Abstract
An arrangement for driving out of volatile impurities from ground water and a ground region through which the ground water flows comprises a well shaft extending to a region with contaminated ground water and having at least partially water-permeable shaft walls, a unit for supplying fresh air under a ground water level into the well shaft, and at least one vibration generator which produces mechanical vibrations with a limited energy such that the vibrations cause molecular liquid movements in capillaries of ground layers adjacent the contaminated ground water and do not destroy the capillaries.
