RE: Health Risk Evaluation Incident # 15063 Randy Simmerson Well Sampling Results
1717 Hamptonville Road
Yadkinville, NC During this sampling event, four 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)
92531085009 Bromodichloromethane 1.0 80*
Chloroform 5.4 80*
Dibromochloromethane 0.42 80*
Toluene 2.5 1,000
µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion.
* As total trihalomethanes. 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.
