The Danish drinking water supply will be reviewed and results from the National Groundwater monitoring programme will be shown. How to gain drinking water in Denmark and who is the one that captures the water. What types of pollutants are found in groundwater and where they exist. The various types of vandalism will be reviewed and a recent study of small private water supply plants providing individual households will also be involved in the lecture.

If some of the listeners have their own water supply system, these plants will be the starting point for a discussion with the presenter, which would like to contribute proposals for solving water quality problems in the private water supplies that are threatened by Contamination in the high-lying vulnerable aquifers, from which these plants often gain drinking water. Coliform bacteria also appear in the high ground water and these indicator parameters are not only derived from the sewer or the kloaker.

The presence of groundwater animals is a new issue in Denmark which has not previously been investigated in high-level aquifers. This is due, inter alia, to That the last ice cover only recently melted away from Denmark, that other places in the world have not found rich aquifers in similar areas, and that well-borers in Denmark have developed a construction of boreholes that prevent larger groundwater animals from Climb into the filters of the drilling.
