Per- and polyfluoroalkyl substances (PFAS)

Watch our video to learn how to reduce your exposure to PFAS.

Per- and polyfluoroalkyl substances (known as PFAS) are a large group of manufactured “forever chemicals” — they never disappear from the environment. Some of them also build up in people, wildlife, and the environment (known as bioaccumulation).

PFAS can be found in a wide variety of personal, consumer, and industrial products such as:

While some manufacturers have moved away from PFAS, the alternatives are not always safer. We work with the Department of Health, industry and environmental stakeholders, and community organizations to identify and take actions to phase out the use, release, and exposure to PFAS in Washington. To guide this work, we collaborate with the Department of Health to:

What are the health impacts of PFAS?

While the full scope of health impacts on humans is still not completely understood, experts investigating the impacts on people's health have found probable links to certain cancers, immune system toxicity, reproductive and developmental issues, and many others. Go to the Washington State Department of Health's PFAS page for more information.

How does PFAS get into the environment?

PFAS are water soluble and highly mobile. They can easily contaminate groundwater and be hard to filter out. Since these substances don’t break down naturally, our exposure to PFAS could continue for hundreds or thousands of years.

What products may contain PFAS?

PFAS are used because they are oil- and water-resistant. These properties make them appealing to manufacturers because of their wide application and uses. Some manufacturers have moved away from PFAS but the alternatives are not always safer.

Typical consumer products that can contain PFAS chemicals, such as carpets, non-stick cookware, and waterproof apparel.

This is not an exhaustive list, but here are common examples of products that may contain PFAS:

  • Cosmetics, such as waterproof eyeliner, mascara, or lipsticks.
  • Firefighting foam (otherwise known as AFFF) used to fight fuel-based fires.
  • Food processing equipment, like tubing in ice cream and soda dispensers.
  • Food packaging with grease and waterproof coatings, such as popcorn bags, fast food wrappers, or takeout containers.
  • Nonstick cookware
  • Paints and sealers that promote a smooth finish.
  • Stain- and water-resistant textiles, such as outdoor and upholstered furniture, mattresses, carpets, etc.
  • Waterproof clothes and gear, like raincoats and jackets, or hiking boots and backpacks.
  • Waxes and polishes (for flooring, automobiles, and skis).
