Average concentrations of nutrients in European groundwaters and surface waters (1992-2009) Fig. 1a: Nitrate in groundwater; Fig. 1b Nitrate in rivers; Fig. 1c Orthophosphate in rivers; and Fig. 1d: Total phosphorus in lakes: Concentrations are expressed as annual mean concentrations. 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 metadata (see downloads and more info).

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

Coastal bathing water quality in the European Union, 1990-2011: The figure shows the bathing water quality in different European countries over time: 1990, 7 EU Member States; 1991 to 1994, 12 EU Member States; 1995-96, 14 EU Member States; 1997 to 2003, 15 EU Member States; 2004, 21 EU Member States; 2005-06, 25 EU Member States; 2007 to 2011, 27 EU Member States. Five Member States (Austria, the Czech Republic, Hungary, Luxembourg and Slovakia) have no coastal bathing waters. The quality classes under the New Bathing Water Directive (2006/7/EC) are jointed with compliance categories under the Bathing Water Directive (76/160/EEC).

Chlorophyll-a concentrations in European seas in 2010: The map shows Chlorophyll-a concentrations in European coastal and open seas in 2010. The class boundaries “high”, “moderate” and “low” concentration are determined by the 80/20 percentiles of the data set in each sea (sub)region. The low category refers to values within the lowest 20th percentile and the high category refers to values within the upper 20th percentile of concentrations.

Waterbase - Rivers: Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

Nutrients in transitional, coastal and marine waters (CSI 021) - Assessment published Jul 2011: Decreasing nutrient concentrations were found in the North Sea and in the Baltic Sea. In the Mediterranean and Black Sea, the lack of temporally and spatially comprehensive time series does not allow an overall assessment. In 2008, the highest concentrations of oxidized nitrogen were found in the Gulf of Riga, and in Lithuanian, Swedish, German, Belgian, and Scottish coastal waters. Between 1985 and 2008, 12% of all the stations in the European seas reported to the EEA showed decreasing trends of oxidized nitrogen concentrations. These trends were more evident in the open Baltic Sea and in the Dutch and German coastal waters in the North Sea. In 2008, the highest orthophosphate concentrations were found at Finnish coastal stations in the Gulf of Finland, the Gulf of Riga, German, Belgian, French, and Scottish coastal waters. Between 1985 and 2008, 15% of all the stations in the European seas reported to the EEA showed a decrease in orthophosphate concentrations, mainly because of improved waste water treatment. This decrease was most evident in Norwegian, Lithuanian, Danish, Belgian and Dutch coastal water stations, and in the open waters of the North and Baltic Seas.
