PFAS Information

There are a variety of ways that people can be exposed to these chemicals and at different levels of exposure. For example, people can be exposed to low levels of PFAS through food, which can become contaminated through: contaminated soil and water used to grow the food, food packaging containing PFAS, and equipment that used PFAS during food processing.

People can also be exposed to PFAS chemicals if they are released during normal use, biodegradation, or disposal of consumer products that contain PFAS.

Drinking water can be a source of exposure in communities where these chemicals have contaminated water supplies. Such contamination is typically localized and associated with a specific facility, for example, an industrial facility where PFAS were produced or used to manufacture other products, or an oil refinery, airfield or other location at which PFAS were used for firefighting (Source: United States Environmental Protection Agency).
