| Abstract | Long Description |
Sediment from twelve stations in Ostrich Bay will be evaluated for compliance with the Washington State Sediment Management Standards. Four bioassays will be used to test the sediments for toxicity: amphipod, marine larva, juvenile polychaete (Neanthes) and Microtox®. Previous testing in 1994 and 1997 showed widespread toxicity in the bay and a former Naval ammunition depot is known to have polluted it with munitions chemicals, metals, and other chemicals during operations from 1904 to 1959. Sediment to be collected for toxicity testing will also be analyzed for chemical pollutants. These include mercury and other priority pollutant metals, semivolatile organic compounds, and munitions chemicals (nitroaromatics, nitramines, and perchlorate). Testing will also be conducted for sulfides, which can have a natural or anthropogenic origin and can contribute to sediment toxicity. Results from this study will be used by the Department of Ecology Toxic Cleanup Program′s Sediment Management Unit to assist in making sediment cleanup decisions for Ostrich Bay. |
