Effects of environmental change on groundwater recharge in the Desert Southwest Effects of environmental change on groundwater recharge in the Desert Southwest
Climate and other environmental conditions have varied in the past, and will almost certainly vary significantly in the near future. The response of groundwater recharge to changes in environmental conditions is thus a matter of active concem for water-resources management. The major mechanisms for this response of recharge are three-fold. First, changes in vegetation communities can...

Ground-water quality in the upper Santa Cruz Basin, Arizona, 1998 Ground-water quality in the upper Santa Cruz Basin, Arizona, 1998
Fifty-eight ground-water samples were collected and analyzed in 1998 by the U.S. Geological Survey and the Arizona Department of Environmental Quality to assess ground-water quality and to identify factors affecting ground-water quality in the Upper Santa Cruz Basin. In addition, pre-existing groundwater quality data for six wells were analyzed to determine changes in the ground-water...

Water quality in the central Arizona basins, Arizona, 1995-98 Water quality in the central Arizona basins, Arizona, 1995-98
The water quality in rivers and streams and in selected aquifers in central Arizona basins in Arizona is described and illustrated. Major ions, nitrogen and other nutrients, and pesticides and some of their breakdown compounds were analyzed in both surface and ground water. Biological communities that included fish, invertebrates, and algae, were described in relation to stream water...

Hydrogeologic investigations of the Sierra Vista subwatershed of the Upper San Pedro Basin, Cochise County, southeast Arizona Hydrogeologic investigations of the Sierra Vista subwatershed of the Upper San Pedro Basin, Cochise County, southeast Arizona
The hydrogeologic system in the Sierra Vista subwatershed of the Upper San Pedro Basin in southeastern Arizona was investigated for the purpose of developing a better understanding of stream-aquifer interactions. The San Pedro River is an intermittent stream that supports a narrow corridor of riparian vegetation. Withdrawal of ground water will result in reduced discharge from the basin...

Ground-water quality in alluvial basins that have minimal urban development, south-central Arizona Ground-water quality in alluvial basins that have minimal urban development, south-central Arizona
Ground-water quality data (1917-96) from 772 wells in 16 alluvial basins that have minimal urban development were used to determine the effect of nonurban factors on ground-water quality in south- central Arizona. Characterization of the spatial variability of ground-water quality within and among alluvial basins that have minimal urban development will provide a baseline to which water-...
