Bioventing

Bioventing stimulates the natural in situ biodegradation of degradable contaminants in the unsaturated zone (above the water table). Air is supplied in situ at low flow rates to oxygen deprived soil microorganisms therefore stimulating biodegradation and minimizing the volatolisation of volatile organics into the atmosphere. Air is removed through tangential boreholes to off-gas treatment prior to being released into the atmosphere. Bioventing has been successfully used to remediate soils contaminated by petroleum hydrocarbons, nonchlorinated solvents, some pesticides and other organic chemicals. Soil stratification and structure is fundamental due to their effects on where vapors will flow in the soil matrix.
