While waiting for federal action, states have taken their own steps to protect residents against the risk of PFAS exposure.

At least 28 states have laws targeting PFAS in various uses, such as in food packaging and carpets. About a dozen have drinking water standards for PFAS. But relying on state laws creates a patchwork of regulations, which places burdens on businesses and consumers to navigate regulatory nuances across state lines.

Based on current scientific understanding, most people are exposed to PFAS primarily through their diet, though drinking water and airborne exposures may be significant among some people, especially if they live near known PFAS-related industries or contamination.

The best ways to protect yourself and your family from risks associated with PFAS are to educate yourself about potential sources of exposure.

Products labeled as water- or stain-resistant have a good chance of containing PFAS. When possible, check the ingredients on products you buy and watch for chemical names containing “fluor-.” Specific trade names, such as Teflon and Gore-Tex, are also likely to contain PFAS.

Check whether there are sources of contamination near you, such as in drinking water or PFAS-related industries in the area. Strategies for monitoring and reporting PFAS contamination vary by location and PFAS source, so the absence of readily available information does not necessarily mean the region is free of PFAS problems.

For additional information about PFAS, check out the Agency for Toxic Substances and Disease Registry, EPA and U.S. Centers for Disease Control and Prevention websites, or contact your state or local public health department.

If you believe you have been exposed to PFAS and are concerned about your health, contact your health care provider. The National Academies of Sciences, Engineering, and Medicine have published guidance on PFAS exposure, testing and clinical follow-up, which includes information to help health care professionals understand monitoring and clinical implications of PFAS exposure.
