Beschreibung
Zusammenfassung:	A method and system for removing contaminants for the phreatic zone, also known as the saturation zone, or groundwater. The technique involves gas sparging and oxidation while increasing the surface area for mass transfer by the placing of packing balls into the eductor tube. The system is comprised of a means for supplying gas/ozone mixture to the lower extent of a well which induces a flow of groundwater and gas bubbles up the well. The system contains a conduit within the well, which extends below the water table The conduit has a lower fluid-permeable section which is located below the water table and an upper fluid-permeable section which is adjacent the water table.
