Drinking water quality in Romilly-sur-Seine
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,005 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (22 April 2026)
This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.
3 PFAS (see each substance)

Official assessment
The authorities have not published an overall verdict for this water.
„Compte tenu des paramètres contrôlés, cette eau est conforme aux limites et références de qualité des eaux destinées à la consommation humaine, définies par l'arrêté du 11 janvier 2007, pour l'ensemble des paramètres mesurés. Toutefois, je note une teneur très excessive en chlore ( 0,42 mg/l), nettement supérieure au niveau guide recommandé en distribution de 0,10 mg / litre exprimé en chlore libre, ce qui peut générer à long terme, des risques sanitaires de par la formation de sous-produits de désinfection (dont les THM Trialométhanes). Il est donc indispensable de revoir les conditions de fonctionnement du dispositif de désinfection et d'assurer un suivi rigoureux et régulier, afin de garantir en permanence aux usagers un taux de désinfection de l'eau satisfaisant.“
