Water Quality in the Sierra Vista Subbasin, Southeastern Arizona: A Baseline for the Futureby G. Cordy,
Abstract: As part of the U.S. Geological Survey's (USGS) National Water-Quality Assessment program, water-quality studies were completed in the Sierra Vista subbasin in southeastern Arizona during 1996-98. In addition to analyses of major ions, nutrients, trace elements, and pesticides in ground water and surface water, the concentrations of selected organochlorine compounds in bed sediment and fish tissue of the San Pedro River were determined.
