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.
As an alternative to traditional pump-and-treat or soil excavation, in-situ chemical oxidation (ISCO) is an emerging remediation technology that delivers oxidants (a.k.a. oxidizers) into the subsurface, which chemically react with the target contaminant via oxidation-reduction ("redox"). These redox reactions convert the contaminants into carbon dioxide, water, and other products, ultimately reducing concentrations of the target contaminant in soil and groundwater.
Treatment systems that use ISCO rely upon wells spaced at specific intervals to inject the oxidant, extract vapor or groundwater, and monitor various performance parameters. Despite the potential for its success, one must carefully consider both the site conditions and contaminant properties before implementing ISCO.
This course is intended for environmental engineers who wish to expand their knowledge of alternative methods of site remediation.
