Abstract
Lithologic and ground-water data were collected at 85 monitoring sites constructed in the Mojave Water Agency Management area in San Bernardino County, California, as part of a series of cooperative studies between the U.S. Geological Survey and the Mojave Water Agency. The data are being used to evaluate and address water-supply and water-quality issues. This report presents a compilation of the data collected at these sites from 1992 through 1998, including location and design of the monitoring sites, lithologic data, geophysical logs, ground-water-level measurements, and water-quality analyses.One to five small (generally 2-inch) diameter wells were installed at each of the 85 monitoring sites to collect depth-dependent hydrologic data. Lithologic logs were compiled from descriptions of drill cuttings collected at each site and from observations recorded during the drilling of the borehole. Generalized stratigraphic columns were compiled by grouping similar lithologic units. Geophysical logs provide information on the character of the lithologic units and on the presence of ground water and the chemical characteristics of that water. Water-level and water-quality data were collected periodically from the sites during 1992 through 1998.
