The Orange County Water District and cities throughout the county have filed a joint lawsuit against 3M, DuPont, and other companies, claiming the defendants deliberately contaminated groundwater and water systems throughout the Southern California region.
The plaintiffs—including the cities of Orange, Anaheim, Fullerton, Garden Grove, Santa Ana, and Tustin, along with the water districts of East Orange County, Irvine Ranch, Serrano, and Yorba Linda—allege that the companies contaminated the Orange County Groundwater Basin and the Santa Ana River with polyfluoroalkyl substances (PFAS).
