Infaunal Patterns in the Vicinity of a Small Coastal Wastewater Outfall and the Lack of Infaunal Community Response to Secondary Treatment
In July 1985 the Encina Wastewater Authority began discharging ad- vanced primary treated wastewater into Southern California coastal waters at a depth of 45 meters. This discharge was upgraded to full secondary treatment in October 1988, which resulted in substantial improvements in effluent quality. An eight year monitoring program has recorded the response of the infaunal com- munity to the wastewater discharge and changes in treatment. Except for lower abundance of Amphiodia urtica near the outfall, the wastewater discharge appears to be beneficial to the infaunal community by enhancing diversity. There were no indications of temporal changes related to improved treatment levels.
