Excerpt from Preliminary Assessment of Sources, Distribution, and Mobility of Selenium in the San Joaquin Valley, Calfornia Can the water table be controlled by managing irrigation practices and ground-water withdrawals in order to reduce the need for drainage? How much selenium is reaching the San Joaquin River, and is it having adverse effects on the river, the sacramento-san Joaquin Delta, or San Francisco Bay? These and other related questions are partially answered in this report on the basis of presently available information. Careful consideration of present knowledge in relation to these questions provides information and guidance to water managers and aids in modifying and prioritizing goals for future study.
