Rogheyeh Eskrootchi assisted in the development of a data base for Dakota water chemistry. John Woods and Rogheyeh Eskrootchi helped in the development of the regional water-quality maps of the aquifer. Others who participated in mapping and data activities included student assistants Elizabeth Greive, Xiaodong -LDQDQG%ULDQ:DUGORZ0DUN6FKRQHZHLVSURYLGHGJUDSKLFVIRUVRPHRIWKH¿JXUHV 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 in the collection of samples from water-supply wells in the Dakota aquifer. 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. Lawrence Hathaway, Karmie Galle, Truman Waugh, and Masato Ueshima analyzed water samples collected by or sent to WKH.*6-XOLH7ROOHIVRQHGLWHGDQGSURGXFHGWKH¿QDOSXEOLFDWLRQ-LP%XWOHUUHYLHZHG and commented on a draft of this document. The authors appreciate the comments and edits of Scott Ross, retired, Division of Water Resources, Kansas Department of $JULFXOWXUH6XVDQ6WRYHU.DQVDV:DWHU2I¿FHDQG0DUN5XGH6RXWKZHVW.DQVDV Groundwater Management District No. 3, who reviewed the current document, and also those of Robert Cullers, retired, Kansas State University, and Daniel Schurr, GeoSchurr Resources LLC, Ellsworth, Minnesota, who reviewed an earlier, expanded version of the geochemistry section.
