HVD - Annex 2 Earth Observation and Environment - Water - Raw data of substances analysed in surface water suspended solids in Luxembourg - 2020 (3rd watchlist) (LU-SW-WL)

Network of measurement stations for the period from 2015 to 2020, established as part of the surface water quality monitoring program in accordance with the Water Framework Directive (2000/60/EC). The measurement network includes two components: the surveillance control network and the operational control network. The results of this monitoring program (2015-2020) were used for assessing the state of surface water bodies within the framework of the 3rd management plan. Physico-chemical parameters as well as chemical parameters are sampled at the same station. The location of biological parameter measurement stations may vary slightly.

According to the water framework directive WFD(DIR 2000/60/CE), important physico chemical parameters are measured in the surface water bodies for the assessment of the ecological status. The modalities for this monitoring are stated in the grand ducal Regulation of 30 December 2010 (règlement grand-ducal you 30 décembre 2010 concernant l 'évaluation of the dimension d' eau de surface).

Measurement stations for the qualitative and quantitative monitoring of groundwater for the 3rd cycle (2015-2020) in relation to the Water Framework Directive (2000/60/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.
