This dataset lists water quality monitoring stations located in the Pays de la Loire region of France. It is derived from the national Naïades database, which aggregates water quality data produced by various organizations for purposes such as studies, regulatory compliance, and research. The reference databases underlying Naïades store data from multiple producers and monitoring networks. The dataset is published via the Pays de la Loire regional open data portal and provides free, unauthenticated access, making it useful for environmental monitoring, regional water management, and research on surface or groundwater quality in the region.Origine des données Ces données sont issues de la base nationale Naïades et produites par des organismes (intervenants) pour répondre à un besoin (étude, règlementation, recherche...) puis stockées dans des banques de référence qui peuvent stocker des données de plusieurs producteurs et répondant...
