Drinking Water Regulations
|
|
Summary: The North Carolina Department of Health and Human Services (“NC DHHS”) has set a health goal for GenX in drinking water at 140 parts per trillion (“ppt”). According to NC DHHS, the health screening goal is protective for all individuals, including the most vulnerable populations. Drinking water well sampling for GenX compounds began in 2012 on a limited basis near the Cape Fear River, and has significantly expanded to include testing in nearby areas.

Summary:
- There is an Interim Maximum Allowable Concentration of 2,000 ppt for PFOA.
- The North Carolina Division of Water Resources (“DWR”) has proposed a rule that, if promulgated, would establish the maximum concentration of PFOA and PFOS (combined) in groundwater at 70 ppt.
