Description:
Data collected for this study include ground water chemical
analysis, drillers" logs of water wells, geohydrologic and
geologic information. Published chemical analysis were compiled
from Witcher, 1981; Swanberg and others, 1977; Muller and others,
1973; Dutt and McCreary, 1970; and Hem, 1950. Additional analysis
from an area near Buena Vista were obtained from a University of
Arizona Master's thesis on a sub-economic mineral deposit
(Yarter, 1981). Knechtel (1938) published several analysis from
the area in a U.S. Geological Survey Water Supply Paper.
Knechtel"s data were not included in our data base because they
were relatively incomplete. Unpublished chemical analyses were
obtained from files of the city of Safford"s engineers" office
and from files of the U. S. Geological Survey, Water Resources
Division, Tucson. Because available published and unpublished
chemical analysis usually had no aluminum, boron, or lithium
analysis and because reliability of pH and alkalinity data were
generally unknown, field collection of an additional 42 chemical
analysis of ground water was performed.
Drillers' logs and geohydrologic information were obtained from
Knechtel, 1938; Witcher, 1982; and from files of the Arizona
Department of Water Resources, Phoenix and the U. S. Geological
Survey, Water Resources Division, Tucson.
