Single-Borehole Evaluation of Groundwater Availability and Quality Potential of Ituku Town on the Escarpment of Udi Cuesta

— Assessment of groundwater availability at a building project location in Ituku town to serve as source of water for the area was carried out. Initial geophysical evaluation using ABEM Signal Average System (SAS) 1000 Terrameter was made complimented by dowsing rod assessment to pin-point the location of sufficient groundwater resource. The geophysical survey measures the subsurface stratigraphy by estimating the variation in electrical properties of the geological formation which measures permeability in relation to depth. From the examinations, it was estimated that the proposed project location has sufficient water to support the costly venture of drilling of borehole to supply not just the project site owner facility but the neighborhood also. The geophysical and actual drilling of the borehole confirmed that sufficient water for Ituku town could be located at the depth of 175m below ground level. Sample test results confirm that the water is of good quality but there is the need for some form of treatment such as filtration and disinfection for its improvement before use. Physio-chemical analysis also indicates that Sodium Adsorption Ration (SAR) and percentage of Sodium Na+ are low but the Permeability Index (PI) of the location is high. Water resources professionals now have a useful baseline information on the depth and quality of water available in the area that should guide decisions on exploration and exploitation activities.
