My main research interests are understanding and integrating the basic processes which control the fate and transport of contaminants in the environment, particularly in groundwater. Our current understanding of these processes, or lack thereof, limits our ability to predict natural fate and to plan and conduct appropriate remediation of contaminated sites. Most of my current research has to do with transport and/or transformation of organic contaminants, including chlorinated solvents, hydrocarbons, pesticides and--recently--personal care products. This encompasses a broad range of problems. For example, our group is currently engaged in a study which tests how geologic-process based knowledge can improve our understanding of the composition and variability of aquifer properties as they relate to pollutant transport. In another study, we are investigating the transport pathways by which agricultural chemicals move within and out watersheds. One more example looks at how chemical oxidants used to remediate groundwater contaminants affect and are affected by the natural groundwater system. In addition to field investigation, my research includes laboratory experiments using gas chromatography for analysis of the organic compounds of interest. Analyses of sediments and water can also include: grain size; mineralogy; surface area and fraction organic carbon content; major cations and anions; and organic carbon content.
