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.

This Operations and Maintenance (O&M) Manual has been created as a guide for monitoring and maintaining the performance of the pilot-scale bioventing blower system and vent well plumbing at Building 8200, Fort Carson, Colorado 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 soil bacteria aerobically break down fuel residuals. Aerobic biodegradation is much more efficient than anaerobic biodegradation which occurs in oxygen depleted soils.

This letter presents the results of the bioventing system monitoring performed by Parsons Engineering Science, Inc. (Parsons ES) from February to April 1998 at Building 8200, located at Fort Carson, Colorado. Oxygen influence monitoring and blower shut down occurred on 23 February 1998. In situ respiration testing was performed by Parsons ES between 23 February and 15 April 1998 to assess the extent of remediation completed during approximately 7 months of pilot-scale air injection bioventing followed by 9 months of expanded-scale bioventing. Static soil gas sampling for field and laboratory analysis was performed on 8 April 1998, 44 days following blower shut down. The purposes of this letter are to summarize site and bioventing activities to date, present the results of the 1998 system monitoring event and compare them with the results of the initial bioventing pilot test (July and August 1996) and expanded-scale system installation (April and May 1997), and to recommend future remediation activities for the site based on these findings.

In October 1992, Parsons ES (formerly Engineering-Science Inc. ES) installed a bioventing pilot test system at Site FT-O3 to remediate soils impacted by jet fuels, reclaimable mixed fuels, and other flammable wastes that were used during fire training exercises at the site. The pilot-scale system was composed of one 4-inch diameter horizontal vent well (HVW), four permanent soil vapor monitoring points (MPs) and several temporary soil MPs installed in fuel-impacted soils on the north side of the burn pit. A single 1-HP blower was used for the pilot-scale system. The pilot-scale system was operated and monitored by Parsons ES as a pilot study for one year, from November 1992 through November 1993. Following the one-year pilot study, the Base operated the pilot test blower system for another 3.5 years.

An initial bioventing pilot test was performed by Parsons Engineering Science, Inc. (Parsons ES) at Building 8200 at Fort Carson, Colorado during the period from July 15 through August 7, 1996. The proposed scope of work for this site was performed for Fort Carson, the US Army Environmental Center (USAEC), and the Air Force Center for Environmental Excellence (AFCEE) Technology Transfer Division (ERT) under AFCEE contract F41624-92-D-8036, Order 0017. The purpose of this report is to describe the results of the initial pilot test at Building 8200 and to make recommendations for extended testing and full-scale system installation to determine the long-term impact of bioventing on site contaminants. Descriptions of the history, geology, and contamination at Building 8200 are presented in the bioventing pilot test work plan (Parsons ES, 1996). The sources of vadose zone soil contamination at this site were four former 20,000-gallon underground storage tanks (USTs) that were used to store gasoline and diesel fuel Rust Environmental & Infrastructure (RUST), 1994. The tanks were removed by Parker Excavating during November 1996 (Cloonan, 1996a). Full-scale bioventing system installation is expected to occur in early 1997.

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).
