Techniques for reducing turbidity associated with present dredging procedures and operations fall principally in the categories of the cutter, ladder, suction, hull, pipeline, connections, barges, tenders, personnel, inspection, contracts, plans, and specifications. These techniques consist principally of good dredging procedures already known but not always followed by dredging contractors and their personnel. When these techniques are consistently applied, not only will dredge-induced turbidity be reduced, but economical operation will prevail in most instances. Other techniques for reducing dredge-induced turbidity tend to increase dredging costs and should be used only when necessary. Dredge-induced turbidity is normally apparent only in the immediate vicinity of the dredge plant and the levels of this turbidity are not usually as high as those created by open-water disposal of the dredged material. In addition to applying good dredging techniques to reduce turbidity, better inspection is needed on Corps of Engineers (CE) and CE-related projects. More CE supervision of dredging operations needs to be implemented. More training is required for inspectors, whether CE or private-company personnel. Consideration should be given to a nationwide school or short courses where dredge personnel could obtain basic technical knowledge of dredging. Contracts should clearly and uniformly specify requirements for turbidity-reduction measures and measurements. Contracts should be written to include smaller dredges. Where turbidity is a problem, dredging should be accomplished when natural background levels of turbidity are high. /Author/
