Book excerpt: Excerpt from Sea-Water Intrusion in California: Inventory of Coastal Ground Water Basins The ground water supply of many urban communities adjacent to the coast of California is threatened by underground intrusion of saline water from the Pacific Ocean. This condition exists whenever ground water levels have been drawn down below sea level. To assist local agencies that must cope with this threat, the Department of Water Resources continually monitors wells in these areas to determine whether sea water has intruded the ground water basin. This is accomplished by testing the salt content of water samples from wells and measuring the fluctuation of water levels in wells. The primary purpose of this bulletin is to show, as completely as available information permits, the present status of seawater intrusion, to the end that local agencies can decide where they must take steps to reverse the condition. A corollary purpose is to show the need for more information on intrusion in certain areas where the situation is particularly critical. This study was undertaken solely to determine the extent and location of sea-water intrusion into coastal basins and to compile an inventory that would assist local agencies in assessing the water supply conditions in their areas. It was not designed to arrive at any specific conclusions or recommendations for on-site control of intrusion in individual basins. This effort is planned to encourage the formation of a cooperative statewide program to monitor coastal ground water basins. It is anticipated that the Department of Water Resources will meet with local agencies to develop such a program. As a minimum, it will require ground water quality sampling and measurements of water levels in wells. The Department recommends that coastal basins having known or suspected intrusion should be monitored at least every one to two years; basins containing high chlorides of doubtful origin should be monitored at least every three years; and the remaining basins should be surveyed about every five years.
