Today, the U.S. Environmental Protection Agency (EPA) is announcing three actions to protect communities and the environment from per- and polyfluoroalkyl substances (PFAS) in our nation’s waters. The actions announced today advance progress under the Biden-⁠Harris Administration’s Plan to Combat PFAS Pollution by improving methods to detect PFAS in water, reducing PFAS discharges into our nation’s waters, and protecting fish and aquatic ecosystems from PFAS. These efforts complement the historic investment of $10 billion to address PFAS and emerging contaminants secured under the Bipartisan Infrastructure Law.
