About This Item
Strategies for Charac terizing Subsurface Releases of Gasoline Containing MTBE Applies the principles of risk - informed decision making to the evaluation of methyl tertiary - butyl ether (MTBE) - affect ed sites by adding exposure and risk considerations to the traditional co mponents of the co rrective action process. The risk factors at a given si te are evaluated through a “conceptual site model,” which is an inventory of all known or potential oxygenate sources, pathways, and receptors. Based on these risk factors, three levels of assessment are defined: standard, li mited, and detailed. The appropriate level of assessment is initially determined based on receptor data, which can typically be obtained from a survey of nearby wells and land uses. A subsurface investigation may then be conducted to obtain information on sources and pathways. The level of assessment can be “upgraded” or “downgraded” as warranted by the resulting source and pathway information. Includes a review of th e chemical properties and subsurface behavior of MTBE and other oxygenated fuel additives. It also provides an overview of characterizati on monitoring issues at ox ygenate release sites, as well as a detailed review of the t ools and techniques used for subsurface assessment. The expedited site asse ssment process and the use of modern direct - push tools are part icularly emphasized, si nce these approaches are especially well suited for use at MTBE - affected sites
