GIS Map Application Phytobenthos in rivers
The map shows the ecological status or potential of European rivers, expressed using a specific biological quality element (BQE), namely phytobenthos, reported by EEA member countries via WISE. The ecological status class is assessed by each country according to their national classification system, following the principles established by the Water Framework Directive (WFD). The assessment may be based by one or more samples taken during the year of reporting. The map displays the latest reported information under the WISE SoE reporting, so the year of reference may vary. Note that under the WFD reporting, the ecological status or potential based on all BQEs combined is represented by the BQE with the worst class - the "one-out-all-out" principle - which does not apply here, given that only one BQE is represented and that the reporting is done annually. The purpose of the map to enable the user to compare values per country or per monitoring station, depending on the scale of visualisation.

Figure BOD5 concentrations in rivers between 1992 and 2010 draining to different sea regions of Europe
The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per sea region is given in parentheses. There were no stations with consistent data series on BOD7 in rivers draining to the Arctic Ocean. BOD7 data has been recalculated into BOD5 data.

Indicator Assessment chemical/x-pdb Ecological status or potential
More than half of the surface water bodies in Europe are reported to be in less than good ecological status or potential, and will need mitigation and/or restoration measures to meet the WFD objective.  River water bodies and transitional waters are reported to have worse ecological status or potential than water bodies in lakes and coastal waters.

Highlight Blue-green algae - check the water before you swim
Most beaches, lakes and rivers in Europe were clean and healthy last year. But water quality can be affected by many unforeseen factors, including sewage, agricultural waste and algae. The European Environment Agency (EEA) recommends checking local water quality information before you jump in.
