Scott Andres has been a hydrogeologist with the Delaware Geological Survey since 1984 during which time he has worked, published, and presented on a variety of ground and surface water projects and issues. Scott began a career in hydrogeology in 1980 with the New Jersey Department of Environmental Protection, where he was responsible for investigating ground-water pollution incidents.
Recent research efforts related to water resources have focused on effects of land based disposal of wastewater on soils, rocks, and ground and surface waters, nutrient cycling and watershed analyses for Delaware’s total maximum daily load program, ground-water modeling, submarine groundwater discharge, and large scale mapping and characterization of aquifer geometries and hydraulics. These efforts have included collaborative projects with researchers from other University of Delaware departments, other universities, U. S. Geological Survey, and Delaware Department of Natural Resources and Environmental Control.
Besides research, Mr. Andres participates in a number of advisory boards, working groups, review panels, and committees for government, academia, and professional societies. Over the years, Mr. Andres has trained and advised dozens of students that have gone on into water resources related careers in consulting, government, and academia.
Mr. Andres has a secondary appointment as Associate Professor in the Department of Geological Sciences in the College of Earth, Ocean, and Environment.
