Qualitative data reported under the Drinking Water Directive (DWD) focus on a short list of pesticides and their compliance with the DWD even though EU Member States monitored a broad range of pesticides in their countries. The compliance rate for each substance is attributed solely to large Water Supply Zones, whereas the reporting of compliance for decentralised small wells is not obliged under the Directive (and will also not monitored on regular frequency). Furthermore, the point of compliance (and monitoring) is not the raw water from the drinking water source rather than the point of human consumption after treatment. While the amount of compliance will give a hint to main pesticide problems within EU Member States, data are hardly comparable to other databases.
