Wisconsin Remediation and Redevelopment Database (WRRD)

The Wisconsin Remediation and Redevelopment Database (WRRD) (formerly called the Contaminated Lands Environmental Action Network, or CLEAN) is an interlinked system providing information on different contaminated land activities in Wisconsin, to assist with the investigation, cleanup and eventual reuse of those lands.

There are two main ways to view information about contaminated land activities.

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

BRRTS On The Web (BOTW) is a comprehensive online database that provides information on contaminated properties and other activities in Wisconsin. Updated daily.

You can view a graphic display for much of the information on BOTW via the 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.

You can view the data associated with sites found on RR Sites Map via BOTW.

Use either system to find the following information.

  • Cleanups still underway
  • Cleanups that are completed
  • Financial assistance (e.g., DNR loans and grants)
  • Liability incentives (e.g., liability clarifications and limitations)
  • Other redevelopment information (i.e., brownfields)
  • Continuing obligations (other states/agencies use terms such as "institutional control" or "land use control")
  • Documents submitted for cleanups that are completed with residual contamination
  • Documents submitted for cleanups that are completed with continuing obligations

Use BOTW if you want to find:

  • emergency spills (these are not on RR Sites Map);
  • sites where the DNR has determined no cleanup action is required (these sites are not on RR Sites Map); and
  • properties identified by street address.
