C8, also known as perfluorooctanoic acid, is a toxic and cancerous chemical used to make Teflon. Since the 1950s, a DuPont plant near Parkersburg, West Virginia has been emitting C8 into the air and the Ohio River. According to recent lawsuits, DuPont knew C8 caused cancer in rats as early as 1980, yet covered it up. Now the company will be paying up to settle those suits.
DuPont and its subsidiary Chemours Co. have agreed to pony up $670 million in cash to settle around 3,550 personal injury claims arising from C8 leaks.
