Highlight River basin management relies on effective public participation
Rivers are home of many thousands of wildlife species, vital arteries for farmland, a source of cooling for industry, flood regulation, navigation channels and source of drinking water, to name just a few important functions. Such multiple demands on water bodies mean that many different groups need to be actively involved in managing a river basin.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Sep 2014
Average nitrate concentrations in European groundwater increased from 1992 to 1998, but have declined again since 2005. The average nitrate concentration in European rivers declined by 0.03 mg N/l (0.8%) per year over the period 1992 to 2012. The decline in nitrate concentrations reflects the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentration in European rivers has decreased markedly over the last two decades (0.003 mg P/l or 2.1% per year). Also average lake phosphorus concentration decreased over the period 1992-2012 (0.0004 mg P/l, or 0.8% per year). The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents.

Data Waterbase - Rivers
Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

Figure BOD5 concentrations in rivers between 1992 and 2011 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 Bathing water quality (CSI 022) - Assessment published Dec 2010
The quality of water at designated bathing beaches in Europe (coastal and inland) has improved significantly since 1992. Compliance with mandatory values in EU coastal bathing waters increased from 82.3 % in 1992 to 95.6 % in 2009. Compliance with guide values likewise rose from 71.1 % to 89 %. In 1992, 37.4 % of EU inland bathing areas complied with mandatory values compared to 89.4 % in 2009. Similarly, the rate of compliance with guide values moved from 22 % in 1992 to 70.7 % in 2009.

Indicator Assessment Oxygen consuming substances in rivers (CSI 019) - 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

Press Release Troff document Water quality excellent at most of Europe's bathing sites
The water at Europe's beaches, rivers and lakes was generally of high quality in 2013, with 95 % of these sites meeting minimum requirements. Coastal sites performed slightly better than inland bathing waters, the data shows.

Indicator Assessment Nutrients in freshwater (CSI 020) - 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.
