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)

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

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.

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.

Landuse and management practices:

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. E-dossier can be accessed for all on FTP: ftp://ftp.ei.jrc.it/pub/cma Assess usefulness of provided data; Missing data; Proposals for improvement; Concentrations are computed by JRC-IES; Reporting until 15th of June; Discussion Report ready by August 2006. Contact for further information: bernd.gawlik@jrc.it; lorenzo.galbiati@jrc.it;

Phase I - Dossier Land-use The 50m x50m cell digital elevation model; Geographical The 50m x50m cell digital elevation model; Geographical map with appropriate reference to co-ordinates; Hydrography Map of the channel network in the watershed; Six time series about the aquifer trends in the watershed for the period 1996- 1998 on a monthly basis.; Information on fluxes on main outlets of the channel network; Geo-morphological The 50m x50m cell size soil distribution; Soil textural descriptions; Short description hydrogeological parameters; Land-use The 50m x50m cell land use map; Generic information on agricultural management practice; Climatic conditions Location and data about daily precipitation and temperature (max and min), in 6 stations distributed in the whole watershed, period 1990 – 1999; Pressures Generic data on water quality such as typical values of nutrients, heavy metals, sum parameters, POPs, etc; Information about Principal point sources;

Phase II Test experimental details of the various guidance documents; Emphasis of technical aspects of sampling and related issues Collaborative field trial(s) as feasibility phase; “Reference” laboratory network to eliminate interlaboratory variations; Preparation of longer lasting project in the context of FWP VII.
