The Hydrology and Geochemistry Research Lab has a variety of research projects in both natural and impacted systems. Our research focuses on (1) identifying the origin and transport of contaminants in surface waters and groundwaters, (2) understanding spatial and temporal variations in hydrology and geochemistry to identify anthropogenic influences on water budgets, and (3) determining the influence of critical zone soil biogeochemistry on weathering processes. The lab combines a ground-truth approach with a broad array of advanced analytical tools to address issues of environmental concern. Thus, most of our studies involve field observations of water quality and flow dynamics coupled with lab-based analyses of tracers (i.e., stable isotopes, major ions, and trace elements).
