An experimental investigation using an artificial aquifer was conducted on in-situ denitrification. Methanol substrate was injected into the aquifer to enable denitrifying bacterial to convert the nitrates into nitrogen. The experiment in the study provided a data base that was used to evaluate mathematical simulations of the processes involved. Numerical dispersion was found to be a critical characteristic of the numerical solution technique. Density drive and plugging of the aquifer due to biological growths were found to be important processes that need to be considered in future simulations.
