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 includes activities where contamination from per- and polyfluoroalkyl substances (PFAS) was confirmed. PFAS data related to open spill incidents are not available at this time. PFAS data are only updated when information is shared with the DNR; therefore, there may be omissions and errors in the data or delays in updating the record with new information.
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.
