Re: Water Supply Sample Analytical Results
Incident Numbers: 14414 & 91340
Site Name: Colonial Pipeline - Kannapolis
Booster Station & Colonial Pipeline -
Kannapolis Booster Station #2
Concord, Cabarrus County
An influent (pre filter) samples were collected from the wells identified as DW-Cook-
Influent_08/22/19 and DW-Coren-Influent_08/22/19, located at 9221 and 9261 Mooresville
Road, Concord, Cabarrus County on August 22, 2019, as part of the investigation of a petroleum
release in the vicinity (Colonial Pipeline - Kannapolis Booster Station, Incident Number 14414
and Colonial Pipeline - Kannapolis Booster Station #2, Incident Number 91340). The water
sample was analyzed for specific target analytes (contaminants), which are listed on the attached
Sample Analytical Results. No contaminants were detected in the water for the DW-Cook-
Influent_08/22/19 sample. Contaminants were detected in the DW-Coren-Influent_08/22/19
water sample, as shown on the attached Sample Analytical Results.
Because contaminants were detected in the DW-Coren-Influent_08/22/19 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.Beverly(a)ncdenr.gov or by telephone at [phone].

RE: Health Risk Evaluation
Tracking Number: 14414 & 91340
Coren Well Sampling Results (Inf)
9221 Mooresville 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)

L (µg/L)
9080340-03
Total Xylenes
2.01
10,000
Toluene
1.6
1,000
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.
