| dc.description.abstract | Resistivity Profiling and Vertical Electrical Sounding (VES) using McOhm Resistivity meter was carried out in seventeen communities in Adansi North District of Ashanti Region of Ghana. Dipole- Dipole array with 20 m chainage interval was employed for the profiling; stations which had low resistivities were noted and probed further to a depth of about 70 or sometimes 80 m using VES. Points with low resistivities along profiles were interpreted to be due to groundwater, clays, weathered zones or fractures whereas high resistivities may be dike-like structures or boulders. The interpretations of the VES results revealed that most of the communities were underlain by an overburden of thickness between 12 and 16 m. Moderately weathered material ranging from less than one meter to several meters in thickness separate the overburden from the underlying weathered and fractured bedrock and subsequently hard bedrock. The bedrock may be associated with fractures in some of the communities. Recommendations for test drilling at each site was based on ascending order with low resistive points selected first. Borehole yields ranged between 17 and 150 lpm with an average of 38 lpm. Average borehole depth and static water level were 48 and 8 m respectively. Out of the 36 holes drilled 23 were successful whiles 13 were dry wells giving a success rate of 64 %. | en_US |
