All U.S. Government Documents (Utah Regional Depository)

This study is one of a series of studies appraising the water-bearing properties of the Navajo Sandstone and associated formations in southern Utah. The study area is about 4,600 square miles, extending from the Utah-Arizona State line northward to the San Juan-Grand County line and westward from the Utah-Colorado State line to the longitude of about 109 degrees 50 minutes.

Chemical Changes In Groundwater Of Northern Utah Valley, Utah, Paul E. Fairbanks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Northern Utah Valley is one of the fastest growing areas of Utah and has increasing needs for domestic, industrial, and agricultural water. To meet these needs, groundwater and surface water systems must be understood to maximize their use. Chemical studies of the sediment mineralogy and related water-chemistry give insight to the movement of the water.

There are three major aquifers present in the valley: shallow Pleistocene; deep Pleistocene; and Tertiary. They are composed of sands and gravels and are separated by confining layers (aquitards) composed mostly of clay. Along the flanks of the bordering mountains there are undifferentiated aquifers which …

Bedrock Aquifers In The Northern San Rafael Swell Area, Utah, With Special Emphasis On The Navajo Sandstone, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

The northern San Rafael Swell area in southeastern Utah includes about 2,880 square miles (7,460 square kilometers) and ranges in altitude from about 3,290 to 7,921 feet (1,195 to 2,414 meters). Precipitation, the main source of water in the area, ranges from slightly less than 6 inches (152 millimeters) to slightly more than 12 inches (305 millimeters). Rocks that underlie the area range from Precambrian to Holocene in age. The thickness of sedimentary rocks ranges from 4,083 feet (1,244 meters) to about 30,000 feet (9,140 meters). The Entrada, Navajo, Wingate, and Coconino Sandstones and rocks of Mississippian age are considered …
