    • Superfund NPL Boundaries

    Metadata Updated: March 22, 2024

    This data layer contains polygon representations of National Priority List ("Supefund") sites throughout US EPA Region 3. Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA, also known as "Superfund") in response to a growing national concern about the release of hazardous substances from abandoned waste sites. The term “boundary” should be used with caution as it could be interpreted several different ways. The polygons in this file could be property boundaries where the area of contamination is somewhere within the property but not completely encompassing it. They could be “best guess” limits of actual contamination, they could be limits of where remediation work is actually occurring, or several other definitions. For this sort of detail it is best to contact the project manager assigned to the individual facility.
