Summary We demonstrate the effectiveness of a non-Arrhenius kinetic upscaling approach for in-situ-combustion processes, first discussed by Kovscek et al. (2013). Arrhenius reaction terms are replaced with equivalent source terms that are determined by a work flow integrating both laboratory experiments and high-fidelity numerical simulations. The new formulation alleviates both stiffness and grid dependencies of the traditional Arrhenius approach. Consequently, the computational efficiency and robustness of simulations are improved significantly. In this paper, we thoroughly investigate the performance of the non-Arrhenius upscaling method compared with Arrhenius kinetics. We investigate robustness by considering grid effects and sensitivity to heterogeneity. Performance improvements of the new kinetic upscaling approach compared with traditional Arrhenius kinetics are demonstrated through numerical experiments in one and two dimensions for both homogeneous- and heterogeneous-permeability fields.

Nitrate contamination of groundwater is a growing problem in the U.S. and throughout the world. This paper examines the potential application of in-situ bio-denitrification to reduce nitrates in groundwater to an acceptable level as well as pertinent parameters that control the process. Results from laboratory experiments designed to simulate in-situ bio-denitrification using an aquifer model are compared to results of experiments reported in the literature. The results indicate that while denitrification can be effective in reducing nitrates in contaminated groundwater, serious aquifer plugging problems can be expected. Furthermore, the avoidance of the plugging problem requires that careful management schemes be implemented during in-situ treatment The results of field-scale experiments in Europe and other areas generally confirm the efficacy of bio-denitrification. However, aquifer plugging was not reported by some of these studies or appeared to be downgraded by others. In some cases, this problem was reported as having serious ramifications on the success or failure of bio-denitrification. In addition to aquifer plugging, other problems can be expected. These include residual organics and the presence of large bacterial counts in the treated water with subsequent potential effects on the water turbidity, disinfection requirements, and public health acceptability.
