NC UST Section RE: Health Risk Evaluation Incident # 42202
PRO Car Wash & Detail Well Sampling Results
648 N. Reilly Road Fayetteville, 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)
L1449006-03 Methyl tert-butyl ether 0.627 20
Naphthalene 2.12 6
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.
