 A bipartisan coalition of the U.S. House of Representatives in July helped pass the PFAS Action Act of 2021, which would establish a national drinking water standard for per- and polyfluoroalkyl substances PFAS contamination. The bill would enable the Environmental Protection Agency EPA to require the cleanup of sites found to be contaminated with two of the most common PFAS chemicals, PFOA and PFOS, set air emission rules surrounding the disposal and incineration of PFAS-laden waste, and place new limits on the introduction of PFAS chemicals into waterways.
