CTCN Keyword Matches:

A method and apparatus are disclosed for removing contaminants from the ground using vacuum extraction. Specifically a circuit (400) is disclosed that can control the flow of atmospheric air into a vacuum extraction well (114). By controlling the air flow into the well the air flow circuit serves to regulate the vacuum that is applied to sub-surface contaminants. This vacuum lifts the contaminated effluent from the ground so it can be subjected to further processing.
