PFAS (per- and polyfluoroalkyl substances) are manufactured chemicals that are found in many everyday products, including nonstick pans, cleaning products, paints, and firefighting foam. PFAS are present in the bloodstream of 98 percent of Americans. Competing studies debate whether or not PFAS have negative health effects, and, if they do, at what level they are harmful. The federal Environmental Protection Agency has declined to regulate PFAS in drinking water. Meanwhile, some states are choosing to implement regulations independently. Hamilton Consulting closely monitors regulatory developments related to PFAS both at the state and federal level. Click on the links below for more information on PFAS regulations.
