Large Scale Hydrogeological Investigation In The Beder Area - A Case Study

By the integrated use of geophysical methods a ltydrogeological investigation with a very<br>high r~~solution of the geology has heen carried out in Denmark. llsing newly developed<br>methods such as auger Ellog drilling with levrl specific Water sampling and pulled array<br>contitttlous electric profiling together along with more Ouniliar techniques such as transient<br>electromagnetic sounding we have perfortned a general exantinatiott of the vulnerability,<br>the volumetric extent and the chemical properties of the aquifer itt the area. The<br>protection of the aquifer was less than expected. There was a rorrelation between the water<br>quality and the lithology of the aquifer.
