Groundwater quantitative status
The Water Framework Directive requires assessment of the quantitative status of groundwaters. Assessment is based on the changes in groundwater level. ... The WFD requires that all water bodies be in good status by 2015, or at the latest by 2027. Good status represents the water body condition being as it would be with little or no human impact. ... The assessment of groundwaters also includes chemical status. ...
Surface waters chemical status
The Water Framework Directive (WFD) requires assessment of the chemical status of surface waters. Assessment is based on a list of priority substances. EU-wide standards are set for these substances. ... If concentrations exceed the standard in a water body, the water body fails to meet good chemical status. ...
Groundwaters chemical status
% of groundwater area is in good chemical status The Water Framework Directive requires assessment of the chemical status of groundwaters. Assessment is based on threshold values. ... If concentrations exceed the threshold in a groundwater body, the water body fails to meet good chemical status. - Groundwater chemical status in the WFD refers to the quality of underground water in terms ...

Quality elements for natural flow and physical features
The natural flow and physical features of a water body are important to enable good ecological status. ... These features are commonly altered, and their assessment of changes to the natural flow rate and shape of the water are an important support to the assessment of overall ecological status. ... In rivers, the assessment also includes river continuity, where for example, barriers can impede the passage of migratory fish. ...
Ecological status in surface waters
The Water Framework Directive (WFD) requires assessment of the ecological status of surface waters. This is an expression of the quality of the structure and functioning of the water body. ...

Surface water bodies: River basin specific pollutants [overview chart]
The dashboard shows the river basin-specific pollutants identified as locally important and used as a supporting quality component for the assessment of ecological status or potential of surface water ...
Biological quality elements
Countries consider biological quality elements such as phytoplankton, macrophytes, phytobenthos, benthic invertebrate fauna and fish to assess the ecological status of rivers, lakes and transitional and ... Most countries use 1 to 3 biological quality elements in their assessment. ... If the species present are those which would be expected without, or with little human influence, the status would be good or high for that particular element. ...
