Well having means for expelling easy volatile impurities form underground water

Abstract

Abstract In a well for expelling highly volatile impurities from groundwater, wherein the expulsion of the impurities is effected by generating a vacuum in the well shaft (10) taken down as far as the region of the contaminated groundwater and by introducing fresh air into the well shaft (10) below the water level (20), the well shaft (10) is closed at its upper end by a pressure-receiving space (25) for gases where the groundwater is under a positive pressure (P1). The pressure-receiving space (25) allows the fresh air supplied to be compressed to a pressure which compensates the pressure of the groundwater. In addition, the vacuum generator (16) is located in this pressure-receiving space (25). <IMAGE>
