The top state scientific agency charged with protecting Californians from toxic chemicals has proposed adding the “forever chemical” PFOA to the list of substances known to the state to cause cancer in humans under the Safe Drinking Water and Toxic Enforcement Act of 1986, otherwise known as Proposition 65. The California Environmental Protection Agency’s Office of Environmental Health and Hazard Assessment, or OEHHA, said March 19 that PFOA “meets the criteria for listing as known to the state to cause cancer under Proposition 65,” based on the findings of a National Toxicology Program report last year.
