Figure Nitrate concentrations in rivers between 1992 and 2010 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 included per sea region is given in parentheses.

Figure Nitrate concentrations in rivers between 1992 and 2010 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 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.

•    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.
