Surface water quality element status

Ecological status is determined for rivers, lakes, transitional, and coastal waters based on biological quality elements (phytoplankton, macrophytes, phytobenthos, benthic invertebrate fauna and fish), and supporting physico-chemical (nutrients, oxygen condition, temperature, transparency, salinity and river basin specific pollutants (RBSPs)) and hydromorphological quality elements. The Water Framework Directive (WFD) specifies which elements are to be assessed for each water category and requires that biological and supporting quality elements achieve at least good status.

The dashboards below provide an overview of the different results related to quality element status. Further dashboards and items are available in the WISE Freshwater resource catalogue.

Disclaimer
Caution is advised when comparing Member States and when comparing the first and second RBMPs, as the results are affected by the methods Member States have used to collect data and often cannot be compared directly.
