The NAQUA National Groundwater Monitoring provides a nationally representative picture of the status and development of groundwater resources, both in qualitative and quantitative terms.
Within the framework of the NAQUA National Groundwater Monitoring, the FOEN records the status and development of groundwater resources at more than 600 monitoring sites in Switzerland.
The monitoring network of the National Groundwater Monitoring consists of four modules
The QUANT module records groundwater quantity, while the SPEZ and TREND modules record groundwater quality. The ISOT module observes stable water isotopes in precipitation and in flowing waters.
