Abstract

An innovative in-situ remedial technology, soil vapour extraction (SVE), was simulated in the laboratory. Two types of soil, a sandy soil and an organic top soil, were packed into 1 m tall and 100 mm diameter stainless steel columns. Benzene, toluene, ethylbenzene and xylene, known collectively as BTEX, were added to the soils individually and as a mixture. Before addition to the soils, all contaminants were added to water, to achieve a concentration of 150 mg/L. The conditions simulated in this set-up were similar to those found in a gasoline contaminated soil that has undergone sufficient vapour stripping to remove the separate, non-aqueous, contaminate phase or a contaminant plume that has leached from a gasoline spill. Three flow rates, 1.5, 3.0 and 6.0 L/h were used for each of nine sets of experiments. The four BTEX components were stripped individually and as a mixture, from sandy soil using dry air. Toluene was stripped, from sandy soil using moisture-saturated air also. In the final three experiments, the organic soil contaminated individually with, benzene, toluene and xylene was stripped.
