The land in the estate is severely contaminated due to industrial activities in the past. In certain areas, petroleum activities caused the soil to be particularly contaminated with mineral oils and aromatic compounds. The soil remediation process for the site involves the excavation and clean-up of the contaminated soil. Biological and physicochemical treatment technologies will be used to clean up this soil.
At the site of the former railway line, the soil is contaminated with heavy metals and polycyclic aromatic hydrocarbons (PAHs). The remediation technique used for this location also involves the excavation and on-site clean-up of contaminated soil. Remediated soil and lightly contaminated soil will then be used as much as possible for elevating the site, depending on the directives issued by OVAM (the Public Waste Agency of Flanders). When the soil remediation process is complete, groundwater concentrations on the site will be re-evaluated frequently at regular intervals. Based on the results and assessments of these periodic inspections, additional measures that may be required for the remediation of the groundwater will be implemented. Any such measures, as well as a full description of the remediation techniques to be used, will be incorporated in the soil remediation project.
The soil remediation process is an integral part of the entire redevelopment project of the site. Although the remediation techniques required are not technically complex, the area to be treated is quite substantial. For this reason, the remediation process is planned for completion in 2016-2017.
