Chemical evaluations of John F. Baldwin Ship Channel sediment phase 2
In August of 1990, the battelle/Marine Sciences Laboratory (MSL) conducted a program of sampling, geologic characterization, and chemical analysis of sediments from five sites in the West Richmond reach of the John F. Baldwin Ship Channel in San Francisco Bay. Additional sediment samples were collected for the USACE Waterways Experiment Station (WES) Wetlands and Uplands testing programs. The objective of the MSL study of the five West Richmond sites was to determine the physical characteristics and chemical contaminant levels in sediments proposed for dredging. Metals concentrations were comparable to or lower than those reported in the Phase 1 study. Butyltin concentrations were very low, and organic contaminants (PAH, PCB and pesticides) were not detected. Differences between Phase 1 and Phase 2 results may be explained by the fact that Phase 2 stations are outside the shipping channel. 16 refs., 4 figs., 16 tabs.
