On April 12, 2022, a Wisconsin judge ruled in the case of Wisconsin Manufacturers & Commerce, Inc. and Leather Rich, Inc. v. WDNR, (Waukesha County Case 2021CV000342) that the WDNR lacks the authority to regulate PFAS chemicals because the Wisconsin Legislature has not established regulatory standards for them. According to the lawsuit, Leather Rich, Inc. entered into a voluntary WDNR environmental cleanup program in 2019, and the following year WDNR indicated that the businesses enrolled in the program were required to test for emerging contaminants, including PFAS.
