The Environmental Council of States (ECOS) has published a white paper presenting the efforts and considerations being made by U.S. states in regulatory activities regarding per- and polyfluoroalkyl substances (PFAS).

The document provides an overview of states with and without PFAS guidelines as well as set levels and to which media they apply. It further analyzes differences in each state, including the processes and approaches taken for risk assessment and management. State agencies were also surveyed, and the paper summarizes key considerations and unanswered questions they have that will affect the development of their future PFAS guidelines.

The paper concludes that “regulators need more transparency about the uses of existing PFAS, the ongoing development of new PFAS chemicals by industry, and PFAS approval by the EPA under statutes like the Toxic Substances Control Act (TSCA).” Given the lack of federal oversight on the issue, states are working to independently regulate PFAS, and “it is critical to coordinate with and learn from other states that have established and are establishing their own guidelines.”
