Fractured rocks are ubiquitous in the near-surface region of Earth and play a critical role in both natural and engineered systems, including water supply, geologic sequestration of CO 2 , and the long term storage of spent nuclear fuel (Berkowitz, 2002). The heterogeneous geologic structure within these systems, often spanning multiple orders of magnitude (Bonnet et al., 2001), leads to spatial variability of advective and diffusion-dominated flow regions, which in turn leads to complex reactive transport behaviors (
