Ecological evaluation of proposed dredged material from Bulls Head Channel (lower Suisun Bay)
- Battelle/Marine Sciences Lab., Sequim, WA (United States)
This report describes the sampling and testing program conducted for USACE by Battelle/Marine Sciences Laboratory (MSL) to address (1) exclusion from further testing for ocean disposal, (2) suitability of open-water disposal within San Francisco Bay, and (3) beneficial uses, based on open-water and upland (leaching) disposal criteria, for the estimated 1.86 million cubic yards of sediment to be dredged from Bulls Head Channel and turning basin. To meet these objectives, core samples were collected from 28 locations to a depth of -47 ft mean lower low water (MLLW), which is -45 ft MLLW plus 2 ft overdepth. One to three samples per coring location were characterized physically and chemically; sediment from groups of locations and from various depth strata were combined into composite samples for biological toxicity characterization in addition to physical and chemical characterization. The chemical and biological tests were conducted following the guidance of USACE, the US Environmental Protection Agency (EPA), and state regulatory agencies.
