Abstract:

An intensive series of investigations were conducted on the sediments deposited in Craney Island, a 1012 hectare contained disposal facility in the Port of Hampton Roads, VA. Geographic and geological mappings of the Facility were made in conjunction with toxicity bioassays and chemical investigations of organics and inorganics found in the dredged sediments. Although higher body burdens of most metals in the test species were associated with the coarsest sediments, there was relatively low toxicity from these contaminants. The vast majority of the sediments tested appeared to meet the criteria for open ocean disposal.
