To assess the potential impact of contamination by ordnance compounds and their contribution to environmental degradation in two areas of Puget Sound, Washington, an extensive study was undertaken. It included the generation of a toxicity database of ordnance compounds to marine organisms, and sediment toxicity and chemical analyses of 50 stations in the vicinity of the Jackson Park and Port Hadlock naval facilities, Puget Sound, including Toxicity Identification Evaluation TIE studies at selected stations. Eight ordnance compounds of concern were selected and analyzed for toxicity with six different kinds of marine toxicity tests, which included five species and phyla, and nine endpoints. Toxicity tests and endpoints were fertilization success and embryological development with the sea urchin Arbacia punctulata zoospore germination, germling length and cell number with the green macro-alga Ulva fasciata survival and reproductive success of the polychaete Dinophilus gyrociliatus larvae survival with the redfish Sciaenops ocellatus and survival of juveniles of the opossum shrimp Mysidopsis bahia. The overall toxicity, chemistry, and TIE test results indicate that ordnance compounds are not contaminants of concern at any of the sites studied in Puget Sound, Washington.
