Abstract There has been a great deal of focus on methyl tertiary butyl ether (MTBE) over the past few years bylocal, state, and federal government, industry, public stakeholders, the environmental services market, andeducational institutions. This focus is, in large part, the result of the widespread detection of MTBE ingroundwater and surface waters across the United States. The presence of MTBE in groundwater has been attributedprimarily to the release from underground storage tank (UST) systems at gasoline service stations.MTBE's physical and chemical properties are different than other constituents of gasoline that havetraditionally been cause for concern [benzene, toluene, ethylbenzene, and xylenes (BTEX)]. Thisdifference in properties is why MTBE migrates differently in the subsurface environment and exhibits differentconstraints relative to mitigation and remediation of MTBE once it has been released to subsurface soils andgroundwater. Resource Control Corporation (RCC) has accomplished the remediation of MTBE from subsurface soil andgroundwater at multiple sites using ozone. RCC has successfully applied ozone at several sites with differentlithologies, geochemistry, and concentrations of constituents of concern. This article presents results fromseveral projects utilizing in situ chemical oxidation with ozone. On these projects MTBEconcentrations in groundwater were reduced to remedial objectives usually sooner than anticipated. © 2002Wiley Periodicals, Inc.
