“…These indicate that rock weathering is the main contributor of major ionic species in groundwater with minor impute from precipitation. Ayogu et al, (2020), Okogbue (2012), reached similar conclusions. Furthermore, in the ionic ratio plots for surface water, the plot for Ca 2+ +Mg 2+ versus SO4 2-+HCO3shows plotted points are below the 1:1 line (Figure 5ii-a), indicating silicate weathering.…”

“…The low concentration of major ions may be a result of adsorption ions to clay-rich layers. Elevated concentration of SO 4 2and Clcan be attributed to leaching of salts (NaCl, CaCl 2 and MgCl 2 ), (Ayogu et al, 2020, Dinka et al, 2015, while Okogbue et al (2012) trace their source to anthropogenic activities (agriculture and domestic wastes). High concentration of SO 4 2can be because it more mobile than other ions in water.…”

The water sources in parts of the River Mamu sub-Basin, southeastern Nigeria were evaluated for domestic and agricultural purposes using hydrogeology and water quality. Thirty water samples from both surface water and groundwater were collected and analysed for hydrochemical and biological parameters. The average depth to aquifers and their thicknesses are 109.9 and 11.8m respectively. The concentration of the major ions, TDS and EC are within the WHO permissible guidelines for drinking water. Heavy metals concentration range in mg/L for Cd 2+ (0 -0.06), Cr 3+ (0 -0.19), Hg 2+ (0 -1.0), As 3+ (0 -0.14) and total Fe (0 -2.4) which in some of the samples exceed the permissible guideline values. The fecal coliform range in 100ml/L of samples (0 -36) exceeds the guideline values in some of the samples. The water is Ca-Mg -Cl-SO 4 type with the dominant ions as Ca 2+ and SO 4 2for both groundwater and surface water. The dominant geochemical processes are rockwater interaction in groundwater, which is a major contributor of dissolved ions and precipitation in the surface water. The WQI (17.84-301.99) connotes some samples are of very poor quality for domestic purposes. Irrigation indices depict most of the water as good to excellent for agriculture.

“…Heavy metals such as Mn, Fe, Cd, As, Pb, Ni, and Cr, which are metalloids, transition metals, basic metals, lanthanides, and actinides with specific gravity > 5.0, are known to be toxic and harmful to the environment, including surface and groundwater sources, and could be carcinogenic when ingested by human beings (Nriagu 1989;Nwigwe 2008;Nagaiyoti et al 2010;Omaka et al 2017). Because heavy metals in water sources have a high potential to cause health problems, monitoring water quality and its influencing variables is essential for water resource management and sustainability across the world (Onyekuru et al 2010;Okogbue et al 2012;Pawari and Gawande 2015).…”

The concentrations of heavy metals and health risks associated with the consumption of domestic water sources around a dumpsite in Enugu (southeastern Nigeria) were assessed by atomic absorption spectrophotometry and multivariate analysis. The results showed the dumpsite leachate mean pH value of 4.1, Mn+ of 11.4 µg/l, Fe3+ 4.1 µg/l, Cd+ 0.3, As+ 6.03 µg/l, Pb+ 2.47 µg/l, Ni+ 14.13 µg/l, and Cr3+ 1.48. The groundwater and surface water samples had mean heavy metal values as follows: Mn+ 5.23 and 0.75 µg/l, Fe3+ 1.49 and 0.15 µg/l, Cd+ 0.08 and 0.10 µg/l, As+ 1.90 and 0.15 µg/l, Pb+ 1.01 and 0.35 µg/l, Ni+ 0.37 and 0.05 µg/l, and Cr3+ 0.03 and 0.05 µg/l, respectively. Comparison with maximum permissible limits indicated that the mean heavy metal concentrations of the tested samples were lower than the limits for drinking water, except for Mn+, As+, and Pb + , which were marginal above recommended limits. Principal component analysis results showed two principal components with the first principal component having high loadings of Mn+, Fe3+, As+, Pb+, Ni+, and Cr3+, which are statistically correlated. Probable sources of these contaminants include automobile parts and tools, batteries and electrical appliances and electronics heaped at the dumpsite. Analysis of variance results indicates a significant difference in datasets between and within each and both water sources. Human health risk assessment indices indicated that the water sources are moderate to highly polluted and could pose both non-carcinogenic and carcinogenic threats when consumed untreated, with children being more exposed than adults.

“…The need to evaluate the groundwater quality of the area for domestic and agricultural uses cannot be overemphasized. There are a number of works relating to hydrochemical characteristics and evaluation of shallow groundwater in a typical rural setting (Tijani and Abimbola 2003, Al-ahmadi and EL-Fiky 2009, Okogbue et al, 2012, Talabi and Tijani 2013, Ahamed et al 2013. This study, therefore is aimed at understanding the hydrochemical characteristics and evaluating the quality of the shallow groundwater system in Gboloko area.…”

Physiochemical assessment of shallow groundwater in Gboloko area was carried out to determine its suitability for drinking and irrigation purposes. Eighteen (18) groundwater samples were collected from different rural communities' wells and subjected field measurements of physical parameters followed by chemical analyses using ICP-MS, ICP-ES, Calorimetry and Turbimetry methods. The results show that pH of the groundwater ranged from 5.1 to 8.6 (mean 6.6) which indicates the groundwater is slightly acidic and slightly alkaline. EC and TDS varied from 60 to1367mg/L (mean 277.4mg/L) and 53 to 995mg/L (mean 206.5mg/L) respectively. The concentration of major cations were in the order of Ca 2+ >Na + > Mg 2+ > K + while that of anion were in the order of HCO 3 ->Cl -> SO 4 -> NO 3 -.Five hydrochemical facies were delineated from Piper plot; they are CaHCO 3, CaNaHCO 3 , CaMgCl, CaCl, and NaHCO 3 water type. CaHCO 3 water is the dominant facies which represents water of recharge zone while CaNaHCO3 and CaCl are the least. The presence of NaHCO3 CaNaHCO3, and CaMgCl water type shows hydrochemical processes such as ion exchange and linear mixing. The drinking water quality assessment indicates the values for all the hydrochemical parameters are within the maximum permissible standard by WHO, 2006 except for two locations where nitrate concentrations are above the guideline value. The nitrate contamination observed at those locations may be attributed to leachates from domestic wastes and agricultural activities. Although nitrate contamination was expected to be rampant in groundwater of the area Irrigation water quality indices showed that the groundwater is ranged from mostly suitable to unsuitable.
