Per- and Polyfluoroalkyl Substances (PFAS) and Your Health

PFAS banner

CDC and ATSDR are preparing to conduct a health study at multiple U.S. sites to learn more about the health effects of exposure to per- and polyfluoroalkyl substances (PFAS).

PFAS are man-made chemicals that have been used in industry and consumer products worldwide since the 1950s. They have been used in non-stick cookware, water-repellent clothing, stain resistant fabrics and carpets, some cosmetics, some firefighting foams, and products that resist grease, water, and oil.

PFAS are man-made, so there are no natural sources in the environment. However, PFAS can be found near areas where they are manufactured or where products containing PFAS are often used. PFAS can travel long distances, move through soil, seep into groundwater, or be carried through air.

Free resources for clinicians and environmental health professionals, including health assessors.

Exposure to PFAS is an important public health concern. CDC/ATSDR is helping our local, territorial, tribal, state, and Federal partners to address increasing concerns.

CDC/ATSDR ATDSR will be conducting exposure assessments in communities near current or former military installations known to have past or current presence of PFAS in drinking water.
