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 February 22, 2023. 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 water samples, as shown on the attached Sample Analytical Results. No petroleum contaminants were detected in the post-treatment water sample, therefore the POE is effectively removing petroleum contaminants from the water supply well. Acetone was detected in the post-treatment water
sample. Acetone is a common lab contaminant that 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. 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,

Incident # 30671 Circle K Well Sampling Results (Pre) 1031 NC Highway 87 N Burlington, 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)
LA88246-1 Dichlorodifluoromethane 0.37 1,000
Methyl Tert Butyl Ether 2.0 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.

Re: Health Risk Evaluation of Water Supply Tracking ID: Former Pantry #161-B (Circle K Store #2720161), Incident #30671 Dear Ms. Basham: Please find attached the Sample Analytical Results for water samples collected from your well, identified as WW11, located at 1050 NC Highway 87 North, Elon, Alamance County, on February 22, 2023. 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 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
petroleum contaminants from the water supply well. 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. 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,

NC UST Section RE: Health Risk Evaluation Incident # 30671 Basham Well Sampling Results (Pre)
1050 NC Highway 87 N Elon, 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)
LA88246-16 Methyl Tert Butyl Ether 0.13 20
µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion. 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.

Incident # 30671 Basham Well Sampling Results (Mid) 1050 NC Highway 87 N Elon, 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)
LA88246-17 Acetone 3.4 6,000
µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion.
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.

Contaminants were detected in the water sample, as shown on the attached
Sample Analytical Results. Tetrachloroethylene and 1,1-Dichloroethylene are chlorinated solvents and are 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.

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)
