ABSTRACT:
A method and apparatus for sustaining optimum fluid entrainment conditions in a contaminant extraction well is disclosed. More specifically, the present invention includes a central controller which communicates with a pressure detector and an aspiration control source that are connected to a contaminant extraction well. The central controller causes aspiration air to flow into or out of the extraction well based upon the vacuum level that has been measured by the pressure detector. This system enables the vacuum to be maintained at a predetermined level, and allows the well to operate as changes occur in the groundwater content of the area in which the well is operating.
