The diversity of disposal alternatives and techniques for management of contaminated dredged material requires the development of an overall long-term management strategy for disposal. The selection of an appropriate strategy is dependent on nature of the dredged material, nature and level of contamination, available dredging alternatives, project size, and site-specific physical and chemical conditions, all of which influence the potential for environmental impacts. Technical feasibility, ecomonics, and other socioeconomic factors must also be considered in the decisionmaking process. The management strategy presented mainly considers the nature and degree of contamination, potential environmental impacts, and related technical factors. The technical strategy is based on findings of research conducted by the US Army Corps of Engineers, the US Environmental Protection Agency, and other over the past 10 years and experience gained while actively managing dredged material disposal. Approaches for evaluating potential for contaminant-related problems and the applicability of various disposal alternatives are discussed. Detailed procedures for conducting tests or for design and implementation of management strategies are not presented, but are the topics of other papers to follow. A technically feasible and environmentally sound strategy for the disposal of dredged material is presented, and it is recommended that this strategy be implemented for future dredged material disposal operations.
