Chemical quality of ground water in Salt Lake Valley, Utah, 1969-85
K.M. Waddell, R. L. Seiler, D. K. Solomon
1986, Open-File Report 86-138
During 1979-84, 35 wells completed in the principal aquifer in the Salt Lake Valley, Utah, that had been sampled during 1962-67 were resampled to determine if water quality changes had occurred. The dissolved solids concentration of the water from 13 of the wells has increased by more than 10% since...
Three-dimensional model simulation of steady-state ground-water flow in the Albuquerque-Belen Basin, New Mexico
J. M. Kernodle, W. B. Scott
1986, Water-Resources Investigations Report 84-4353
As part of the Southwest Alluvial Basins study, model was constructed to simulate the alluvial aquifer system underlying the Albuquerque-Belen Basin. The model was used to simulate the steady-state flow condition assumed to have existed prior to 1960. Until this time there apparently were no long-term groundwater level changes of...
Water demands in Kansas, 1944-84
J. F. Kenny
1986, Water-Resources Investigations Report 86-4038
The State of Kansas has administered water rights according to an appropriations doctrine since 1945. Water rights are issued by the Kansas State Board of Agriculture, Division of Water Resources, for eight categories of beneficial use. Water rights data and limited information on reported water use are stored on a...
