“Forever chemicals” is a popular term used to describe a group of man-made chemicals known as per- and polyfluoroalkyl substances (PFAS). These chemicals are called “forever” because they do not break down easily in the environment or in the human body. PFAS have been used in a wide range of products since the 1940s, including non-stick cookware, water-repellent clothing, stain-resistant fabrics, food packaging and firefighting foams.

Wherever you live and whatever you do, it is almost impossible to completely avoid exposure to forever chemicals. People can be exposed to PFAS through several routes. Drinking water is a common pathway of exposure. PFAS have been used to make water pipes, and contamination of groundwater is common, especially near factories, airports and military bases where these chemicals have been used or produced.  Exposure through consumer products, such as non-stick cookware, stain-resistant carpets and water-repellent clothing, is also difficult to avoid.
