the U.S. Environmental Protection Agency (EPA) has been actively involved in addressing per- and polyfluoroalkyl substances (PFAS). PFAS are a group of human-made chemicals used in various industrial and consumer products due to their water- and grease-resistant properties. These chemicals have been found in soil, water, and air, and can persist in the environment for a long time.

The EPA has been researching the potential health and environmental effects of PFAS and has taken steps to address their presence and potential risks. Here are some key actions and statements by the EPA regarding PFAS:

Health Advisories: The EPA has issued health advisories for two PFAS compounds, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), which are no longer manufactured in the United States but have been detected in drinking water supplies.The health advisories provide guidance on acceptable levels of these chemicals in drinking water to protect public health.

Research and Monitoring: The EPA has been conducting research to understand the health effects of various PFAS compounds and to develop methods for detecting and measuring these chemicals in different environmental media. The agency is also monitoring PFAS levels in drinking water systems across the country.

Regulatory Actions: The EPA has taken steps to address PFAS contamination. In 2019, the agency issued a PFAS Action Plan outlining several actions, including the development of drinking water regulations for PFOA and PFOS, considering listing certain PFAS as hazardous substances, and exploring options for restricting PFAS in imported products. Additionally, the EPA has proposed the addition of certain PFAS to the Toxics Release Inventory, which would require reporting of releases of these substances.

Enforcement and Cleanup: The EPA has been using its enforcement authorities to address PFAS contamination. The agency has initiated enforcement actions against companies for PFAS-related violations and has been working with states and other partners to clean up contaminated sites.
