Figure Concentrations of nitrate and orthophosphate in rivers and total phosphorus in lakes in the period 1992–2007
Total number of stations in parenthesis. Concentrations are expressed as weighted means of annual mean concentrations for rivers and lakes. Only stations with time series of seven years or more are included.

Daviz Visualization D source code Nutrient trend
The data series are calculated as the average of annual mean concentrations for groundwater bodies/river stations/lake stations in Europe. Only complete series after inter/extrapolation are included (see indicator specification). The number of groundwater bodies/river stations/lake stations included per country is given in the notes below the individual substance charts.

Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - 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.
