The objective of this research is to develop basic understanding of the effect of vibrations on phase separation of immiscible contaminants in soils saturated with Non-Aqueous Phase Liquid (NAPL) and water. Exploratory studies conducted by the principal investigator indicate that vibrations induced in a soil medium saturated with NAPL and water can successfully separate and dislodge the NAPL phase. The proposed study will include a series of laboratory tests to evaluate the vibratory phase separation of NAPL ganglia as a function of vibration frequencies. The attenuation of vibratory phase separation will be assessed Dynamic criteria will be developed for phase separation and mobilization of immiscible ganglia in Soil-NAPL-water systems.
