Water: Monitoring data and statistics
Links to current monitoring data on bodies of water, the possibility of obtaining data, information about extreme value statistics, data on the water withdrawn and returned and the Hydrological Yearbook of Switzerland.

Traces of artificial, rather persistent substances are found mainly in conurbations and regions used for intensive agriculture. This is shown by the analyses of the National Groundwater Monitoring NAQUA.
