"We worked with EPA to agree to a consent decree and will continue to take action to address the legacy deposition that have contributed to many of the exceedances," Thom Sueta, a spokesperson for Chemours, said in a statement. Chemours has a permit from the West Virginia Dept. of Environmental Protection to discharge industrial process water and stormwater into the Ohio River and its tributaries. However, EPA says the levels of some PFAS in those discharges exceed allowable amounts on various dates between September 2018 and March 2023.
