Wendell, NC 27591 To Whom It May Concern: Subject: Water Supply Well Sample Results for 1524 Eagle Rock Rd. (WSW-3) (TF-17375/Country Crossroads Grocery Incident/Wendell/Wake Co.) On July 20, 2023, our Trust Fund contractor sampled a water supply well located on the subject property. The sample was collected as part of the ongoing investigation of a petroleum release at Country Crossroads Grocery. The laboratory results and associated health risk evaluation are enclosed. According to our toxicologist, there are no restrictions on the use of the water at this time. If you have questions regarding the evaluation, please contact Dave Lilley, Environmental Toxicologist at 919-707-8241 or david.lilley@deq.nc.gov . If you have any questions regarding the incident assessment/investigation, please contact the incident manager, Mark Petermann, at 919-522-7955 or mark.petermann@deq.nc.gov . Sincerely, Linda L. Blalock for Mark Petermann Environmental Engineer Federal Trust Fund Enclosures per HRE WSW 4 cc: Mark Petermann August 2, 2023 TO: Linda Blalock NC UST Section RE: Health Risk Evaluation Incident # 17375 Pearce and Clark Properties, LLC Well Sampling Results 1532 Eagle Rock Rd. Wendell, NC During this sampling event, one contaminant was 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 the contaminant concentration exceeds the applicable standard for using the water for drinking and cooking, the contaminant concentration is 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 concentration with the applicable standard: Sample ID Contaminant Concentration (µg/L) MCL (µg/L) 2L (µg/L) 23G3086-13 Chloroform 0.25 80* µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion. * As total trihalomethanes. RECOMMENDATION: The detected contaminant did not exceed the applicable water standard. Therefore, no restrictions on the use of this water are recommended at this time.
