Abstract
The behavior of dodecane (Light Non- Aqueous Phase Liquid - LNAPL) or trichloroethylene (Dense Non-Aqueous Phase Liquid - DNAPL) at residual saturation, subject to various freeze-thaw cycles was studied. In the LNAPL experiments, a substantial upward remobilization of LNAPL was observed with successive freeze-thaw cycles. This was attributed to the detachment of mobile LNAPL from larger ganglia during freezing and transport above or with the freezing front. Significant fragmentation of LNAPL ganglia also occurred, and subsequent formation of sub-singlet and singlet ganglia on thawing. DNAPL was migrated both in vertical and horizontal directions, where horizontal movement was more predominant due to the high capillary and gravity forces in vertical direction during upward freezing. This is an abstract of a paper presented at the 2007 Petroleum Hydrocarbons and Organic Chemicals in Ground Water: Prevention, Assessment and Remediation Conference (Houston, TX 11/5-6/2007).
