Policy evaluation Theoretically speaking the TIZIANO groundwater monitoring system should be capable of supporting regional decision-makers at each step of the decisional path. In few words the network should support 1 Assessing the initial state of the natural system and reporting negative trends 2 Controlling the effects of environmental actions and politics 3 Alerting for undesired evolutions. The spatial extension of the monitoring network and the number of monitoring wells should be revised at each step. Step one should be performed extensively over the monitoring area and step two should focus around risk area. Step three should be suitably designed in order to be capable of capturing any warning signal at this step the position of the monitoring points the parameters to be measured and the frequency of measurement need to be carefully evaluated. The TIZIANO monitoring network performed very well the first step Assess . Unlikely we have less evaluation elements concerning the monitoring network suitability during the second phase Control . Finally concerning the third step Alert the monitoring activity have been moved and increased around area considered mostly at risk and reduced in the rest of the region. Monitoring evaluation The monitoring program does not contain an evaluation phase. This means that the second learning process described in figure 1 cannot be supported. The critical analysis of the TIZIANO groundwater monitoring system can be summarized as shown in table 3. Criteria Evaluation - Information producer information users interaction - Mainly based on scientific requirements and legislation - Degree of participation - Weak in the design phase strong during the implementation - Multi-scale monitoring - There is no analysis .
