A total of $13.5 million has been appropriated to remove sediments contaminated by PCBs, mercury, DDT and other toxins from the Detroit River, Pine River, Muskegon Lake, White Lake, Wolf Creek, Deer Lake, River Raisin, Rouge River and Deer Lake. The value of relocating pollutants from river bottoms to another location is debatable when potential exists for exacerbating water contamination levels by "stirring" toxins during removal. But reducing toxic concentrations in waterways is potentially beneficial.
