A word or two about our speakers and their lecture
Professor Daniel McCurry
Dr. Daniel McCurry is an Assistant Professor of Civil and Environmental Engineering at the University of Southern California. Dr. McCurry completed his Ph.D. in Civil and Environmental Engineering with a Chemistry minor at Stanford in 2016. Prior to Stanford, he earned an M.S. in Environmental Engineering from Yale and a B.S. in Civil Engineering from the University of Cincinnati, and worked in the USEPA Office of Research and Development. Dr. McCurry's research focuses on protecting public health by improving the long-term safety of engineered water sources. He applies the tools of environmental organic chemistry to water quality problems arising from chemical and ultraviolet disinfection of wastewater and drinking water.
Applying Environmental Analytical Chemistry to Understand and Minimize Disinfection-Associated Carcinogens in Drinking Water and Recycled Wastewater
Disinfection of potable water is one of the great public health victories of the twentieth century, responsible for the avoidance of millions of deaths due to waterborne illness. However, application of disinfectants, typically chemical oxidants, leads to formation of hundreds of trace contaminants, often carcinogens, and consumption of chlorinated water has been epidemiologically linked to bladder cancer and certain birth defects. Eleven of these compounds are federally regulated in drinking water, but certain non-regulated disinfection byproducts (DBPs) are orders of magnitude more toxic than currently regulated compounds. Two specific DBPs, chloropicrin and N-nitrosodimethylamine (NDMA), are under current regulatory scrutiny and are associated with nitrogen input, often from wastewater discharges, into drinking water supplies, or deliberate reuse of wastewater. Wastewater-impacted drinking water and recycled wastewater are enriched in the precursors of these compounds, and their formation during potable water treatment is likely to grow, as wastewater increasingly contributes to the water supply. This presentation will focus on applying the tools of analytical and organic chemistry to identify the chemical precursors and formation mechanism of these compounds, leading to strategies for their control during water treatment.
Professor Valery Fokin
Valery V. Fokin received his Ph.D. degree in 1998 from the University of Southern California, where he worked under the direction of Professor Nicos A. Petasis. He then joined the group of Nobel Prize Winner Professor K. Barry Sharpless at The Scripps Research Institute in La Jolla, California as a postdoctoral fellow, where he studied catalytic oxidations of olefins. In 2001, he was appointed assistant, and in 2006 associate professor in the Chemistry Department at Scripps. His research is centered on understanding of the chemical reactivity and its applications in chemistry, biology, and materials science.
