摘要：

Aerobic bioremediation of jet fuel in contaminated soil in an unsaturated vadose zone at Hill Air Force Base, Utah, was stimulated by soil venting. In situ respiration studies conducted at the contaminated site revealed that microbial respiration was occurring as a result of oxygen introduced by the venting process. Stable isotopic ratios (C-13/C-12) in soil gas were measured to confirm a biogenic source of carbon during venting of the contaminated soil. Although volatilization was the primary mechanism of removal, from 15 to 25% of the jet fuel was biodegraded in situ, making soil venting a promising approach for enhancing the aerobic remediation of contaminated vadose zones.
