Jet fuel-4 (JP-4), the major jet fuel used by the U.S. Air Force, is a major source of contamination for many soils and ground waters. Monoaromatic hydrocarbons are major constituents of the fuel. Because these compounds are relatively water soluble, they tend to migrate from contaminated soils into aquifers, a plume generally develops downgradient from the free product in the source area of release. Physical (dispersion, volatilization), chemical (sorption), and biological processes (microbial degradation), and the interplay of these processes control the fate and transport of the contaminants in the subsurface. Microbial degradation reactions are the most important processes in reducing the concentrations of the contaminants. Aromatic hydrocarbons are subject to degradation by aerobic and anaerobic microbial transformation processes in the subsurface. The degradation of these compounds by in situ microorganisms can serve as a primary remediation mechanism. This study evaluated the biodegradation of alkylbenzenes in a contaminated aquifer using chemical and biogeochemical markers.
