Abstract:

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 mgL and 14.3 mgL, respectively 4.
