Dataset Direct Download Service (WFS): STATE OF PLAY 2013 OF THE RIVIERES CANALS EN GRAND EST

The European Union has set its Member States the objective of preserving and improving the status of surface waters. The definition of this state and its monitoring are laid down by the Water Framework Directive (WFD) 2000/60/EC of 23 October 2000 and the associated French regulations, in particular the Decree of 25 January 2010 on methods and criteria for assessing the ecological status, chemical status and ecological potential of surface waters. Two “states” of the waters must be established: — ecological status, consisting mainly of biological status and physico-chemistry (general parameters such as dissolved oxygen, nutrients... and specific hazardous pollutants). Ecological status is replaced by the ecological potential for heavily modified water bodies (MEFM) and artificial water bodies (MEA); — chemical status, determined by compliance with the environmental quality standards (EQS) laid down for “priority” substances (heavy metals, pesticides, etc.), having an impact on human health and the environment. The Framework Directive sets environmental outcomes objectives, i.e. achieving good ecological status (or potential) and good chemical status by December 31, 2015, with the exception of water area covered by postponements to 2021 or 2027, or subject to less stringent targets. The “Statements 2013” prepared by the Water Agencies for the three basins covering the Lorraine region (Rhin-Meuse, Seine-Normandie for the west of the Meuse and Rhône-Méditerranée for the south of the Vosges) were used to create the SIG layer (COURSDEAU_ETAT_LIEUX_2013_BRM_RMC_SN). The state of the site has been compiled using data from 2010 and 2011 or, if not available, data from previous years (2008 for the oldest). This layer made it possible to produce the document “The ecological and biological status of rivers, canals and water bodies of Lorraine — State of play 2013” published on the website on 30 December 2014. The published document presents only the ecological status and one of its two components, biological status, as the latter corresponds to the competences of the hydrobiology laboratory of DREAL with the exception of ichtyofaune. Chemical status maps are provided at the end of the document for information.
