Open sites

Includes Environmental Repair Program (ERP) and Leaking Underground Storage Tank (LUST) sites where contamination has affected soil, groundwater, or other media and the environmental investigation and/or cleanup needs to begin or is underway. This includes sites where cleanup of environmental contamination is ongoing. A "site" is a contamination incident, not a property. A site may be smaller than a property or may include more than one property.

Does not include:

  • spills (immediate cleanup);
  • sites where the DNR required no action;
  • sites not yet mapped; and
  • sites never reported to the DNR.
