Performance of selected in situ soil decontamination technologies: An Air Force perspective

Every year, the U.S. Air Force stores and transfers three billion gallons of JP‐4 jet fuel. Unfortunately, not every gallon of fuel has been consumed in flight. Fuel spills account for nearly half of the chemically contaminated sites on Air Force installations and that percentage is growing as underground storage systems are more closely inspected. The Air Force Engineering and Services Laboratory is responsible for developing and testing new and more cost effective technologies capable of cleaning up fuel spills in a variety of soil and groundwater conditions. Special emphasis has been placed on soil decontamination because our sampling data has confirmed that the majority of spilled fuel is adsorbed or occluded in the soil above the water table.
