Description:
In situ corrective action technologies are being proposed and installed at an increasing number of underground storage tank (LIST) sites contaminated with petroleum products in saturated and unsaturated zones. It is often difficult to accurately assess the performance of these systems for remediating soils and groundwater. Because of the complex subsurface characteristics encountered at leaking LIST sites, a series of tests/tools are needed for evaluating the appropriate application and remediation performance of these corrective action technologies. In response to this need, the U.S. Environmental Protection Agency (EPA) Office of Research and Development (ORD) National Risk Management Research Laboratory(NRMRL) has provided technical support to EPA Regions for evaluating in situ corrective action technologies. This report presents a series of test procedures that were developed for evaluating intrinsic biodegradation, bioventing, soil vapor extraction (SVE), and in situ air sparging (IAS). These procedures present diagnostic tools that are designed to assist in assessing remediation performance. Most of the discussions focus on evaluating systems designed for petroleum hydrocarbon contamination; however, these procedures can also be used to evaluate remediation performance of in situ technologies used to address a wide range of contaminants.
