This letter report details water supply well sampling requested by the NCDWM-UST. The site’s location, vicinity, and layout are shown on the enclosed Figures 1, 2, and 3. Terraquest personnel sampled water supply wells WSW1, WSW2, WSW4, and WSW5 on October 25, 2023. Prior to sampling the water supply wells, a spigot located as close to the wellhead as possible was allowed to flow for 10-15 minutes to purge the bladder tank and allow for the collection of a sample representative of the aquifer. Terraquest personnel wearing new, disposable nitrile gloves, collected samples directly from the well spigot into laboratory-prepared containers. Samples were labeled, packed on ice, and shipped to an NC-certified laboratory for analysis per 6200B. No petroleum-type compounds were reported for any of the samples as shown in the attached Table 1 and the laboratory report. Please contact me with any questions or concerns you may have. Thank you. Sincerely, TERRAQUEST ENVIRONMENTAL CONSULTANTS, P.C. Ryan D. Kerins Project Manager Enclosures ONSULTANTS, P.C.CENVIRONMENTAL ENVIRONMENTAL CONSULTANTS, P.C.

Unless otherwise noted below, the samples arrived in good condition, and, where required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.0°C GC/MS VOA Method SM6200_B: The following analyte recovered outside control limits for the Laboratory Control Sample (LCS) associated with analytical batch 400-648802: Dichlorodifluoromethane. This is not indicative of a systematic control problem because this was a random marginal exceedance. Qualified results have been reported. No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
