Post-Remediation Performance Assessment at a Petroleum Impacted Site
Abstract
Many successful demonstrations have been conducted on light non-aqueous phase liquid (LNAPL) removal and plume treatment technologies. Technologies such as bioventing, dual-phase extraction (DPE), air sparging and monitored natural attenuation (MNA) were demonstrated successfully to show that LNAPL could be removed and benzene, toluene, ethylbenzene, and xylenes (BTEX) plume migration could be controlled. The expectation was that, unlike chlorinated solvents, petroleum sites could be closed after a reasonable period of time. However, in the longer term, many of these sites are still struggling to remove enough free product to meet U.S. Environmental Protection Agency (EPA) and state requirements of source control (product mobility) as well as plume treatment and are continuing to face long-term management challenges. The primary objective of this project is to help the Department of Defense (DoD) and others make a stronger case for closure of legacy petroleum sites, and expand users' knowledge of high-impact methods that can better reveal that actual risk associated with LNAPL presence and therefore help stakeholders make more informed remediation decisions.
