Toxic chemicals, such as PAHs, sorb to sediment rather than dissolve in water. Therefore, traditional water-quality (WQ) monitoring analysis of water samples likely underestimates total chemical concentrations to which Chinook salmon and other aquatic species are exposed. The USGS developed a new field centrifugation method to quantify suspended sediment-bound chemical concentrations and fluxes. We will follow the model of work established at the Duwamish River, including continuous river flow and turbidity, discrete measurements of WQ, suspended sediment concentration and particle-size distribution, and centrifugation for suspende...
