Bioremediation of an aquifer, through the injection of labile carbon and subsequent induced denitrification, is one method of effecting a cleanup of nitrate-polluted groundwater. A one-dimensional computer model that incorporates a detailed description of nitrate biodegradation kinetics has been developed. The program is a first step towards a final model that will enable the transport and fate of a groundwater nitrate plume and the effect of aquifer bioremediation strategies to be usefully predicted. The model considers three microbially mediated reactions involving nitrate (nitrification, deoxygenation and denitrification); the transport and reactions of ammonium, nitrate, oxygen and ethanol; and the growth of nitrifying and denitrifying bacteria. Model simulations of two separate laboratory soil column denitrification experiments were able to reproduce the observed transient concentration distributions of nitrate and ethanol. Some considerations for applying a bioremediation model to the field are briefly mentioned.
