Environmental Protection Agency Groundwater Sensitivity Toolkit (GW Toolkit) Overview


The Groundwater Sensitivity Toolkit was designed to help site managers, water purveyors, and regulators evaluate the sensitivity of a groundwater resource to a potential release of compounds of concern (for instance, a fuel oxygenated by methyl tertiary butyl ether [MTBE]) at a specific site. The toolkit runs on Microsoft Excel and comes with a user's guide.
