This paper reports the development and application of a three‐dimensional multi‐component reactive transport model (BGTK) to simulate a wide range of biogeochemical processes in subsurface environments. The model can handle both equilibrium and kinetically controlled reactions and is based on the well tested modular models RT3D [ Clement et al. , 1998] and PHREEQC‐2 [ Parkhurst and Appelo , 1999]. Here we describe the details of the new coupled model and demonstrate its capabilities using test problems involving microbial transport in a laboratory column and redox zonation in a contaminated aquifer.
