“…Vulnerability of natural sources of water such as lake, ocean and river, to pollutants and contaminants has made them not suitable for human consumption. As inaccessibility to safe and clean water continue to pose a serious danger to those living in a very complex terrain, groundwater provides a better clean water due to its natural microbiological and chemical qualities [4]. Groundwater is the water found beneath the ground surface most especially within the pore spaces or voids in the rock.…”

The integrated very low frequency of electromagnetic (VLF-EM) and vertical electrical sounding technique (VES) of electrical method were carried out to explore for groundwater resource in a very complex terrain within Akure metropolis. The VLF data was acquired at 10m interval along five traverses (TR 1 to 5). The conductive zones mapped on EM profiles and 2-D pseudo-section suspected to be fracture or localized features were further probed using a VES technique. A total number of 12 VES points were acquired to ascertain the fractured or contact zones. Relatively high conductivity is observed around the portion marked as F1, F2 and F3. VES conducted on these conductive zones acknowledged the suspected fractured or geologic contacts zone observed on the EM profiles. VES 1, 7 and 11 acquired on the conductive zones delineates both weathered and fractured layers with the resistivity values ranging from 80 to 490Ωm and 228 to 935Ωm respectively. These layers are considered to favour groundwater accumulation. VES acquired on the high resistive zones of EM profiles also showed high resistivity which may be not be prolific for groundwater development. The outcomes of this research may serve as a guide for sustainable water supply and water management plan.

“…Its exploration and exploitation have continued to remain an important issue due to its unalloyed needs. Though there are other sources of water, like streams, rivers, ponds, etc., none is as hygienic as groundwater because groundwater has an excellent natural microbiological quality and generally adequate chemical quality for most uses (Okpoli 2017). To unravel the mystery of groundwater, a detailed geophysical and hydro-geological understanding of the aquifer types and their spatial distribution are paramount in order to characterise the hydraulic zones in an area.…”

Integrated geophysical techniques were applied for groundwater exploration in a typical southwestern Nigeria basement terrain. EM-3D was primarily used to map out the precise subsurface conductive zones before adopting the recommended sounding locations with aid of Vertical Electrical Sounding (VES) technique. Hydraulic parameters were also estimated and plotted. Twenty Electromagnetic (EM) horizontal profiling and Schlumberger methods were conducted in E-W and N-S direction across the site. The points where the inflection of the raw real intersects the positive peak of the filtered real are diagnostic of major conductive zones suspected to be faults/fractures. Possible groundwater flow paths that identified as conductive zones were used in picking locations for VES deep sounding. The VES conducted on the conductive zones, which are labelled V 1, V 2, V 3 and V 4 were characterised by good aquifer resistivity values with relatively thick overburden, which are the major factors in determining the groundwater potential of an area in a typical basement complex, while those carried out on the non-conductive zones labelled V 5 and V 6 were characterised by poor indication to groundwater potential of the area.

“…It is essential for agriculture, industry and human existence. The healthy aquatic ecosystem depends on the physicochemical and biological characteristics [5]. The quality of water in any ecosystem provides significant information about the available resources for supporting life in that ecosystem.…”

Water resources are essential drinking water resource in developing cities, especially where no public water supply exists because of an insufficient infrastructure. Hydrogeochemistry of Lagos state was carried out to evaluate the ionic composition of the water. Coordinates was taken during sampling of water samples from Lekki, Ajah and Ikorodu areas. Atomic Absorption Spectrometer (AAS) was used for the geochemical analysis. The results revealed that (Ajah 1-5) to be: mixed, magnesium bicarbonate, between calcium and sodium, sodium chloride and mixed type water respectively. Lekki axis from (1-5): mixed-calcium sulphate and sodium chloride, Sodium chloride, mixed-between Sodium chloride and magnesium bicarbonate, mixed-sodium chloride and calcium sulphate and mixed type waters respectively. The dominance of cations like Na, Ca, Mg and anion SO4-as well as lower K indicates the significance of silicate weathering and agricultural sources, resistance of potassium minerals to weathering in the study area. The source for HCO3-might have been attributed from sources like atmospheric CO 2+ and soil organic materials while Cland NO3-suggested anthropogenic activities like agricultural influences. Lekki and Ikorodu surface water bodies falls within the mixed (saline and calcium sulphate)-permanently hard while Ajah falls into temporary hard water.
