Decision & Management Tools for DNAPL Sites: Optimization of Chlorinated Solvent Source and Plume Remediation Considering Uncertainty
Abstract
The Department of Defense (DoD) is currently responsible for cleanup of groundwater contaminated with chlorinated solvents (chlorinated volatile organic compounds, CVOCs) at thousands of sites nationwide. Much recent research has focused on technology development for both source and plume remediation (e.g. thermal methods, chemical oxidation, surfactant/cosolvent flooding, soil vapor extraction, air sparging, pump-and-treat (PAT), enhanced in-situ biodegradation) [Reddi, 1996; Brusseau et al., 1999; Wiedemeier et al. 1999; National Research Council (NRC), 2000; Kaluarachchi, 2001; US EPA, 2004b; Mayer and Hassanizadeh, 2005; Alvarez and Illman, 2006]. Process and parameter uncertainty and the expensive cost of source and plume remediation efforts have limited our ability to make effective decisions about DNAPL site remediation alternatives. For many sites, a robust, cost-effective remediation design requires some combination of source and plume remediation while considering the uncertainties that arise from hydrological and biogeochemical properties, from the site history and conditions, and from the effects of remediation.
