Figure Proportion of classified water bodies in different RBDs affected by pollution 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 Phosphorus concentrations in lakes (total phosphorus) between 1992 and 2011 in different geographical regions of Europe.
The data series per region are calculated as the average of the annual mean concentrations 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) - Assessment DRAFT created Sep 2013
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2005. On average, the nitrate concentration in European rivers declined by 0.5 mg N/l over the period 1992 to 2011 (20% relative to the average concentration), 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- On average concentrations declined by 0.08 mg P/l between 1992 and 2011 (72% decrease relative to the average concentration). Also average lake phosphorus concentration decreased over the period 1992-2011 (on average by 0.008 mg P/l, or 27% relative to the average concentration). 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.

Highlight Blue-green algae - check the water before you swim
Most beaches, lakes and rivers in Europe were clean and healthy last year. But water quality can be affected by many unforeseen factors, including sewage, agricultural waste and algae. The European Environment Agency (EEA) recommends checking local water quality information before you jump in.

Press Release Europe’s bathing waters continue to improve
Ninety-four per cent of bathing sites in the European Union meet minimum standards for water quality, according to the European Environment Agency's annual report on bathing water quality in Europe. Water quality is excellent at 78 % of sites and almost 2 % more sites meet the minimum requirements compared to last year's report.

Indicator Assessment chemical/x-pdb Impacts and pressures (WFD 001) - Assessment DRAFT created Apr 2013
The pressures reported to affect most surface water bodies are pollution from diffuse sources causing nutrient enrichment, and hydromorphological pressures causing altered habitats. Lakes are generally least affected by pressures and their impacts. Pollution from diffuse sources is reported for a larger proportion of water bodies than pollution from point sources for all water categories except transitional waters. The highest proportion of water bodies affected by hydromorphological pressures and altered habitats impact is found for rivers.

Indicator Assessment chemical/x-pdb Chemical status (WFD 002) - Assessment DRAFT created Apr 2013
This indicator summarises the results from the Water Framework (WFD) River  Basin Management Plans (RBMP) on chemical status of groundwater and surface waters. The results should be interpreted cautiously, since chemical monitoring as reported in the first RBMPs was incomplete, and information is not always comparable between Member States.  The results from the first showed: Poor chemical status for groundwater, by area, is about 25 % across Europe. A total of 16 Member States have more than 10 % of groundwater bodies in poor chemical status; this figure exceeds 50 % in four Member States. Excessive levels of nitrate are the most frequent cause of poor groundwater status across much of Europe.   Poor chemical status for rivers, lakes, and transitional and coastal waters does not exceed 10 %, aggregated across Europe as a whole. Notably, the chemical status of many of Europe’s surface waters remains unknown, ranging between one third of lakes and more than half of transitional waters. A total of 10 Member States report poor chemical status in more than 20 % of rivers and lakes with known chemical status, whilst this figure rises to above 40 % in five Member States. A total of 10 Member States report poor chemical status in more than 20 % of rivers and lakes with known chemical status, whilst this figure rises to above 40 % in five Member States.   Polycyclic aromatic hydrocarbons (PAHs) are a widespread cause of poor status in rivers. Heavy metals are also a significant contributor to poor status in rivers and lakes, with levels of mercury in Swedish freshwater biota causing 100 % failure to reach good chemical status. Industrial chemicals such as the plasticiser di-(2-ethylhexyl) phthalate (DEHP) and pesticides also constitute widespread causes of poor chemical status in rivers.  Six Member States report poor chemical status in transitional waters to be more than 50 % of the water bodies with known chemical status. PAHs, the antifouling biocide tributyltin (TBT) and heavy metals are the most common culprits.  Six Member States report all their coastal waters as having good chemical status, although in five others, poor chemical status exceeds 90 % of those water bodies with a known chemical status. A variety of pollutant groups contribute to poor status in coastal waters, reflecting a diverse range of sources.

Indicator Assessment chemical/x-pdb Ecological status or potential (WFD 003) - Assessment DRAFT created Apr 2013
More than half of the surface water bodies in Europe are reported to be in less than good ecological status or potential, and will need mitigation and/or restoration measures to meet the WFD objective.  River water bodies and transitional waters are reported to have worse ecological status or potential than water bodies in lakes and coastal waters.

GIS Map Application Biological elements in rivers and lakes
This viewer with 4 maps shows the ecological status (i.e. status or potential) of macroinvertebrates and phytobenthos in European rivers (i.e. rivers and canals) potentially impacted by general degradation and of macrophytes and phytobenthos in European lakes (i.e. lakes and reservoirs) potentially impacted by eutrophication, respectively. 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 ecological status in rivers or lakes is displayed as classified cartograms in a country-level map: it displays the distribution of status classes per country as one pie chart for each country. This can be used to compare the situation in your country with that in other countries. When the map is zoomed in to a more detailed scale individual station points are visible instead of classified cartograms.
