QUALITY STATION SURFACE WATERS: SPECIFIC POLLUTANT STATE

Works of the type "Station qualité cours d'eau" from the repository of works of the Agence Artois-Picardie. The "state" values are those measured for the specific pollutant state. The repository of the Agency's works. The work corresponds to any artificial entity (drilling, factory, lock), natural (source) or virtual (sampling site in a watercourse), geographically located and which performs at least one water-related function within the meaning of the Agency's activities. Some works have legal personality (factory, farm). Since the work can perform several functions in relation to the field of water, it is described by a generic entity containing the data common to all the works and by daughter entities corresponding to the different functions performed by the work. Example: A structure of the type 'Groundwater Access Point' may be used to: - capture water (capture) - measure the height of the aquifer (piezometer) - analyze the quality of the aquifer (quality measurement station)
