Bureau for Remediation and Redevelopment Tracking System (BRRTS) on the Web

Launch BRRTS on the Web

The Bureau for Remediation and Redevelopment Tracking System (BRRTS) on the Web (BOTW) is the DNR's online database that provides information about contaminated properties and other activities related to the investigation and cleanup of contaminated soil or groundwater in Wisconsin. The database is part of the DNR's Wisconsin Remediation and Redevelopment Database (WRRD), an interlinked system tracking information on different contaminated land activities.

The database includes (but is not limited to) the following contamination data:

  • investigations and cleanups of contaminated soil and/or groundwater;
  • spills;
  • Superfund sites; and
  • DNR funding assistance.

You can also view information from BRRTS on the Web (BOTW) via the RR Program's map-based system, the RR Sites Map.

Bulk data download

A copy of all of the records in the BRRTS on the Web database is available in the zip file below, which contains multiple tab-delimited text files. Additional information can be found in a "read me" file contained within the zip file. The DNR updates this archive file approximately every three months.

Liens/notices of contamination

The following is a list of liens and notices of contamination that have been recorded by the department. The DNR will update this listing approximately every three months. Please see the BOTW glossary of terms for a description.

First-time users

Please use the links listed at the bottom of this page to find database help, a glossary and disclaimers.

Cross-database linkage

The activity detail pages provide links to the solid and hazardous waste database (SHWIMS) and RR Sites Map.

Other databases

The tank registry is a Department of Agriculture, Trade and Consumer Protection (DATCP) database that includes both underground and aboveground tanks that are required to be registered. The database reflects only those tanks that have been registered.

If your search does not produce a tank, this does not guarantee that a tank does not exist on the property. Some tanks, such as heating fuel tanks in the basement of homes are not required to be registered. Some tanks, while required to be registered, have not been registered and therefore will not appear on the database.


If you can't find activities in BRRTS, please contact one of our Regional environmental program associates (EPAs). If you have suggestions regarding BRRTS, please send an email to Danielle Wincentsen.

To contact the DNR staff assigned to an active remediation site, click on the project manager's name on the Activity Details page (you must have an email client installed on your computer, such as Microsoft Outlook). Inquiries regarding closed sites, will be directed to a regional EPA. You may also look for Remediation and Redevelopment staff in the DNR Staff Directory.

Uncontaminated sites

BRRTS includes some locations where an environmental investigation has found contamination with little or no impact to human health and the environment, or no contamination at all. These entries may be found under three different activity types: abandoned containers, no RR action required and some activities under general property.

Health information

For information related to potential health impacts from contaminated sites, please see Wisconsin Department of Health Services (DHS) Environmental Health Resources [exit DNR]. It includes toxic chemical fact sheets.
