Reston Biogeochemical Processes in Groundwater Laboratory
The Reston Biogeochemical Processes in Groundwater Laboratory (RBPGL) research team conducts long-term investigations on the fate and geochemical effects of organic contaminants in surface and subsurface environments. Our approach combines field observations and laboratory experiments to determine how transformations of organic contaminants impact aquifer, soil, and surface-water chemistry, targeting transformations with potential ecological and health impacts.

Microbially induced anaerobic oxidation of magnetite to maghemite in a hydrocarbon-contaminated aquifer
Arsenic in petroleum-contaminated groundwater near Bemidji, Minnesota is predicted to persist for centuries
We used a reactive transport model to investigate the cycling of geogenic arsenic (As) in a petroleum-contaminated aquifer. We simulated As mobilization and sequestration using surface complexation reactions with Fe(OH)3 during petroleum biodegradation coupled with Fe-reduction. Model results predict that dissolved As in the plume will exceed the U.S. and EU 10 µg/L drinking water standard for ~40
