RE: Health Risk Evaluation
Incident # 26305
Cherie McBeth-Davis Well Sampling Results (Outlet from POE)
8105 NC Hwy 39
Henderson, NC

During this sampling event, one contaminant was 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 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/L)

MCL (µg/L)

2L (µg/L)
0020001-14 1,2-Dibromoethane 0.041 0.05
µg/L – 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.
