Background The administrative district of Harburg is carrying out this demonstration project in order to clean up a site,which is contaminated by tetrachlorethylene (PCE).The contamination was caused by a former laundry,which operated there from 1956 until 1985 and used PCE for cleaning purposes. The sewage from the laundry infiltrated into the soil. Objectives The “EbeBoBo” project will demonstrate a newly developed soil-gas extraction technique to decontaminate very deep soils of some 40m depth, preventing the further contamination of the ground water. The PCE will be extracted from the unsaturated soil-zone by means of a vacuum. The innovation of this project consists in the application of soil-gas extraction to a very deep soil and a gas treatment technique without any impact on the atmospheric air. For this purpose technical and logistical design criteria will be elaborated. The results of the project will facilitate the design of cleanup devices suitable for similar cases across Europe where thick unsaturated zones are contaminated with volatile organic hydrocarbons (VOC). Results The beneficiary has requested a premature termination of the project. No project results were achieved.
