REMEDIATION AND REDEVELOPMENT DATABASE - BRRTS


The Wisconsin Department of Natural Resources (DNR) maintains a searchable database of information on activities related to property assessments and investigations, contamination, cleanup or redevelopment activities.

SUPPLEMENTAL DATASETS

The following pages provide real-time data from the Bureau for Remediation and Redevelopment Tracking System (BRRTS) database.
Action Code Reference List Coming Soon
Lists action codes, names, and descriptions used in BRRTS to track activities at remediation and redevelopment sites.
Bulk Data Download Coming Soon
Downloadable zip file containing publicly available information in BRRTS.
Dry Cleaner Facility Listing Coming Soon
Lists facilities that have a reported historical use as a dry cleaning facility. This is only a listing of known remediation sites with a cleanup of contamination that may be related to dry cleaning substances. Some of the facilities are also enrolled in the Dry Cleaner Environmental Response Program (DERP). The DNR does not regulate or license dry cleaning facilities. The “status” provided in this list only refers to cleanup activities and not the operation of the facility.
Environmental Services Contractor List
Lists self-identified environmental service providers, including environmental consultants and contractors. The DNR does not endorse nor certify the qualifications of the listed entities. To be added to this list, please email Jenny Meyer.
Great Lakes Areas of Concern
The U.S.-Canada Great Lakes Water Quality Agreement [exit DNR] defines an Area of Concern (AOC) as "a geographic area designated by the Parties where significant impairment of beneficial uses has occurred as a result of human activities at the local level." An AOC is a location that has experienced environmental degradation. The U.S. Environmental Protection Agency (EPA) and other state and federal agencies are working to restore AOCs in the Great Lakes basin, five of which are in Wisconsin.
Liens/Notices of Contamination Coming Soon
Lists locations where a lien or notice of contamination associated with a cleanup activity was recorded at the local registry of deeds.
Open Spill Incidents
Lists open incidents currently being investigated and evaluated.
PFAS Site Listing Coming Soon
Lists activities where contamination from per- and polyfluoroalkyl substances (PFAS) was confirmed. PFAS data related to open spill incidents is not available at this time.
State-Funded Response Cleanups Coming Soon
Lists cleanup activities where the DNR took actions using the state's Environmental Fund. The state may take action when the responsible party is unknown or is unable or unwilling to pay for the necessary investigation and/or remediation. The list does not include locations where DNR provided temporary emergency drinking water or DNR responses to emergency spills or abandoned containers. The data are updated following the end of the state fiscal year.

BRRTS data comes from various sources, both internal and external to the DNR. There may be omissions and errors in the data and delays in updating new information.
