Remediation And Redevelopment Database Enhancements Available Now

A newly designed and enhanced Bureau of Remediation and Redevelopment Database Tracking System (BRRTS) application is now available. Update your existing bookmarks to the new web address for quick access to the information.  

BRRTS is a go-to source for publicly available information about reports of potential contamination, property with contamination, cleanup activities and redevelopment activities in Wisconsin.  

Updates to BRRTS were planned to transition the application to different technology platform. As part of the process, the DNR asked internal and external stakeholders to suggest improvements to the tool. Recommendations included updating the user interface and improving search features. The DNR completed the first phase of improvements which include the following highlights: 

  • The ability to search by the Consultant Company and Historical Waste Fill fields 
  • Improved options for viewing search results  
  • Buttons to easily navigate to supplemental datasets, maps and location details 
  • Faster page scrolling on the Activity Details Page  
  • And more! 

Additional enhancements are anticipated for the Fall of 2025.  

Contact Sonya.Rowe@wisconsin.gov with questions or suggestions.

Public Comment Period: 5-year Review For Sauk County Landfill Superfund Site

The Wisconsin Department of Natural Resources (DNR) and U.S. Environmental Protection Agency (EPA) invites the public to share information about the Sauk County landfill and the ongoing cleanup process as part of a 5-year review. The review, required under federal law, ensures the continued effectiveness of remedies at the site. This is the sixth review since the completions of construction work in the 1990s. The last 5-year review was competed in 2020.

The landfill operated from 1973 to 1983 and received municipal, commercial and industrial wastes. To address groundwater contamination from volatile organic compounds (VOCs) originating from materials disposed of in the landfill, the cleanup remedies included capping the landfill, landfill gas collection and testing of private water supply wells.

Today, Sauk County maintains the landfill cap and fencing to prevent direct contact to waste material. Monitoring of groundwater wells evaluate contaminant migration and groundwater use restrictions in the immediate area protect the public from using contaminated groundwater.

The DNR invites interested parties to provide information that might be important to the 5-year review of the Sauk County Landfill Superfund Site by May 16, 2025, to one of the contacts listed below.

  • Luke Lampo, DNR Hydrogeologist, Luke.Lampo@wisconsin.gov, 608-206-5809, 3911 Fish Hatchery Rd., Fitchburg, WI 53711.
  • Nabil Fayoumi, EPA Remedial Project Manager, Fayoumi.Nabil@epa.gov, 312-886-6840, 77 W. Jackson Blvd., Chicago, IL 60604.

To learn about the Sauk County Landfill site or see previous 5-year reviews, visit the Bureau for Remediation and Redevelopment Tracking System (BRRTS) on the Web (BOTW) at dnr.wisconsin.gov and search for “BRRTS.” Launch BOTW and enter 02-57-001004 into the “BRRTS No.” field.

Additional information can be found on the EPA Sauk County Landfill webpage.

Now Available: Updated Publication Wisconsin Vapor Quick Look-Up Table Indoor Air Vapor Action Levels And Vapor Risk Screening Levels (RR-0136)

The publication Guidance: Wisconsin Vapor Quick Look-Up Table Indoor Air Vapor Action Levels and Vapor Risk Screening Levels (RR-0136) is now updated and available on the DNR website. The U.S. EPA updated toxicity information for 1,1-dichloroethylene (1,1-DCE) in November 2024 by changing from U.S. EPA’s Integrated Risk Information System (IRIS) chronic inhalation reference concentration (RfC) to the Agency for Toxic Substances and Disease Registry (ATSDR) RfC for this chemical. The update decreased the VALs and VRSLs for 1,1-DCE.   

The purpose of this look-up table is to list volatile organic compounds frequently encountered at cleanup sites in Wisconsin. Consultants should compare vapor data for open sites to the updated table for potential additional actions. Vapor data for chemicals not listed on RR-0136 should accessed via the U.S. Environmental Protection Agency Vapor Intrusion Screening Level (VISL) Calculator; instructions on using VISL are included in RR-0136.    

Additional documents and guidance from the Remediation and Redevelopment Program may be found using the search tools available on the publications and forms webpage. 

Questions regarding this document may be submitted to Jennifer Borski at Jennifer.Borski@wisconsin.gov.
