The Buffalo River was subjected to a great deal of industrial contamination years ago. Efforts at pollution prevention and cleanup have helped to rehabilitate the water way, but a great deal of contamination still exists in the sediment at the bottom of the river. These contaminants can still have a negative effect on economic, social, and environmental uses of the river, but an ongoing collaboration between a number of agencies is working right now to clean up and restore the river bottom.

The U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, Buffalo Niagara RIVERKEEPER, Honeywell and several other affiliated public and private entities have teamed up to complete a two-year dredging project that will remove 1.2 million cubic yards of contaminated sediment, which will provide a clean and supportive environment for local, native species to flourish.

Part of the work is being performed under the Great Lakes Legacy Act, which revitalizes once-thriving waterways through sediment cleanups and restoration. The act requires at least 35 percent of the project cost to come from non-federal partners. IISG’s Environmental Social Scientist Caitie McCoy has provided expertise for the project. For example, she prepared the publication The Buffalo River Restoration Project: Frequently Asked Questions. The FAQ gives detailed information on the Buffalo River Restoration Project, including the project’s timeframe, funding, impact, and more.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
