Directive (EU) 2026/805 of 30 March 2026 constitutes a major revision of the European Union’s water legislation. By simultaneously amending the Water Framework Directive (2000/60/EC), the Groundwater Directive (2006/118/EC), and the Environmental Quality Standards Directive (2008/105/EC), the text aims to align the protection of water resources with the European Green Deal’s “zero pollution” ambition.
