Map visualisation service (WMS) of the dataset: STATE OF PLAY 2013 OF WATER PLANS IN LARGE EAST

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 follow-up are laid down in 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 hazardous specific pollutants). Ecological status is replaced by the ecological potential for heavily modified water bodies (SMMEs) and artificial water bodies (AMEs); — chemical status, determined by compliance with environmental quality standards (EQS) for so-called “priority” substances (heavy metals, pesticides, etc.), having an impact on human health and the environment. The Framework Directive sets objectives for environmental results, i.e. achieving good ecological status (or potential) and good chemical status by 31 December 2015, with the exception of waters area covered by postponements of deadlines to 2021 or 2027, or targeted by 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 States of the Place have been established using data from 2010 and 2011 or if they are absent, those of previous years (2008 for the oldest). This layer made it possible to produce the document “The ecological and biological status of the rivers, canals and bodies of water 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, the biological state, as the latter corresponds to the competences of the DREAL hydrobiology laboratory with the exception of ichthyfauna. Chemical status cards are provided at the end of the document for information.
