These two compounds, no longer produced in the US, were used for decades in firefighting foams and are often found in groundwater near military bases, airports, and training facilities for firefighters. Like many other PFAS, they are toxic and generally don’t break down in the environment. The agency made a final determination Jan. 19 that it needs to regulate the two substances under the Safe Drinking Water Act.
