The gloves are off and the shovels are in at the Trowbridge Dam, as the U.S. Environmental Protection Agency has begun its concerted crack at cleaning up the PCB-tainted muds and banks of the Kalamazoo River. We’re talking a 2.4-mile stretch of environmental rehabilitation upstream of the dam, which, if you weren’t aware, is part of the rather ominously named Allied Paper Inc./Portage Creek/Kalamazoo River Superfund site. The cleanup works signaled the starting pistol for a much-needed teardown in the area, as reported by WZZM13.
