Solvay Car Ferry Slip

We Energies is partnering with local, state and federal agencies to clean up portions of the Milwaukee Estuary Area of Concern. We Energies is committed to remediating sediment within the Milwaukee Solvay Coke & Gas Site Car Ferry Slip (Solvay Car Ferry Slip), located on the west bank of the Kinnickinnic River, just northeast of the Kinnickinnic Avenue Bridge.

This project will focus on remediating approximately 1 acre of contaminated sediment associated with 120-plus years of industrial operation on the property, including manufactured gas and coke production, rail car ferry operations, electric railroad operation, blast furnace operation for iron production, and hide tanning. Sediment remediation includes placing an engineered cap (consisting of a minimum 2 feet of clean sand and armor stone) that will isolate contaminated sediments and allow historic infrastructure to remain in place, reducing the impact of the remediation activities on the aquatic habitat and local community. A subaqueous sheet pile wall will contain and maintain the integrity of the engineered cap.

By addressing contaminated sediment, water quality will improve, resulting in safer public use of the waterway and improved wildlife habitat and fisheries in this area. Final remedial design is complete and has been approved by Wisconsin Department of Natural Resources (WDNR). We Energies contractors Ramboll and Michels Construction Inc. will complete the remedial action work that began in early October 2024 and is expected to continue through December 2024. Construction activities are planned for Mondays through Fridays, from approximately 6:30 a.m. to 5 p.m.
