Evaluating the Geohydrology in the San Gorgonio Pass Area

The San Gorgonio Pass, in southern California, is located between the San Bernardino and San Jacinto Mountain ranges. The mountain ranges to either side of the pass rise almost 9,000 feet (2,700 meters) above. The San Gorgonio Pass serves as a corridor for U.S. Interstate 10. It is also known for its strong winds that make it a popular spot for wind turbine energy production.

Water-Level, Water-Quality and Land-Subsidence Studies in the Mojave River and Morongo Groundwater Basins

Groundwater has been the primary source of domestic, agricultural, and municipal water supplies in the southwestern Mojave Desert, California, since the early 1900s. The population of the Mojave River and Morongo groundwater basins has grown rapidly during the last several decades, increasing from an estimated population of almost 273,000 in 1990 (Mojave Water Agency, 2004) to more than 453,000 in...

Water-resources study of Fort Irwin National Training Center

The U.S. Army at Fort Irwin National Training Center (NTC) obtains all of its potable water supply from Irwin, Langford, and Bicycle Basins within the base boundaries. Groundwater pumping, since as early as 1941, has resulted in water-level declines in all of these basins and the disposal of treated wastewater in the Irwin Basin has resulted in elevated nitrate concentrations in some wells in...
