Abstract:

Heightened environmental awareness beginning in the 1970s focused upon lowering contaminant levels in the Kalamazoo River system through the improvement of water quality. The Michigan Department of Natural Resources (MDNR), Surface Water Quality Division began working toward the improvement of water quality and restoration of the river as a recreational resource. High contaminant levels persist in fish populations and result from the storage of PCB contaminated deposits in the floodplain. Contaminated deposits constitute a unit of variable thickness within the valley margins. The identification of the uneven distribution and thickness of stored PCB sludges through the application of geomorphic principles is an approach being used by the MDNR to incorporate a focused remedial action program.
