Indicator Assessment chemical/x-molconn-Z Aquaculture production (CSI 033) - Assessment published Sep 2011
European aquaculture production has continued to rapidly increase during the past 15 years due to the expansion of marine production. EU 15 and EFTA countries dominate EU’s aquaculture production, where Norway accounted for nearly 40% of the total European production in 2008, followed by Spain, France, Italy and the United Kingdom. Turkey is the most important producer in the EU7 + EU2 + others, having increased its output by nearly 200% from 2001 to 2008. The major increase in aquaculture production has been in marine salmon culture in northwest Europe and, to a lesser extent, trout culture throughout western Europe and Turkey.  Aquaculture production intensity, as measured per kilometre of coastline length, is two times higher in EU 15 + EFTA countries compared with EU7 + EU2 + other countries. This intensity is likely to continue to rise as marine aquaculture production increases, particularly since the culture of new species, such as cod, halibut and turbot, is becoming more viable. This increase represents a rise in pressure on adjacent water bodies and associated ecosystems, resulting mainly from nutrient release from aquaculture facilities. The precise level of local impact will mainly vary according to species, production techniques and local natural characteristics.

Indicator Assessment Use of freshwater resources (CSI 018) - 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).

Indicator Assessment Bathing water quality (CSI 022) - Assessment published Dec 2010
The quality of water at designated bathing beaches in Europe (coastal and inland) has improved significantly since 1992. Compliance with mandatory values in EU coastal bathing waters increased from 82.3 % in 1992 to 95.6 % in 2009. Compliance with guide values likewise rose from 71.1 % to 89 %. In 1992, 37.4 % of EU inland bathing areas complied with mandatory values compared to 89.4 % in 2009. Similarly, the rate of compliance with guide values moved from 22 % in 1992 to 70.7 % in 2009.

Indicator Assessment 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.

Indicator Assessment Bathing water quality (CSI 022) - Assessment published Jan 2009
The quality of water at designated bathing beaches in Europe (coastal and inland) has improved throughout the 1990s into 2000's. In 2006, 96 % of coastal bathing waters and 89 % of inland bathing waters complied with the mandatory standards.

Indicator Assessment Chlorophyll in transitional, coastal and marine waters (CSI 023) - Assessment published Jan 2009
The highest summer chlorophyll-a concentrations were observed in coastal areas and estuaries and are at many locations associated with nutrient inputs from major rivers. Of the 413 stations reported to the EEA in 2005 with more than 5 years of observations, decreasing trends in summer chlorophyll-a concentrations were found at 7% of stations, increasing trends were found at 8% of stations, and the majority of stations (85%) indicate no statistically significant change in concentration. The stations with descreasing trends are located either in the Baltic Sea or along the coast of Italy.

Indicator Assessment Chlorophyll in transitional, coastal and marine waters (CSI 023) - Assessment published Jul 2011
In 2008, the highest summer chlorophyll-a concentrations were observed in coastal areas and estuaries where nutrient concentrations are high, namely in the Gulf of Riga, the Gulf of Finland and along the coast of France and Belgium. Although nutrient concentrations in some European sea areas decreased from 1985 to 2008 (see Core Set Indicator 21), these changes were not clearly reflected in chlorophyll-a concentrations: of the 546 stations reported to the EEA the majority of the stations (89%) indicated no statistically significant change. Changes were detected mainly in Finnish, Dutch, Norwegian, Swedish and Italian coastal waters. At the Finnish and Swedish monitoring stations chlorophyll-a concentrations showed both decreasing and increasing trends, whereas in Italy, Netherlands and Norway concentrations were mainly decreasing. An analysis of changes based on satellite imagery show significantly increasing trends of ocean colour (equivalent to chl-a)along the Mediterranean coast, whereas trends are significantly decreasing in large parts of the central Mediterranean and Black Seas. It also shows significantly increasing trends in the Baltic Sea, but here the analysis is less certain.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Jan 2009
Nitrate concentrations in Europe's groundwaters increased in the first half of 1990s and have then  remained relatively constant. The average nitrate concentration in European rivers has decreased approximately 10 % since 1998 from 2.8 to 2.5 mg N/l, reflecting the effect of measures to reduce agricultural inputs of nitrate. Nitrate levels in lakes are in general much lower than in rivers, but also in lakes there has been a 15 % reduction in the average nitrate concentration. Phosphorus concentrations in European rivers and lakes generally decreased during the last 14 years, reflecting the general improvement in wastewater treatment and reduced phosphate content of detergents over this period.

Indicator Assessment Oxygen consuming substances in rivers (CSI 019) - Assessment published Jan 2009
Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2006, corresponding to the general improvement in wastewater treatment (Fig. 1).   EEA water quality indicators have up to now presented European and regional overviews and country comparison. However, water quality data at national level may not be relevant or sufficient for some countries, and EEA will in the coming years change its indicators to reflect concentration levels and trends at River Basin District (RBD) level to duly reflect local and regional differences in water quality.

Indicator Assessment Urban waste water treatment (CSI 024) - Assessment published Jan 2009
Wastewater treatment in all parts of Europe has improved during the last 15-20 years. The percentage of the population connected to wastewater treatment in the southern, south-eastern and eastern Europe has increased during last ten years, but is still relative low compared to the central and northern Europe.
