Full report
Sioux Falls is extending its PFAS recovery campaign after the City Council approved participation in proposed settlements with four additional companies in the nationwide aqueous film-forming foam litigation.
The resolution covers proposed class-action settlements with Amerex Corporation, Archroma U.S., Inc., Carrier Global Corporation and Nation Ford Chemical Company in the public-water-systems portion of the multidistrict case, In re: Aqueous Film-Forming Foams Product Liability Litigation. It authorises the city to complete settlement documentation and execute the necessary releases and agreements.
The council also authorised its outside counsel to continue pursuing claims related to PFAS contamination against defendants remaining in the public-water-systems litigation, as well as any other parties that may be liable for damages extending beyond Sioux Falls’ public drinking-water system.
The city attorney described the action as a further stage in the PFAS class-action litigation, covering companies less centrally involved than earlier defendants but still connected to PFAS. He said Sioux Falls had already obtained a substantial recovery through the earlier class action.
That recovery has been placed, by ordinance, in a protected fund for PFAS remediation and for identifying and securing alternative water sources. The city attorney said Sioux Falls had previously closed more than a dozen wells because of PFAS contamination.
During public comment, a resident urged the city to apply lessons from the contamination to its emerging rules for hyperscale data centres, including scrutiny of cooling-system chemicals and disposal arrangements. The council approved the settlement resolution unanimously.
