A denitrifying consortium capable of transforming carbon tetrachloride (CCl[sub 4]) was cultured from an aquifer soil sample from the US Department of Energy's Hanford Site in southeastern Washington State. A mathematical description of the kinetics of CCl[sub 4] destruction by this microbial consortium is presented, and its predictions are compared to experimental data. The model successfully predicted the concentrations of acetate, nitrate, nitrite, biomass, and CCl[sub 4] for all 12 experiments (a total of 60 concentration-vs.-time data sets). In addition, no statistically significant interactions exist between parameter values and individual test conditions. The ability of the model to predict the results of a treatability test for CCl[sub 4] degradation in Hanford groundwater, without adjusting any model parameters, is discussed.
