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. Much of my latest research focuses on groundwater/surface-water interaction and investigating the role of the riverbed in controlling riverbank filtration and induced infiltration. I have also been exploring palygorskite clay as a potential filter medium for removing pharmaceuticals from sewage treatment plant effluent. In addition, I am also interested in water-quality problems in the industrially-developing world. This interest led to research and development of new research opportunities in Nepal, Kenya, Zambia, and Malawi.
