Incident # 3327
Kittany, Inc. Well Sampling Results 3121 NC Highway 86 North Hillsborough, NC
During this sampling event, three 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)
98541 Bromodichloromethane 1.34 80*
Chlorodibromomethane 0.615 80*
Chloroform 4.23 80*
µg/L – Micrograms of contaminant per liter of water, roughly equivalent to parts per billion.
* As total trihalomethanes.
RECOMMENDATION: None of the contaminants detected exceed the applicable water standards. Therefore, no restrictions on the use of this water are recommended at this time.

Although none of the contaminant levels exceed the applicable regulatory values, the levels of
bromodichloromethane and chlorodibromomethane in this well exceed the values recommended by the North
Carolina Department of Health and Human Services (DHHS) of the 0.6 µg/L and 0.5 µg/L, respectively. The well user may want to contact the Private Well and Health program at (919) 707- 5900 for more information.
