Ground Water Recharge at the Orange County Water Districtby Nereus Richardson, Orange County Water District, United States,
Abstract: In the early part of the century, upstream diversions from the Santa Ana River were reducing the flows to Orange County resulting in less recharge to the Basin and increased pumping of ground water. The ground water levels in Orange County were therefore dropping rapidly, resulting in seawater intrusion into the fresh water aquifers. The District eventually resolved the Santa Ana River water rights issue in a 1969 stipulated judgement and has developed extensive surface water recharge systems and seawater intrusion barriers. With the continued population growth in Orange County, the District is expanding its efforts to develop additional local water and implement water quality projects to maximize a ground water management program.
