At least 20'000 litres of heating oil had been spilled into the soil and into the ground water. At another spot the ground water had been substantially contaminated with phenol like substances. Thanks to the pile planking, which had been installed around the plot at the beginning of the building operations, remediation measures could be taken without further delay. Firstly, a waste water treatment plant was installed on site, which was able to eliminate the heating oil, which had partially emulsified in the water, as well as the phenol like substances. In a second step the ground water level was lowered by means of a ground water pump. The contaminated soil was subsequently excavated to a depth of 6 to 7 meters. Altogether, 10'000 m3 of contaminated water could be purified by means of this method. 2'000 tons of slightly contaminated soil was deposed in a landfill for inert substances, 11'000 tons of substantially contaminated soil was sent by train to Eberhard Recycling AG in Rümlang (Canton of Zurich) to be treated in a soil washing bay.
