From 1 - 10 / 50
  • 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 as well as its environmental quality standards. The assessment without the ubiquist substances permita to get a differentiated picture of the actual situation.

  • The groundwater bodies are classified according to 6 states: no data available, very good, good, moderate, unsatisfactory, bad.

  • 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 as well as its environmental quality standards.

  • 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.

  • Evaluation of the quality element “morphological conditions” per surface water body

  • 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.

  • The macroinvertebrates are sampled according to the French method IBGN ( indice biologique global normalisé , agences de l' eau 2000). The results allow to classify the surface water bodies into 5 classes : high - good - moderate - poor - bad. Macroinvertebrates are sensitive to the hydromorphology, organic pollution , biological continuity , water regime and acidification. The Macroinvertebrates are one out of four biological parameters of the ecological status of surface water.

  • 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.

  • 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. The assessment without the ubiquist substances permita to get a differentiated picture of the actual situation.

  • The WFD's quantitative status objectives aim to ensure a balance between groundwater withdrawal and recharge.
