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.

GIS Map Application Nitrites in groundwater by countries and WFD gw bodies
The map shows the mean annual concentrations of Nitrites (NO2) measured at WISE SoE groundwater monitoring stations during the period 2000 – 2011. All data are annual means aggregated by countries (visible when the map is zoomed to the scale of 1 : 6 000 001 and less detailed) or by WFD groundwater bodies (visible when the map is zoomed to the scale of 1 : 6 000 000 and more detailed).
