This page was archived on 16 Sep 2020 with reason: Other (replaced by two other datasets https://www.eea.europa.eu/data-and-maps/data/waterbase-water-quality-icm and https://www.eea.europa.eu/data-and-maps/data/waterbase-biology)

The dataset contains time series of nutrients, organic matter, hazardous substances and other chemicals in rivers, lakes and groundwater, as well as data on biological quality elements (BQEs) such as phytobenthos and macroinvertebrates in rivers and lakes. A list of monitoring site identifiers with selected attributes, reported through WFD and WISE Spatial data reporting, is added to dataset as spatial reference. The data has been compiled and processed by EEA. Please refer to the metadata for additional information.
