Abstract
A method for reducing organic contaminants in a well initially breaks down complex organic compounds by radiation with gamma radiation. The remaining materials are subjected to oxygen radicals in the water, the oxygen radicals reacting with the materials to assist in the degradation. A carrier is formed with a plurality of containers fixed together by struts, and each container has a quantity of radioactive material to provide the radiation. Air, oxygen and or peroxide may be fed to the well to provide enough oxygen to produce the oxygen radicals, or the water may be cavitated to free the oxygen in the water. The apparatus & method may also be adapted with proper shielding for use in surface applications, such as surface water intakes (biofouling by Asiatic clams), general ground water and haz-waste treatment.
