What new scientific tasks will ECHA undertake under the EU’s updated water protection legislation?

Under the EU’s updated water protection legislation, ECHA will provide the technical and scientific basis to support the European Commission in decision-making on water pollutants; prepare scientific reports for identifying priority substances for surface water and groundwater pollutant lists—including developing and updating related environmental quality standards; identify substances for inclusion on watchlists for surface and groundwater; propose harmonized environmental quality standards for river basin-specific pollutants and harmonized threshold values for regional groundwater pollutants; report every six years on potential updates to main pollutant lists and associated water quality standards; and report every three years on watchlist substances using monitoring data from EU member states.

When did the revised EU water protection framework enter into force, and what directives does it amend?

The revised EU water protection framework was adopted in March 2026 and entered into force on May 11, 2026; it strengthens the protection of Europe’s waters by amending the EU’s Water Framework Directive, the Environmental Quality Standards Directive, and the Groundwater Directive.
