The 2.6-mile section of the river, located near the Port of Monroe, Michigan’s only port on Lake Erie, was contaminated with PCBs and lead from nearby manufacturing. Multiple cleanups starting in 1997 have removed a total of 135,000 cubic yards of contaminated sediment.
The River Raisin was once home to American lotus beds and sturgeon populations. Pollution drove these species away, but the cleanup will restore the river and provide a healthy habitat for native fish, birds, and plants.
Dredging was then followed by a process known as capping that involves the installation of sand, clay, and stones over any residual contaminated sediment to create a barrier with the rest of the waterbody. This strategy is commonly used in combination with dredging.
“Contractors worked 24 hours a day, seven days a week over the last month or so to get the remedial cap installed,” Ben Wegleitner, IISG sediment remediation outreach specialist. “They wanted to get the top layer of armor stone in place before the next large freighter came into port.”
Wegleitner narrated the video above.
In the coming weeks, the equipment and the sediment processing area will go through a complete decontamination procedure before being removed from the site.
The area will continue to go through extensive monitoring before it’s officially delisted from the Areas of Concern list through a process that can take years.
“This site has been through a lot in the last 30 years,” Wegleitner said. “Without a doubt, this is a major milestone.”

Schoolchildren once again got the chance to explore and learn from the environmentally remarkable Grand Calumet River at the remediated Roxana Marsh in northwest Indiana.
Seventy students from fourth and sixth grades atHarrison,McKinleyandCarrie Gosch elementaryschools worked one-on-one with scientists and experts doing activities like fish identification, macroinvertebrate sampling, bird watching, and tree planting. The mayor of East ChicagoAnthony Copeland even stopped by and helped the students plant a swamp white oak, a tree native to the area.
For a long time, the Grand Cal was referred to as the most polluted river in America. Through Great Lakes Legacy Act funding, almost 2 million cubic yards of river and wetland sediment have been removed or capped and 84 acres of habitat have been restored, including Roxana Marsh.
“It builds pride-in-place,” said Caitie Nigrelli, IISG environmental social scientist who’s been organizing the event every year. “It also helps encourage kids to take part in future stewardship efforts.”
Carrie Gosch Elementary sixth-grader Gerald Lewis was impressed by all the birds and insects and fish he saw.
“I didn’t know we were going to see this much, like eggs on the ground and stuff,” Lewis said. “And we saw some of the fish that was polluted by the oil.”
But his new-found interest in the environment didn’t end there. It made him want to do something about it.
“I felt sad at first when they showed us the fish that was getting hurt and killed,” Lewis said. “That made me want to think, like when I get older, I can help them.”

Lincoln Park and I are both coming to the end of an exciting chapter this fall. As my internship with
IISG comes to a close, Phase 2 sediment remediation work in in Lincoln Park in Milwaukee is also finishing up.
Four years and more than 170,000 cubic yards of contaminated sediment later, Lincoln Park is looking to reap the benefits of the newly cleaned Milwaukee River. As contractors work to remove equipment, sediment samples are being taken to ensure no contamination has been missed.
To commemorate this truly historic milestone, IISG environmental social scientist Caitie Nigrelli and I traveled to Milwaukee to spend some time on the river and celebrate the success with our clean-up partners. Hospitable as usual, Friends of Lincoln Park members took us around the city allowing us to catch a glimpse of the possibilities that environmental reinvestment holds for community revitalization.
Within the park, we took advantage of the warm fall weather for a canoe trip through the remediated portion of the river. As we paddled, perennial grasses and beaver-cut branches secluded us from Lincoln Park’s urban setting. We were not the only ones out experiencing the newly restored park; kill-deer, great blue herons, and other wildlife were also enjoying a clean habitat.
Although remediation work is complete, there is still much to be done within the park. Much like sediment remediation, successful ecosystem restoration is a long process. Started in 2012, the 11-acre Phase 1 restoration work is finally showing the fruits of its labor.
Many bees could be seen buzzing around native asters (see photo) and goldenrod on the shoreline at the west end of the park. Like Phase 1, restoration work in the East Oxbow of the river will bring a diversity of native plant species, stabilize the shoreline, and provide habitat for fish and wildlife.
After watching the sun set over the river, Caitie and I completed our day at the Friends of Lincoln Park restoration celebration. Over cake and ice cream, representatives from the Milwaukee County Parks and CH2M, an environmental consulting company, presented information on the remediation and restoration progress.
The neighborhood unity fostered through this river cleanup is impressive. As a new chapter begins for the river, park, and neighbors alike, seeds of passion and park investment are spreading, akin to the native seeds of restoration to come.
It was a chilly May 12th, cloudy and windy as well. But 29 sixth graders from West Side Middle School in East Chicago, Indiana came to nearby Roxana Marsh to experience what the outdoors has to offer, learn new things, help with the cleanup and restoration of the natural area, and enjoy the afternoon. Roxana Marsh is part of the larger Grand Calumet River Area of Concern, which has been undergoing dredging through the Great Lakes Legacy Act over the past six years. The marsh section of the project was completed three years ago with the removal of 600,000 cubic yards of sediment. This accomplishment was celebrated with a press event attended by government officials and local school children. Those middle schoolers left their legacy in perennial plants that are now thriving along the marsh. This year’s class is the third group of gardeners in what may well become an annual tradition.
In addition to planting natives, the students learned the basics of birding, explored the small community of life in sediment, and manned trash bags for garbage detail. There were water beetles, egrets, killdeer, toads, dragonfly nymphs, and more to experience.
Throughout their afternoon tour, the 6th graders were guided by experts from Audubon Chicago Region, U.S. EPA, The Nature Conservancy, Shirley Heinz Land Trust, Indiana’s departments of Natural Resources and Environmental Management, Northwest Indiana Regional Planning Commission, Dunes Learning Center, and Illinois-Indiana Sea Grant.
The first surprise for the students was just how close the natural area is to their school and their world. “They had no idea that this was here or about the dredging and restoration, said teacher Linda Padilla. “They were sure we would be going someplace farther away.”
Last June, she took part in a one-day workshop at Purdue University Calumet, which introduced the Helping Hands curriculum to 25 local educators. Helping Hands activities are ideally suited to schools in Areas of Concern that are going through the cleanup process—they provide opportunities to directly engage students in the larger project. The workshop also included a visit to several sites on the Grand Cal to see the dredging work in progress as well to walk around a finished site—Roxana Marsh.
Caitie McCoy, IISG environmental social scientist, has been helping keep residents informed during the dredging. She saw the Grand Cal project as an opportunity to connect students with their environment. “The cleanup and restoration of the Grand Calumet River is brightening the northwest Indiana landscape,” she explained. “This work transforms space into places that students can visit, perform stewardship work, and develop pride in their local environment. Environmental educators teach students that nature is in their backyard, but for these students, high quality nature is in their backyard, right here in East Chicago, Indiana.”
At one point, the Grand Cal was referred to as the most polluted river in the country. Through the remediation process, more than 2,000,000 cubic yards of sediment have been removed from this waterway, which runs through a highly-populated region. If funding from the Great Lakes Restoration Initiative continues and non-federal cost share partners are secured, the river work could finish as early as 2019.
A closer look at web tools and sites that boost research and empower Great Lakes communities to secure a healthy environment and economy.
Residents living near sediment remediation projects can now stay up-to-date on cleanup goals and milestones with GreatLakesMud.org. Developed by IISG, this comprehensive site provides information on waterways selected for cleanup and restoration through the Great Lakes Legacy Act.
At the heart of Great Lakes Mud are site-specific pages that identify contaminants of concern and outline plans for cleanup and habitat restoration. Here, visitors will find the latest on dredging schedules, truck routes, opportunities for community involvement, and more.
The website also provides insight into how Legacy Act projects are chosen and designed and explains how cleanup strategies like dredging and capping are able to remove the dangers of contaminated sediment while improving aquatic habitats.
Illustrative photos and videos bring these processes to life and help viewers understand how project components that often span several years fit together.
The Great Lakes Legacy Act was passed in 2002 to accelerate sediment cleanup in Areas of Concern, waterways blighted by decades of industrial discharges and poor municipal sewage practices. Since then, the program has cleaned up nearly 3 million cubic yards of contaminated sediment and restored acres of habitat.
For additional information or to request that your waterbody be added to the website, contact Caitie McCoy.
We talk a lot about the environmental benefits of sediment remediation. These are hard to miss—a trip to the river or harbor is often all it takes to confirm that the aquatic habitat is on the mend. The role of cleanup projects on local economies can be harder to pin down, but the impacts are just as striking. Brandon Steppan, IISG’s new communications intern, has the story.
I’ve lived in the city all my life. With the exception of a few parks and forest preserves, I never really saw environmental health as being all that connected to the welfare of my community. The only rivers that ever made the news were the Chicago River on St. Patrick’s Day and the Des Plaines River whenever it flooded—especially if that meant Gene and Jude’s, an iconic hot dog stand in River Grove and arguably the best place to get a Chicago-style hot dog, would have to shut down for repairs.
What I’ve learned about other Great Lakes communities in the short time I’ve been with IISG has already made me reevaluate just how valuable a healthy river can be—not just in terms of environmental integrity, but in dollars and cents. Results of economic studies of Great Lakes Areas of Concern (AOCs) have listed the values of what a clean waterbody would be for those communities, with numbers ranging from $6 million for one small neighborhood to $19 billion for all 31 original AOCs in the U.S. To get these numbers, economists and social scientists looked at money brought in from tourism, real estate values, and residents’ willingness to pay for a cleaner waterway.
One of the more remarkable returns came from a 2004 examination of the Waukegan Harbor AOC in Illinois. An analysis of housing data and resident perceptions determined that proximity to the PCB-ridden harbor substantially drove down property values. When surveyed, Waukegan homeowners revealed they would be willing to pay more for their property if it meant full cleanup of the harbor—a collective value of $436 million, much more than the projected cost for remediation.
My initial reaction to these reports was a mixture of confusion and surprise. But as I took into account the number of people in each area and how they rely on their local rivers not just for livelihood but for quality of life, the numbers no longer seemed all that surprising. The hazards of a toxic river bed aren’t always obvious, and unfortunately, neither are the benefits of remediation. Having these numbers available helps create a conversation where those benefits are no longer vaguely environmental, but economically tangible. ***Photo from the Waukegan Port District.
The Trenton Channel, part of the 32-mile Detroit River, could see a cleanup in 2016 through the Great Lakes Legacy Act, which combines federal funding with local support. Before that can happen though, voluntary partners must agree to help fund this final cleanup stage. The Detroit River is one of 29 remaining Areas of Concern in the U.S., a result of decades of poor environmental practices. The fast-moving Trenton Channel is one of the top sources of pollution in the river system due to its history of industrial and municipal practices. Scientists and engineers are currently designing a cleanup plan to address approximately 240,000 cubic yards of sediment in the upper portion of the Trenton Channel. A majority of the community surrounding this remediation project is looking with optimism and enthusiasm to the clean-up efforts. Yet these feelings are by no means unanimous.
Caitie McCoy, IISG social scientist, and her two summer interns—Mark Krupa and Erika Lower—conducted a needs assessment with local stakeholders of Trenton Channel, including environmentalists, recreation enthusiasts, property owners, and city officials. They found that the channel is viewed as important to the region, but that the clean-up plan is viewed with some skepticism.
Caitie explains:
I assumed that everyone would be overjoyed that a sediment remediation project was happening in their community. Yet there were quite a few concerns about the safety and effectiveness of the project. About a third of the stakeholders we interviewed said that cleaning up pollution would provide no significant community benefits.
This needs assessment has given our outreach team a better sense of what is important to our stakeholders. We have a better sense of what information they want about this project.
Increasingly, social science provides the go-to method for Sea Grant programs to develop informed outreach efforts. In the 2014-2015 research cycle, 29 programs funded 59 social science research projects. Additionally, state Sea Grant programs are hiring social scientists.
More from Caitie:
Large-scale needs assessments are a wise investment for big outreach projects. Needs assessments give us detailed information about our audience concerning a topic of interest–in this case, it was sediment remediation. This information would otherwise be difficult to obtain. Even working with an outreach team composed of local leaders, we make a lot of assumptions about our stakeholders. Needs assessments help us cut through those assumptions so that we can understand what our stakeholders are really interested in or concerned about. This helps us design better messaging and better outreach events for our stakeholders.
Exciting changes are coming to Wisconsin’s Lincoln Park, part of the Milwaukee River Area of Concern. Phase two of Great Lakes Legacy Act efforts to remove historical contaminants from the river bottom is set to begin next month. And park neighbors and stakeholders from across Milwaukee County are already well on their way to launching a Friends of Lincoln Park group that will help foster greater community stewardship.
More than 20 neighbors came together for the first time earlier this month to get to know each other, discuss potential group goals, and brainstorm ways to achieve them. They were joined by numerous local and regional organizations interested in protecting Lincoln Park, including University of Wisconsin Extension, Milwaukee County Parks, the Park People, and the Illinois-Indiana and Wisconsin Sea Grant programs.
Nothing is official yet, but the meeting ended with two main goals on everyone’s mind: fostering a sense of community with the park at the center and protecting the local environment.
“For a long time, the park was very community centered, but it has become more of an outsider attraction in the last few decades,” said Caitie McCoy, IISG’s social scientists and co-host of the meeting. “The group had great ideas for re-energizing community interest with events that bring locals out to enjoy all the resources the park has to offer.”
The idea for a Friends group took shape during focus groups conducted this spring by Caitie and UW-Extension’s Gail Epping-Overholt. They spoke with a variety of people living or working near Lincoln Park to better understand community perceptions of the park and ongoing sediment remediation efforts. When the results of the needs assessment were in, it was clear that residents were interested in forming the Friends of Lincoln Park.
The results will also play a key role in shaping public outreach and project messaging as dredging kicks off again this fall for phase two of the remediation. More than 120,000 cubic yards of contaminated sediment have already been removed from the Lincoln Park segments of the Milwaukee River, and this next round of dredging is expected to remove another 35,000 cubic yards. Together with cleanup efforts in nearby Blatz Pavilion lagoon, the two Lincoln Park projects are expected to reduce the amount toxic PCBs flowing into the Milwaukee River system by 70 percent, a drop that will go a long way towards delisting the AOC.
To learn more about recommendations to come out of the needs assessment, download the full report from our products page. And if you live in the area and are interested in joining the Friends of Lincoln Park, come out to the next meeting on October 9.
Special thanks to IISG interns Erika Lower and Mark Krupa for their help analyzing and the results of the needs assessment and to Jane Harrison at Wisconsin Sea Grant for taking notes during the focus groups and helping to coordinate the Friends meetings. ***Photo courtesy of University of Wisconsin-Extension.
