Maps showing ground-water conditions in the San Simon area, Cochise and Graham Counties, Arizona, and in Hidalgo County, New Mexico — 1975

Arizona is divided into 67 ground-water areas, and individual areas are selected for intensive data collection once every 6 years. The data collected in the San Simon area are given on maps that show depth to water, well depth, and altitude of the water level, 1975; pumpage, 1915-74; and change in water level for 1964-75, hydrographs of the water level in selected wells, specific conductance, and fluoride concentration.
