"As a result of the lawsuits concerning the PFOA class-action lawsuit, DuPont began to use GenX, a similarly fluorinated compound, as a replacement for polytetrafluoroethylene in the manufacture of fluoropolymers, such as Teflon.[71][72] However, in lab tests on rats, GenX has been shown to cause many of the same health problems as PFOA.[73][74]

The chemicals are manufactured by Chemours, a corporate spin-off of DuPont, in Fayetteville, North Carolina.[75] While PFOA was phased out by 2014, Chemours was already found to be dumping GenX into the Cape Fear River in 2017, with the North Carolina Department of Environmental Quality (NCDEQ) ordering Chemours to halt discharges of all fluorinated compounds on September 5, 2017."
