Title: Chemical evaluations of John F. Baldwin Ship Channel sediment

Abstract

In October 1989, the Battelle/Marine Sciences Laboratory (MSL) conducted sampling, geological characterization, and chemical evaluation studies on sediment from a proposed ship channel in San Francisco Bay, California. This channel extends from the San Francisco Bar, through San Pablo Bay, into Carquinez Strait, and on to Sacramento. The 1989 study area included a 28-mile-long portion of the John F. Baldwin Ship Channel that extended from West Richmond to and including Carquinez Strait. The objective of our study was to determine physical characteristics and chemical contaminant levels in sediment to the proposed project depth of {minus}45 ft mean lower low water (MLLW) (plus 2 ft of overdepth). Sediment core samples were collected at 47 locations throughout the John F. Baldwin Ship Channel using a vibratory hammer core sampler. Ten of these locations were from West Richmond, 29 from San Pablo Bay, and 8 from Carquinez Strait. The geological properties of sediment core samples were described, the sediment from the cores was composited into 72 separate samples based on those descriptions, and chemical analyses were conducted of 13 metals, 16 polynuclear aromatic hydrocarbons (PAH), 18 pesticides, 7 PCBs, 3 butyltins, and 4 conventional sediment chaacteristics. These data were then compared with sedimentmore » values from Oakland and Richmond harbors, reference values from Point Reyes fine- and coarse-grained sediments, and from typical shale sediment. 22 refs., 23 figs., 10 tabs.« less

    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. Butyltinmore » 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.« less

    To assist the US Army Corps of Engineers (USACE) in determing whether the material from proposed dredging of the John F. Baldwin Ship Channel (JFBSC) is suitable for unrestricted, unconfined open-ocean disposal, Battelle/Marine Sciences Laboratory (MSL) prepared this report. Based on these findings, sediments that would be removed during Phase III improvements to the JFBSC fail to meet the three suitability criteria for open-ocean disposal. Firstly, fine-grained sediments comprise a significant fraction of the bottom material in some areas of the channel, and this material is not exposed to high current or wave energy. Dredged material from the JFBSC ismore » not being proposed for beach nourishment; therefore the second criterion is not met. JFBSC sediments do not meet the third criterion because, although they may be substantially similar to substrates at several of the proposed disposal sites, they are from an area that historically has experienced loading of contaminants, which toxicology studies have shown have the potential to result in acute toxicity or significant bioaccumulation.« less

    The John F. Baldwin Ship Channel is a 28-mile-long portion of the San Francisco Bay to Stockton Ship Channel, the primary shipping lane through San Francisco Bay and Delta. The San Francisco District of the US Army Corps of Engineers (USACE) is responsible for construction of the John F. Baldwin Ship Channel, which is authorized to be deepened to a project depth of {minus}45 ft relative to mean lower low water (MLLW). Approximately 8.5 million cubic yards (mcy) of sediment will be removed from the channel to reach this project depth. The USACE requested Battelle/Marine Sciences Laboratory (MSL) to conductmore » testing for ocean disposal under the guidelines in Evaluation of Dredged Material Proposed for Ocean Disposal-Testing Manual (EPA/USACE 1991). This testing manual contains a tiered evaluation approach developed specifically for ocean disposal of dredged material at a selected site. In this study, John F. Baldwin Ship Channel sediments were evaluated under the Tier III (biological) testing guidance, which is considered to be highly stringent and protective of the environment. The Tier III guidance for ocean disposal testing requires tests of water column effects, (following dredged material disposal), deposited sediment toxicity, and bioaccumulation of contaminants from deposited sediment (dredged material).« less

  • This report presents the development of a CHaNnel TRaNsport model for simulating sediment and chemical distribution in a stream/river network. A particular feature of the model is its capability to deal with the network system that may consist of any number of joined and branched streams/rivers of comparable size. The model employs a numerical method - an integrated compartment method (ICM) - which greatly facilitates the setup of the matrix equation for the discrete field approximating the corresponding continuous field. Most of the possible boundary conditions that may be anticipated in real-world problems are considered. These include junctions, prescribed concentration,more » prescribed dispersive flux, and prescribed total flux. The model is applied to two case studies: (1) a single river and (2) a five-segment river in a watershed. Results indicate that the model can realistically simulate the behavior of the sediment and chemical variations in a stream/river network. 11 references, 10 figures, 3 tables.« less

  • In 1980, vegetative stress and arboreal mortality in wetland plant communities down-gradient from the F- and H-Area seepage basins were detected using aerial imagery. By 1988, approximately six acres in H-Area and four acres in F-Area had been adversely impacted. Today, wetland plant communities have become well established at the H-Area tree-kill zone.
