Water Resources of the Dakota Aquifer in Kansas Appendix
Donald O. Whittemore, P. Allen Macfarlane, and Blake B. Wilson
Published online in 2015 as additional material for Kansas Geological Survey Bulletin 260. An Acrobat PDF version (29 MB) is also available.
The first of the following two sections provides additional detail for the determination of the locations and percent Dakota yield for wells pumping water from the Dakota aquifer with water rights (the section entitled "Location and Amount of Water Use" in the bulletin). The second section is an expanded version of the section on "Groundwater Geochemistry."
Acknowledgments
Several students and staff at the KGS contributed to the development of information and data on groundwater geochemistry as part of the Dakota Aquifer Program. Tyan-ming Chu conducted his Ph.D. dissertation on hydrogeochemical processes in the Dakota aquifer, including numerical modeling of the evolution of groundwater geochemistry, especially as affected by cation exchange. He also participated with the author of this appendix in the collection of some of the samples from water-supply wells in the Dakota aquifer. Rogheyeh Eskrootchi, Elizabeth Grieve, Xiaodong Jian, Brian Wardlow, Brownie Wilson, and John Woods worked on or assisted in various aspects of the chemical data base and generation of regional maps of chemical constituents in Dakota aquifer waters. Roger Boeken determined resistivities from geophysical logs in northwest Kansas for estimating total dissolved solids concentration in the Dakota aquifer where there are no or very little sample data and used the study for his M.S. thesis. Don Butcher, Kansas Corporation Commission, collected samples from Hays test wells, and staff of Ground Water Associates, Inc. of Wichita sampled water from Russell County test wells and provided them to the KGS. R. D. Black, School of Engineering, Kansas State University, collected water samples during an energy use study of high-capacity wells in the Dakota aquifer and had the soils test laboratory at Kansas State University analyze the samples for selected constituents. Lawrence Hathaway, Karmie Galle, Truman Waugh, and Masato Ueshima analyzed the water samples collected by or sent to the KGS for chemical constituent concentrations. Mark Schoneweis assisted in the final graphics for some of the figures. Julie Tollefson edited and produced the final publication. The authors appreciate the reviews of this appendix by Scott Ross, Division of Water Resources, Kansas Department of Agriculture, Susan Stover, Kansas Water Office, and Mark Rude, Southwest Kansas Groundwater Management District No. 3, and earlier reviews of the geochemistry section by Dr. Robert Cullers, Department of Geology, Kansas State University, and Dr. George Schurr, GeoSchurr Resources LLC, Ellsworth, Minnesota.
