oa Large-scale mapping of aquifers in the county of Aarhus using geophysical methods

Increasing problems with water quality have made ground water a very important issue in Denmark. In 1995 the Minister of Environment decided a 10-subjects scheme to improve ground water protection. One of the major issues is that all pesticides that can pollute the ground water should be forbidden. Another major issue is that counties in Denmark by the end of 1997 should be classified into 3 types of recharge areas. The classification includes: - Recharge areas of great drinking water interest, - Recharge areas of drinking water interest and - Recharge areas of limited drinking water interest The clasciffication is based on a comprehensive evaluation of the size and quality of the ground water resource. The new ground water resource plan provides guide-lines for the protection of the ground water in the county.
