Sandra M. Eberts, a professional hydrogeologist with the U.S. Geological Survey for whom she’s worked for more than 25 years, has experience developing and leading multidisciplinary scientific programs at the national level. She serves as the USGS representative to the Source Water Collaborative — 25 national organizations united to protect America’s sources of drinking water — and also coordinates the USGS National Water-Quality Assessment Program, Groundwater Modeling & Mapping Team. In 2013, Eberts coauthored USGS Circular 1385, Factors Affecting Public-Supply-Well Vulnerability to Contamination: Understanding Observed Water Quality and Anticipating Future Water Quality, which summarizes 10 years of work on public-supply-well vulnerability and water quality conducted by more than 30 USGS scientists. Eberts’ background includes water quality and quantity assessments ranging from the plume-scale to the principal aquifer-scale. Her current research interests include providing a flow-system context for groundwater-quality data. Eberts holds a B.S. and M.S. in geology from Ohio State University and a certificate in legislative studies from Georgetown University.
