The Houston-based Inhance Technologies filed a petition in the 5th U.S. Circuit Court of Appeals on Thursday, less than a week after EPA sent Inhance orders to stop making nine likely harmful PFAS, or per- and polyfluoroalkyl substances, as a result of its fluorination process.
Independent testing by Public Employees for Environmental Responsibility first linked PFAS contamination to Inhance’s fluorination process in December 2020.
