PFAS-free firefighting foams: Are they safer?

  • In the 1960s, researchers from the U.S. Navy Research Laboratory began testing a new class of firefighting foam that could rapidly extinguish fuel fires.
  • In fact, the Environmental Working Group estimates that PFAS chemicals are detectable in all major U.S. water supplies.
  • Making sure these new foams actually are safer for the environment and health than the ones they replace is key to ensuring we don’t end up in the same place 50 years from now—with widespread contamination from a new set of toxic chemicals—say environmental health experts.
