Education
Attended Wabash College, Purdue University (B.S. 1983), Indiana University (M.S. 1987, Ph.D. 1994).
Received a B.S. from Purdue University with a geology major and mathematics minor.
Received a M.S. from Indiana University with a major in hydrogeology and a minor in numerical methods. The M.S. thesis used numerical modeling to verify field evidence of ice-sheet surging during the Pleistocene epoch.
Received a Ph.D. from Indiana University with a major in hydrogeology and a minor in geochemistry. The Ph.D. dissertation used hydraulic and geochemical modeling to determine that hydrated iron-sulfate minerals were responsible for acute acid-mine drainage events.
Horizontal Borehole Flowmeters
Horizontal borehole flowmeters may provide opportunities to measure the rate and direction of groundwater flow and the advective transport of dissolved and neutrally buoyant contaminants. Optical, acoustic, thermal, and chemical technologies are being evaluated. Research is directed toward defining the limits of each technology and the environmental and hydrologic conditions that are best suited for each tool. Testing has been done in field settings and laboratory aquifer simulators.

Effects of highway-deicer application on ground-water quality in a part of the Calumet Aquifer, northwestern Indiana
The effects of highway-deicer application on ground-water quality were studied at a site in northwestern Indiana using a variety of geochemical indicators. Site characteristics such as high snowfall rates; large quantities of applied deicers; presence of a high-traffic highway; a homogeneous, permeable, and unconfined aquifer; a shallow water table; a known ground-water-flow direction; and minimalAuthorsLee R. Watson, E. Randall Bayless, Paul M. Buszka, John T. WilsonUse of isotopes to identify sources of ground water, estimate ground-water-flow rates, and assess aquifer vulnerability in the Calumet region of northwestern Indiana and northeastern Illinois
Isotope data collected in the Calumet Region of northwestern Indiana and northeastern Illinois, one of the most heavily industrialized regions of the United States, indicated that water in the surficial Calumet aquifer is well mixed. The Calumet aquifer is recharged areally by precipitation and locally may be recharged by surface water. The residence time of ground water in the Calumet aquifer isAuthorsRobert T. Kay, E. Randall Bayless, Robert A. SolakAn evaluation of borehole flowmeters used to measure horizontal ground-water flow in limestones of Indiana, Kentucky, and Tennessee, 1999
Three borehole flowmeters and hydrophysical logging were used to measure ground-water flow in carbonate bedrock at sites in southeastern Indiana and on the west-central border of Kentucky and Tennessee. The three flowmeters make point measurements of the direction and magnitude of horizontal flow, and hydrophysical logging measures the magnitude of horizontal flowover an interval. The directionalAuthorsJohn T. Wilson, Wayne A. Mandell, Frederick L. Paillet, E. Randall Bayless, Randall T. Hanson, Peter M. Kearl, William B. Kerfoot, Mark W. Newhouse, William H. PedlerAtrazine retention and degradation in the vadose zone at a till plain site in central Indiana
The vadose zone was examined as an environmental compartment where significant quantities of atrazine and its degradation compounds may be stored and transformed. The vadose zone was targeted because regional studies in the White River Basin indicated a large discrepancy between the mass of atrazine applied to fields and the amount of the pesticide and its degradation compounds that are measured iAuthorsE.R. BaylessIsotope hydrology dynamics of riverine wetlands in the Kankakee Watershed, Indiana
Wetland restoration activities may disturb shallow ground-water flow dynamics. There may be unintentional sources of water flowing into a constructed wetland that could compromise the long-term viability of a wetland function. Measurement of naturally-occurring isotopes in the hydrosphere can provide an indication of provenance, flow paths or components, and residence times or ages of wetland grouAuthorsW.C. Sidle, L. Arihood, R. BaylessAnalysis of atrazine and four degradation products in the pore water of the vadose zone, central Indiana
A new method is described for the analysis of atrazine and four of its degradation products (desethylatrazine, deisopropylatrazine, didealkylatrazine, and hydroxyatrazine) in water. This method uses solid- phase extraction on a graphitized carbon black cartridge, derivatization of the eluate with N-methyl-N-(tert-butyldimethylsilyl)trifluoroacetamide (MTBSTFA), and analysis by gas chromatography/mAuthorsS.Y. Panshin, D.S. Carter, E.R. BaylessEnvironmental setting and natural factors and human influences affecting water quality in the White River Basin, Indiana
The White River Basin drains 11,349 square miles of central and southern Indiana and is one of 59 Study Units selected for water-quality assessment as part of the U.S. Geological Survey's National WaterQuality Assessment Program. Defining the environmental setting of the basin and identifying the natural factors and human influences that affect water quality are important parts of the assessment.AuthorsDouglas J. Schnoebelen, Joseph M. Fenelon, Nancy T. Baker, Jeffrey D. Martin, E. Randall Bayless, David V. Jacques, Charles G. CrawfordA Study of Natural and Restored Wetland Hydrology
The U.S. Geological Survey and the U.S. Environmental Protection Agency are jointly studying the hydrology of a long-existing natural wetland and a recently restored wetland in the Kankakee River Valley in northwestern Indiana. In characterizing the two wetlands, project investigators are testing innovative methods to identify the analytical tools best suited for evaluating the success of wetlandAuthorsE. Randall Bayless, Leslie D. Arihood, William C. Sidle, Noel B. PavlovicHydrology and geochemistry of a slag-affected aquifer and chemical characteristics of slag-affected ground water, northwestern Indiana and northeastern Illinois
Slag is a by-product of steel manufacturing and a ubiquitous fill material in northwestern Indiana. Ground water associated with slag deposits generally is characterized by high pH and elevated concentrations of many inorganic water-quality constituents. The U.S. Geological Survey, in cooperation with the Indiana Department of Environmental Management, conducted a study in northwestern Indiana froAuthorsE. Randall Bayless, Theodore K. Greeman, C.C. HarveyWater quality of selected streams in Montgomery County, Indiana, 1996
The USGS sampled streams in Montgomery County as part of a study done in cooperation with the Montgomery County Commissioners. The sampling program was designed by the Montgomery County Sanitarian and USGS hydrologists. The program focused on assessing general surface-water quality throughout the county and also targeted some specific areas of interest to county officials.AuthorsHydrogeology and simulated ground-water flow through the unconsolidated aquifers of northeastern St. Joseph County, Indiana
The U.S. Geological Survey investigated ground-water resources of northeastern St. Joseph County, Indiana, during 1990-93. The investigation included field measurements of water levels and numerical models of ground-water flow. This report documents results of that work and includes descriptions of (1) hydrogeologic framework, (2) water levels, (3) model sensitivity to variations in hydrogeologicAuthorsE. Randall Bayless, L. D. ArihoodGround-water quality in northeastern St. Joseph County, Indiana
This report describes the ground-water quality of a 220-square-mile area in northeastern St. Joseph County, Indiana. Ground-water samples were collected from 30 monitoring wells at 20 sites during May 1992; the wells were screened in either a shallow or a deep sand and gravel aquifer. Samples were analyzed for general water-quality properties, nutrients, major ions, trace elements, industrial orgaAuthorsJ.M. Fenelon, E. Randall Bayless, Lee R. WatsonNon-USGS Publications**
