Water Framework Directive
The Water Framework Directive (WFD; 2000/60/EC) is an EU directive to establish a framework for the protection of all water bodies (including marine waters up to one nautical mile from shore) by 2015. The WFD establishes a programme and timetable for Member States to set up river basin management plans by 2009.
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:
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". Ecological quality ratios are used to determine the water quality status, representing the relationship between measured biological values observed in water bodies, against the relevant reference conditions. A quality ratio of one represents high ecological status, while zero represents bad ecological status.
Article 14 of the directive requires member states "to encourage the active involvement of interested parties" in the implementation of the directive. This is generally acknowledged to be an assimilation of the Aarhus Convention.
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. This revision formally entered into force on 11 May 2026 as Directive (EU) 2026/805. The updated framework expands the list of priority substances to include per- and polyfluoroalkyl substances (PFAS), microplastics, and various pharmaceuticals. It also introduces mandatory "effect-based monitoring" (EBM) to assess the cumulative impact of chemical mixtures on aquatic life. Member States are required to transpose these amendments into national legislation by December 2027.
The Water Framework Directive defines river basin districts as the main unit for management of river basins. These areas have been designated, not according to administrative or political boundaries, but rather according to the river basin (the spatial catchment area of the river) as a natural geographical and hydrological unit. As rivers often cross national borders, representatives from several Member States have to co-operate and work together for the management of the basin (so-called transboundary basins). They are managed according to River Basin Management Plans, which should provide a clear indication of how the objectives set for the river basin are to be reached within the required timescale. Lists of priority substances and pollutants are reviewed every six years.
To facilitate data recording, each stretch of water is given a "Water Framework Directive ID" ("WFDID" or "Waterbody ID"). For example, the stretch of the River Tame, in the West Midlands of England, from the River Blythe to River Anker is designated as GB104028046440.
