Messnetz Beobachtung Grundwasserqualität
Samples are taken regularly and analysed for numerous chemical and physical parameters in the TREND and SPEZ modules of the NAQUA National Groundwater Monitoring in order to monitor the groundwater quality.
Nitrates (NO3-), plant protection products (PPP), volatile organic compounds (VOC) and various wastewater tracers are analysed regularly in the TREND and SPEZ modules, i.e. at up to 545 monitoring sites. The analysis of basic hydrochemical parameters, and selected trace elements is limited to the 50 monitoring sites of the TREND module. It is mainly aimed at understanding the groundwater system and its hydrogeological and hydrochemical processes.
Other trace substances potentially relevant to groundwater quality are analysed in limited-term pilot studies as and when required.
