Disposal of digested sewage sludge in coastal marine waters off Southern California is technically feasible, although it is not permissible under present policies of the state and federal governments. A one-dimensional model of physical and chemical processes in the San Pedro-Santa Monica Basin was developed to project environmental responses to different disposal strategies. The model suggests that deep disposal (800 m) would have crucial impacts on oxygen concentrations but shallower disposal (400 m) would not. Trace metal and sulfide buildup should not be significant problems. Organic particle buildup poses unknown problems for deep-living fauna.
