Re: Health Risk Evaluation of Water Supply Tracking ID: Inc. No. 47085 Dear Mr, & Mrs. Wooten: Please find attached the Sample Analytical Results for the water samples collected from your well, identified as WSW-1, located at 112 Stagecoach Road, Gastonia, Gaston County, on December 19, 2023. The samples were collected and analyzed as part of the investigation of a petroleum release in the vicinity. The water samples were analyzed for specific target analytes (contaminants), which are listed on the attached Sample Analytical Results. Contaminants were detected in the water samples, as shown on
the attached Sample Analytical Results. Because contaminants were detected in the water sample, a Health Risk Evaluation of each water
supply sample 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.
If you have any questions, please contact David Lilley at [phone], or contact me at [phone]. Sincerely, Brad C. Newton, P.G. Hydrogeologist

RE: Health Risk Evaluation Incident # 47085 Wooten Well Sampling Results 112 Stagecoach Road Gastonia, NC
During this sampling event, three 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)
µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion. * As total trihalomethanes.

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.
