Avner Vengosh is a Professor of Environmental Quality at the Nicholas School of the Environment. Professor Vengosh and his team have studied the energy-water nexus, conducting pioneer research on the impact of hydraulic fracturing and coal ash disposal onthe quantity and quality of water resources. He has also investigated the sources and mechanisms of water contamination in numerous countries across the globe, including salinity and radioactivity in the Middle East, uranium in India, and hexavalent chromium in North Carolina and China. As part of these studies, his team has developed novel geochemical and isotopic tracers that are used as fingerprints to delineate the sources of water contamination and evaluate potential risks for human health. He is a Fellow of the Geological Society of America (GSA) and International Association of Geochemistry (IAGC). In 2019 and 2020, he was recognized as one of the Web of Science Highly Cited Researchers. He serves as an Editor of GeoHealth and on the editorial board of the journal Environmental Science and Technology.
