Steve Esling, Lecturer, Associate Professor Emeritus



  • B.S. 1975, Illinois State University
  • M.S. 1982, University of Iowa
  • Ph.D. 1984, University of Iowa

Research Interests:

Steven P. Esling blends his background in mathematics and geology with his interests in hydrogeology and Quaternary stratigraphy.  His efforts have led to studies quantifying erosion rates in strip mine spoils, assessing the impact of agricultural drainage wells on shallow bedrock aquifers, determining the effect of underground refuse disposal on regional groundwater flow systems, and investigating the migration of contaminant plumes through shallow aquifers.
