Abstract:

Long-term trends in the physical, chemical, and biological characteristics of dredged material at a deepwater, experimental disposal site in Elliott Bay, Seattle, Washington, were studied. This site was studied previously as part of the US Army Corps of Engineers Dredged Material Research Program which determined the behavior of dredged material during disposal and characterized its impact over the following 9 months. The site was selected for additional work for a number of reasons. The dredged sediments contained high concentrations of polychlorinated biphenyls PCBs and the benthic community did not recover to predisposal conditions during the original study. Results of this study provide a basis for a realistic evaluation of the environmental impacts of open-water dredged material disposal and thus assist in establishing environmentally sound management strategies for future disposal activities.
