Disclosed are methods for electrochemically remediating soil, clay or other media contaminated with organic pollutants using Fenton's Reagent. In the methods, anodes and cathodes are provided in wells formed in the contaminated medium. Anolyte and catholyte solutions are circulated to deliver iron ions to anodes and to deliver peroxide ions to cathodes in the medium. A potential difference is applied across the medium to cause the peroxide ions and iron ions to migrate toward each other and through the medium. The organic contaminants are destroyed in the medium in reactions with the peroxide ions and iron ions. The physicochemical condition of the electrolyte(s) is monitored and adjusted as necessary to control pH and to permit recycling of the electrolyte to the electrodes. Alternatively, peroxide ion can be generated in situ using an air depolarized cathode.
