Per-and Polyfluoroalkyl Substances: The Facts

What are PFAS?

PFAS are a group of man made chemicals that includes PFOA, PFOS, GenX and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body - meaning they don't break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects.
