GIS Map Application Macrophytes in lakes
This map shows the ecological status (i.e. status or potential) of macrophytes in European lakes (i.e. lakes and reservoirs) potentially impacted by eutrophication. The ecological status class of a country's waterbodies (or stations) is assessed by each country according to their national classification system, following the Water Framework Directive. The assessment may be based by one or more samples measured during the year of reporting. The purpose of this map is to show ecological status of individual biological quality elements (BQEs) and the major impact types. In comparison, the map layer "Ecological status or potential of water bodies" in the WFD Surface Water Viewer (http://www.eea.europa.eu/themes/water/interactive/soe-wfd/wfd-surface), displays ecological status or potential based on all BQEs combined, represented by the BQE with the worst class (the "one-out-all-out" principle). Moreover, the maps based on SoE-WISE biological data will be updated yearly, whereas the WFD database will be updated every 6th year.

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) - 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.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Dec 2010
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, and have remained relatively constant since then. The average nitrate concentration in European rivers decreased by approximately 9 % between 1992 and 2008 (from 2.4 to 2.2 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 almost halved between 1992 and 2008 (47 % decrease). Also average lake phosphorus concentration decreased over the period 1992-2008 (by 26%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflect 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.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Oct 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 11% between 1992 and 2010 (from 2.5 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being more than halved between 1992 and 2010 (54% decrease). Also average lake phosphorus concentration decreased over the period 1992-2010 (by 31%), the major part of the decrease occurring in the beginning of the period, but is still ongoing. 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.
