Figure Nitrate concentrations in rivers 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 included per sea region is given in parentheses.

Figure Nitrate concentrations in groundwater 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 groundwater bodies (GWBs) in the region. Only complete series after inter/extrapolation are included (see indicator specification). The number of groundwater bodies included per geographical region is given in parentheses.

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.

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.
