Identifier	NiD
Short name	NiD_water
Registration status	Released 07 July 2008
Reference URL	http://dd.eionet.europa.eu/datasets/latest/NiD
Name	Evaluation of water quality under the Nitrates Directive.
Keywords	Article V, Eutrophication, Groundwater, NO3, Surface water, Water, water quality
Short Description	Ground- and surface water sampling points to define waterquality based on nitrate concentrations and other parameters
Definition	Data on monitoring stations are collected for each reporting period (4 year period). Full details of the data requested on water are presented in this specification by tables and include characteristics on the water monitoring stations, values for the concentrations of NO3 for each station as well as information on the Nitrate Vulnerable Zones and Potential Vulnerable Zones. Additionally
Methodology for obtaining data	The data requested for Nitrates Directive should be derived from existing national and/or regional monitoring networks within each Member State. The combination of the elements CountryCode, NationalStationCode and StationType must be a unique record in the table. No duplicate records should exist with this combination. Please consider the following when compiling your data delivery: 1. Provide information on the monitoring stations. The station location must represent a point location. 2. Submit NO3 concentrations for groundwater- and surface water monitoring stations sampled during a period of one or more years within the reporting period. 3. Submit information on the trophic state (and eutrophication parameters) for the surface water monitoring stations. 4. Submit data for each sample site (no aggregation of stations). 5. Submit geographical data sets (shapefiles or e00) for the Nitrate Vulnerable Zones and Potential Vulnerable Zones in order to create and update the NVZ database (hosted by JRC). For GIS guidelines go to http://eionet.europa.eu/gis/ . 6. For countries with Whole territory Approach, supply information on the legal act (table WTA). 7. The WTA countries can also supply geographical information on the risk areas in there country. This is optional. 8. Use the templates (XML schemas or Excel) and these specifications to guide you in formatting and collating your data delivery. All are available for download from the data dictionary. 9. Supply data on monitoring stations in XML, Excel or tab-separated ASCII text format. Ensure commas are not used as decimal separators. 10. Upload your data files to your nominated repository: the Central Data Repository at http://cdr.eionet.europa.eu/
