At the request of the US Army Corps of Engineering (USACE), environmental studies were conducted by Battelle/Marine Sciences Laboratory (MSL) to evaluate the suitability of sediments from Oakland Inner Harbor for dredging and ocean disposal. During the Phase 3 38-Foot Project, sediment cores were collected from mudline to {minus}39 ft mean lower low water at various locations in Oakland Inner Harbor channel and allocated to six composite samples. These composites were evaluated through physical/chemical analyses, acute toxicity to sensitive marine organisms, and bioaccumulation potential. Sediment samples from individual locations were tested for physical/chemical parameters only. The results of toxicological and bioaccumulation testing may be used by USACE to determine the amount of potential dredged material from Oakland Inner Harbor channel acceptable for open-water disposal as defined by the Draft Implementation Manual (EPA/USACE 1990) and consistent with the Water Resources Development Act of 1986 (Public Law 99-662). This is Volume 1 of a two-volume data report that presents the data gathered during the Oakland Harbor Phase 3 38-Foot Project, conducted in the Fall of 1990. This data report does not include interpretation or statistical analysis of the 38-Foot data. Volume 1 includes the project background as well as a full presentation of data and results in Appendixes A through H. Volume 2 contains the remaining data in Appendixes I through L.
