The Great Lakes Legacy Act remediation project on the Buffalo River resumed June 16, and will remove 500,000 cubic yards of contaminated sediment from the river, then replace native aquatic plants to help restore the local ecosystem.
The Great Lakes Legacy Act remediation project on the Buffalo River resumed June 16, and will remove 500,000 cubic yards of contaminated sediment from the river, then replace native aquatic plants to help restore the local ecosystem.
It is all a part of an IISG-funded project investigating the relationship between sediment removal projects and a community’s vulnerability to environmental hazards like natural disasters, pollution, and changing weather patterns. Social vulnerability depends on a lot of factors—average income, education levels, public engagement, and more. Using the Milwaukee Estuary and Grand Calumet Areas of Concern as models, U of I researchers Bethany Cutts and Andrew Greenlee are investigating how these factors change—for better or worse—when a community becomes involved in sediment removal projects.
Work is just beginning, but the project promises a lot of data collection and analysis over the next few years. That is where the students come in. They are all part of the Workshop in Urban Environmental Equity, an inter-departmental course focused on identifying historical demographic changes in the researched regions, as well as developing and piloting interview strategies that Cutts and Greenlee will continue to use well after the course is complete. Beyond being a big step forward for the research project, the workshop provides a unique opportunity for students to be a part of the design and implementation of a multidisciplinary, mixed-method research project—what one student called “the holy grail” of research. Situated at the intersection of social and economic shifts, environmental restoration, planning, and policy, the course and the research can have tremendous benefits for ongoing and future remediation projects and the coastal communities.

It will be a long road to restoration, but this step means those who live and work nearby can expect to see a clean river bottom with a vibrant plant community as early as 2024. For now, efforts are focused on determining the feasibility of cleaning up four river segments: one in Gary, IN and three more in East Chicago, IN, where there is also funding to design a tailored cleanup plan.
Remediation projects are big undertakings. One common strategy, for example, requires contaminated sediment to be dredged, pumped to shore, dried, and trucked off to fill sites certified to handle this kind of waste. At the same time, the water pulled out during dredging has to be treated before it can be returned to the river.
To ensure the success of any new projects in these areas, the EPA is teaming up with the East Chicago Water Management District, the Gary Sanitary District and other local partners to take a closer look at restoration needs. In Gary, planning will likely be completed sometime this year, but it will be another year still before the group announces plans for the stretch flowing through East Chicago. Before any actual cleanup work can begin, though, additional funding and partners will be needed for both projects.
The next few years will also prove significant for two other sections of river. Cleanup efforts at the river’s westernmost end in Hammond, IN are expected to kick off this year. And work on a larger segment of the river just a few miles to the east is expected to wrap up in 2015. There, construction crews have already removed much of the contaminated sediment along the river bed and are now turning their sights to nearby wetlands. Project partners have also begun removing invasive plants along this stretch to make room for native species that will be planted in 2015. Efforts to restore the Grand Calumet River are part of the Great Lakes Legacy Act, the Great Lakes Restoration Initiative, and the Resource Conservation and Recovery Act.

“After nearly three decades of being a black eye of the community, we are thrilled that the Sheboygan River and harbor is being restored to reduce health risks to people, fish, and wildlife, and will greatly enhance opportunities for economic development,” said Adam Payne, Sheboygan County Administrator at a 2012 press event celebrating the project.
Perhaps the biggest boost so far has been to recreation. Dredging the equivalent of 15,000 dump trucks of contaminated sediment left boaters and anglers with a deeper river that is easier to access and navigate. With the contamination gone, the community has also started to see the Sheboygan River as a safe place to spend an afternoon. Just a few months after the project ended, residents reported seeing more and bigger boats navigating in and out of the river’s harbor, and they expect to see even more fishing and boating in the coming years.
“Anytime you have a healthy river going through a community, you have a better quality of life,” said one resident to IISG’s Caitie McCoy and Emily Anderson as part of a series of interviews about how community perceptions of the river had changed.
There is good news for local wildlife too. With the dredging work completed, the Wisconsin Department of Natural Resources and other project partners have begun work to restore native habitats. Recently planted native plants have caught the attention of a variety of species, including cranes and blue birds. With this work done, the Sheboygan River will officially be taken off the list of most polluted places in the Great Lakes. Efforts to clean up and revitalize the Sheboygan River are part of the Great Lakes Legacy Act, the Great Lakes Restoration Initiative, and Superfund.

“A report on stakeholder perceptions of the St Louis River Area of Concern (AOC) and attitudes toward the cleanup and restoration work is now available. This summer, I traveled to the St Louis River with my intern Emily Anderson to perform social science research on community attitudes toward remediation and restoration. The river is located on the border between Duluth, MN and Superior, WI, and is the largest U.S. AOC. The report will help tailor efforts of the Spirit Lake Outreach Team toward local stakeholder needs and interests at the current Great Lakes Legacy Act site in the river, Spirit Lake.Emily provided her thoughts on the experience – ‘Being part of the research team for this project allowed me to experience firsthand how social science contributes to environmental remediation and restoration. Conducting the interviews with Caitie, I met so many intriguing and knowledgeable people; I now see the direct implications that stakeholder input can have for both outreach and project design.’This assessment is part of a larger effort to understand how AOC work influences stakeholder perceptions and use of waterways at a regional scale. A similar report on the Sheboygan River is available and a follow-up report on Sheboygan, post-cleanup, is coming soon.”
Illinois-Indiana Sea Grant’s Caitie McCoy and others have just completed work on a new curriculum for elementary and high school science students.
Helping Hands: Restoration for Healthy Habitats offers lessons and hands-on activities to connect students in the Great Lakes with recent or ongoing cleanup and restoration projects happening in their communities. The range of activities offers new ways to engage students with real-life examples that show environmental science in action.
Teachers interested in having Sea Grant lead the curriculum in their school should contact Caitie McCoy. Caitie can work with the teacher to customize curriculum to meet school-specific needs. The curriculum expands Great Lakes literacy among students, many of whom may become future researchers and educators.
Community leaders in Areas of Concern that would like to help Sea Grant lead or set up an educational program are also encouraged to contact Caitie. The complete curriculum is free to download at the link above.
“Work will start April 22 on a project that will dredge (remove) or cap (isolate from the ecosystem) 1.2 million cubic yards of river bottom sediment contaminated with PAHs, oil & grease, PCBs, and heavy metals like cadmium and copper. Volume-wise, this would fill about 300 Olympic-sized swimming pools. Along with restoration of more than 50 acres of wetland habitat, this work will take place for approximately three years from Kennedy Ave to Cline Ave…This work is funded by US Environmental Protection Agency, Indiana Department of Environment, and Indiana Department of Natural Resources, in partnership with US Fish and Wildlife Service, The Nature Conservancy, Shirley-Heinze Land Trust, Save the Dunes, municipalities, and other local and federal partners. The US Army Corps has also begun dredging in the Indiana Harbor and Ship Canal, and is on track to dredge 300,000 cubic yards through August this year.”
