This paper discusses the effects of solute transport mechanisms on the effectiveness of biodenitrification in the subsurface environment. The only solute transport processes apparently important in the Quaternary Sands Aquifer modeled in this research were advection of both nitrate and ethanol and biodegradation of ethanol. All other transport processes including hydrodynamic dispersion, adsorption, radioactive decay, and chemical reaction appeared to be negligible.
