An existing model (Semprini and McCarty, 1991; 1992) of in-situ bioremediation using methanotrophic bacteria for degradation of volatile organic compounds was modified to simulate use of a recirculation well. Simulations were performed to identify the best method of promoting and maintaining degradation of the target contaminant, vinyl chloride (VC). Operating parameters, such as the delivery schedule and quantity of oxygen and methane, were perturbed to identify optimal design values.
