Hydraulic fracturing for polluted soils recovery

The Belgium company ''Ecoterres'', specialist in soils treatment, has developed a new method for the decontamination of polluted sites. This method has allowed the recovery of some 780000 liters of fuel from the Nynas storage site in Wandre, near liege (Belgium). This short paper describes the drilling, hydraulic fracturing and pumping operations involved in this method which have allowed the complete recovery of the fuel spill. The pumping operation is still in progress to avoid a water pollution in the neighbouring Meuse river. (J.S.)
