Geophysical investigations for groundwater in the area around Bauchi town

A geophysical survey employing seismic refraction and vertical electrical sounding was carried out in parts of Bauchi town and environs, using a 12 Channel Dresser R4 Seismograph and Abem Terrameter model SAS 300B. The results indicate that the overburden (regolith) in the study area ranges from about 10m to 45m at places. This regolith was seen from the VES study to consist essentially of top soil which is silty sand, and highly weathered basement material, all underlain by fresh crystalline basement. The results of the study suggest that the area South of Grudum hill and most parts of the Barkumbo valley are the best suited for a borehole programme. -from Authors
