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.

Elevation, at a certain location and time, of the water table or piezometric surface of an aquifer.

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

The quiet urban landscape areas include relatively large, continuous open spaces of at least regional importance with a high recreational function and corresponding development for leisure and recreation. Its importance lies in the balancing function to the noisy and densely populated areas of the agglomeration of Luxembourg. The quiet urban landscape close to the residential area allows, for example, extensive walks with only occasional crossing of areas with higher noise levels.

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.

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.

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.
