“…According to Rao and Nageswararao [41], the suitability of WQI values for human consumption was applied in this investigation, as shown in Table 2. Permeability Index (PI), Magnesium ratio (MR), Kelly ratio (KR), percent Na, salinity hazard utilizing EC values, sodium absorption ratio (SAR), and residual sodium carbonate (RSC) in meq/l were calculated for irrigation purposes using equations ( 15)- (20), and the results were rated with standard values [23,53].…”

Groundwater exploitation requires better understanding of the resource availability and quality/vulnerability. Geophysical techniques, pumping test, hydraulic measurement, borehole logging and quality test analysis have been used in Ibulesoro, southwestern Nigeria, to understanding the hydrogeological system in terms of groundwater availability, aquifer delineation, and evaluate the groundwater physico-chemical and biological contents. The study utilized multi-criteria evaluation techniques (GWPIV) to assess the overall aquifer potential/vulnerability. The geology of the area comprises granite, migmatite, migmatite gneiss, biotitic granite, and gneiss. The main water-bearing unit was the weathered layer and fractured basement, which are usually unconfined aquifer. The hydraulic conductivity and formation factor is related by y = 0.239e0.0519x with correlation coefficient of 0.0961. The average hydraulic conductivity and transmissivity are 0.52 m/d and 5.78 m2/d respectively. The hydrogeological parameters viability increases southwardly, just as groundwater movement/flow is due south. The average thickness of the weathered layer and overburden are 8.6 m and 16.1 m respectively, with dominant resistivity in the range of 80 – 200 ohm-m. The best drilling points (migmatite/gneiss geologic units) are where the fractured basement underlies the weathered layer which most not necessarily exceed 30 - 35 m. The average depth to fresh basement rock is 16.1 m. The obtained GWPIV varied from 1.12 to 1.71, with an average of 1.30 suggesting low potential but good for drinking and irrigation uses in its present state, however highly vulnerability to contamination, as the vadose zone thickness (5.68 m avg.), AVI (0.57 avg.), and LC (0.0818 mhos avg.) all point to the low protective capability. The water types is mixed Ca-Mg-Cl. The mechanism controlling the groundwater quality falls in the mixed zone, which indicates contribution from soil/rock-water interaction, precipitation, and evaporation; while carbonic weathering is more active than the silicate weathering process.

“…The majorities of the samples are represented in Class I and Class II, which represents good and moderate category respectively and rest of them were not suitable for irrigational purpose. RSC is an important parameter to evaluate the suitability of irrigation water [32,43]. The RSC values in the ground water sample range from −3.60 to 0.02 (av.…”

“…This study therefore seeks to assess variations in groundwater quality in Ese Odo local government area of Ondo State, southwestern Nigeria for domestic and irrigation uses. Irrigation water evaluation is placed on the chemical and physical characteristics [32][33][34][35][36]. In agriculture, if there's good quality water, it will give sustainable yield.…”

An assessment of the ground water quality was carried out in Ese Odo local government area of Ondo State, southwestern Nigeria. The study was aimed at examining the various samples of ground water and the quality of the ground water as it relates to drinking and irrigation purposes. Forty-Five ground water samples were taken from boreholes and open wells and analyzed for physical, chemical and biological properties. The results were compared with World Health Organization standards. The usefulness of these parameters in predicting ground water quality characteristics were studied and water quality index was determined from these parameters. In assessing the water for irrigation uses, indices such as percent (%Na), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), permeability index (PI), Kelly’s ratio (KR), magnesium ratio (MR), equivalent salinity concentration (ESC) and Wilcox plot were used. The result obtained shows that the water studied has a mean value of 2.8 NTU for turbidity, 7.3 for pH, 294 μS/cm for electrical conductivity, 52mg/L for total dissolved solids, temperature 28.3°C, total hardness 41 mg/L, chloride 38.3 mg/L, calcium 15.8 mg/L, 5.64 mg/L for magnesium, nitrate 1.47mg/L, sulphate 51.7 mg/L, bicarbonate 15mg/L. Zinc, iron, manganese have mean values less than 1mg/L. The results indicated all the physicochemical parameters are within the recommended levels set by World Health Organization (WHO). Although traces of heavy metal and mineral oil contaminations are observed some of the samples. All the samples are plotted on the “Excellent irrigation class” of Wilcox plot with good/excellent irrigation indices. Consequently, the groundwater in the study area is good and suitable for drinking and irrigation purposes.
