Abstract
An arrangement drives volatile impurities from ground water and ground through which it flows by producing a negative pressure in a well shaft extending to a region of a contaminated ground water by supplying a gas in an air chamber arranged above a water level in the well shaft. The arrangement includes partitions separating a well shaft region with a water permeable shaft wall for water suction from the ground and a well shaft region for resupply of the water into the ground. The partitions are formed as a pipe. A suction pump is arranged in the water suction region of the shaft and has an outlet, and a closed water receiving chamber is arranged underneath a nozzle body. The outlet of the suction pipe is connected with the water receiving chamber.
