[en] Accidental release of light non aqueous phase liquids (LNAPLs, such as gasoline) into the subsurface can be a significant health and environmental concern. LNAPLs mostly reside in the zone of water table fluctuation and therefore, pose hazards in air (vapour) and water phases. The recovery and removal of LNAPLs through appropriate methods is a basic step in remediation of contaminated sites. Any technical approach such as pilot and field-scale trials to determine appropriate recovery methods for a particular site and condition may be expensive and time consuming. In addition, the long-term consequence and the endpoint of the recovery is not easily predictable. Simulation provide an avenue to assess this for a range of remediation options. Here we simulate field pilot trials to show how a multi-phase and multi-component framework can be used to determine the effective endpoint of LNAPL remedial options. (author)
