PFAS (per- and polyfluoroalkyl substances) are a family of thousands of manufactured chemicals that are found in many everyday items, including nonstick pans, cleaning products, paints, and firefighting foam. PFAS are present in the bloodstream of 98 percent of Americans. Competing studies debate whether PFAS have negative health effects and, if they do, at what levels they are harmful. The federal Environmental Protection Agency has declined to regulate PFAS in drinking water. Meanwhile, some states, including Wisconsin, are choosing to implement regulations independently. Hamilton Consulting Group closely monitors regulatory developments related to PFAS at both the state and federal levels.
