| Abstract | Long Description |
A pilot eight-day coho salmon smolt bioassay was performed on selected wastewater discharges to Grays Harbor to help identify the cause(s) of low out-migrant survival. Ecology participated in the project by analyzing the tested effluents and dilution water. Ten percent solutions of two pulp mill effluents and a municipal sewage effluent were collected at day one and again at day four when the solutions were renewed. All samples were analyzed for conventional, metal, volatile organic, semi-volatiles, resin acid, and guaiacol constituents. Analytical results indicated the effluents contained concentrations similar to those quantified in other studies. Recommendations for improvements in the bioassay procedure and analytical methods were made in anticipation of a full-scale bioassay. |
