Groundwater is the most important source for the abstraction of drinking water in Germany. Water supply companies collect and store many data on the quality of the groundwater they use. Nationwide however, there is no standardized and contemporary information concerning the condition and development of groundwater quality.
The water supply companies’ information on the current chemical status situation and trends in groundwater quality in Germany are very important, as they facilitate an early recognition of developments (early warning system). Furthermore such information can contribute to identify problematic areas and regions and can provide the scientific basis for the work of associations concerning the protection of source waters.
Within this feasibility study the frame conditions for the development and establishment of a nationwide groundwater database were identified and discussed. In a first working step, existing database-concepts and structures were collected and examined. In the second step, possible participants, users and supporters of a nationwide database were identified. Based on these results a concept for a nationwide database was described. Important aspects were attempts for a successful realisation. Furthermore possible applications and functions of such a database were presented.
