PFAS and Your Health

Per- and Polyfluoroalkyl Substances (PFAS) and Your Health

CDC/ATSDR is soliciting research applications to conduct a multi-site study on the human health effects of exposures to PFAS through drinking water.

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.
