| Description | Ecology conducted a Class II Inspection of Port Orchard Wastewater Treatment Plant on January 17 19, 1989. Effluent quality was good. The plant met all NPDES permit requirements at the time of inspection. Several volatile organic contaminants were found in the influent and in the sludge. Bioassays using trout, Microtox, and Rhepoxynius abronius did not indicate an effluent or sediment toxicity. Fifty percent mortality of Daphnia magna in 100 percent effluent was observed; however, the low hardness of the sample may have caused the observed effect. The mercury concentration was slightly elevated in the At Outfall sediment. Port Orchard lab techniques and results were acceptable. | ||||
