This document is a product of the bioventing research and development efforts sponsored by the U.S. Air Force Armstrong Laboratory, the Bioventing Initiative sponsored by the U.S. Air Force Center for Environmental Excellence (AFCEE) Technology Transfer Division, and the Bioremediation Field Initiative sponsored by the U.S. Environmental Protection Agency (U.S. EPA). The Armstrong Laboratory Environics Directorate (AL/EQ), an element of the Air Force Human Systems Center, began its research and development program in bioventing in 1988 with a study at Hill Air Force Base (AFB), Utah. Follow-on efforts included field research studies at Tyndall AFB, Florida, Eielson AFB, Alaska, and F.E. Warren AFB, Wyoming, to monitor and optimize process variables. Results from these research efforts led to the Bioventing Initiative and are discussed in this document.

Soil bioventing is one of the most popular modern techniques for removing contaminants from soil. It has recently emerged as one of the most cost-effective and efficient technologies available for vadose zone remediation of petroleum-contaminated sites. This book explains in practical terms how to carry out a bioventing program. It is an interdisciplinary treatment of the subject, covering everything from basic physical and chemical properties of soils to site evaluation, project design, and post-bioventing monitoring. The wide breadth of coverage makes Soil Bioventing useful to a large audience, including consulting firms, students, contractors, environmental managers, and anyone who is responsible for supervision of soil cleanup for regulatory reasons.

This Operations and Maintenance Manual has been created as a guide for monitoring and maintaining the performance of the bioventing blower and vent well plumbing at the Fire Training Area (Site FC-2) located at Kelly Air Force Base (AFB). Bioventing is the forced injection of fresh air, or withdrawal of soil gas, to enhance the supply of oxygen for in situ bioremediation. At Site FC-2, one pressure air injection blower unit 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 soils when the soils are oxygen depleted. Parsons Engineering Science (Parsons ES) has installed an air injection vent well system consisting of six vent wells at Site FC-2. The blower was started on January 26, 1996 and injected flow rates were adjusted so that the injection rates at each vent well are relatively uniform (9.2 to 12.3 cubic feet per minute).

This operations and maintenance (O & M) manual has been created as a guide for monitoring and maintaining the performance of the expanded-scale bioventing blower system at Building 8200, Fort Carson, Colorado. Record drawings for the expanded-scale bioventing system, installed at Building 8200 in May 1997 in accordance with the site remedial action plan, are provided in Appendix A of this O & M manual. At this site, bioventing is the forced injection of fresh air to enhance the supply of oxygen to native bacteria in subsurface soils for in situ bioremediation of fuel hydrocarbons. A blower system is used to inject air into the soil, thereby supplying atmospheric air (with approximately 20.8 percent oxygen) to contaminated soils. Once oxygen is provided to the subsurface, indigenous aerobic bacteria biodegrade fuel residuals. Aerobic biodegradation of fuel compounds in soil is much more efficient than anaerobic biodegradation, which occurs in oxygen-depleted soils.
