The health and environmental damage linked to certain polyfluoroalkyl substances, or PFAS, has been widely known since the early 2000s with high-profile lawsuits against DuPont related to contamination in drinking water. But the federal government did not start regulating PFAS until the Biden administration.

Environmental lawyers and advocates say the Environmental Protection Agency under President Joe Biden has made progress as the first administration to significantly address PFAS. But industry representatives say the regulations have come too fast for manufacturers to keep up.
