Superfund Sites Targeted for Immediate, Intense Action

This is a list of sites from across the United States that Acting Administrator Wheeler has targeted for immediate and intense attention. This list is in direct response to the Superfund Task Force Recommendations, issued July 25, 2017, calling for this list.

In developing this list, EPA considered sites that can benefit from Acting Administrator Wheeler's direct engagement and have identifiable actions to protect human health and the environment. These are sites requiring timely resolution of specific issues to expedite cleanup and redevelopment efforts.  The list is designed to spur action at sites where opportunities exist to act quickly and comprehensively. The Acting Administrator will receive regular updates on each of these sites.

The list:

  • Is intended to be dynamic. Sites will move on and off the list as appropriate. At times, there may be more or fewer sites based on where the Administrator’s attention and focus is most needed.
  • There is no commitment of additional funding associated with a site’s inclusion on the list.
  • Is presented in order by EPA region.

EPA remains dedicated to addressing risks at all Superfund sites, not just those on the list. The Task Force Recommendations are aimed at expediting cleanup at all Superfund sites and the Acting Administrator has continued to set the expectation that there will be a renewed focus on accelerating work and progress at all Superfund sites across the country.

As of July 31, 2018, the list is:
