Waterbase-Rivers: QualityWater

Data Table

This page was archived on 05 Dec 2016 with reason: Other (The dataset is replaced by Waterbase - Water Quality dataset, which combines Waterbase - Rivers, Lakes and Groundwater into one. It's available at http://www.eea.europa.eu/data-and-maps/data/waterbase-water-quality/.)

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