Ground-water resources of Tooele Valley, Utah

Abstract

Ground water provides much of the water supply for residents of Tooele Valley (fig. 1). The protection, development, and wise management of ground-water resources are important to support community growth and to ensure the continued availability of ground water for all users. The U.S. Geological Survey, in cooperation with Tooele County, Tooele City, Grantsville City, the U.S. Army, and the State of Utah, has been studying the water resources of Tooele Valley since 1913 to define the quality and amount of water in the principal ground-water aquifers. The most recent studies in the 1990s have provided new insights into the hydrology of the valley. This fact sheet presents a synopsis of the recent studies and describes ground-water occurrence and movement, water quality, and a water budget for the principal basin-fill aquifer in Tooele Valley.
