The Directive aims for "good status" for all ground and
surface waters (rivers, lakes,
transitional waters, and coastal waters) in the EU. The purpose of the WFD is to prevent deterioration of the water bodies, enhance status of aquatic ecosystems, reduce pollution from priority substances, promote sustainable water use and contribute to mitigate the effects of floods and droughts. The ecological and chemical status of surface waters are assessed according to the following criteria: • Biological quality (fish,
benthic invertebrates,
aquatic flora) •
Hydromorphological quality such as
river bank structure, river continuity or substrate of the river bed • Physical-chemical quality such as
temperature,
oxygenation and nutrient conditions • Chemical quality that refers to environmental quality standards for river basin specific pollutants. These standards specify maximum concentrations for specific
water pollutants. If even one such concentration is exceeded, the water body will not be classed as having a “good ecological status”. The Water Framework Directive stipulates that
groundwater must achieve "good quantitative status" and "good chemical status" by 2015. Groundwater bodies are classified as either "good" or "poor". On 26 October 2022, the
European Commission published a proposal for amendment of the WFD as well as the 2006
Groundwater Directive (GWD), and the 2008
Environmental Quality Standards Directive (EQSD). The proposal aims to align the directives with the
2020 European Green Deal by updating lists of pollutants, updating quality standards, improving assessment of combination effects and ensuring that the legal framework of the directives can swiftly align with scientific findings. ==Spatial management of river basins==
