The 80-mile PCB cleanup started in 1998. That is, the cleanup has been ongoing during the 21st Century. "The Kalamazoo is polluted with polychlorinated biphenyls, or PCBs, from paper recycling mills. Used for ink removal, the chemicals were discharged into the river from the 1950s through the mid-1970s. They also seeped into groundwater and surface waters from landfills where mill waste was dumped." "The agreement represents a significant milestone in the overall cleanup, which is expected to end up costing about $851 million, Clark said. Payment negotiations are continuing with other companies that share responsibility for the pollution, including Georgia-Pacific, International Paper and Weyerhaeuser." |

The bags are full of the contaminated material dredged from the river — the goal is to keep the contaminated sediment in the bags and remove the water for treatment. Surface tension inside the bags can cause sediment to plug holes and stop water from flowing out. Workers break the tension by using power washers, large machines and even whips, laboring long hours in the sun while wearing full protective equipment." |
