Chemical Quality of Irrigation Waters in Hamilton, Kearny, Finney, and Northern Gray Counties

Abstract

One-hundred-ninety-nine pumping irrigation wells were sampled in Hamilton, Kearny, Finney, and northern Gray counties and adjoining portions of Wichita, Scott, Grant, Stanton, and Haskell counties during late July 1975. Saline water of a SO₄ type is found in the western three-fourths of the Arkansas River valley and a zone north of the river in Finney County. A better quality water of a Ca-HCO₃ type exists in the sandy regions south of the river. Localized variations exist in the Scott-Finney Depression area.

Compiled chemical quality data and chemical quality maps are presented for the study area.
