(Terracon) is pleased to submit this monitoring well and water supply well abandonment letter report for the above referenced property. This report has been prepared in general accordance with North Carolina Department of Environmental Quality (NCDEQ), Underground Storage Tank (UST) Section Assessment Guidelines for UST Releases and Corrective Action Guidelines for UST Releases,dated January 19, 2021, and Task Authorization No. 10 approved on December 16, 2022. The Wilsonville General Store site, located at 10580 U.S. Highway 64 East in Wilsonville, North Carolina (site) (Figure 1), is comprised of 2.26 acres and contains a single-story commercial building operated as Wilsonville General Store (gas station and convenience store). The remainder of the site consists of paved, landscaped, and grassy areas. The site has been developed as a gasoline retail facility since the late-1930s. A release was discovered in August 1987 from a former on-site underground storage tank (UST) system. At the direction of NCDEQ, Terracon oversaw the abandonment of the on-site water supply well WSW-1 and on-site monitoring wells MW-5r, MW-6r, MW-8r, MW-15, and MW-16. The wells were abandoned on January 30, 2023, by a North Carolina-licensed well driller (SR&R Environmental, Inc.) using neat cement and concrete grout. An updated site diagram and water supply well location map is provided in Figure 1 and Figure 2 respectively. A copy of the well abandonment records and photographs are provided in Appendix A.
