The maps show the monitoring sites in Europe that exceeded effect or quality thresholds for (left) imidacloprid in surface waters (right) atrazine in groundwater in the year 2020. The classification of 'unknown’ for some monitoring sites means that the substance was detected but the concentration was below the limit of quantification (LoQ) and the LoQ was higher than the assessment threshold. This means that it is impossible to determine whether there was an exceedance or not. The data reported for imidacloprid in surface waters cover 16 countries. The data reported for atrazine cover 18 countries. The monitoring results are reported under the Water Information System for Europe State of Environment (WISE SoE) reporting, more specifically WISE 6, and the spatial data for the monitoring sites are reported under the Water Framework Directive and the WISE 5 Spatial data reporting.
