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.

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 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 hydromorphological status was determined by a monitoring compliant with the Water Framework Directive (Directive 2000/60/EU). The elaboration of a structural quality mapping is one part of this monitoring. Within the scope of the work on the structural quality mapping, a total of 31 parameters in the area of the river bed, the river bank and the floodplain are assessed so that the structural quality mapping contains detailed information on the river morphology and the river continuity. In this case, the evaluation of the mapped sections is based on seven classes. The areas river bed, left river bank, right riverbank, left floodplain and right floodplain are represented in 5 strips.

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

In 2018, the environmental administration organised a nationwide air quality measurement campaign in collaboration with 36 participating municipalities and myenergy. More specifically, it is a national measurement campaign of NO2 by passive tubes in the context of the national air quality program and the "Klimapakt Loftqualitéit". The campaign aims to raise awareness and inform municipalities and their inhabitants about the air quality in their respective municipalities, motivate municipalities to contribute to improving their air quality, and demonstrate the efforts undertaken by municipalities for future communications.
