Description:
The use of surfactant and co-solvent solutions to remove non-aqueous phase liquids (NAPLs) from soils has seen significant research and development activity over the last decade. These soil flushing technologies are now entering the full-scale implementation stage of their development. Since performance assessment is critical to the acceptance of a new technology, methods for assessing the NAPL removal efficiency of soil flushing technologies have been concomitantly evaluated and developed. In this paper, several performance assessment approaches will be described and the use of these approaches during a surfactant-based soil flushing field demonstration project will be detailed.
