February 2024 TSCA PFAS Workshop
On February 13-15, 2024, EPA held a workshop with representatives from stakeholder organizations at the National Institutes of Health (NIH) Neurosciences Building in Bethesda, Maryland. The purpose of this meeting was to obtain stakeholder input on issues related to the National PFAS Testing Strategy, associated Toxic Substances Control Act (TSCA) per- and polyfluoroalkyl substances (PFAS) test orders, scientific and methodological challenges in testing and potential solutions, and encouraging PFAS alternatives.
