Re: Health Risk Evaluation of Water Supply
Tracking ID: Incident #12913,
WSW-2765, McMillan Well

Dear Mr. Neel:

Please find attached the Sample Analytical Results for water samples collected from your well, identified
as WSW-2765, located at 2765 Union Ridge Road, Burlington, Alamance County, on February 28, 2017.
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 samples, 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 water supply well at this
property is treated by a Point-of-Entry treatment system to remove contaminants. Water samples were taken
at three points on the system. A Health Risk Evaluation was performed for any of the samples that contained
contaminants above the detection limits. The post-treatment sample contained an amount of chloromethane
that did not exceed the applicable water standard.

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,
Mindy Lepard
Hydrogeologist
