Official assessment
The authorities have not published an overall verdict for this water.
„Eau d’alimentation conforme aux limites de qualité en vigueurs mais non satisfaisante aux références de qualité pour le paramètre fer total et pour le paramètre turbidité. Il est demandé de remédier à la situation de non-conformité constatée. En attendant, l'eau reste consommable. Les inconvénients d’une eau trop riche en fer sont d’ordre principalement ménager et organoleptique (odeur, couleur, saveur).“
