California Sues PFAS Manufacturers
On November 10, 2022, California filed suit in California Superior Court against the manufacturers of per- and polyfluoroalkyl substances (PFAS) “for endangering public health, causing irreparable harm to the state’s natural resources, and engaging in a widespread campaign to deceive the public.” According to California Attorney General Rob Bonta’s November 10, 2022, press release, California “alleges that these manufacturers, including 3M and DuPont, knew or should have known that PFAS are toxic and harmful to human health and the environment, yet continued to produce them for mass use and concealed their harms from the public.” California claims that as a result, “these toxic ‘forever chemicals’ are pervasive across California’s bays, lakes, streams, and rivers; in its fish, wildlife, and soil; and in the bloodstream of 98% of Californians.” The complaint claims that the manufacturers “created and/or contributed to a public nuisance, harmed and destroyed natural resources, marketed defective products, failed to provide adequate warnings concerning the use of their products, and engaged in unlawful business practices.”
The press release states that the lawsuit concerns seven common PFAS that have been detected in drinking water supplies, surface waters, and groundwater in California: perfluorooctanoic acid (PFOA); perfluorooctanesulfonic acid (PFOS); perfluorobutanesulfonic acid (PFBS); perfluorohexanesulfonic acid (PFHxS); perfluorohexanoic acid (PFHxA); perfluoroheptanoic acid (PFHpA); and perfluorononanoic acid (PFNA). California requests statewide treatment and destruction of PFAS, including, but not limited to, the treatment of drinking water by regulated water systems; water drawn from private wells and unregulated systems used for drinking water and irrigation; and water from other wastewater treatment plants and systems. California also seeks payment of funds necessary to mitigate the impacts to human health and the environment through environmental testing, medical monitoring, public noticing, replacement water (for period between testing and installation of treatment), and safe disposal and destruction.
