In-situ bioremediation is a promising technology to restore groundwater and soil contaminated with organic pollutants because of its cost effectiveness and its potential capability of completely destroying the harmful compounds. Current methods include direct numerical simulations on three-dimensional problems; analysis and asymptotic methods on one dimensional systems, which are used to confirm detailed numerical results and consolidate our understanding. More effort is needed to bridge the gap between numerical and analytical results.
The speakers will present numerical simulation and mathematical analysis of traveling fronts arising in pollutant removel processes where a sorbing pollutant is degraded by indigenous bacteria stimulated by the injection of a limiting nonsorbing nutrient; numerical solute transport code for evaluating natural bioremediation, petroleum hydrocarbon spills, and chlorinated solvent plumes in groundwater; and simulations of coupled electron acceptor-based biodegradation and multiple hydrocarbon compound transport.
