Chlorinated Hydrocarbons: Emerging Implications In Regional Planning TIMOTHY G. SHEA, Assistant Manager WILLIAM E. GATES, Manager Research and Development Laboratory Engineering-Science, Inc. Oakland, California INTRODUCTION The San Francisco Bay-Delta System consists of two major estuaries which are confluent in Central San Francisco Bay and which empty through the Golden Gate into the Pacific Ocean (Figure 1). The Northern Estuary consists of San Pablo and Suisun Bays and the Sacramento-San Joaquin River Delta; the Southern Estuary consists of Southern San Francisco Bay and Lower San Francisco Bay. The major fresh water inflow to the Bay-Delta is derived from the runoff of the Sacramento and San Joaquin Rivers which drain the agriculturally-rich Central Valley of California. Essentially no fresh water inflow to the Southern Estuary occurs in the summer and fall months other than the treated waste discharges of nearly 3,000,000 people who reside contiguous to the shores of the Southern Estuary. The San Francisco Bay-Delta Water Quality Control Program was conducted during 1966-1968 with the objectives of assessing the magnitude and effects of wastewater discharges in the 12-county region encompassing San Francisco Bay, and to develop plans for achieving water quality management on a regional basis through year 2000. In conjunction with the Bay-Delta Program, a review was made of available information describing the sources and fate of chlorinated hydrocarbons in the San Francisco Bay hydrographic and lithographic system. It was found that a considerable body of information on chlorinated hydrocarbons in agricultural drainage from the Central Valley of California had been developed by the Department of Water Resources, State of California, and by the FWPCA , after 1963, some of which have been published (1,2). However, no information was available to permit estimation of the quantities of chlorinated hydrocarbons entering San Francisco Bay from municipal and industrial sources or of the quantities of chlorinated hydrocarbons from municipal, industrial, and agricultural sources being transported through or accumulating in San Francisco Bay. Because of the continuing and increasing use of chlorinated hydrocarbons in products for agricultural, domestic, and industrial uses, and because of the growing concern about these compounds in the environment, more complete information on the sources and fate of chlorinated hydrocarbons in the Bay-Delta was required before recommendations for a regional water quality policy for these compounds could be formulated. The objectives of this study were: 1) to develop estimates of chlorinated hydrocarbon emissions in municipal and industrial wastewaters, 2) to update and expand data on levels of chlorinated hydrocarbons in water and sediments in the Bay-Delta region, and 3) to formulate a mass balance of pesticide transport into and from the San Francisco Bay System.
