Status of the water bodies 2009

According to the water framework directive (Directive 2000/60/CE), the biological parameter fish are monitored in surface water bodies in order to determine the ecological status. Fish react sensitively to the continuity and the hydrological flow of surface water. Fish are therefor sampled in the SWB which have deficits here. The methodology applied for sampling is the standard NF EN 14962:2006 "water quality − guidance on the scope and selection of fish sampling methods".

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.

Drinking water shortage (level « orange »)

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.

The surface water of Luxembourg are subdivided in 106 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. 103 surface water bodies are integrated in the river basin of the "Moselle", part of the river basin district of the Rhine.

Quantitative status of the water bodies 2009

Representation of heavily modified waterbodies which have been physically altered by human activity that they can not achieve good ecological status as defined by the water framework directive (DIR 2000/60/CE) and that no technical feasibility or cost-effective option exist to stop that human activity. These water bodies have the good ecological potential as the environmental objective. They have nevertheless to achieve good chemical status.
