Dynamics of element-mineral interactions
Interactions with minerals often control the mobility of contaminant and nutrient elements in terrestrial waters. Our research within this theme examines how changing environmental conditions impact element-mineral associations and, therefore, element mobility and bioavailability. Current projects are focused on understanding how V and Mo mobility are influenced by redox transitions and oscillations in the presence of Fe(III) (oxyhydr)oxides. Our results are providing new insight into biogeochemical controls on metal mobility with regional to global implications.

Geochemical processes in mining landscapes
Mine wastes often have negative impacts on water chemistry in mine reclamation landscapes. This research examines the geochemical co-evolution of mine wastes and associated waters at active, reclaimed, and abandoned mines. Relationships between hydrogeological conditions and and biogeochemical processes are being examined across scales to better understand the landscape geochemistry of these sites. Results support development of mine closure strategies aimed at mitigating long-term contaminant fluxes within reclaimed mining environments.
