Dear Mr. and Mrs. Feehan:

August 27, 2019
Re: Water Supply Sample Analytical Results
Incident Number: 20117
Site Name: Carolina Fast Mart #2
Concord, Cabarrus County
Please find attached the Sample Analytical Results for a water sample collected from your well, identified
as WSW-1 A, located at 2143 Cold Springs Road, Concord, Cabarrus County on May 7, 2019. The
sample was collected and analyzed as part of the investigation of a petroleum release in the vicinity
(Carolina Fast Mart #2, Incident Number 20117). 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.
If you have any questions, please contact Dave Lilley at [phone] or contact me by email at
Trudy.Beverlygncdenr.gov or by telephone at [phone].
Sincerely,
%-�`? �

RE: Health Risk Evaluation
Tracking ID: 20117
William Feehan Well Sampling Results
2143 Cold Springs Road
Concord, 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)
9050157-03 Chloroform 0.33 80*
Naphthalene 0.67 6 * *
µg/L — Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion.
* * As total trihalomethanes.
** This value is based on odor, the health -based value is 100 µg/L.
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.
