What Everyone Should Know about Per and Polyfluoroalkyl Substances (PFAS)

PFAS are human-made chemicals that have been used since the 1950s in thousands of consumers and industrial products. Because they do not break down easily, they can persist in the environment and in our bodies for many years and may be found in drinking water, food, and everyday items. Learn more about PFAS, potential health concerns, and steps you can take to reduce exposure and protect your family.
