Non-compliant samples
- Seillans, 20 October 2025 (2 samples) – adduc. seillans lonne-fontbrigasse: Eau non conforme aux limites de qualité fixées par le Code de la Santé Publique concernant les eaux destinées à la consommation humaine pour les paramètres bactériologiques.
Full ARS conclusion
Eau non conforme aux limites de qualité fixées par le Code de la Santé Publique concernant les eaux destinées à la consommation humaine pour les paramètres bactériologiques. Eau présentant un risque sanitaire bactériologique. En application des articles R.1321-26 et R.1321-30, il a été demandé la restriction de l'utilisation de l'eau pour les usages de consommation (boisson, lavage des dents et préparation des aliments crus) pour l' ensemble de la population ; ainsi que la réalisation dans les plus brefs délais de la purge, du nettoyage et de la désinfection du réservoir et des réseaux de distribution. Une surchloration (à 0,5 mg/l) devra être maintenue dans les premiers jours suivant la désinfection. Un nouveau prélèvement de contrôle sanitaire est diligenté. Par ailleurs une information de l'ensemble de la populationation et une campagne de distribution en eau embouteillée a été réalisée. La levée d'interdiction d'usage ne pourra être effective qu'après l'obtention de résultats conformes en production et en distribution.
31 sample(s) exceeded a quality reference (indicator such as water temperature or chlorine, without health limit).

Sources and method
- Water quality: results of the health checks of the Regional Health Agencies, via the Hub'Eau API (OFB). A sample is compliant when no parameter exceeds a quality limit (health); quality references are indicators of how the network works. Official results per town: Ministry of Health.
- Restrictions: VigiEau (Ministry of Ecological Transition), queried live from your browser at the town hall location; outlying hamlets may fall in another zone.
- Price: SISPEA observatory (OFB), data declared by each service; where a town has several pricing areas, the median value is shown.
- Rivers: Hub'Eau hydrometry (monthly mean flow QmM). Groundwater: Hub'Eau piezometry (BRGM, ADES), monthly mean of daily levels in metres above sea level (NGF).
