PFAS Exposure Assessment Technical Tools (PEATT)

ATSDR developed the PFAS Exposure Assessment Technical Tools (PEATT) to help State, local, tribal, and territorial health departments conduct PFAS biomonitoring activities, with the assumption that drinking water is the primary source of PFAS exposure. The PEATT includes a protocol for statistically based representative sampling, risk communication materials, questionnaires, and EPA’s water sampling protocol to help characterize PFAS exposure in communities. Upon request, CDC/ATSDR will also provide technical assistance to health departments in developing and carrying out PFAS exposure assessments.

Through a cooperative agreement between CDC/ATSDR and the Association of State and Territorial Health Officials, the Pennsylvania Department of Health and the New York State Department of Health were provided funding to implement and evaluate CDC/ATSDR’s PEATT with the goal of improving the PEATT as a tool for states and territories to use when measuring and evaluating community exposures to PFAS in drinking water. The PEATT implementation and evaluation will ultimately contribute to the overall body of knowledge and refine what is needed to describe exposure in a community.
