Status of the water bodies 2009

Chemical status of the water bodies 2009

Luxembourg's surface water bodies have been grouped into so-called "study zones", which essentially correspond to the country's major catchment areas. Seven study zones have been designated in total.

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.

According to the Water Framework Directive (Directive 2000/60/EC ), macrophytes and diatoms are monitored as two sub-elements of the aquatic flora. Macrophytes are particularly sensitive to organic pollution, trophy and hydromorphology. The diatom assemblages are different in function of concentrations of nutrients and organic pollutants.
