This interactive map allows users to access information about site investigations and cleanups, as well as certain regulated sites within a specific community or area. The map contains information about the following types of sites in Missouri:
- Federal Facilities
- Hazardous Waste Treatment, Storage and Disposal Facilities
- Brownfields/ Voluntary Cleanup Program
- Brownfield Assessments
- Petroleum and Hazardous Substance Storage Tank Facilities
Most environmental cleanups are risk-based, meaning the site is cleaned up to a specific level, such as residential or non-residential, based partly on its likely future use. Risk-based corrective action, or cleanup, may include physical controls, like barriers and caps, or specific activity and use limitations on the property to prevent exposure to any remaining contamination. This map is designed to provide information about all cleanups and any related tools and controls put in place to ensure long-term protection. Users may click on a point or area to review a site information summary, which contains links to documents the department currently has available in electronic form. Developers, local governments and utilities are encouraged to use the downloadable data layers to assist in permitting, planning and development activities.
The department’s goal in making site information easily accessible is to provide a transparent, consistent information resource that helps ensure property is used safely in Missouri. If additional data is required, you can learn more about specific properties in Missouri undergoing long-term stewardship on the department's Closed and Long-Term Stewardship (LTS) Sites webpage. You can also obtain copies the department's files by submitting an Open Records/ Sunshine Law Request.
