Indicator Assessment Oxygen consuming substances in rivers (CSI 019/WAT 002) - Assessment published Feb 2015
Concentrations of biochemical oxygen demand (BOD) and total ammonium have decreased in European rivers in the period 1992 to 2012 (Fig. 1), mainly due to general improvement in waste water treatment.

Figure 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.

Figure C source code header Estimated global warming at which the onset of the events could occur versus their impact
Temperature increase (above 1990 level) at which the various events could occur and an estimate of their impact. The impact scale has subjective qualifications (‘minor’, ‘notable’, ‘major’ and ‘devastating’), which were assigned on the basis of the geographical scale (from ‘regional’ to ‘continental’ and ‘global’) and the character of the damages (‘light’, ‘moderate’, ‘heavy’ or ‘extreme’). The level of scientific understanding, as well as the understanding of possible impacts for most of these events is low. The shapes and sizes of the ovals do not represent uncertainties in impact and temperature onset of eventualities and these uncertainties may be significant.

Figure 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

Indicator Assessment Nutrients in freshwater (CSI 020/WAT 003) - Assessment published Feb 2015
Since 2005, average nitrate concentrations in European groundwater have declined and in 2011, the mean concentration had almost returned to the 1992 level. The average nitrate concentration in European rivers declined by 0.03 milligrams per liter of nitrogen (mg N/l) (0.8%) per year over the period 1992 to 2012. The decline in nitrate concentration reflects the effect of measures to reduce agricultural inputs of nitrate, as well as improvements in wastewater treatment. Average orthophosphate concentration in European rivers has decreased markedly over the last two decades (0.003 milligrams per liter of phosphorous (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 concentration reflects both improvements in wastewater treatment and the reduction of phosphorus in detergents.

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.
