PFAS and Aquatic Life

As part of the U.S. Environmental Protection Agency’s commitment to safeguard the environment from per- and polyfluoroalkyl substances (PFAS), the agency uses its Clean Water Act authorities to develop recommended water quality criteria and informational benchmarks to help states and authorized Tribes protect aquatic ecosystems from several PFAS.

  • Aquatic Life Criteria - Perfluorooctanoic Acid (PFOA)
  • Aquatic Life Criteria - Perfluorooctane Sulfonate (PFOS)
  • Clean Water Act Aquatic Life Benchmarks for PFAS
