Contaminated Lands Environmental Action Network (CLEAN)

The Contaminated Lands Environmental Action Network (CLEAN) is an inter-linked system providing information on different contaminated land activities in Wisconsin, to assist with the investigation, cleanup and eventual re-use of those lands.

• Contaminated Lands Environmental Action Network (CLEAN) Overview (RR-912) [PDF 328KB]
• Other Statewide Maps (based on CLEAN data - includes contaminated and cleaned up sites, Site Assessment Grants, etc.)
• Want More Information? Subscribe to Remediation & Redevelopment Program electronic newsletters.

In CLEAN, there are two main ways to view information about contaminated land activities:

1. BRRTS on the Web - on-line database
2. RR Sites Map - web-based mapping system

Using either of these two systems, you can find the following information in CLEAN:

BRRTS On The Web (BOTW) is a comprehensive on-line database that provides information on contaminated properties and other activities in Wisconsin. Updated daily. Learn more about BOTW. You can view a graphic display for much of the BRRTS on the Web information via the RR Sites Map. Use BOTW if you want to find: Emergency spills (these are not on RR Sites Map) Sites where DNR has determined no cleanup action is required (these sites are not on RR Sites Map) Properties identified by street address (this is not yet possible in RR Sites Map)

RR Sites Map is a web-based mapping system that allows a user to view different layers of contamination data using a Geographic Information System (GIS) tool. Updated on a regular basis. Learn more about RR Sites Map. You can view a data-only display of RR Sites Map information via BRRTS on the Web. Use RR Sites Map if you want to find: Documents submitted for cleanups that are completed with residual contamination Documents submitted for cleanups that are completed with continuing obligations (land use controls)
