U.S. Geological Survey ground-water studies in Utah

Abstract

Ground water is an important natural resource in Utah. In the basins west of the Wasatch Front, and in many other parts of Utah, ground water is the primary source of water. In many of the basins of the western desert and in parts of the Colorado Plateau, ground water is the only reliable source of water. Along the Wasatch Front to the north and south of Salt Lake City, in the Uinta Basin, and in the Sevier River drainage, surface water is the primary source of water. Ground-water sources supply about 20 percent of all water used in Utah and about 63 percent of the water for public supply. Of the total amount of ground water used, 44 percent is for irrigation, 35 percent is for public supply, 11 percent is for industry, 5 percent is for rural domestic supplies, and 5 percent is for livestock. The major issues related to ground water in Utah are: -Development of additional ground-water supplies while protecting existing water rights and minimizing effects on water levels, water quality, and streamflow, and -Protection of ground-water resources from contamination by pollutants from various types of land-use and waste-disposal practices.
