Microbial metabolism has the potential to alter the solubility of a broad range of priority
radionuclides, including uranium, other actinides and fission products. Of notable interest …

Abstract Models test our understanding of processes and can reach beyond the spatial and
temporal scales of measurements. Multi-component Reactive Transport Models (RTMs) …

A general description of the mathematical and numerical formulations used in modern
numerical reactive transport codes relevant for subsurface environmental simulations is …

Understanding concentration‐discharge (C‐Q) relationships are essential for predicting
chemical weathering and biogeochemical cycling under changing climate and …

The scale‐dependence of geochemical reaction rates hinders their use in continuum scale
models intended for the interpretation and prediction of chemical fate and transport in …

Lateral carbon flux through river networks is an important and poorly understood component
of the global carbon budget. This work investigates how temperature and hydrology control …

Our limited understanding of mineral reactive surface area contributes to significant
uncertainties in quantitative simulations of reactive chemical transport in subsurface …

Field biostimulation experiments at the US Department of Energy's Integrated Field
Research Challenge (IFRC) site in Rifle, Colorado, have demonstrated that uranium …

Redox transitions of uranium [from U (VI) to U (IV)] in low-temperature sediments govern the
mobility of uranium in the environment and the accumulation of uranium in ore bodies, and …

We use 3‐D high‐resolution reactive transport modeling to investigate whether the spatial
distribution of organic‐carbon‐rich and chemically reduced sediments located in the riparian …
