Chemours Seeks Judicial Review of GenX Health Notice | News, Sports, Jobs


PARKERSBURG — Chemours is asking a federal court to review the Environmental Protection Agency’s final health advisory on a chemical used in the Teflon manufacturing process at the Washington Works plant.

According to a company statement, the advice issued in June was based on an assessment with “numerous material scientific flaws, including its failure to incorporate available and highly relevant peer-reviewed studies and that it grossly overestimates the potential for associated risk” hexafluoropropylene oxide dimer acid (HFPO-DA).

HFPO-DA and its ammonium salt are used in a patented technology platform sometimes referred to by its trade name GenX. The platform was developed by DuPont as a replacement for what is known as “forever chemicals”, including C8.

A scientific panel formed following the settlement of a lawsuit over the presence of C8 in local water supplies has discovered possible links between C8 and half a dozen diseases in humans. It was replaced by GenX in 2012, but this substance has since been detected in surface water, groundwater, drinking water, rainwater and air emissions.

The health advisory for GenX chemicals is 10 parts per trillion. An interim health goal of 140 parts per trillion was issued by the state of North Carolina in 2017.
