The Agency for Toxic Substances and Disease Registry (ATSDR), based in Atlanta, Georgia, is a federal public health agency of the U.S. Department of Health and Human Services. ATSDR protects communities from harmful health effects related to exposure to natural and man-made hazardous substances. We do this by responding to environmental health emergencies; investigating emerging environmental health threats; conducting research on the health impacts of hazardous waste sites; and building capabilities of and providing actionable guidance to state and local health partners.

Introducing CDC/ATSDR’s PFAS Blood Level Estimation Tool
The PFAS Blood Level Estimation Tool (“the tool”) was created to help individuals who have consumed PFAS-contaminated drinking water and who have information about the levels of PFAS in their water estimate their PFAS blood levels. The tool is a user-friendly, web-based estimator for the public, housed on the ATSDR website.
