The sample was collected and analyzed 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. 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 (919) 707-8241 or contact me by email at Trudy. BeverlyOncdenr.gov or by telephone at (704) 235-2182. Sincerely, . a Trudy Beverly, P.G.

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 the contaminant concentration exceeds the applicable standard for using the water for drinking and cooking, the contaminant concentration is 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 concentration with the applicable standard: Sample ID Contaminant Concentration (µg/1)* MCL (µg/1) 2L (µg/1) 8080423-07 Methyl-tert-Butyl Ether 1.3 20 * The abbreviation µg/1 stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion. RECOMMENDATION: The detected contaminant did not exceed the applicable water standard. Therefore, no restrictions on the use of this water are recommended at this time. za�*fio� David Lilley, Environmental Toxicologist Division of Waste Management, NCDEQ 0Rl �TH� Pepahrmnl of &Mmnmentnl-\.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 �Full-Service Analytical P R I S M Environmental Solutions LABORATORIES INC.

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 the contaminant concentration exceeds the applicable standard for using the water for drinking and cooking, the contaminant concentration is 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 concentration with the applicable standard: Sample ID Contaminant Concentration (µg/1)* MCL (µg/1) 2L (µg/1) 8080423-07 Methyl-tert-Butyl Ether 1.3 20 * The abbreviation µg/1 stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion. RECOMMENDATION: The detected contaminant did not exceed the applicable water standard. Therefore, no restrictions on the use of this water are recommended at this time. za�*fio� David Lilley, Environmental Toxicologist Division of Waste Management, NCDEQ 0Rl �TH� Pepahrmnl of &Mmnmentnl-\.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 ROY COOPER Governor MICHAEL S.
