Cleanup Technologies

Between 1988 and 2017, 538,193 confirmed underground storage tank leaks were reported to the EPA, including those reported to states. It is important that cost-effective cleanup solutions be chosen, and that the technology be appropriate for the site and spill conditions. The list below summarizes alternatives to pump-and-treat remediation, which can be expensive yet ineffective in many geologic settings. For more in-depth information on cleanup technologies, see the EPA UST Special Interest Group’s document collection.

This information comes from How to Evaluate Cleanup Technologies for Underground Storage Tank Sites, EPA510B95006, United States Environmental Protection Agency, May 1995, and from Workbook, Part I, First Annual Conference on Hydrocarbon Contaminated Soils.
