Military Airport Gatow – Berlin
The site was used as a military airport from 1930 to 1995. In 1988 a contamination over an area of 4.000m² and with an average of 60cm of floating material originating from two underground kerosene tanks was discovered. Since future planning zoned the area as residential, it was decided that the soil and groundwater would be remediated using soil-gas ventilation, soil exchange and groundwater remediation. In July 1999 the contract was awarded to the JV INTERGEO Radeberg/TEERBAU Spreehagen.
