The Earth and Environmental Science Seminar Series presents: "Adventures in STEM: From radioactive waste disposal to beneficial use of coal fly ash, and beyond..." with Dr. Tim Dittrich, PhD, Professor of Civil and Environmental Engineering at Wayne State University, where he just joined the faculty in Fall 2017. He received his BS in Biological Systems Engineering from the University of Wisconsin-Madison, MS in Biological and Environmental Engineering from Cornell University, and PhD in Civil and Environmental Engineering from the University of Colorado-Boulder. He was a postdoctoral scholar at Los Alamos National Laboratory in Los Alamos, NM for 3 years and a staff scientist for 2 years. His research interests are in the areas of contaminant geochemistry, treatment of contaminated water and soil using natural systems, sustainable urban development, and development of hazardous waste treatment strategies.

Abstract: The U.S. currently has hundreds of thousands of tons of nuclear waste that require permanent geologic disposal and over 100 contaminated sites that require remediation. Many significant scientific and engineering challenges remain to ensure safe waste disposal and to clean up contaminated sites. Dr. Dittrich studies the fundamental physical, geochemical, and biological processes that control solubility, sorption, and transport of radionuclides and other co-contaminants and applies these concepts to evaluate systems for the safe disposal of nuclear waste. Dr. Dittrich will present a brief overview of the only operating nuclear repository in the U.S. for transuranic waste (the Waste Isolation Pilot Plant in southeastern, NM) and will discuss transport and removal processes of radionuclides in porous media and how sorption kinetics play a major role in transport potential and risk assessment. This seminar will also discuss how understanding fundamental sorption processes can be used to engineer enhanced sorption media to address the efficacy of using coal fly ash (the material left after burning coal for electricity) as a resource for rare earth element extraction, along with other applications.
