- 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 and their microbial consortium when 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 or subaerial sediments. These probes induce contaminant fluorescence by excitation with either laser or x-ray irradiation.
- Use of portable x-ray spectrometers to directly detect lead (Pb) levels in the edible portion of vegetables. This is a much easier and more direct way to determine if vegetables grown in urban settings are safe to eat than estimating Pb uptake solely from soil measurements.
