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.

Cyclical Mobilization and Attenuation of Naturally Occurring Arsenic in an Underground Petroleum Plume

Contaminant exposure and transport from three potential reuse waters within a single watershed

Global demand for safe and sustainable water supplies necessitates a better understanding of contaminant exposures in potential reuse waters. In this study, we compared exposures and load contributions to surface water from the discharge of three reuse waters (wastewater effluent, urban stormwater, and agricultural runoff). Results document substantial and varying organic-chemical contribution to

Microbially induced anaerobic oxidation of magnetite to maghemite in a hydrocarbon-contaminated aquifer

Iron mineral transformations occurring in hydrocarbon-contaminated sites are linked to the biodegradation of the hydrocarbons. At a hydrocarbon-contaminated site near Bemidji, Minnesota, USA, measurements of magnetic susceptibility (MS) are useful for monitoring the natural attenuation of hydrocarbons related to iron cycling. However, a transient MS, previously observed at the site, remains poorly

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
