Obama’s EPA today took action on PFOA contamination by requiring DuPont and Chemours to take additional actions to reduce C8 exposure in drinking water for residents in Ohio and West Virginia living near Washington Works.
Today’s action amends a 2009 consent order and establishes a new action level of 0.07 parts per billion which triggers the temporary provision of an alternate source of drinking water by DuPont and Chemours until a permanent alternative drinking water supply is provided. Last May the EPA established a temporary action level of 0.07 parts per billion – down from the 2009 level of 0.40 parts per billion causing a need for Vienna’s water to be temporarily replaced until a filtration facility could be constructed at DuPont’s cost.
The latest order makes that temporary action level permanent and expands the geographic areas to be investigated for C8 contamination. EPA says the new Lifetime Health Advisory was set to be protective of human health.
