The lake "Haute Sure" in Esch-sur-Sûre
The surveillance monitoring is carried out respecting the luxemburgish legislation (règlement grand-ducal du 15 janvier 2016) on 4 monitoring sites. Three of them are located in the international river basin district of the Rhine, one is located in the inernational river basin district of the Meuse.
In the detailed programme of measures, the types of measures related to hydromorphology (HY) and urban wastewater management (SWW) which are defined in the catalogue of measures of the second river basin management plan, were assigned to the individual water bodies. The objective of this assignation is to identify for each water body those measures that will help to reduce the pressures and deficits present in the water body, thereby improving its status or maintaining its good status. The hydromorphological measures include the improvement of the ecological continuity, the renaturation of water courses as well as the regulation of the minimal flow. Some hydromorphological types of measures can have a positive effect on the reduction of floods.
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.
According to the Bathing Water Directive 2006/7/CE were designated 3 bathing water groups in Luxembourg : the reservoir of the Upper Sure , the swimming pond in Remerschen and the swimming pond in Weiswampach which are surveyed at 12 bathing water sites. Every year before the start of the bathing season the list of bathing waters will be published in the Luxembourg press. The bathing season in Luxembourg extends from May 1 to September 30. Legally, the Bathing Water Directive was implemented in Luxemburgish Law with the regulation of the 19th of May 2009 regarding the Bathing Water ( règlement grand-ducal du 19 mai 2009 modifié concernant les eaux de baigande ) into Luxembourg law.
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.
