f Combined use of ELLOG data and borehole-to-surface DC measurements in environmental problems in Denmark

Stainless steel electrodes were placed in 3 borings at and near a waste deposit located in the city of Aarhus, eastern Jutland, Denmark. The waste deposit is situated in a glacial river valley. Drinking water for the city of Aarhus is extracted from a lower aquifer consisting of fluvial deposits of varying composition with high permeable land/gravel formations interchanging with love permeable clay, silt and fine grained sand. The aquifer is covered by 20-30m thick moraine clay that is locally disturbed by the ice. The locations of the deposit areas and borings are shown on the opposite page .
