Ostrich Bay Sediment Toxicity Evaluation (Number of pages: 75) (Publication Size: 1MB)

| Description | Sediment in Ostrich Bay, near Bremerton, Washington, was tested for toxicity using four bioassay tests in accordance with the Washington State Sediment Management Standards. The sediment samples were also chemically analyzed. A former Naval ammunition depot discharged metals and other chemicals into the bay during operations from 1904 to 1959. Biological regulatory criteria for sediment quality were exceeded at six of the 12 sampling stations, based on the bioassay testing. The Sediment Quality Standard for mercury was also exceeded at six stations. The basis for the observed sediment toxicity is unknown. Elevated sulfide levels in Ostrich Bay do not appear to be a contributor. A previous attempt to identify a metal or organic contaminant responsible for the toxicity of Ostrich Bay sediments also was unsuccessful. |
