Ground-water conditions at Beale Air Force Base and vicinity, California

The U.S. Geological Survey was asked by the Air Force to make a study of ground-water conditions at the base. This report and an earlier data report have resulted from the study.

The purpose of the study was to appraise the ground-water resource in the vicinity of Beale Air Force Base with regard to source, occurrence, movement, and chemical quality. This information will be used in the long-term management of the water supply for the base.

The scope of the study included identifying zones of poor-quality water that could affect the base water supply and providing suggestions for changes in pumping, well construction, and well-site selection that would improve the reliability of the water supply.

Source material included drillers’ logs, chemical analyses of ground water, water-level records, pumpage records, and previously published reports for the area.
