Indicator Assessment Oxygen consuming substances in rivers (CSI 019) - Assessment published Oct 2012
Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2010 (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

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Oct 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 11% between 1992 and 2010 (from 2.5 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being more than halved between 1992 and 2010 (54% decrease). Also average lake phosphorus concentration decreased over the period 1992-2010 (by 31%), the major part of the decrease occurring in the beginning of the period, but is still ongoing. 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.

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

Data Waterbase - Emissions to water
Emissions to water are an important element (describing the pressure) in assessment of the state of Europe’s environment (SoE). This database contains data on emissions of nutrients and hazardous substances to water, aggregated within River Basin Districts (RBDs), in the EEA member countries. The reporting process, endorsed by the Water Directors, and this publication of the data, enables all stakeholders to use the data and contributes to streamlining with other reporting processes.

•    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.

Figure Inland bathing water quality in the European Union, 1990-2010
The figure shows the bathing water quality in different European countries over time 1990, 7 EU Member States; 1991 to 1994, 12 EU Member States; 1995-96, 14 EU Member States; 1997 to 2003, 15 EU Member States; 2004, 21 EU Member States; 2005-06, 25 EU Member States; 2007 to 2010, 27 EU Member States. No inland bathing waters are reported from three Member States (Cyprus, Malta and Romania). The quality classes under the New Bathing Water Directive (2006/7/EC) for Hungary and Luxembourg are jointed with compliance categories under the Bathing Water Directive (76/160/EEC)

Indicator Assessment Bathing water quality (CSI 022) - Assessment published Mar 2012
The quality of water at designated bathing waters in Europe (coastal and inland) has improved significantly since 1990. Compliance with mandatory values in EU coastal bathing waters increased from just below 80 % in 1990 to 92.1 % in 2010. Compliance with guide values likewise rose from over 68 % to 79.5 % in 2010. Compliance with mandatory values in EU inland bathing waters increased from 52 % in 1990 to 90.2 % in 2010. Similarly, the rate of compliance with guide values moved from 36.4 % in 1990 to 60.5 % in 2010.
