EU Drinking Water Directive (recast) PFAS parameters: Member State compliance measures due by 12 Jan 2026 (PFAS Total / Sum of PFAS transition)

ECHA’s legislation profile for the recast EU Drinking Water Directive indicates a transitional deadline under which Member States must have measures in place by 12 January 2026 to ensure compliance for parameters including “PFAS Total” and “Sum of PFAS,” and suppliers will be required to monitor those parameters. Compliance teams supporting EU water suppliers, laboratories, and regulated entities should ensure monitoring programs, analytical capability, and documentation are aligned to the PFAS parameter requirements by this date.
