A. Scott Andres

EXPERTISE

---

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 nutrient loading analysis for the total maximum daily load efforts in the Inland Bays and Nanticoke watersheds, relationships between ground-water quality and land use, ground-water modeling for wellhead protection area delineations, and mapping and characterization of ground-water recharge potential, water-table elevation, and aquifers. These efforts have included collaborative projects with researchers from other University of Delaware departments, 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 Professor in the College of Marine and Earth Studies.
