Bioventing
Bioventing is the process of aerating soils to stimulate in situ biological activity and promote bioremediation. Bioventing typically is applied in situ to the vadose zone (i.e., unsaturated soils) by injecting oxygen in the form of air. Bioventing systems are designed to maximize biodegradation while minimizing volatilization. The technology is applicable to any chemical that can be aerobically biodegraded; however, to date has been implemented primarily at petroleum-contaminated sites.
