Contaminated marine sediments exist in many US waterways. Dredging is often a convenient and economical method of safely removing these sediments. However, significant concern exists over the potential environmental effects resulting from the localized sediment resuspension and contaminant release that may occur during the removal operation. This report synopsizes hydraulic equipment, pneumatic equipment, and mechanical components used for dredging and innovative modifications to their dredgeheads. It also examines previously tested dredging equipment designed to remove fine-grained sediments with a minimum amount of sediment resuspension. Major features of equipment innovations, along with available field testing information, are discussed. From these findings, the most promising innovations and research needs are identified. Since this report focuses on the dredging operations, only dredge sizes and sediment resuspension quantities are reported.
