The scope of work performed by WR included groundwater sample collection from existing groundwater monitoring wells and surface water sample collection along Richland Creek in accordance with the North Carolina Department of Environment Quality (NCDEQ) approved Water Quality and Landfill Gas Monitoring Plan dated September 2008, which will be referenced as “The Plan” throughout this report. The closed NC Fairgrounds Landfill is located approximately four miles west of downtown Raleigh and approximately 1,600 feet northeast of the intersection of NC Highway 54 (Chapel Hill Road) and Nowell Road (Figure 1). The facility was permitted as a sanitary landfill on August 9, 1982 (Permit #92-08). According to documentation reviewed by WR, the closed landfill was operated between approximately 1982 and 1988. Samples from five groundwater monitoring wells and two surface water collection points are intended to be collected and tested on annual basis in accordance with The Plan and correspondence received from the Department of Waste Management. Closed NC Fairgrounds Landfill Annual Groundwater and Surface Water Monitoring Report WR Project No.: 02000082.20 September 2017 Page 2 1.0 WATER QUALITY SAMPLING METHODOLOGY 1.1 Groundwater Sampling Five groundwater monitoring wells, MW-1, MW-2, MW-3, MW-4, and MW-5, were installed at the site in November 2000 at locations proximal to two waste areas. Figure 2 illustrates the locations of the waste boundary and monitoring wells. Monitoring well construction details are summarized in Table 1 and copies of the boring logs and well completion reports for the monitoring wells are included as Appendix A. Groundwater sampling activities were performed on July 14, 2017 in accordance with protocols detailed in The Plan. Prior to monitoring well gauging, each monitoring well was opened to allow water levels to equilibrate to atmospheric pressure. Water levels within each monitoring well were then measured using a decontaminated electronic water level meter. Groundwater elevation measurements were referenced to the top of the well casing. The groundwater elevations were calculated to range from 411.19 to 437.66 feet above mean sea level (MSL) for this sampling event. The July 14, 2017 groundwater elevation data is summarized in Table 1 and a Groundwater Potentiometric Map is included as Figure 2. Each monitoring well was purged using the low-flow technique. During the purging process, turbidity was monitored until a clarity less than 10 Nephelometric Turbidity Units (NTU) was achieved. Final turbidity measurements were recorded in the field notes. Copies of the field notes are included as Appendix B. Following purging activities, groundwater samples were collected using the same polyethylene tubing used to purge the wells. Groundwater samples were decanted into laboratory provided bottleware and immediately placed into an ice-chilled cooler. Collected samples were shipped under proper chain-of- custody to ESC Lab Sciences of Mt. Juliet, TN for analysis of volatile organic compounds (VOCs) by EPA Method 6200B and the eight RCRA metals by EPA Method 6020 and 7470A. 1.2 Surface Water Sampling Surface water samples were also collected on July 14, 2017 from monitoring points designated as SA-1 and SA-2, located along Richland Creek. SA-1 is considered the upstream sampling location (approximately 35° 47’ 28” North and 78° 43’ 43” West) and SA-2 is considered the downstream sampling location (approximately 35° 47’ 31” North and 78° 43’ 37” West). To preserve the integrity of the preservatives within the sample containers, a properly decontaminated Teflon™ ladle was used to collect the surface water samples. The contents of the ladle were immediately decanted into laboratory provided bottleware. The samples were then placed into ice-chilled coolers and shipped under proper chain-of-custody to ESC Lab Sciences of Mt. Juliet, TN for analysis of volatile organic compounds (VOCs) by EPA Method 6200B and the eight RCRA metals by EPA Method 6020 and 7470A. Closed NC Fairgrounds Landfill Annual Groundwater and Surface Water Monitoring Report WR Project No.: 02000082.20 September 2017 Page 3 2.0 LABORATORY ANALYTICAL RESULTS July 2017 - Groundwater and Surface Water Sampling Event The following analytical results exceeded the North Carolina Solid Waste Section Limits (SWSL). •MW-1: Barium – 187 µg/L Cadmium – 1.06 µg/L (J-flag) •MW-3: Barium – 177 µg/L Cadmium – 1.04 µg/L (J-flag) Selenium – 11.2 µg/L No analytes were detected at concentrations that exceeded the North Carolina 2L Standard. No detections were reported in the laboratory’s method blank. Laboratory results for the analytes identified in the July 2017 samples are summarized in Table 2. Copies of the laboratory analytical reports are included as Appendix C. Closed NC Fairgrounds Landfill Annual Groundwater and Surface Water Monitoring Report WR Project No.: 02000082.20 September 2017 Page 4 3.0 SUMMARY OF REGULATORY EXCEEDANCES AND CONCLUSIONS Groundwater and Surface Water Monitoring: •No targeted VOC compounds were detected at concentrations that exceeded their NC SWSL or NC 2L Standard. •MW-1 had detections of Barium and Cadmium (J-flagged) above NC SWSL Standards. •MW-3 had detections of Barium, Cadmium (J-flagged), and Selenium above NC SWSL Standards. •No NC 2L Standard exceedances were present for targeted compounds in any sample location. The next annual groundwater and surface water monitoring event for the Closed NC Fairgrounds Landfill is planned to occur in July 2018.

One phone call, one point of contact, one laboratory. No other lab is as accessible or prepared to handle your needs throughout the country. Our capacity and capability from our single location laboratory is comparable to the collective totals of the network laboratories in our industry. The most significant benefit to our “one location” design is the design of our laboratory campus. The model is conducive to accelerated productivity, decreasing turn-around time, and preventing cross contamination, thus protecting sample integrity. Our focus on premium quality and prompt service allows us to be YOUR LAB OF CHOICE. ESC Lab Sciences has sixty-four client support centers that provide sample pickup and/or the delivery of sampling supplies. If you would like assistance from one of our support offices, please contact our main office. ESC Lab Sciences performs all testing at our central laboratory. 1. Drinking Water 2.
