Sediment cleanup project is underway at Munger Landing

A sediment cleanup project is underway at Munger Landing, also known as the Clyde Avenue boat launch. This project will protect human health and the environment from contamination left behind from historic industrial discharges.

The U.S. Environmental Protection Agency, Minnesota Pollution Control Agency, & Wisconsin Department of Natural Resources are working together with this project. These agencies and departments are conducting the cleanup through the voluntary Great Lakes Legacy Act program.

J.F. Brennan is also currently under contract to perform the cleanup work. The Munger Landing sediment cleanup project is part of a larger effort to restore and delist the St. Louis River. This is part of the Great Lakes Area of Concern.

The overall project includes the dredging and off-site disposal of approximately 100,000 cubic yards of contaminated sediments across 38 acres. The cleanup will help restore eight acres of aquatic habitat and include replacement of the motorized boat landing. Construction of a new sandy paddle sport launch will take place too.

Completed work on the project includes a dewatering pad constructed at Hallett Dock 7. Installed at Hallett Dock 7 is a water treatment plant, removal of contaminated soil is taking place at boat landing. Approximately 54,000 cubic yards contaminated sediments dredged and removed, and invasive species treatment conducted.

There are several other tasks in motion at Munger Landing. The dredging of contaminated sediments in wetland areas south of Munger Landing. Also water treatment at Hallett Dock 7, and transportation of contaminated sediments to off-site landfills for disposal.

Recommendations to the public are to stay away from the work zones. Be mindful of truck traffic coming in and out of the Munger Landing and Hallett Dock 7 sites. However, Munger Landing will remain closed to the public through the spring of 2024.  Although alternative water access is available at Boy Scout Landing and Rice’s Point.
