This book gives you tools to provide assistance in the application of surfactant- and cosolvent-based flushing technologies to subsurface remediation. Written for the field practitioners, the book covers important aspects--from design to operation--of this unique remediation technique. Topics of discussion include the following: technology description and current status; geology and contaminant distribution; surfactant/cosolvent enhanced recovery of NAPL; produced fluids and management and surfactant/cosolvent flushing; cost considerations; field project case studies; literature summary database; cost worksheets/design worksheets; surfactant cost estimates; and future research.
