Elliott Bay Action Program: Analysis of Toxic Problem Areas. Puget Sound Estuary Program. Final Report and Appendices. Two Volumes

摘要

The report presents the results of a field investigation of the nearshore region of the Elliot Bay/Duwamish River system, in Seattle. Under the Elliott Bay Urban Action Program, federal, state, and local agencies cooperate to respond to toxic contamination problems. Response actions may include regulatory control of point and non-point contamination sources, source treatment, capping or removal of highly contaminated sediments. The study objectives were to: (1) define spatial patterns and quantitative relationships between sediment contamination, toxicity and biological effects; (2) identify problem areas of sediment contamination; (3) rank problem areas for possible remediation; (4) identify potential problem chemicals that display high concentrations in association with biological effects. A standardized assessment technique used in several other Puget Sound Estuary Program urban bay projects was used to identify problem sediments.
