Laboratory and field studies have shown that it is possible to degrade most fuel components under oxidizing conditions. The spread of soluble fuel components released to ground water environments is often enhanced because ground water cannot supply oxygen at a rate equal to the demand of the dissolved fuel. This study was conducted to evaluate the feasibility of using the vadose zone, or soil above the water table, which was maintained in an oxidizing state by a control system without artificially adding oxygen to treat fuel components. The test was performed at Port Hueneme, California, in an area formerly contaminated by a fuel spill. The scope of the study was limited to evaluating the field reliability of a remotely operated infiltration gallery. The results showed that it was possible to operate the system remotely with very little intervention from a field technician. None of the problems normally associated with infiltration galleries plugging from biological growth were observed. This was likely due to the draining of the distribution lines between each water application cycle. The study was conducted for more than a year, but there was little contamination remaining in the ground water when the study was performed, and it was not possible to evaluate the chemical performance of the system.
