  • Drinking water shortage (level « red »)

  • Drinking water shortage (level « orange »)

  • The surface water typology was determined on the basis of geographical , geological, morphological and hydrological characteristics. The Luxembourgish surface water typology comprises six types. For all six types the reference conditions, which would be achieved if there were no anthropogenic pressures impacting surface waters, are described in fact sheets. The reference conditions correspond to the high status of surface water bodies.

  • A groundwater body is a distinctive volume of groundwater inside one or more aquifers. The identification of a groundwater body is made by geological criteria. A groundwater body is a management unit in order to evaluate the environmental objectives (good status) according to article 6 of the national water law of the 19th December 2008.

  • The chemical status of the water bodies is assessed as being good or failing to achieve good chemical surface. The definition of good chemical status is based on the annex X of the water framework directive which contains a list of priority substances and environmental quality standards (EQS) for each of these substances. This list is regularly updated in compliance with the directive 2008/105/EC and its revisions.

  • Overall evaluation of the hydromorphological status per surface water body. It is a “pessimistic assessment” because only the worst of the two parameters morphology an continuity is retained. The hydromorphological status is assessed in 5 classes.

  • The ecological status of the natural waterbodies is assessed in 5 classes going from 1 to 5 (high, good, moderate, poor, bad). The classification of the ecological status is based on the biological quality elements and the physico-chemical quality elements and in some cases also the hydromorphological quality elements.

  • The global status of a surface water body is determined by its ecological and chemical status.

  • The surface water of Luxembourg are subdivided in 102 water bodies. The identification of water bodies is based on geographical and hydrological determinants. 3 surface water bodies are integrated in the river basin of the "Chiers", part of the river basin district of the Meuse. 99 surface water bodies are integrated in the river basin of the "Moselle", part of the river basin district of the Rhine.

  • The ecological status of the natural waterbodies is assessed in 5 classes going from 1 to 5 (high, good, moderate, poor, bad). The classification of the ecological status is based on the biological quality elements, physico-chemical quality elements and in some cases also the hydromorphological quality elements.
