    The Interactive Map:

    Military Site Specific Map:

    Polyfluoroalkyl substances – known as PFAS  Insights & Resources

    Quoting from INFO on Interactive Map:

    PFAS Contamination in the U.S. (August 17, 2023)

    For all water systems with a detection of PFOS, PFOA or another PFAS, a maximum concentration for each PFAS and a maximum total PFAS concentration is displayed. The maximum levels listed are from a single point in time and do not reflect whether a water system has changed sources or is treating the water to reduce PFAS levels.

    All locations represented on the map are approximate and intended to portray the general area of a contamination site or a community water system. Locations were mapped using the best data available from official records, including data provided by tests of public drinking water systems, the Unregulated Contaminant Monitoring Rule, the Safe Drinking Water Information System, the Department of Defense report Addressing Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA),” among others.

    Levels listed are for the range of the total of all PFAS detected at the time of the tests and do not reflect whether a water system is treating the water to reduce levels.

    Data on contaminated water system, industrial and military sites was current as of August 2023.
