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

The geostatistical interpolation map shows in real time the most probable distribution of the pollutant ozone between the different fixed measurement points that make up the telemetric network of Luxembourg, this at a resolution of 1km2.

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 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 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.
