For use of the former German National Railway Repair Works (RAW) Tempelhof, on the part of the oil gas institute, pollutions of soil, soil air and groundwater had to be investigated. The property has been a fallow area since 1925.Previously, since 1895, there has been an entry of pollutions typical for gasworks (PAH, BTEX, cyanides, MKW and phenols). It was possible to detect soil contamination at the tar basin, at the gasometer and at the tar pit up to a depth of at least 13 m as well as groundwater contamination of the water-saturated soil up to the approximately 40 m deep groundwater stagnation.
