Rehabilitation of the Kerosene Damage at the Former NATO Airfield Lahr, Germany

Rehabilitation of the Kerosene Damage at the Former NATO Airfield Lahr, Germany
Before planning the rehabilitation of the large-scale kerosene damage in the near-surface groundwater of the Upper Rhine Rift near Lahr, the area was explored by means of horizontal groundwater sampling (DirectPush), pumping tests and drillings. Rehabilitation was carried out by replacing the soil in the phase saturated zone and by subsequent biological in-situ rehabilitation of the overall rehabilitation area. The section where the buildings of the airfield fire brigade are located was enclosed with a sheet pile wall. The rehabilitation measures were carried out while the airfield was in operation.
