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.
The list below contains locations where a lien or notice of contamination associated with a cleanup activity was recorded at the local registry of deeds. Refer to the BRRTS glossary for definitions of Liens and Notices of Contamination.
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.
