Book Description
The report presents sampling data on the infauna organisms in the Bay. Eleven stations were established in three project sites and four disposal areas. Five sampling periods over a period of one year were used to represent conditions ranging from high fresh water inflow in the winter to the dry period in late summer. In addition to the taxonomy, sediment analysis included temperature, pH, total sulfides, grain-size distribution and heavy metals - Cu, Cd, Zn, Pb and Hg. Water sample analysis included temperature, salinity, dissolved oxygen, pH, total sulfides and optical turbidity.

Book Description
The objective of this study has been to ascertain the effects of dredging and disposal operations on the water quality of San Francisco Bay with particular emphasis on the degree and duration of associated sediment resuspension. To achieve this objective water quality monitoring was performed in several areas of the Bay influenced by dredging and disposal operations during 1972-1975. The purpose was to record and quantify deviations from background of suspended solids loading, light transmission, dissolved oxygen content, temperature, salinity/conductivity and pH of the water column.

Book Description
In April 1972, the San Francisco District of the United States Army Corps or Engineers initiated a study to quantify the impact of dredging and dredged sediment disposal operations on the environment of San Francisco Bay and Estuary. The study has generated factual data, based on field and laboratory studies, needed for the Federal, State and local regulatory agencies to evaluate present dredging policies and alternative disposal methods. The study was set up to isolate the questions regarding the environmental impact of dredging operations and to provide answers at the earliest date. The study was organized to investigate (a) the factors associated with dredging and the present system of aquatic disposal in the Bay, (b) the condition of the pollutants (biogeochemical), (c) alternative disposal methods, and (d) dredging technology. The study elements were intended first, to identify the problems associated with dredging and disposal operations and, second, to address the identified problems in terms of mitigation and/or enhancement. The division into separate but inter-related study elements provided a greater degree of expertise and flexibility in the Study. Since the publication of the Main Report in February 1977, several miscellaneous studies dealing with dredging were conducted in the Bay. Although the studies were not part of the Dredge Disposal Study, they have been gathered together to form this appendix in order to make the basic data available. (Author).
