​​​Per- and Polyfluoroalykyl Substances

Per- and polyfluoroalykyl substances (PFAS) are chemical contaminants of growing concern due to their persistence in the environment and ability to bioaccummulate in animals and people. Many communities are grappling with environmental PFAS contamination due to specialized fire suppression materials (such as aqueous film forming foams, or AFFF) current and past industrial uses and the potential for human exposures.

PFAS Exposure Assessment Technical Tools​​​​​​

To assist, NCEH/ATSDR created the PFAS Exposure Assessment Technical Tools (PEATT). The PEATT is intended to help state, local, tribal, and territorial health departments conduct PFAS biomonitoring activities should they choose to. The PEATT includes: ​

  • ​Biomonitoring sampling and analysis protocol
  • Exposure and health effects question bank
  • Biomonitoring letters of interpretation, consent, assent
  • Risk communication materials
  • Laboratory biomonitoring sample collection and analysis protocols
  • Recommended EPA water sampling protocol

To request a copy of the PEATT please send a request to PFAS@cdc.g​ov.
