Re: Water Supply Sample Analytical Results
Incident Number: 13401
Site Name: 85 Kwik Mart
Concord, Cabarrus County
Please find attached the Sample Analytical Results for a water sample collected from your well, identified
as WSW -Ring Power Crane, located 5014 Davidson Highway, Concord, Cabarrus County, on February 18, 2019.
The sample was collected and analyzed as part of the investigation of a petroleum release in the vicinity (85 Kwik
Mart, Incident Number 13401). 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
[e-mail] or by telephone at [phone].
Sincerely,
3ua&

RE: Health Risk Evaluation
Tracking ID: 13401
Ring Power Corporation Well Sampling Results
5014 Davidson Highway
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)
92418242006
1,2-Dichloroethane
0.60
5
Methyl-tert-butyl ether
2.9
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.
