Patty Toccalino, Ph.D.
Patty Toccalino joined the USGS in 2005 and has nearly 25 years of interdisciplinary research, teaching, and leadership experience. Patty’s expertise lies at the interfaces between environmental chemistry, toxicology, risk assessment, and the fate and transport of contaminants in the environment. She is particularly interested in the occurrence and potential human-health significance of unregulated contaminants in water resources, including chemical mixtures and emerging contaminants. She led an interagency collaborative effort to evaluate water-quality data from the USGS National Water-Quality Assessment (NAWQA) Project in a human-health context and served on the USGS Environmental Health Strategic Science Planning Team. In 2010, Patty briefed Congressional staff on water-quality findings from public-supply wells in the United States. Beginning in 2016, she served as the Western Regional Program Officer for the National Water Quality Program.
Patty chaired the Dose-Response Specialty Group of the Society for Risk Analysis (SRA) in 2014, and has held multiple officer positions within SRA and the Pacific Northwest chapter of the Society of Environmental Toxicology and Chemistry. She served on the Centers for Disease Control Private Well Initiative National Workgroup, the Oregon Air Toxics Scientific Advisory Committee, and was an expert reviewer for EPA’s Contaminant Candidate List 3. Before joining USGS, Patty was an assistant professor at the Oregon Health & Science University. She previously taught at The Evergreen State College, and worked in industry (Chrysler Motors) and environmental consulting. Patty earned her B.S. in Environmental Health/Toxic Substance Control from Oakland University and her Ph.D. in Environmental Science and Engineering from the Oregon Graduate Institute.
