BioVenting/BIOVAC^SM

Definition

• Utilizes the injection of oxygen and/or other nutrients for the enhancement of indigenous microorganisms for biodegradation of contaminants in soil and groundwater.
• Provides the proper environment to allow microorganisms to consume volatile, semi-volatile and non-volatile contaminants from the soil and groundwater matrix.

Application

• Typical vadose zone soil permeability range of 0.1 to 10,000 millidarcies (equivalent of 10E-6 to 10E-1 cm/s hydraulic conductivity).
• Contaminated soil and groundwater matrices containing volatile, semi-volatile and non-volatile organic compounds.
• Organic petroleum compounds, such as Stoddard Solvent, fuel oil or waste oil.

Unique Characteristics

• In situ technology minimizes site or property disturbances. Can be performed under existing buildings and structures.
• Often requires no vapor treatment system, which can significantly reduce overall remediation system costs.
• Low cost remediation option.
