EPA confirmed nearly 3,000 new releases from underground storage tanks (USTs) during fiscal year 2010, bringing the cumulative total to 491,572 releases since 1984. Although progress has been made in cleaning these sites, over 96,000 of them still require remedial action. (Source: Semiannual Report of UST Performance Measures, Mid Fiscal Year 2010, 3/31/2010.). These UST leaks pose a grave threat to human health and the environment by contaminating groundwater and soil.
This course is intended for environmental engineers who wish to expand their knowledge of alternative methods of groundwater treatment. The course material is extracted from Chapter 10 (May 1995), of the EPA publication EPA 510-R-04-002, How to Evaluate Alternative Cleanup Technologies for Underground Storage Tank Sites: A Guide for Corrective Action Plan Reviewers. Updated May 2004.
