Description: Groundwater contamination due to leaky underground fuel tanks is a common problem at civilian and military      sites worldwide. The U.S. EPA estimates that 35% of the U.S.'s underground motor fuel tanks are leaking (I),      which corresponds to approximately 2 million tanks, and approximately 40% have resulted in groundwater      contamination (2). Benzene, toluene, ethylbenzene, and xylenes (known collectively as BTEX) are      water-soluble fuel constituents that comprise 50 wt % of the water-soluble fraction of gasoline (3). The      occurrence of BTEX in groundwater is of concern due to the hazards that they pose toward human health. For      example, benzene is a confirmed carcinogen and toluene, while it is less toxic than benzene, depresses the      central nervous system. The EPA water quality criterion for benzene and toluene in drinking water is 0.005      mg/L and 14.3 mg/L, respectively (4)
