WLIA 2025 Annual Conference Appleton

Maintaining a publicly available database of hazardous substances or other environmental pollution reported to the Wisconsin Department of Natural Resources (DNR) is one of the required functions of the DNR’s Remediation and Redevelopment (RR) program. The ability to map and display spatial data is key to this work. RR Sites Map is an interactive web mapping application that enables DNR staff members and the public to interact with the spatial information in this database. This presentation will showcase the RR Sites Map and the role of the data in program decision-making and will detail the considerations and process used during the recent migration of the RR Sites Map to a new mapping platform.
