My research addresses how to improve our capacity to make reliable and practical predictions of contaminant fate and transport in groundwater systems. The goal of this research is to better understand the threats posed to our groundwater resources and to better protect those resources. My research has included field and modeling investigations of the fate and transport of herbicides in groundwater, delineation of source-water protection areas and development of new techniques to quantify the uncertainty of model predictions and laboratory and modeling investigations of the transport of E. coli bacteria through unconsolidated aquifers material. My latest research focus has been on groundwater/surface-water interaction and investigating the role of the riverbed in controlling riverbank filtration and induced infiltration. This research has involved field experiements in local well fields and groundwater-flow modeling of those sites. It has also involved testing and development of techniques to measure groundwater/surface-water exchange using a large-scale outdoor laboratory aquifer housed at Miami's Ecology Research Center. In addition to the local research, I am also interested in water-quality problems in the industrially-developing world. This interest has led to research and development of new research opportunities in Nepal, Kenya, Zambia and Namibia. |
