New Tools from EPA to Test and Treat Additional PFAS in Drinking Water

The U.S. Environmental Protection Agency (EPA) announced an updated and validated way to test for an additional four per- and polyfluoroalkyl substances (PFAS) in drinking water, including the GenX chemical, hexafluoropropylene oxide dimer acid (HFPO-DA).

The updated tools are part of EPA’s efforts to increase the amount of research and information that is publicly available for chemicals in the PFAS family.
