Because of the animal hides and hairs in the sediments, there could be odors from the sediment, although keeping them wet will keep the odors down. Trucks would transport the sediments for final disposal, most likely to a landfill that is licensed to take residential solid waste. After the sediments are completely removed and trucked to a disposal facility, the sheet pile wall would be removed and the bottom of the bay leveled off if necessary. Dry dredging is one method that can minimize the distribution of contamination to other parts of the lake. In a wet dredging process, the contaminated sediments would be removed by either a hydraulic dredge or an environmental clamshell or bucket.
Hydraulic dredges work like vacuum cleaners to remove bottom sediments and associated water.
Using either the hydraulic dredge or the environmental clamshell, the sediment and water mix is transported to a dewatering facility on shore where the sediments and water are separated. The sediments are then stored as in the dry dredging method until transported to a disposal facility. The water is tested and treated if necessary before being returned to White Lake. Because the water mixes with the sediments during the removal process, it is more likely to be contaminated than in the dry dredging process. In a wet dredging process, plastic silt curtains are installed around the perimeter of the area to be dredged to stop contamination from dispersing throughout the lake.
