Sanford, NC 27332 Re: Health Risk Evaluation of Water Supply Tracking ID: 42035 Dear Ms. Thomas: Please find attached the Sample Analytical Results for a water sample collected from your well, identified as WSW-2, located at 0 HWY NC 87 (parcel ID 37105_966053210300), Sanford, Lee County, on December 20, 2022. The sample was collected and analyzed as part of the investigation of a petroleum release in the vicinity. The water sample was analyzed for specific target analytes (contaminants), which are listed on the attached Sample Analytical Results. Contaminants were detected in the water sample, as shown on the attached Sample Analytical Results. Because contaminants were detected in the water sample, a Health Risk Evaluation of the water supply was performed by an environmental toxicologist in the Division of Waste Management. The Health Risk Evaluation, which is attached also, compares the detected concentration of contaminants to acceptable concentrations and provides a recommendation for safe use of the water. We were unable to contact the well user. Therefore, as the property owner we request that you forward a copy of this report to any well users at the sampled location. If you have any questions, please contact Dave Lilley at (919) 707-8241 or contact me at the address or telephone number listed below for the Fayetteville Regional Office. Sincerely, Michael H. Haseltine, L.G.

Thomas water supply well, identified as WSW-2, located at 5680 NC Highway 87 South, Sanford, Lee County. Please perform a health risk evaluation and send the evaluation with your recommendation and a copy of this memo to me. I will then forward the health risk evaluation and recommendation to any well users. If you have questions or need additional information, please contact me at the address or telephone number below. Thank you for your assistance. Attachment(s): WSW-2 Sample Analytical Results January 18, 2023 TO: Michael Haseltine Fayetteville Regional Office NC UST Section RE: Health Risk Evaluation Incident # 42035 Eugene L. Thomas Well Sampling Results 5680 NC Highway 87 South Sanford, NC During this sampling event, two contaminants were detected in the well water. The standards used to determine if the water is suitable for drinking and cooking are the United States Environmental Protection Agency’s Maximum Contaminant Levels (MCLs) or, if no MCLs exist, North Carolina Groundwater Standards (2L). If any contaminant concentrations exceed applicable standards for using the water for drinking and cooking, those contaminant concentrations are further analyzed to determine if the water is suitable for other household uses, such as showering, bathing, washing dishes, flushing toilets, and hand washing. The chart below compares the detected contaminant concentrations with the applicable standards: Sample ID Contaminant Concentration (µg/L) MCL (µg/L) 2L (µg/L) FC1527-11 Di-Isopropyl Ether 0.20 70 Methyl Tert Butyl Ether 5.3 20 µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion. RECOMMENDATION: None of the contaminants detected exceeded the applicable water standards. Therefore, no restrictions on the use of this water are recommended at this time.
