PCBs have posed such problems for the Kalamazoo River that summits have been held to figure out how to deal with aging dams that threaten to unleash more PCB-laden sediments into the watershed. The chemicals arrived on the scene when paper mills started dumping their inks into the water. Due to the Superfund a lot of the sediments have been cleaned and nearby underground toxic dumps have been temporarily reinforced to keep the groundwater safe. And while this great effort has resulted in a reduction in PCB’s over the years, there still exists some trapped in-between aging dams that need to be addressed before the river can truly be restored.
