The purpose of this legislation, known as the PFAS Cleanup Act, is to address the environmental and health issues caused by perfluoroalkyl and polyfluoroalkyl substances (PFAS). These man-made chemicals have been linked to serious health problems and significant costs associated with their removal from drinking water. The Act aims to raise funds to help manage these costs and support efforts to clean up contaminated water systems. Key provisions of the Act include the imposition of a 45 percent excise tax on the sale of PFAS.
