AB: Subsurface transport deals with several chemical species that react with one another. These reactions are often non-linear in nature. This study focuses on the randomness of chemical concentrations which affect the fate and transport of many contaminants in the subsurface. We study uncertainties in chemical reactions by analyzing random variability in concentration for coupled sets of chemical reactions. We formulate the multiple reaction equations as a Fokker-Planck equation and utilize numerical techniques to solve the resulting high dimensional (>3) Fokker-Planck equation, where each chemical species contributes to one dimension in the Fokker-Planck equation. This study can be used to gain insight on the sensitivities of chemical reaction rates to fluctuations in concentration in multi-component reactive transport systems.
