REGAN Secretary MICHAEL SCM Director Coren Everett, Jr. 9221 Mooresville Road Concord, NC 28207 Dear Mr. Everett: NORTH CAROLINA Environmental Quality October 23, 2019 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.

REGAN Secretary MICHAEL SCOTT Director TO: Trudy Beverly Mooresville Regional Office NC UST Section NORTH CAROLINA Environmental Quality October 23, 2019 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) MCL (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. �Y David Lilley, Environmental Toxicologist Division of Waste Management, NCDEQ gHTh Pepartnwd oEMmnl-\.eo*/ North Carolina Department of Environmental Quality I Division of Waste Management 217 West Jones Street 1 1646 Mail Service Center I Raleigh, North Carolina 27699-1646 919.707.8200 Beverly, Trudy From: Sent: To: Beverly, Trudy Wednesday, October 23, 2019 1:02 PM 'David Troutman'; 'Mike Downs' Subject: 9261 Mooresville Road, Concord - Water Supply Well Sample Results & HRE #14414 Colonial Pipeline - Kannapolis Booster Station & #91340 Colonial Pipeline - Kannapolis Booster Station #2 Attachments: MO-14414_14414_CA_WSW_20191023_Cook & Coren Results Letter.pdf Please see the attached water supply well sample results and Health Risk Evaluation for 9261 Mooresville Road (Coren Influent), Kannapolis/Concord, Cabarrus County, North Carolina.
