WASHINGTON, D.C. — Today, as a part of the U.S. Environmental Protection Agency (EPA)'s PFAS Strategic Roadmap, the agency issued the first in a series of Toxic Substances Control Act (TSCA) test orders to require companies to conduct and submit testing on per- and polyfluoroalkyl substances (PFAS). When EPA announced its Strategic Roadmap to confront PFAS contamination nationwide, the agency also released the National PFAS Testing Strategy to help identify PFAS data needs and require testing to fill those gaps.
