A systems analysis approach to evaluation of alternative plans for control of quality in a major Southern California ground-water basin is described. Mathematical models of basin hydrologic behavior and water quality response are to be used conjunctively with an economic model to find the least costly plan which will produce acceptable quality over the entire basin throughout a 30-yr planning horizon. Historic water quality changes are presented and a strategy for assessment of changes predicted by the models is outlined.
