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.

Figure Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2011
Concentrations are expressed as annual mean concentrations. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per country is given in metadata (see downloads and more info). BOD7 data has been recalculated into BOD5 data. If data on total ammonium are not available, data on ammonium are included into the data series.

Figure BOD5 concentrations in rivers between 1992 and 2011 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.
