The chemical status of the surface water bodies is assessed as being good or failing to achieve good chemical status. The assessment of the chemical status for the second river basin management plan is based on the list of substances of directive 2008/105/EC and the environmental quality standards established by the new directive 2013/39/EC.
Evaluation of the quality element “morphological conditions” per surface water body
The geostatistical interpolation map shows in real time the most probable distribution of the pollutant fine particles (PM10) between the different fixed measurement points that make up the telemetric network of Luxembourg, this at a resolution of 1km2.

The "good ecological potential" is the environmental quality objective defined by the water framework directive for artificial and heavily modified surface water bodies. The ecological potential is assessed in four classes ranging from 1 to 4 (good and higher, moderate, poor, bad). The classification of the ecological potential is based on the biological, physico-chemical and in some cases also the hydromorphological quality elements.
Risk assessment of the groundwater body regarding the good quantitative state in 2021.
According to the WFD (Water framework directive) the assessment of the stauts of the surface water bodies is based on the evaluation of the monitoring results. According to Article 8 of the WFD, Member States must ensure the establishment of monitoring programs, inter alia, for surface waters. The monitoring of the surface water bodies is carried out at surveillance monitoring stations and operational measuring points. For surface waters, the WFD also foresees an investigative monitoring.
Drinking water shortage (level « orange »)
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".
Overall evaluation of the hydromorphological status per surface water body. The assessment of the hydromorphological status is based on the mapping and the assessment of the structural quality of the Luxembourgish watercourses. The quality element “morphology” has not been covered in the framework of the structural quality mapping, but only the two quality elements related to continuity and morphology. The hydromorphological status is assessed in 5 classes.
