Connecting Communities

Communities across the U.S. are responding to the PFAS contamination crisis by organizing and advocating for safe drinking water. This map shows sites with known contamination and where organizations are working for stronger health and environmental protections. Plug into a group working in your community, form a new group, or connect with others facing similar challenges.

Is there a PFAS contamination site near you? Use our interactive map to find out.

  • Each red dot represents a site contaminated with PFAS.
  • Click on a dot to learn more about the site.
  • Click on a state to get information about all sites as well as community groups, health studies, and resources available in that state.

* This map focuses on sites where PFAS have been detected in the environment (groundwater, soil, and surface water), or in drinking water where the contamination is linked to a specific source and not merely the result of testing a water supply system.

  5. Your Turnout Gear and PFOA
    "We are a husband and wife team sharing the discovery of PFOA in firefighter turnout gear used as a water repellent. The manufacturers would not provide the answers we were seeking which led us to the extreme length of securing Dr. Graham Peaslee of Notre Dame University to test new, never-worn gear for us. The results were shocking and led to the discovery of a textile signature precursor that forms PFOA in 'hours to days' along with finding PFOA in the dust of firehouse dust samples. Our issue is complicated further with lies and omissions as the makers of our gear fibers and coatings are immersed in firefighter cancer prevention, but refuses to acknowledge PFOA and now short-chain replacements are a concern."

Some states have conducted their own blood testing to understand people's exposure to PFAS in areas with contaminated drinking water. In the fall of 2019, the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry launched a national health study on PFAS involving multiple communities across the country.

What should you do if you happen to live or work near a PFAS contamination site?

  • Ask your local water supplier if they have tested the drinking water for PFAS and how they have reported (or failed to report) the results to the public.
  • If you have a private well, get your water tested. See our drinking water fact sheet to learn how.
  • Being close to a contamination site does not necessarily mean your drinking water is also contaminated. If you have questions or concerns, contact your state environmental or health department. Also see our list of resources for more information.

Information about contamination sites comes from the PFAS Contamination Site Tracker, a project of the PFAS Project Lab at Northeastern University. The tracker records qualitative and quantitative data from each known site of PFAS contamination, including a timeline of discovery, sources, levels, health impacts, and community and government responses. All data presented in the map were extracted from government websites, news articles, or publicly available documents, and are cited in the tracker.

The Environmental Working Group also maintains a map of PFAS contamination in the US. This map includes additional locations where PFAS were found in drinking water but the point source of contamination is unknown.
