Abstract

Previous experiment was performed under abiotic condition. Steady-state abiotic experiments in the sand-tank reactor with air flowing through the reactor headspace demonstrated that oxygen supply through the water table interface into the saturated zone was enhanced when an LNAPL (dodecane) pool was present at the water table. Biotic condition was considered in this study. Biotic experiments performed after inoculating the reactor with Pseudomonas putida mt-2, which does not grow on dodecane, indicated that the enhanced oxygen supply in the presence of the LNAPL pool also enhanced biodegradation of a solute (glucose) plume passing beneath the LNAPL pool at steady-state.
