P.O. Box 52085 Phoenix, Arizona 85072-5085 Re: Health Risk Evaluation of Water Supply Tracking ID: Former Pantry #161-B (Circle K Store #2720161), Incident #30671 Dear Sirs: Please find attached the Sample Analytical Results for water samples collected from your well, identified as WW1, located at 1031 NC Highway 87 North, Elon, Alamance County, on November 29, 2022. The water supply well at this property is treated by a Point-of-Entry treatment system (POE) to remove
contaminants. Water samples were taken at three points on the system. 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 pre-treatment water sample, as shown on the attached Sample Analytical Results. No contaminants were detected in the post-treatment water sample, therefore the POE is effectively removing contaminants from the water supply well.
Because contaminants were detected in the pre-treatment 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. If you have any questions, please contact Dave Lilley at [phone] or contact me at the address or telephone number listed below for the Winston-Salem Regional Office. Sincerely,

Elon, North Carolina 27244 Re: Health Risk Evaluation of Water Supply Tracking ID: Former Pantry #161-B (Circle K Store #2720161), Incident #30671 Dear Ms. and Mrs. Whitaker: Please find attached the Sample Analytical Results for a water sample collected from your well, identified as WW23, located at 1075 NC Highway 87 North, Elon, Alamance County, on November 29, 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. Tetrachloroethene is a chlorinated solvent and is not related to petroleum contamination.
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.

Dear Ms. Routh: Please find attached the Sample Analytical Results for a water sample collected from your well, identified as WW30, located at 2049 Routh Road, Burlington, Alamance County, on November 29, 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. Hexachlorobutadiene was detected above the regulatory standard in the November 2022 sample. The footnotes and quality control data in the lab results indicate that detection may have been in error. The water supply well was resampled on February 23, 2023. Hexachlorobutadiene was not detected in that sample.
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. The Health Risk Evaluation was performed on the November 2022 sample. A Health Risk Evaluation on the February 2023 sample, in which hexachlorobutadiene was not detected, will be performed soon.
If you have any questions, please contact Dave Lilley at [phone] or contact me at the address or telephone
