Toxic organic contaminants may enter the subsurface as slightly soluble and volatile
nonaqueous phase liquids (NAPLs) or as dissolved solutes resulting in contaminant plumes …

Reactive chemical transport plays a key role in geological media across scales, from pore
scale to aquifer scale. Systems can be altered by changes in solution chemistry and a wide …

Groundwater transport models that accurately describe spreading of nonreactive solutes in
an aquifer can poorly predict concentrations of reactive solutes. The dispersive term in the …

The objectives of this work were to determine if a pore-scale model could accurately capture
the physical and chemical processes that control transverse mixing and reaction in …

Transport of multicomponent electrolyte solutions in saturated porous media is affected by
the electrostatic interactions between charged species. Such Coulombic interactions couple …

The representation of multispecies chemical transformations into models for porous media
flow and transport is investigated. Since the rate of transformation is dependent on the actual …

In this study, we performed multitracer laboratory bench-scale experiments and pore-scale
simulations in different homogeneous saturated porous media (ie, different grain sizes) with …

We use a particle-tracking method to simulate several one-dimensional bimolecular reactive
transport experiments. In our numerical scheme, the reactants are represented by particles …

Darcy-scale description of multicomponent reactive transport can significantly over-predict
the extent of mixing-controlled reactions. Here we present a systematic pore-and Darcy …

This pore-scale modeling study in saturated porous media shows that compound-specific
effects are important not only at steady-state and for the lateral displacement of solutes with …
