Official assessment
The latest official test failed at least one quality requirement.
„Concentration en plomb non conforme aux exigences de qualité sur le prélèvement réalisé, une deuxième analyse de contrôle a été effectuée. Nota Bene : Les teneurs ne valent que pour le point d'utilisation où elles ont été mesurées. Compte tenu de l'influence du réseau de distribution d'eau (réseau intérieur et éventuellement branchement public) sur la dissolution des métaux, ces valeurs ne sont pas représentatives de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution.“
