Resumé
Data for geology, hydrogeology , and ground water chemistry have been used to evolve a preliminary ground water vulnerability map. By this type of map the possibility of ground water pollution can be predicted. The map may be of use in the land use planning and water planning.
As a test area in the ground water vulnerability project the 11 20 km2 large peninsula Djursland, in Jutland , Denmark, has been selected because of its geological, hydrogeological and chemical conditions which are representative for large areas in Denmark as well as in other countries.
By use of the geological basic data maps of Djursland a determination of the aquifer distribution , the piezometric head of each aquifer, and the inter-aquifer-flow relationships has been made.
EDP has been used to calculate and present the basic parameters necessary for the estimate of the vulnerability. The basic parameters include the following:
- total thickness of the geological deposits above the aquifers
- permeability of the deposits above the aquifers
- piezometric head
- hydraulic percolation time through the geological deposits above the aquifers
- reduction capacity and sorption capacity of layers above the aquifers.
The above-mentioned factors are combined and depicted in a ground water vulnerability map, which is preliminary verified by comparison with ground water chemistry maps, indicating the actual ground water quality.
The work has been supported financially by the EEC.
