||A spill of gasoline occurred at an automobile service station in 1986. Oily phase residue in the subsurface has continued for the past eight years to release water soluble fuel hydrocarbons into the aquifer. Three points to coincide with direction of ground-water flow were selected in the plume for water quality assessments. Aerobic respiration and methanogenesis accounted for most biodegradation obtained. Assimilation capacities of dissolved oxygen, ferrous iron, and methane distributions when compared to BTEX concentrations showed that the ground water has sufficient capacity to degrade all dissolved BTEX before the plume moves beyond 250 meters downgradient. Evidence obtained from loss of contaminants, geochemistry, and microbial breakdown chemicals showed that intrinsic bioremediation technology would be a viable option to restore the site.
