DuPont has never manufactured PFOA, PFOS or firefighting foam, said spokesperson Daniel Turner, referring to two PFAS substances.
“The damage caused by 3M, DuPont, and other manufacturers of PFAS is nothing short of staggering, and without drastic action, California will be dealing with the harms of these toxic chemicals for generations,” Bonta said.
Thursday’s lawsuit was filed in Alameda County, which includes Oakland, and is the first statewide legal action over PFAS contamination.
In June, the US Environmental Protection Agency warned that forever chemicals could be dangerous even at undetectable levels.
The Biden administration is expected to issue the first enforceable drinking water regulations for PFAS in public water systems this year.
