Objective
The main objective for those involved in this research is to make available to the Community's iron and steelmaking industries innovatory techniques for the reclamation of excavated industrial soil (soils and leaching liquids).
This will entail developing treatments for the decontamination of soils and leachates polluted by heavy metals, cyanides and certain organic products (eg polycyclic aromatic hydrocarbons) from a former industrial site, with full-scale experiments on a large dump of excavated soil.
Sites on which mining and iron and steelmaking activities have been carried out in the Community are experiencing problems of soil and ground water pollution. This situation is typical of both active and disused iron and steelmaking sites.
Reclaiming these sites calls for very different types of treatment depending on existing regulations, the specific requirements laid down by the public authorities, geological and hydrological factors, the nature and extent of the pollution, current use and intended use after reclamation of the soil and ground water. Investigations of the extent of pollution, and even decontamination operations, have already begun on a number of sites in the Community.
In the context of the restructuring of the European Development Park situated at the convergence of the Belgium, Luxembourg and French borders, for example, UNIMETAL has been obliged to carry out the confinement of polluted soil on the former iron and steelmaking site at Longwy (Meurthe & Moselle) in order to site a new industry there. The decontamination of this large dump and its leachates calls for innovatory reclamation techniques which are not yet available. Owing to the moderate height of the soil heap (+/- 5 m), comparison of the various treatments in situ will be relatively straightforward.
