Oil venting has been used for many years as a cost-effective, in situ treatment for volatile hydrocarbons, such as gasoline. The process involves flushing contaminated soils with air to remove the hydrocarbons. Treatment rate depends on air flow through the soils and how effectively the hydrocarbon contaminants partition into the mobile air phase. Because contaminants must volatilize and partition into air undergoing removal, fuels containing significant amounts of low-volatility hydrocarbons--such as diesel fuel, fuel oils or jet fuels--often are not targeted for remediation by soil venting. Sites having soil heterogeneities that result in uneven air permeability also can prevent effective treatment using conventional soil venting.
