Dredging Operations Technical Support Program: Evaluation of Hopper Loading and Overflow for Saginaw River, Michigan
The US Army Engineer District, Detroit, maintains a navigation channel in the Saginaw River near Saginaw, MI. The sediments in some reaches contain metals and polychlorinated biphenyls (PCHBs). A hopper dredge is normally used, and overflow of the hopper is sometimes practiced to increase the load of solids for transport to the disposal area. The Detroit District has initiated a policy of no overflow in reaches of the channel where sediment PCB concentrations exceed 10 mg/kg (dry weight). However, there is concern over the possible impact of overflow from hopper dredging operations when sediments are dredged from other reaches of the channel where sediment PCB concentrations are less than 10 mg/kg. This report describes an evaluation of hopper loading and overflow characteristics of the Saginaw River conducted during August and September 1987. The study was designed to evaluate the effectiveness of increasing the hopper load during overflow and to determine the physical and chemical characteristics of the overflow for the Saginaw project. Keywords: Contaminated sediments, Dredging equipment, Overflow, Polychlorinated biphenyls, Water quality. (sdw)
