Cleanup a huge step in river restoration effort

A $52 million sediment cleanup in Indiana’s Grand Calumet River has put one of America’s most polluted rivers on the road to recovery.

The Grand Calumet River

The Grand Calumet River and the Indiana Harbor and Ship Canal, near Chicago, comprise one of the most industrialized waterways in the United States. The river and harbor discharged 150,000 cubic yards of contaminated sediment into Lake Michigan annually before cleanup efforts began last year.

Crews have dredged 232,000 cubic yards of toxic sediment from the west branch of the Grand Calumet and the 19-acre Roxana Marsh. The cleanup of the entire river is far from complete, but the Grand Calumet has turned a corner after decades of abuse.
