Popis: Vulnerability was assessed on the basis of several related intrinsic properties represented by the capacity of protection of the non saturated zone and the susceptibility of the aquifers to qualitative degradation, as the available information on the hydrogeological configuration was not sufficient to perform a classical vulnerability assessment. Attention has been focused on aquifers of significant importance in the area which are used as a source of both public and domestic drinking water. Priority was given to public managers in selecting the withdrawal points as they guaranteed conditions of access and maintenance and represented significant utilization environments. This working method led to greater priority being given to the quality aspects of the resource than to the quantitative aspects. The test activities involved making a census of 121 withdrawal points including wells and springs subjected to field measures and the taking of water samples for laboratory analysis. A set of 50 of these were selected as an "executive network" for a second sampling using an empirical procedure that qualitatively combined significant aspects of vulnerability and of the state of aquifer contamination. The concluding phase of the research involved the development of an original GIS procedure in which a quantitative treatment is given of the specific aspects of vulnerability and the withdrawal point characteristics. The use of this procedure allowed a second set of withdrawal points to be identified, denoted as the "optimized network", which partially coincides with the first one. The procedure represents a significant innovation as it allows the network to be optimized with reference to the specific objective of the monitoring in a more rapid and objective fashion than when using the conventionally performed selections using empirical procedures.
