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.

Indicator Assessment Use of freshwater resources (CSI 018) - Assessment published Jan 2009
Over the last 10-15 years the Water Exploitation Index (WEI) decreased in 21 EEA countries (Fig.1), mainly in the  in the eastern countries, due to economic and institutional changes and some western countries, as a result of water saving and water efficiency measures. Total water abstraction decreased about 10 %, but nearly half of Europe's population still lives in water-stressed countries (approx. 266 million inhabitants).

Figure Percentage of European coastal bathing waters complying with mandatory value (or with at least sufficient quality) and meeting guide value (or with excellent quality) for the year 2012 by country
Countries arranged by the percentage of compliance with mandatory value or at least sufficient quality. Five Member States (Austria, the Czech Republic, Hungary, Luxembourg and Slovakia) and Switzerland 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).

Highlight River Rhine commended for river basin management
The River Rhine has won the first ever International River Foundation (IRF) European River Prize, which is given for remarkable achievements in integrated river basin management. The other finalists were the Órbigo River in Spain, the Upper Drau in Austria, and the Mura-Drava-Danube in Central Europe.
