Abstract

Department biologists, under contract for the State Water Resources Control Board, conducted a survey of the marine environment in the vicinity of two oil field brine discharges at Huntington Beach. Survey procedures included benthic grabs, diver observations, bottom trawls and measurements of water temperature and dissolved oxygen concentrations. A stratified random sampling plan was used to locate the 12 station areas surveyed. Water depth ranged from 9 to 15 m (30 to 50 ft). The results of this survey do not indicate that the discharges are having an effect on the benthic populations sampled. It is concluded that the scope of the survey was not sufficient to conclusively evaluate the effects of the two discharges. Recommendations are made for additional surveys to include intensive sampling of populations at the discharge depth and shoreward over an extended period of time, rather than a survey of the type conducted over a single period of time.
