate to call me at (919) 325-3500.
