Flashy hydrology, flashier contaminants: redox-driven geogenic contaminant mobilization under increasing hydrologic variability

As precipitation regimes intensify and engineered recharge expands, the vadose zone faces increasingly dynamic wetting–drying cycles that generate redox oscillations and alter geogenic contaminant mobility. Oxygen depletion and microbial respiration can dissolve Fe and Mn (oxyhyd...
