In 2018, EPA began sediment cleanups on Minnesota’s St. Louis River; eight years later

The St. Louis River in Minnesota has seen significant sediment cleanup, with over 1.9 million cubic yards of contamination dealt with. The final phase at Thomson Reservoir employed cutting-edge sediment treatment methods and spanned two years. With successful habitat restoration, communities are now enjoying outdoor activities like swimming and fishing, while further initiatives are planned to enhance the river’s health and remove it from the Great Lakes Area of Concern.
