CMA Field Trials Phase I – Virtual Intercomparison of Monitoring Strategies
by B. M. Gawlik, L. Galbiati, J. Zaldivar, G. Bidoglio

2. Context and Background
WATER FRAMEWORK DIRECTIVE 2000/60/EC;
Expert Group on Analysis and Monitoring of Priority Substances to the Water Framework Directive Expert Advisory Forum on Priority Substances and Pollution Control;
Implementing Directive 2000/60/EC concerning minimum performance criteria for chemical monitoring methods and the quality of analytical results (in preparation);
CMA (Surface and Marine Waters, Groundwater)

3. The idea of Phase I
to compare different possible monitoring strategies used by Member States and identified in the CMA guidance document.
to evaluate the effectiveness and cost-benefit of the different monitoring strategies as proposed by the partners in the exercise (CMA/PRB volunteers).
to assess expectable variability of results caused by the monitoring strategy.
 Use simulated “virtual” data pool based on real data

4. BURANA-PO DI VOLANO and SACCA DI GORO:
Particularly important because:
Intensively cultivated,
The nutrients applied within the watershed quickly move from the basin to the coastal zone,
The Sacca di Goro lagoon is of a great importance both for ecological and economical reasons,
This watershed allows the evaluation and application of tool for the Integrated River Basin Management Plan.

5. Burana-Po di Volano (BP-V) watershed is covering an area of around 3000 km2.
It is a complex system, especially for what concerning the river network
Artificial channels
Water is moved using pumps
Direction of water in many channels is opposite respect with to the slope.

6. Landuse and management practices:

7. Tasks of Phase I Propose a monitoring network:
Geo-graphical co-ordinates of stations;
Frequency of sampling (1 year):
Sample type;
Technical information on proposed methods;
29 Polar compounds of which 7 priority chemicals.
