Sediment Management Standards (SMS), Chapter 173-204 WAC. Of the 2063 SEDQUAL samples from central Puget Sound, 1034 have chemical contaminant levels that exceeded at least one SQS or CSL value. The majority of these stations are located near population centers, urban and industrial areas, and ports, including Elliott Bay and the Duwamish River, Sinclair Inlet, Dyes Inlet, Liberty Bay, and Eagle Harbor (Figure 2). A summary of the chen~icals found in these central Puget Sound SEDQUAL samples which exceeded SMS values, including their sample location and total number of samples, is given in Appendix A. In central Puget Sound, all 47 chemicals with SMS values were exceeded on at least one occasion. Goals and Objectives The shared goal of this study for both the PSAMP Sediment Monitoring Component and NOAA's nationwide bioeffects assessment program was to characterize the ecotoxicological condition of sediments, as well as benthic infaunal assemblage structure, as a measure of adverse biological effects of toxic chemicals in central Puget Sound. Based upon chemical analyses of sediments reported in previous studies, it appeared that there were relatively high probabilities that concentrations were sufficiently high in some regions of the study area to cause acute toxicity and infaunal assemblage alterations. Data from toxicity tests were intended to provide a means of determining whether toxic conditions, associated with high concentrations of chemical pollutants, actually occurred throughout any of the area. Examination of infaunal assemblages was intended to determine whether sediment chemistry and toxicity conditions are correlated with patterns in infaunal community structure. Underlying these goals was the intent to use a stratified-random sampling design that would allow the quantification of the spatial extent of degraded sediment quality. Based on the nature of sediment contamination issues in Puget Sound, and the respective mandates of NOAA and the state of Washington to address sediment contamination and associated effects in coastal waters, the objectives of the cooperative assessment of bioeffects in Puget Sound were to: 1 Determine the incidence and severity of sediment toxicity; 2. Identify spatial patterns and gradients in sediment toxicity and chemical concentrations; 3. Estimate the spatial extent of toxicity and chemical contamination in surficial sediments as percentages of the total survey area; 4. Describe the composition, abundance and diversity of benthic infaunal assemblages at each sampling location; 5. Estimate the apparent relationships between measures of sediment toxicity, toxicant concentrations, and benthic infaunal assemblage indices; and 6. Compare the quality of sediment from northern, central, and southern Puget Sound measured in the three phases of this study. Page 6
This report includes a summary of the data collected in 1998 and correlation analyses to examine toxicity, chemistry, and infaunal relationships. Results of further analyses relating toxicity, chemistry, and infaunal structure throughout the entire survey area will be reported in a subsequent document. Page 7
