The prevalent use of methyl tert-butyl ether (mtbe) in reformulated fuel to further reduce emissions of carbon monoxide and other smog-related air pollutants has led to its introduction into groundwater from spills and leaky underground storage tanks (baehr et al 1999 klinger et al 2002 chiu et al 2006 dong et al 2007 zhong et al 2007). Mtbe(methyl tertiary-butyl ether) is a chemical compound that is manufactured by the chemical reaction of methanol and isobutylene mtbe is produced in very large quantities (over 200,000 barrels per day in the us in 1999) and is almost exclusively used as a fuel additive in motor gasoline.
