Figure Distribution of chemical status of groundwater, rivers, lakes, transitional and coastal waters.
Number of Member States contributing to the dataset: Groundwater (26); Rivers (25); Lakes (22); Transitional (15) and Coastal (20). Percentages shown for rivers, lakes, transitional and coastal are by water body count. Groundwater percentages, however, are expressed by area. The total number of water bodies is shown in parenthesis. Data from Sweden are excluded from surface water data illustrated in the figure. This is because Sweden contributed a disproportionately large amount of data and, classified all its surface waters as poor status since levels of mercury found within biota in both fresh and coastal waters exceed quality standards.

Figure Proportion of classified water bodies in different RBDs affected by hydromorphological pressures, for rivers and lakes (left panel) and for coastal and transitional waters (right panel)
The percentage is based on total number of classified water bodies. See the indicator specification for more details.

Figure Proportion of total number of classified water bodies with identified significant pressures (left column) and impacts (right column), for rivers, lakes, coastal waters, and transitional waters
The percentage is calculated against the total number of classified surface water bodies in Member States reporting the specific pressure or impact type (or any pressure or impact for the blue bars). The number of Member States included is indicated in brackets. See the indicator specification for more details.

Figure Proportion of classified surface water bodies in different RBDs holding less than good ecological status or potential, for rivers and lakes (left panel) and for coastal and transitional waters (right panel)
The figure shows percentage of the total number of classified water bodies. See the indicator specification for more details.

Figure Phosphorus concentrations in lakes (total phosphorus) between 1992 and 2010 in different geographical regions of Europe.
The data series per region are calculated as the average of the annual mean for river 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 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.
