Report Title: Water type and suitability of Oklahoma surface waters for
public supply and irrigation Part 5: Washita River basin through 1979
Report Number: WRI 82-29
Author: Jerry D. Stoner
Abstract
Water-quality data through 1979 in the Washita River basin within
Oklahoma were examined for water type and suitability for public water
supply and for irrigation use. Of 82 stations with available data, 32
stations or 39 percent were considered to have sufficient data for
analysis. The classification of water type was based on the relation
of the major ions: calcium, magnesium, sodium, carbonate, bicarbonate,
sulfate, and chloride to each other within the range of measured
specific conductance. The suitability for use as a public supply was
based on the concentration distribution of selected constituents. The
constituents selected were those with maximum contaminant levels
established by regulation, or constituents for which recommended
maximum limits have been established and for which historic data are
available. The irrigation classification method of Wilcox was used to
relate sodium, calcium, and magnesium concentrations and the salinity
distribution to the suitability for use of the water for
irrigation. Where data were available, the chance of phytotoxic
effects by boron was discussed.
