BIOVENTING

Bioventing is an in situ remediation technique that stimulates the biodegradation of the contaminating substances, providing oxygen to the micro-organisms normally present in the soil. Air is slowly blown into the unsaturated area of the soil, thereby supplying oxygen, which facilitates the degradation activity of the micro-organisms. This method is particularly appropriate for the degradation of petroleum-related hydrocarbons, non-chlorinated solvents, certain pesticides and other organic substances.
