David Sedlak is a Malozemoff Professor in Mineral Engineering, Co-director of Berkeley Water Center, and Director of Institute for Environmental Science and Engineering (IESE). Professor Sedlak's research focuses on fate of chemical contaminants, with the long-term goal of developing cost-effective, safe, and sustainable systems to manage water resources. He is particularly interested in the development of local sources of water. His research has addressed water reuse--the practice of using municipal wastewater effluent to sustain aquatic ecosystems and augment drinking water supplies--as well as the treatment and use of urban runoff to contaminated groundwater from contaminated industrial sites as water supplies. In recent years, his research on the fate of wastewater-derived contaminants has received considerable attention. He began this research in 1996 when he developed simple methods for measuring steroid hormones in wastewater. Since that time, he and his students have studied the fate of hormones, pharmaceuticals, toxic disinfection byproducts and other chemicals. His research team has also studied approaches for remediating contaminated soil and groundwater by in situ chemical oxidation (ISCO) and advanced oxidation processes.
