The Environmental Council of the States (ECOS) prepared a White Paper “Processes & Considerations for Setting State PFAS Standards.” (ECOS PFAS Standards-White Paper-Feb_2020)
Text copied from the Executive Summary:
ECOS “…. in 2019 compiled information on state PFAS standards, advisories, and guidance values…. Sharing data and regulatory approaches will help federal, state, and international authorities avoid unnecessary duplication of efforts, as well as understand and communicate about differences in guidelines. This paper outlines ECOS’ findings on state efforts and considerations for future regulatory activities on PFAS.”
