Book Description
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.

Book Description
Surfactant-enhanced aquifer remediation is an emerging technology for aquifers contaminated with nonaqueous phase liquids (NAPLs). A two-dimensional micromodel and image capture system were applied to observe NAPL mobilization and solubilization phenomena. In each experiment, a common residual NAPL field was established, followed by a series of mobilization and solubilization experiments. Mobilization floods included pure water floods with variable flow rates and surfactant floods with variations in surfactant formulations. At relatively low capillary numbers (N{sub ca}

Book Description
Contamination in the vadose zone by light non-aqueous phase liquids (LNAPLs) is a widespread occurrence. Efficient remediation of soil and groundwater contaminated with LNAPL is of paramount concern to the environmental engineers. A numerical modeling study of surfactant enhanced aquifer remediation (SEAR) by promoting mobilization of LNAPL was conducted to simulate recovery of trapped residual LNAPL as free product. UTCHEM, the University of Texas Chemical flooding simulator, was successfully used to model various steps involved in SEAR: initial oil spill, primary pumping, and secondary pumping. Two different methods of surfactant application during secondary pumping to enhance mobilization of were modeled: infiltration from soil surface for vadose zone treatment, and injection at subsurface for capillary fringe treatment. Subsequent evaluation of hydraulic controls to improve oil removal efficiency resulted in 98% free product recovery. The promising result demonstrates the viability of an alternative SEAR approach that promotes mobilization as dominant mechanism.
