ABSTRACT:
A process and apparatus for the in-situ decontamination of ground water polluted with heavy metal ions, wherein a ground water peak (26) is built up by means of gasification (24) in a well pipe (10), and a current is produced in the ground water. The current is conducted through a siphon (18, 44, 46) furnished with an ion exchanger (50), and the heavy metal ions from the water current migrate to the ion exchanger by the application of electrical voltage (48).
