The first phase of this dossier consists of carrying out a legal-technical study in connection with the remediation of the water table (PIAC). To carry out this study, it is necessary to update the data on the overall state of the water table. This contract concerns the taking of ninety-ten groundwater samples for chemical analysis, divided into two measurement campaigns, and the performance of thirty tests to characterize hydrodynamic parameters.
