Abstract:

Fuel contamination of the subsurface environment can exist in as many as three phases. First, there will exist a soluble phase resulting from chemical components in the fuel such as benzene, toluene, and xylene dissolving into the ground water and becoming transported by it. Another is the residual phase consisting of immobile fuel contained within the pore spaces of the vadoze zone above the water table. Finally, there is a free-fuel phase that is a mobile liquid that can spread out over the water table and generally follows its flow path. It is the measurement and estimation of this phases thickness that is the main subject of this project. The objectives of this project were to compare three methods of estimating the actual free-fuel product volume in the unsaturated zone of ground water. This project was unique in that the volume estimates were meade of six actual sites where JP-4 jet fuel exists on the aquifer, rather than using laboratory conditions.
