Kentucky environmental attorney Sanders says EPA is lowing allowable level of PFOA in drinking water wells polluted by Dupont in Parkersburg, WV.

U.S. EPA has issued a consent order to E.I. du Pont de Nemours and Co. that sets a new action level for PFOA – also known as perfluorooctanoic acid, or C-8 – in drinking water for communities surrounding the company’s plant in Parkersburg, W. Va. The order was prompted by a recent EPA Provisional Health Advisory for PFOA.

EPA expects that this change will impact a limited number of residents. Based on current data available to EPA, approximately 14 private residences may need a treatment system or connection to a public water system. Under the new order, DuPont will offer connection to a public water system, treatment, or temporary bottled water to people on public or private water systems if the level of PFOA detected in drinking water is equal to or greater than 0.40 parts per billion.


This action level replaces the 0.50 ppb threshold established under a November 2006 EPA consent order with DuPont. Also, DuPont will take additional samples of private drinking water wells that were installed after 2006 and sample in some previously untested areas. Residents who have questions about this order or PFOA can call EPA’s hotline at 866-575-8543.

PFOA is a synthetic chemical that is not currently regulated under federal environmental laws. It is has been used to make fluoropolymers – substances with special properties used in many industrial applications, including the manufacture of consumer products such as non-stick cookware and all-weather clothing. It is very persistent in the environment and is found at low levels both in the environment and in the blood of the general U.S. population.


Studies indicate that PFOA can cause developmental and other adverse health effects in laboratory animals.
