ABSTRACT:
A process and apparatus is disclosed for removing volatile organic contaminants from vadose soil areas. Air is drawn through recovery probes positioned in the soil area being monitored. At intervals a blower is activated to draw gaseous vapors from the contaminated soil area above the underground water level. These gases are gathered within a water separator tank where gases and accidentally gathered liquids are separated. The gases are then passed through a filtration device for cleaning thereof. The device includes a water purifying system for dry cleaning contact water known to be contaminated. An external reservoir is provided for receiving of the contact water and for movement of the contact water into the water separator tank as desired. The level of water within the tank is constantly monitored. An aspiration means may be activated within the water separator tank to bubble through the contaminated liquid for stripping organic contaminants therefrom. Flow of fluid into the tank and activation of the aspiration means.
