Appendix B

Table B1. Discharge, specific conductance, and sulfate, chloride, and total dissolved solids (TDS) concentrations for the Arkansas River near Coolidge. Data are from the U.S. Geological Survey (USGS), Kansas Department of Health and Environment (KDHE), and the Kansas Geological Survey (KGS). TDS concentrations computed from the sum of the concentrations of major dissolved constituents are included in the column with TDS measured by evaporation to dryness. The estimated TDS values are computed from the relationship of specific conductance and TDS concentration derived from KGS data.
