Abstract
In 1990, as part of a national presidential initiative on water quality, researchers from the University of Nebraska-Lincoln (UNL) Institute of Agriculture and Natural Resources (IANR) received a multi-year grant from the United States Department of Agriculture, Cooperative State Research Service, to study management of irrigated com and soybeans to minimize groundwater contamination. D.G. Watts, R.F. Spalding, and J.S. Schepers, of the IANR led a study at one of the Management Systems Evaluation Areas (MSEA). This area was made up of two sites, a primary site on a terrace of the Platte River near Shelton and a secondary site nearer the river. R.F. Diffendal, Jr., research geologist with the UNL Conservation and Survey Division (CSD), was responsible for collecting samples from and geophysically logging a series of boreholes drilled by Bob Pollack, of Pollack Well Drilling, Grand Island, Nebraska, at the primary site and for using these data to characterize the site geology. Diffendal was assisted in the sampling and logging by hydrogeologist Frank A. Smith and technician Kenneth A. Hueske, both of CSD. Raw geophysical data from the boreholes was converted to a standard format by Jerry F. Ayers, CSD research hydrogeologist. Samples and logs from the boreholes and from others drilled and logged later by other researchers were studied, analyzed, and interpreted as part of this investigation.
