Abstract
This study, carried out in collaboration with SOGIN (Societa Gestione Impianti Nucleari - Nuclear Treatment Plant Management Company), is an integral part of environmental characterisation activity in the area where the EUREX treatment plant is situated, near Saluggia (North West Italy). With the aim of depicting the base conditions for the environment, which will then be used to develop decommissioning activities for the plant itself, a series of criteria have been defined in order to enable the identification of the present state of the environment, i.e. geologic, hydrogeologic and chemical structure, intrinsic and integrated vulnerability and land use. The study area is situated over an unconfined aquifer in a porous media of alluvial origin in the plain on the left bank of the Dora Baltea river. The whole area is strongly affected by human activities including industrial activities, extensive areas dedicated to agricultural use, quarries and numerous hamlets.

With the aim of depicting the base conditions for the environment, which will be used to develop decommissioning activities for the plant itself, a series of criteria have been defined in order to enable the identification of the present state of the environment, i.e. geologic, hydrogeologic and chemical structure, intrinsic and integrated vulnerability and land use
The aim of the study was to draw up as complete as possible a representation of the geologic, hydrogeological and vulnerability status of the groundwater resources associated with the site of the EUREX nuclear processing plant in Saluggia
Depth to water table, infiltration, properties of the unsaturated portion of the aquifer, type of cover, properties of the saturated portion of the aquifer, calculations of hydraulic conductivity and acclivity of the topographical surface, it was possible obtain the intrinsic vulnerability of the unconfined aquifer, using the SINTACS R5 method[1]
Summary
The aim of the study was to draw up as complete as possible a representation of the geologic, hydrogeological and vulnerability status of the groundwater resources associated with the site of the EUREX nuclear processing plant in Saluggia. This representation has enabled us to describe the present and where possible the past, vulnerability status of the resources and to outline the problems this may cause or has already caused, so as to create a technical policy tool for the overall decommissioning project
