Abstract

This paper describes a novel bioremediation process for the treatment of oil spills on land. The method was developed specifically to deal with long term oil contamination where the volatile fractions have evaporated leaving the more recalcitrant fractions. A model system of sand and Kuwaiti crude oil was used to test the system. A combined treatment which introduced an additional solvent component was found to enhance mobility and availability of oil, enhancing bioremediation. 1 Introduction The Gulf War in Kuwait has resulted in one of the largest man made environmental disasters, and almost certainly the greatest acute contamination of land and water with oil, in history. A total of 788 wells were sabotaged by the Iraqi army on their retreat, of which 613 were set alight and 76 left to
