The Department of Natural Resources confirms the presence of PFAS (per- and polyfluoroalkyl substances) in the Peshtigo River and in a nearby culvert.
Residents contacted the DNR in September with concerns after seeing foam on the Peshtigo River below the dam in the city of Peshtigo and foam in a nearby culvert. Foam observed on state waterways and lakes may or may not contain PFAS.
Recent scientific findings indicate that exposure to certain PFAS may have harmful health effects in people. According to the U.S. Environmental Protection Agency (EPA), exposure to some PFAS substances above certain levels may increase the risk of adverse health effects, such as thyroid disease, low birthweights and cancer.
