Tom McKenna joined Delaware Geological Survey in 1997. Dr. McKenna holds a Ph.D. from the University of Texas at Austin, an M.S. from The University of South Carolina, and a B.S. from The Richard Stockton College of New Jersey. He previously worked as a consulting hydrogeologist for Geraghty & Miller in Tampa, Florida and Exxon Production Research in Houston, Texas.
Dr. McKenna's primary research and service is within the field of hydrogeology with a focus on the water resources of Delaware. General research topics include ground-water/surface-water interaction, aquifer characterization, heat transport, and the evaluation of the quantity and quality of water resources. Research consists of field and modeling studies using optical and thermal remote sensing from satellite, aerial, and ground-based platforms, surface and borehole geophysics, time-series and spatial analyses (GIS), and modeling of ground-water flow and heat transfer. Heat is used as a tracer of hydrologic processes and as a proxy for hydrologic and thermal properties.
Dr. McKenna has a secondary appointment as Associate Professor in the Department of Geological Sciences in the College of Earth, Ocean, and Environment. He has taught the Hydrogeology course and other seminar classes for the Department of Geological Sciences and the Geographic Information Systems class for the Department of Geography.
