Engineering and Monitoring of a BIOVENTING Remediation System
Abstract
Bioventing is a cost efficient in-situ technique for the removal of low or non volatile organic pollutants (Diesel, heating fuel, lubricants, etc.) from the unsaturated soil zone. Microbial degradation is stimulated by increasing the oxygen concentration in the subsurface (extraction of soil gas, introduction of ambient air). Degradable and available contaminants (hydrocarbons) are removed from the soil by microbial metabolism finally resulting in carbon dioxide and water. Within this project, the limits for a successful application of the Bioventing Technique were investigated. Besides the determination of physical-chemical requirements (permeability, water saturation, alkalinity, nutrients), site investigations (soil gas survey, in-situ respiration test) were accomplished to assess the potential for biodegradation and to monitor remediation success.
