Official assessment
The latest official test passed all quality requirements.
„Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Cependant, les valeurs de chlore mesurées lors de ce contrôle sont élevées. Ceci peut occasionner une gêne importante pour les usagers (objectif souhaitable : 0,1 mg/l de chlore libre en tout point de la distribution).“
