  • Apparatus and process for removing volatile contaminants from below ground level
    Patent number: 4945988
    Abstract: A process for removing and disposing of or neutralizing volatile contaminants existing in the vadose zone of earth and also in a below ground aquifer. The process includes the injection of substantially oxygen free air into the aquifer to retard the formation of aerobic bacteria and injection of oxygen rich air into the vadose zone to stimulate bacterial growth which aids contaminant recovery. Volatilized contaminants are pulled out of the soil through withdrawal wells which terminate in the vadose zone.
