Elliott Bay Action Program: The relationship between source control and recovery of contaminated sediments in two problem areas. Puget Sound Estuary Program. Final report

OSTI ID:6872296
Results are presented from a study to evaluate the relationship between source control and mitigation of sediment contamination in two high-priority problem areas in Elliott Bay, Seattle. The time necessary for sediment concentrations to be reduced to target cleanup levels after complete source elimination is estimated for each problem area through application of the Sediment Contamination Assessment Model (SEDCAM), using a mass-balance equation, developed for Commencement Bay. The important variables include: concentration of problem chemicals in recently deposited material and surface sediments; sedimentation rates, mixed layer depth and the rate at which problem chemicals are lost due to biodegradation and diffusion across the sediment-water interface. In addition, the model predicts the fraction of source control required to maintain sediment concentrations at the target cleanup levels for each problem area.
