Operations and Maintenance Manual for Expanded Bioventing System at Buildings 2034/2035, Fairchild Air Force Base, Washington

Abstract

This Operations and Maintenance (O&M) Manual has been created as a guide for monitoring and maintaining the performance of the full-scale bioventing blower system and vent well plumbing at Fairchild Air Force Base (AFB), Washington. Record drawings of the full-scale bioventing system installed at Building 2035 have been provided to Fairchild AFB. Bioventing is the forced injection of fresh air, or withdrawal of soil gas, to enhance the supply of oxygen in subsurface soils for in situ bioremediation. A blower system is used to inject air into the soil, thereby supplying fresh atmospheric air (with approximately 20.8 percent oxygen) to contaminated soils. Once oxygen is provided to the subsurface, existing bacteria aerobically break down fuel residuals. Aerobic biodegradation is much more efficient than anaerobic biodegradation which occurs in oxygen depleted soils.
