摘要

Surfactant flushing field studies have recently been conducted at several DNAPL-contaminated sites by researchers at Surbec-ART Environmental (Norman, OK) and the University of Oklahoma. Results from two demonstrations, Alameda Point, CA (formerly Naval Air Station Alameda), and Spartan Chemical Company Superfund Site, MI, are presented herein. Representative contaminants observed at the sites were trichloroethylene and 1,1,1-trichloroethane (Alameda Point), and a complex mixed waste of methylene chloride, trichloroethylene, ketones and BTEX (Spartan Chemical). These highly successful field demonstrations are all the more impressive given the widely varying site conditions, which supports the technical viability of surfactant enhanced subsurface remediation (SESR). Thus, the use of environmental-friendly surfactants for DNAPL remediation and risk mitigation is very attractive, both economically and technologically, compared to conventional pump-and-treat systems and/or other innovative technologies.
