PFAS Foam

The words “PFAS foam” can mean one of two things:

  • On lakes and streams, the movement of wind and waves can create foam that floats on top of the water or blows on shore.  This foam may or may not contain PFAS.  Learn more about this kind of foam by clicking on the lake and stream photo, below.
  • PFAS may also be in certain firefighting foams. These foams are most commonly known as Aqueous Film Forming Foam (AFFF) or Class B foam. To learn more about firefighting foam, click on the firefighter, below.
