The primary objective of this study is a set of unified ground water chemical quality data for irrigation wells of the hydrogeologic observational network in west-central Kansas, i.e., southern Wallace, Greeley, Wichita, Scott, and Lane Counties. Compiled chemical quality data and chemical quality contour maps for the area of study are presented. This report represents the first of a program directed toward establishing base line chemical quality data for irrigation waters in western Kansas.

This study presents the third part of a program begun in 1974 to establish chemical quality base-line data for irrigation of western Kansas.
