Dream-Analytical Ground Water Flow Programs

Bemadine A. Bonn received a BS in chemistry and mathematics from the University of Portland in 1979 and an MAT from Lewis and Clark College in 1986. She is currently a PhD candidate in the Department of Environmental Science and Engineering at the Oregon Graduate Institute of Science and Technology. Ms. Bonn taught high school chemistry and mathematics for six years and is a Woodrow Wilson Fellowship Foundation Master Teacher. Her laboratory research, under the direction of Dr. William Fish, concerns the chemical and physical processes affecting inorganic contaminants in ground and surface waters. In addition, she is particularly interested in developing methods and materials to improve education in the environmental sciences. This commitment to improving teaching was a primary motivation in the development of DREAM. Stewart A. Rounds, a PhD candidate and NSF Graduate Fellow in the Department of Environmental Science and Engineering at the Oregon Graduate Institute of Science and Technology, received a RS in chemistry from the University of Illinois at Urbana in 1985. His research interests focus on the transport and transformations of organic chemicals in aqueous environments. Mr. Rounds’ undergraduate research, conducted with Dr. Richard A. Larson, centered on the photochemistry of 1-naphthol in aqueous systems and in surface microlayers. Now working under the direction of Dr. James F. Pankow, Mr. Rounds’ current research concerns the elucidation of the mechanisms controlling the rate-limited uptake and release of hydro-phobic organic compounds by soils and suspended sediments. This work will have important implications for models which predict the environmental fate of organic compounds. Mr. Rounds is also interested in the development of easy-to-use computer programs for environmental science applications. This, combined with his interest in hydrology and groundwater transport, was one of the driving forces for the creation of DREAM.
