The Orange County Environmental Management Agency water quality monitoring program in Newport Bay and its watershed is reported. The objectives of this program are to establish a sound baseline of data for future management decisions on the operation, protection and restoration of the Newport Bay ecosystem; to detect sources of various pollutants; and to determine solutions to water quality problems and issues. General physical parameters, nutrient and trace elements are monitored on a regular monthly basis while other parameters such as pesticides, polychlorinated biphenyls, phenolic compounds, oil and grease, methylene-blue-active substances, and trace elements in sediments are monitored on a semi-annual basis. The study period for this report is 1973 to 1979 for watershed water quality monitoring and 1976 to 1979 for Newport Bay water quality monitoring. The results of these analyses are presented in detail. From these it may be noted that pH of rain water in the watershed range from 4 to 7; nitrate and sulfate levels in rain water were high only during the first storms of the season or during storms after long periods without rain; lead levels in rain water have decreased and zinc levels were higher than lead concentrations at all stations. In addition, elevated levels of grease and oil were found throughout Newport Bay and the watershed.
