In the news: Grand Calumet AOC project, harbor dredging resume

Harbor dredging in Indiana, part of the cleanup efforts in the Grand Calumet Area of Concern, is set to resume next month. 

"Since 2012, the project has dredged roughly 400,000 cubic yards of sediment out of an estimated backlog of 1.6 million cubic yards and stored it in a confined disposal facility. Prior to 2012, dredging hadn’t occurred in 40 years because the U.S. Environmental Protection Agency determined that the previous open-water disposal method was unacceptable.

The canal is part of the EPA’s Grand Calumet River Area of Concern because of its historical contamination by polychlorinated biphenyls (PCBs), polycylclic aromatic hydrocarbons (PAHs) and heavy metals.

Aaron Harke, a project manager with the Durocher Marine division of Kokosing, said the dredging start date depends on ice conditions on Lake Michigan. A boat that is used in the project is moored in Chicago with no way to get it to East Chicago, he said."
