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.

* 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.

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.

If you know about a contamination site that is not shown on the map, fill out this form to have it added. Check back for updates!

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.
