Santa Clara County filed a lawsuit claiming DuPont, 3M and other companies knowingly contaminated local drinking water with PFAS, also called “forever chemicals.” PFAS exposure is linked to cancer, immune system damage and developmental issues. A 2023 study found PFAS in nearly half of U.S. tap water.
The lawsuit alleges PFAS entered water supplies through firefighting foams used in training, with contamination detected in multiple cities and wildlife in the San Francisco Bay.
“DuPont transferred all women out of work assignments with potential exposure to PFOA, but concealed its pregnancy-related study from the workers, the EPA and the public.”
