This letter report presents the results of the most recent semi-annual sampling event and constitutes the first semi- annual sampling event for 2017. The approved groundwater monitoring network consists of one background well (i.e. MW-1), and ten downgradient monitoring wells (i.e. MW-2, -3, -4S, -4D, -5, -6, -7, -8, -9, and -10). Field activities and sampling results are discussed below. Background The East Wake Landfill (landfill) 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-1, 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 landfill, with the exception of the background well, are located on this parcel. This portion of the landfill operated under Permit Number 92-02 until the two waste disposal areas ceased operations in 1983 (Area C) and 1985 (Area D). Ms. Jaclynne Drummond June 27, 2017 Page 2 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 Hazardous Sites Pre-Regulatory Landfill Unit (Unit) after this area of waste was determined to be eligible for the program in the fall of 2012. The County will continue the semi-annual monitoring program for Area C until the Unit finalizes its assessment of groundwater. Field Activities Groundwater samples from the landfill monitoring wells were collected on April 27, 2017. Monitoring well MW-5 was buried underneath a stockpile and was not sampled during the spring 2017 sampling event. All samples were collected 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 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 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 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 well locations 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 (Area C and D monitoring wells). No “J” flag detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater Standard or Groundwater Protection Standard. A complete summary of all detected and estimated concentrations for the April 2017 sampling event is provided in Table 4. The laboratory analytical data report is provided in Appendix A. Ms. Jaclynne Drummond June 27, 2017 Page 3 MW-1 (Background) Metals: Barium, Beryllium, Copper, Zinc Volatile Organic Compounds: None Detected AREA C MW-5 Metals: Not Sampled Volatile Organic Compounds: Not Sampled MW-6 Metals: Barium, Copper, Zinc Volatile Organic Compounds: Benzene, Chlorobenzene, 1,4-Dichlorobenzene MW-8 Metals: Barium Volatile Organic Compounds: Benzene, Chlorobenzene, 1,4-Dichlorobenzene MW-9 Metals: Barium, Cobalt Volatile Organic Compounds: Benzene, Chlorobenzene, 1,4-Dichlorobenzene MW-10 Metals: Barium Volatile Organic Compounds: Benzene, Chlorobenzene, 1,4-Dichlorobenzene AREA D MW-2 Metals: Barium, Beryllium, Copper, Lead, Vanadium, Zinc Volatile Organic Compounds: None Detected MW-3 Metals: Barium Volatile Organic Compounds: Chlorobenzene MW-4S Metals: Barium Volatile Organic Compounds: None Detected MW-4D Metals: Barium, Cobalt, Copper, Zinc Volatile Organic Compounds: Chlorobenzene, 1,4-Dichlorobenzene Ms. Jaclynne Drummond June 27, 2017 Page 4 MW-7 Metals: Beryllium, Zinc Volatile Organic Compounds: None Detected “J” flags were not included in the previous list, but several locations had “J” flag detections that exceeded the standards. The “J” flag constituents above the standards along with their locations are listed below. Cobalt: MW-1, -2, -4S, -6, -7, and -10 Thallium: MW-1, -2, and -9 Vanadium: MW-1, -3, -4S, -4D, -6, -7, -8, and -10 Vinyl Chloride: MW-9 Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for quality control. Acetone, 2-butanone, and copper were detected as estimated concentrations in the equipment blank below their respective NC 2L Standards. No analytes were detected in the trip blank above the MDL. The duplicate sample, identified as MW-10 dup, was collected from MW-10 and had similar analyte concentrations as those detected in MW-10. Table 5 presents a summary of all parameters detected during the April 2017 sampling event that exceeded the NC 2L or Groundwater Protection Standards. Metals exceeding the standards are likely a result from elevated turbidity at the time of sample collection. Future analytical results above the standards will be monitored to determine if a trend appears. The County will continue with the semi-annual groundwater monitoring program. The next sampling event will take place during the Fall of 2017. If you have any questions or require further explanation, do not hesitate to call me at (919) 325-3500. Very truly yours, Mathew F.

The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved NELAC standards, the Shealy Environmental Services, Inc. ("Shealy") Quality Assurance Management Plan (QAMP), standard operating procedures (SOPs), and Shealy policies. Any exceptions to the NELAC standards, the QAMP, SOPs or policies are qualified on the results page or discussed below.

VOC 8260B The associated continuing calibration verification (CCV) recovered above the upper control limit for DCDFM, Acetone and Acrylonitrile. The associated samples for this CCV were non-detect for these three analytes; therefore, the data has been reported except sample SD28010-003 (MW-3) for Acetone and SD28020-006 (MW-6) for DCDFM. Both of these samples were rerun for affected targets. The CCV associated with the re-analysis passed criteria.
