The report describes the results of a field survey south of the Tacoma Narrows bridge in southern Puget Sound. Environmental conditions were evaluated in two urban embayments, eight nonurban embayments and three areas of the main channel in the southern Sound. Stations were located in depositional areas where chemical contaminants would be expected to accumulate in the sediments. All stations were located away from known contaminant sources in order to provide integrative assessments of contamination over relatively large areas. Chemical contamination of the south Sound was evaluated by measuring chemical concentrations in subtidal bottom sediments. Bioaccumulation of chemical contaminants was evaluated by measuring chemical concentrations in flatfish muscle tissues and littleneck clam meats. Chemical-related biological effects were evaluated by conducting amphipod sediment bioassays and histopathological analyses on livers of English sole.
