Abstract: The inhabitants of four communities namely, Andokope, Dadome, Melenu and Tsikpoe, in the Adidome distinct of the Volta Region depend on stream and dug-outs for their water, which are quite a distance from them. In order to improve the water supply situation as well as providing clean water for these communities in the district, the Volta Rural Water Supply and Sanitation Program (VRWSSP) decided to provide boreholes under the sponsorship of the Danish International Development Agency (DAN IDA) In view of this the VRWSSP requested the Water Resources and Research Institute (WRRI) the Council of Scientific and Industrial Research (CSIR) to conduct hydrogeological studies in the four communities. The objective of the study was to provide the district VRWSSP with sufficient data to he used in evaluating hand dug wells or borehole drilling points in these communities. The study was carried out between 4th April to 12th May, 1997. The investigations consisted of office and field work. The office work involved the acquisition and study of geological, location and topographical maps. The field work consisted of field reconnaissance and geophysical survey. In the field reconnaissance, features on the location maps were identified and confirmed. Traverse lines were also selected, cleared and pegged. The Geophysical survey carried out in the four communities involved the use of the Electromagnetic (VLF) profiling and Resistivity profiling along traverses to locate weathered or fractured zones. The Vertical electrical sounding (VES) technique was used to obtain the depth at which the fracture zones could be located. The equipment used was the ADEM, WADI, VLF system and the ABEM Terrameter SAS 300C. Data obtained by using the VLF WADI system and the ABEM Terrameter were processed with the sector and the Sondel V 0.9 software’s. In all, 11,980 m length of ground was profiled with the VLF system, and the resistivity profiling covered 5750 m. A total of 35 potential borehole sites were selected.
