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 Correlation between the average country level WUI and the % of area irrigated with surface irrigation systems in 24 EU countries
The chart displays the correlation between the average country level WUI (in m3/€ PPS), among all crops in the country, and the % of area irrigated with surface irrigation systems in 22 European countries, with % of area irrigated with surface irrigation systems below 40% in 2010 (FI, DE, NO, DK, NL, SE, FR, UK, CH, MT, CZ, CY, AT, HU, SI, HR, EL, RO, PL, IT, ES, SK).

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.

Indicator Assessment Use of freshwater resources (CSI 018/WAT 001) - Assessment published Dec 2010
Over the last 10-17 years the Water Exploitation Index (WEI) decreased in 24 EEA countries (Fig.1), as a result of water saving and water efficiency measures. Total water abstraction decreased about 12 %, but one fifth  of Europe's population still lives in water-stressed countries (approx. 113 million inhabitants).
