Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2009 in 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 per region is given in parentheses.

Waterbase - Groundwater: 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

Phosphorus concentrations in lakes (total phosphorus) 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 lake monitoring stations in the region. Only complete series after inter/extrapolation are included (see indicator specification). There were no stations with complete series after inter/extrapolation in the South and Southeast regions. The number of lake monitoring stations included per geographical region is given in parentheses

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.

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.

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.

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.
