20. What can residents, businesses, and visitors can do to prevent exposure to PFAS?

PFAS are slow to break down in the environment, and therefore are often found in food and the environment (soil, water). It is unlikely that you can avoid all PFAS exposure. However, you can take the following actions to limit your exposure to PFAS:

  • Read product labels and avoid using products that contain PFAS
  • Rinse home-grown produce with water prior to eating
  • If your private (domestic) well drinking water contains PFAS above the MassDEP PFAS6 MCL, consider using a different or treated water source for the following uses:
    • Drinking
    • Food preparation and cooking
    • Brushing teeth
    • Preparing infant formula
    • Filling swimming pools
