Map showing general chemical quality of ground water in the Salina quadrangle, Utah

The general chemical quality of water was determined from quality-of-water data collected by the U.S. Geological Survey and cooperating State, local, and Federal agencies. Sources of data include springs, and wells that tap aquifers at depths of less than 1,000 feet. In areas where quality-of-water data are inadequate or lacking, the limits of dissolved solids are inferred from geologic data. More exact determination of the chemical quality of ground water in any given part of the map area can be made only on the basis of special investigations. More detailed information on the chemical quality of ground water in specific areas is obtainable from the district office of the Water Resources Division, U.S. Geological Survey, Salt Lake City, Utah.
