Complete and quantitative, NAPL Removal: Surfactants, Foams, and Microemulsions, belongs to a ten-monograph series that records the results of the Department of Defense/Advanced Applied Technology Demonstration Facility environmental technology demonstrations. It presents the outcome of field demonstrations of innovative in situ remediation technologies. In situ surfactant and cosolvent flushing for nonaqueous phase liquids constitutes a technique with the potential to reduce the mass of NAPL - a continuing source of groundwater contamination. This monograph details two technologies - surfactant/foam and single-phase microemulsion - selected for their potential to address the needed breakthroughs. Copiously illustrated with figures and tables, NAPL Removal: Surfactants, Foams, and Microemulsions takes you through the entire field demonstration step-by-step. It describes the development of the processes, analyzes the costs, discusses design issues, and covers performance and potential application.

A $19.3 million Department of Defense grant to Rice University funds the Advanced Applied Technology Demonstration Facility (AATDF). One of the project goals is the development of reduction strategies for nonaqueous phase liquids (NAPLs) in the subsurface. Surfactants and Cosolvents for NAPL Remediation records the results of AATDF research. The manual is a guide to the practical application of surfactants/cosolvent for in situ remediation. It is targeted to decision makers and anyone concerned with the design or implementation of these technologies. The book discusses the situational viability of surfactants/cosolvents , the possible results, design, and operation. It includes case studies, step-by-step guidance, and project cost work sheets. The successful results of the AATDF research, as documented Surfactants and Cosolvents for NAPL Remediation, are an invaluable contribution to the future of subsurface remediation. Without source NAPL reduction, the alternative is decades of plume management through pump-and-treat.

The Role of Colloidal Systems in Environmental Protection describes the importance of colloids in many applications that contribute to environmental protection, including drinking water and wastewater treatment, heavy metal remediation, treatment of radioactive materials, corrosion, and energy conversion. Knowledge of the physical and chemical composition of colloids is important to understand and accurately model the relevant processes. The book familiarizes the reader with the technological features of the application of colloids in environmental protection, and provides chemical engineers, researchers, and scientists in academic and corporate communities with the latest developments in this field.

The purpose of this book is to help engineers and scientists better understand dense nonaqueous phase liquid (DNAPL) contamination of groundwater and the methods and technology used for characterization and remediation. Remediation of DNAPL source zones is very difficult and controversial and must be based on state-of-the-art knowledge of the behavior (transport and fate) of nonaqueous phase liquids in the subsurface and site specific geology, chemistry and hydrology. This volume is focused on the characterization and remediation of nonaqueous phase chlorinated solvents and it is hoped that mid-level engineers and scientists will find this book helpful in understanding the current state-of-practice of DNAPL source zone management and remediation.
