Remediation Of MTBE Contaminated Soil And Groundwater
Methyl tertiary-butyl ether (MTBE) is a fuel additive made, in part, from natural gas. Since 1979, it has been used in the United States as an octane enhancing replacement for lead, primarily in midand high-grade gasoline at concentrations as high as 8 percent (by volume). Since the mid-1980s, it has been widely used throughout the country for this purpose. It is also used as a fuel oxygenate at higher concentrations (11 to 15 percent by volume) as part of two U.S. EPA programs to reduce ozone and carbon monoxide levels in the most polluted areas of the country.
