An integrated public information system for geology, groundwater and drinking water in Denmark

Denmark has a long tradition for having central geological databases, including a systematic collection and storage of geological and hydrological information from all surficial boreholes which was initiated in 1926. Since the mid-1970s such data have been stored digitally. A large variety of users access a central Danish, geological database: the public, for information about their local drinking water quality, environmental employees in municipalities, regions and the state for using, entering and updating data as well as consultants and drilling companies working for public administration and local water works.
