Oregon Health & Science University
Dr. Paul G. Tratnyek is a professor in the Institute of Environmental Health at the Oregon Health & Science University. His research interests are associated with a wide range of oxidation-reduction reactions that occur in the environment, and the contribution of these reactions to the fate of organic pollutants. In most of his work, the focus is on pathways, kinetics, mechanisms and other fundamental molecular aspects of environmental chemistry. His research includes some of the earliest work on chemical reduction of contaminants, especially zero-valent iron. He is the principal investigator on several past and ongoing projects funded by SERDP related to aspects of abiotic natural attenuation, in situ chemical reduction, in situ chemical oxidation and redox characterization.
Dr. Tratnyek received a Bachelor’s degree in Chemistry from Williams College and a Ph.D. in Applied Chemistry from the Colorado School of Mines.
SESSION KEYNOTE PRESENTER - Oxidative and Reductive Treatments
Oxidation and Reduction: From Complementary Alternatives to Combined Remedies
Treatments based on oxidation and reduction are often considered to be opposites, with applicability to distinctly different contamination scenarios. However, they share several core concepts (e.g., aquifer oxidant and reductant demand), so there is efficiency and insight to be gained from considering oxidative and reductive treatments as complementary alternatives. Additional benefits might be gained by applying oxidation and reduction together, in combined remedies. However, optimization of such combined remedies is challenging, and requires uncommon understanding of how oxidation and reduction reactions interact.
