Preface CHEMICAL R E L E A S E S INTO THE S U B S U R F A C E are pervasive environmental problems. Sources of chemical releases range from abandoned hazardous waste disposal sites (e.g., Superfund sites) to leaking underground storage tanks at the corner gasoline station. Remediation of these releases has proven to be a formidable challenge. Many organizations are investing significant resources into the development of innovative technologies for expediting subsurface remediation. Remediation efforts are frequently inhibited by an inability to extract contaminants from the subsurface due to the significant sorption of strongly hydrophobic chemicals (e.g., poly(chlorinated biphenyl)s) or due to the presence of separate phases of nonaqueous-phase liquids (NAPL; e.g., trichloroethylene). Surfactants may be used to enhance the solubility or to mobilize such contaminants. This approach has shown promise for significantly reducing the time and cost of remediation for sites contaminated with strongly hydrophobic or immiscible organic contaminants. This volume combines a timely review of our current understanding of surfactant-based remediation technologies with an insightful discussion of critical issues that demand future consideration as these technologies move toward full-scale implementation. Contributors include representatives of academia, industry, and the regulatory community; each brings an important perspective that might be overlooked in a less comprehensive volume. Recent research results are presented by leading experts in surfactant-based remediation technologies. The chapters in this volume range from fundamental discussions of physicochemical and biological processes affecting surfactant-based technologies to implementation and optimization issues affecting the widespread, full-scale utilization of these technologies. The last chapter summarizes a panel discussion on the general topic of the future of emerging surfactant-based remediation technologies. This book will thus be invaluable for scientists and engineers with research, teaching, consulting, and regulatory or management responsibilities for environmental remediation.
