Indicator Assessment Oxygen consuming substances in rivers (CSI 019/WAT 002) - Assessment published Dec 2010
Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2009 (Fig. 1), mainly due to general improvement in wastewater treatment. See also WISE interactive maps:   Mean annual BOD in rivers and Mean annual Total Ammonium in rivers

Figure Percentage of European coastal bathing waters complying with mandatory value (or with at least sufficient quality) and meeting guide value (or with excellent quality) for the year 2012 by country
Countries arranged by the percentage of compliance with mandatory value or at least sufficient quality. Five Member States (Austria, the Czech Republic, Hungary, Luxembourg and Slovakia) and Switzerland have no coastal bathing waters. The quality classes under the New Bathing Water Directive (2006/7/EC) are jointed with compliance categories under the Bathing Water Directive (76/160/EEC).

Highlight River Rhine commended for river basin management
The River Rhine has won the first ever International River Foundation (IRF) European River Prize, which is given for remarkable achievements in integrated river basin management. The other finalists were the Órbigo River in Spain, the Upper Drau in Austria, and the Mura-Drava-Danube in Central Europe.

Figure Nitrate concentrations in rivers between 1992 and 2009 in different geographical regions of Europe.
The data series per region are calculated as the average of the annual mean for river monitoring stations in the region. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per geographical region is given in parentheses.

Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - Assessment DRAFT created Apr 2012
•    Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2004. •    The average nitrate concentration in European rivers decreased by approximately 13% between 1992 and 2009 (from 2.5 to 2.1 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate. •    Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being halved between 1992 and 2009 (52% decrease). Also average lake phosphorus concentration decreased over the period 1992-2009 (by 22%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. •    Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Figure Projected change in average annual and seasonal river flow
Projected change in mean annual and seasonal river flow between the climate change scenario (SRES A1B, 2071-2100) and the control period (1961-1990). Simulations with LISFLOOD based on an ensemble of 11 RCMs.

GIS Map Application Macroinvertebrates in rivers
The map shows the ecological status or potential of European rivers, expressed using a specific biological quality element (BQE), namely macroinvertebrates, 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.
