Dr. David Reisman, currently a Senior Technical Advisor for CDM Smith, a full-service consulting, engineering, construction, and operations firm, and the previous Director, Engineering Technical Support Center, National Risk Management Research Laboratory, U. S. Environmental Protection Agency. Mr. Reisman worked for the U. S. Government from 1976-2012 with the National Park Service (Park Ranger), the National Institute for Occupational Safety and Health (Information Specialist), and in many positions with the Environmental Protection Agency (EPA). He served for several years as a Temporary Advisor to the World Health Organization (WHO) in Geneva, Switzerland, authored many environmental health criteria documents for both EPA and WHO, and published over 50 peer-reviewed journal articles, many in the area of remediation and mining influenced water treatment. David holds a Masters Degree in interdisciplinary environmental sciences from Miami University, and has completed additional graduate work in engineering at the University of Cincinnati. For over 15 years, David assisted in the development of risk assessment guidance for the EPA Office of Research & Development in the waste, ambient and drinking water and hazardous air pollutants areas. As Director of the EPA's Engineering Technical Support Center for almost 15 years, David worked on several hundred hazardous waste sites, conducted treatability and pilot technology studies, and assisted EPA regional personnel and contractors in site characterization, soil remediation, technology selection and treatability study design. David is the recipient of many Government awards and has received several medals for his outstanding work in supporting EPA's regional personnel. Mr. Reisman will lecture on soil remediation principles, technologies and techniques.

Dr. David Jewett is a hydrogeologist with over 25 years of site characterization and subsurface remediation experience in government, industry, and academia. Dr. Jewett is the Director of the U.S. EPA's National Risk Management Research Laboratory, Ground Water and Ecosystems Restoration Division located in Ada, Oklahoma. Dr. Jewett leads a team of geochemists, environmental scientists, environmental engineers, hydrogeologists, microbiologists, and soil scientists conducting research and providing technical support related to site characterization and remedial technology development, evaluation, and implementation at hazardous waste sites in order to protect and restore ground water, surface water, and ecosystem resources. His research interests include site characterization techniques, contaminant fate and transport, ground water flow and solute transport modeling, and ground water/surface water interactions. Dr. Jewett was a hydrologist specializing in applied research and technical support and the former Director of the U.S. EPA's Center for Subsurface Modeling Support before accepting the responsibilities as Chief of the Subsurface Remediation Branch. Dr. Jewett has a B.S. in geology from Syracuse University, a M.S in geology from The Wichita State University, and a Ph.D. in hydrology from the Department of Hydrology and Water Resources at The University of Arizona. Prior to joining the U.S. EPA, Dr. Jewett was on the faculty of the Department of Geology at Indiana University Purdue University Indianapolis. He also has several years experience as a hydrogeologist and project manager in the environmental remediation industry. Dr. Jewett will lecture on groundwater remediation techniques and strategies through comparisons and case studies highlighting: Air Sparging; Dynamic Vapour Extraction; Flushing/Stripping; Source Removal; Bioremediation; Bioslurping; UV/Ozone/Hydrogen Peroxide Oxidation; Granular Activated Carbon Systems; Air Strippers; Oxygen Enhancement; Zero-Valent Iron (Funnel-and-Gate) and Physical and Hydraulic Containment.
