Abstract : The overall goal of Technical Objective 2: Soil Reactivity was to assess how soil properties (e.g., soil mineralogy, natural carbon content) affect oxidant mobility and stability in the subsurface, and develop a standardized natural oxidant demand (NOD) measurement protocol. To fulfill this objective, materials from nine sites were obtained for use in this investigation and characterized with respect to physio-chemical properties and evaluated with respect to their total theoretical and experimental reductive capacity. These materials were then used in batch and column experiments with three oxidants, permanganate, Fenton's reagent and persulfate to evaluate the fundamental chemical properties affecting oxidant consumption, the maximum NOD of aquifer materials, kinetic behaviour of permanganate with various aquifer materials and oxidant transport.
