Waterbase-Rivers: QualityWater

The QualityWater table contains data on nutrients and organic matter in water measured at Eionet-Water river monitoring stations. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations and Pressures data.
