Maintenance of navigation in the Nations waterways requires the annual dredging of more than 400 million cubic yards of estuarine, lacustrine, and riverine sediments. As part of the Corps of Engineers comprehensive Dredged Material Research Program, various avenues are being explored for productive uses of dredged material, with or without mechanical or chemical treatment. Several studies have been initiated seeking ways to use the fine-grained, low-density, high-water-content, nutrient-rich characteristics as assets rather than liabilities. These include using the material for strip mine reclamation, filling abandoned pits or quarries, cover for sanitary landfills, and agricultural land enhancement. Initial investigations are concentrating on aspects relevant to any related use, i.e., relatively long distance transport systems including collection and distribution subsystems involving pipeline, rail, barge, and other modes and geochemical and geohydrological considerations of leachate and groundwater contamination potential.
