Research
Hydrogeology, including modeling carbon sequestration, groundwater flow and contaminant transport, and flow and transport in unsaturated soils; oil and DNAPL monitoring and recovery; remediating PCB-contaminated sediments; well design, construction, and hydraulic testing; and heat transport and storage in the shallow subsurface.
My primary research areas are (1) modeling carbon sequestration in deep saline aquifers, and (2) improving free product monitoring and recovery in wells and trenches. I also have interest in (3) remediating PCB-contaminated river and lake sediments, and (4) slug-test analysis methods. (1) We have tested the predictive ability of contaminant transport models that work with MODFLOW. We have used the STOMP code to model injection of supercritical CO2 into brine-filled rock layers over one-half mile deep in Michigan. The reason to do this is to take CO2 from coal-fired power plants and keep it out of the Earth’s atmosphere for the next millennium. We are learning to use other powerful models such as ECLIPSE and GEM to model sequestration. An important part of our work is careful geologic characterization of rock fabric and heterogeneity done in conjunction with Dr. David Barnes and his students. (2) In lab and field tests, we measured improvements due to hydrophobic gravel packs, well development and increased screen open area for both wells and trenches. We identified conservative tracers that work in free product. We have also done lab studies of the behavior of LNAPLs, DNAPLs and LNAPL/DNAPL mixtures near wells. We have studied bail-down testing methods, and used them to assess the effectiveness of various well designs. (3) We tested geotextile biointrusion barriers placed on top of contaminated sediments in the lab and in a creek. The geotextiles prevented sediment movement and were ~94% successful in preventing movement of benthic organisms and plants into and out of the contaminated sediments, thus disrupting contaminant movement up the food chain. We also showed that certain chemical oxidants, ozone and a proprietary blend of peroxides using Fenton's chemistry, were effective in the lab in rapidly degrading PCBs adsorbed to fine sediments. (4) We are interested in the application and improvement of slug tests. We are investigating flaws in the Bouwer and Rice slug test analysis method by doing multi-well slug tests at a field test site.
