Research interests
- The overall geochemistry of the deep sandstone aquifer of the upper Midwest. The last of the Pleistocene ice advances injected a large pulse of fresh water into this aquifer, and through the use of noble gas and stable isotope data, we are unraveling the dynamics of this one-time event.
- The effects on shallow aquifers if treated effluent is used to recharge the aquifer either directly or indirectly by the use of riverbank filtration.
- The development of a suite of in-situ probes for the rapid, screening-level detection of contamination in submerged sediments. These probes induce contaminant fluorescence using laser or x-ray excitation.
