Operations and Maintenance Manual for the Expanded-Scale Bioventing System at Building 8200, Fort Carson, Colorado
Abstract
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.
