Richland, California is an important commercial port in San Francisco Bay. The San Francisco District of the US Army Corps of Engineers (USACE) plans to increase the depth of Richmond Harbor and Santa Fe Channels to -38 feet Mean Lower Low Water (MLLW) to accommodate deep-draft commercial vessels. The total volume of dredged material is expected to be approximately 1.4 million cubic yards. The options for disposal of the dredged material are aquatic disposal and upland disposal. The purpose of this study was to develop a database on chemical compounds in the dredged material to assist with determination of disposal methods and the need for additional testing. This purpose was accomplished through an extensive field sampling program followed by chemical analysis of samples. Field sampling involved collection of core samples from Sante Fe and Richmond Harbor Channels. Cores were shipped to Battelle/Marine Sciences Laboratory, where they were subsampled for chemical analysis and/or archived by freezing. All sediment and water samples were analyzed for priority pollutants, including metals, organotins, base/neutral semivolatile organic compounds, chlorinated pesticides and PCBs, herbicide acids, and acidic phenols. Sediment samples were also analyzed for oil and grease and total organic carbon. Organophosphorus pesticides and dioxins and furans were measured in selected sediment samples from Richland Harbor Channel and from both sediment and water samples from Santa Fe Channel. 21 refs., 10 figs., 60 tabs.
