The department’s Hazardous Waste Program regulates the management of hazardous waste, oversees the cleanup of contamination, regulates the operation of underground tanks, and oversees removal and cleanup of petroleum storage tanks.

This interactive map allows users to readily access information on 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: Superfund sites, Federal Facilities sites, Resource Conservation and Recovery Act Corrective Action sites, Brownfields/Voluntary Cleanup Program sites, Brownfield Assessments, and Petroleum and Hazardous Substance Storage Tank Facilities.

Users may click on a point or area to review a site information summary, and links to important documents from department files are available. Local governments and utilities are encouraged to utilize the downloadable data layers to assist in permitting, planning and development activities.

Most environmental cleanups are risk-based, which means the site is cleaned up to a level sufficient for its likely future use. Such cleanups may include physical controls, like barriers and caps, or restrictions on future use of the property to prevent exposure to residual contamination. This map is designed to provide information about all clean ups and any related physical controls or property use restrictions. 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, the department's files can be reviewed or copied by making a Sunshine Law request. Contact the Custodian of Records at or call 573-751-3443 or visit for more information.
