Work Assignment

As a hydrologist in the National Research Program of WRD I conduct long-term research on the fate and geochemical effect of organic contaminants in subsurface environments. I use a combined field and laboratory approach in a variety of hydrogeologic environments in order to meet these objectives.  I am currently a principal investigator for projects at the Bemidji, MN and Norman, OK research sites and am investigating the potential environmental impacts of wastewaters from hydraulic fracturing.  My research at these sites focuses on the long-term evolution of biogeochemical zones in the aquifers and the natural attenuation of contaminants.  The impact of chemical heterogeneity and the availability of electron acceptors on the extent of biodegradation have been a major thrust of my work.  I have also studied contaminated aquifers in Pensacola, FL and Galloway, NJ, with an emphasis on understanding the fate of metabolites in shallow aquifers.

Biogeochemical Controls on Organic Contaminant Degradation in Heterogeneous Near Surface Environments

Quantifying the coupled hydrogeological, microbiological and geochemical processes that control natural attenuation and the redox potential of subsurface systems is fundamental to understanding contaminant transport and protecting drinking water and ecosystem health. Despite the well-recognized importance of mixing interfaces, few field investigations of contaminated systems have targeted these narrow, highly transient zones due to difficulties in obtaining representative hydrologic, geochemical, and microbiological measurements at relevant spatial and temporal scales.

I use a combined field and laboratory investigative approach to assess the link between hydrology, geochemistry, organic carbon degradation, and the microbial community composition and function and study the relationship between processes at mixing interfaces such as recharge/plume and ground water/surface water boundaries. Using a multi-disciplinary and multi-scale approach I develop conceptual models that link organic carbon degradation to physical, chemical, and biological processes in complex hydrogeological environments in order to provide a comprehensive picture of organic carbon transformation processes in surficial aquifers.
