Tribal PFAS Working Group

What is PFAS?
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that were developed in the 1940s. PFAS are found in many elements within our environment including food packaging, commercial household products, and firefighting foam, among others. PFAS are persistent chemicals and may accumulate in the human body for a long time. PFAS remain in the environment for a long period of time due to their strong chemical bonds. PFAS pose a risk to tribal lifeways, resources, and traditional foods.

The Tribal PFAS Working Group (TPWG) formed in April 2020 to help address and reduce PFAS in Indian Country. The working group is comprised of members of the National Tribal Water Council, Tribal Science Council, National Tribal Toxics Council, Tribal Waste and Response Steering Committee, and Tribal Pesticide Program Council.

The working group holds monthly meetings to discuss various activities that would help achieve its objectives and priorities, and at the same time learning and understanding the implications of PFAS in tribal communities. The TPWG developed an informational flyer providing basic information on PFAS and where it can be found (to access click HERE).
