Abstract: An extensive study on the effect of dispersion, settling, and resedimentation on the migration of chemical constituents during open-water disposal of dredged material shows that concerns regarding the release of any significant quantity of toxic materials into solution phase are unfounded. However, the study indicates that trace metals and chlorinated hydrocarbons associated with macro-molecular organics and suspended particles released to the water column as a result of dredging may have some unknown effect. For example, the availability of these organic compounds as a food source for filter-feeders and algae may present some potential problems. Water and sediment samples collected from marine and freshwater environments and subjected to laboratory experiments simulating the impact of open-water disposal on water quality provided data to quantify the migration of trace contaminants and nutrients under various conditions during resuspension and resettling. Also presented are the results of an investigation of the chemistry of chlorinated hydrocarbons and organo-metallic complexes as related to their bioavailability.
