Major sources of contamination to Puget Sound are concentrated in the urban embayments. Most of these contaminants are particulates or adhere to particles. If these particulates are dense, they tend to fall out of the water column near the source; thus analysis of the sediment within urban embayments can provide an indication of the level of contamination, and by proximity, of the probable source of that contamination. During spring and summer 1985, and again in January 1986, the Pacific Marine Environmental Laboratory (PMEL) of the National Oceanic and Atmospheric Administration (NOAA) made a series of observations designed to determine to what degree contaminants in Elliott and Commencement Bays could leave the bays and enter the main basin of Puget Sound. The approach employed in the study was to map the distribution of water properties (salinity, suspended particulate matter or SPM, and toxic trace metals and organics) during a period of high river runoff and during combined sewer overflow events after heavy rainfall. Current meters and sediment traps were employed, providing a continuous record of salinity, temperature, current speed and direction which allows a calculation of horizontal transport.
