Operations and Maintenance Manual for Pilot-Scale Bioventing System at the Closed Waste POL Pit, SWMU 14, Fort Rucker, Alabama
Abstract
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 Fort Rucker, Alabama. 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. Parsons Engineering Science, Inc. (Parsons ES) has installed an air injection bioventing system consisting of an air injection blower, two vent wells (VWs), four soil gas monitoring points (MPs), and associated piping at the site.
