  Physical and chemical heterogeneities have a large impact on reactive
transport in porous media. Examples of heterogeneous attributes affecting
reactive mass transport are the hydraulic conductivity (K), and the equilibrium
sorption distribution coefficient (Kd). This paper uses the Deng et al. (2013)
conceptual model for multimodal reactive mineral facies and a Lagrangian-based
stochastic theory in order to analyze the reactive solute dispersion in
three-dimensional anisotropic heterogeneous porous media with hierarchical
organization of reactive minerals. An example based on real field data is used
to illustrate the time evolution trends of reactive solute dispersion. The
results show that the correlation between the hydraulic conductivity and the
equilibrium sorption distribution coefficient does have a significant effect on
reactive solute dispersion. The anisotropy ratio does not have a significant
effect on reactive solute dispersion. Furthermore, through a sensitivity
analysis we investigate the impact of changing the mean, variance, and integral
scale of K and Kd on reactive solute dispersion.
