PFAS

What are PFAS?

Perfluoroalkyl and polyfluoroalkyl substances (PFAS), such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are part of a group of chemicals used globally during the past century in manufacturing, firefighting and thousands of common household and other consumer products.

In recent years, experts have become increasingly concerned by the potential effects of high concentrations of PFAS on human health. Learn more about PFAS at www.michigan.gov/pfasresponse.

Drinking Water Testing

The State of Michigan is working proactively to identify locations where PFAS may be present as a contaminant. The Michigan Department of Environmental Quality is testing all of the public systems in Michigan this year, and many already have been tested.

PFAS and Health

Scientists are still learning about the health effects of exposures to mixtures of PFAS. Although more research is needed, some studies in people have shown that certain PFAS may:

  • affect growth, learning, and behavior of infants and older children
  • lower a woman’s chance of getting pregnant
  • interfere with the body’s natural hormones
  • increase cholesterol levels
  • affect the immune system
  • increase the risk of certain types of cancer

More information about PFAS and health is available from the State of Michigan and the CDC.
