“…Turbidity, color, taste, and odor, whether natural or man-made, influence consumer perceptions and behavior (WHO, 1997;WHO, 2011). Studies evaluating the quality of drinking water in Nigeria are on a continuum (Oyelakin et al, 2020;Ibrahim et al, 2020;Olowe et al, 2016;Foka et al, 2018;Ince et al, 2010). This is critical for highlighting the dangers of unsafe drinking water that are available and proliferating in both urban and rural communities, as well as boosting consumer confidence in safe water sources.…”

The majority of Nigerians lack access to a safe drinking water source, making sustainable and equitable access to safe drinking water a challenge. The current study was designed to evaluate the physicochemical quality of drinking water from various sources in 24 randomly selected communities throughout Abia State, Nigeria. These communities were selected from 8 Local Government Areas within the 3 senatorial zones of Abia State. Using sterile universal containers, water samples were collected from the major drinking water sources in the selected communities. On-site evaluation of the pH, electrical conductivity (EC), total dissolved solids (TDS) and temperature of the water samples was carried out using a HI9813-6 pH/EC/TDS/Temperature meter. The pH values of the water samples from all sampled communities ranged between 4.1 and 5.9, and the acidic pH levels of the water samples were not within the Nigerian Industrial Standard's (NIS) approved range of 6.5 - 8.5. Furthermore, the water sources in the selected communities were found to have ambient temperatures ranging from 25.8 - 31.8oC. The average electrical conductivity (0.04 µS/cm) and total dissolved solids (36.4 mg/L) of water samples from all senatorial zones studied were both within acceptable limits of 1000 µS/cm and 500 mg/L respectively. Although the other parameters (temperature, EC and TDS) evaluated in this study were within acceptable limits for drinking water physicochemical quality, this study emphasizes the importance of effective water treatment, safe distribution to households, and continuous monitoring and quality assessment of drinking water sources in Nigeria.

“…There are few studies reporting lead in groundwater from coastal basins of southwestern Nigeria. An assessment of drinking water quality using the Water Quality Index in Ado-Ekiti and environs, by Olowe, Oluyege [134], showed that Pb ranged from <0.001-7.0 mg/l with a mean value of 1.94 mg/l. The quality assessment of groundwater in the vicinity of dumpsites in Ifo and Lagos, Southwestern Nigeria by Majolagbe, Kasali [126], showed that Pb concentrations at Ifo were below the detection limit.…”

prolonged residence time in the aquifer and saltwater intrusion account for the variability of hydrochemistry of groundwater in coastal aquifers [1,[11][12][13][14]. The hydrochemistry of coastal aquifers of southwestern Nigeria is highly variable due to variation in geological configurations and human activities. Groundwater contamination stemming from human activities, and inadequate sewage discharge is on the rise in Nigeria [15][16][17]. Consequently, groundwater utilized for domestic uses is problematic and hence calls for scientific scrutiny. Examining hydrochemistry and groundwater quality in coastal regions is crucial to monitor and detect groundwater contaminants sources [18][19][20][21]. Groundwater quality analysis in Abeokuta South, Nigeria by Emenike, Nnaji [17] showed that water quality parameters exhibited wide variations from location to location. Sodium, magnesium, iron (++), and EC showed the most violation of drinking water quality standards. Anthropogenetic actions are escalating threat to groundwater quality and thus call for routine monitoring of groundwater in Abeokuta. Statistical and hydrochemical modelling of groundwater quality southwestern Nigeria showed a conjunctive imprint of anthropogenic and geogenic activities influencing the increasing dissolved chemical constituents in the groundwaters

“…Groundwater quality appraisals by Aribisala et al (2017); Oyedele et al (2019) among others on some selected hand-dug well, boreholes and spring water within Ado Ekiti metropolis, generated results, that were at disagreement with the permissible limit for potability set by the World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ). Olowe et al (2016) and others researched into the prevalence of water-related diseases arising from groundwater contaminations through anthropogenic activities in Nigeria and their works disabuse the conception that groundwater is impregnable to feacal coliform related contamination. The focus of this research is to study the impact of seasonal variations on well water quality especially in Ado -Ekiti metropolis as this will assist in creating awareness on groundwater quality for domestic consumption.…”

There is need to study the impact of seasonal variations on well water quality especially in Ado – Ekiti metropolis as this will assist in creating awareness on groundwater quality for domestic consumption. The quality of groundwater obtained during dry and rainy seasons from 60 privately utilized hand-dug closed wells in Ado Ekiti metropolis were assessed. Physicochemical and bacteriological investigations were carried out according to required standards. The temperature, colour, turbidity, pH, total solids, chlorides, sulphate, calcium, magnesium, nitrate, and iron, which are physico-chemical parameters of the well water samples ranged from 24.7 to 25.6 °C, 4.1 to 7.3 HU, 3.7 to 6.9 NTU, 7.3 to 7.5, 95.7 to 211.1 mg/L, 38.6 to 74.6 mg/L, 34.3 to 64.9 mg/L, 24.3 to 49.4 mg/L, 48.1 to 89.0 mg/L, 0.4 to 0.8 mg/L and 0.05 to 1.0 mg/L respectively. Despite the fact that the parameters were within the acceptable ranges, bacteriological studies showed the presence of E. coli (ranged from 19.5 to 81.6 CFU) throughout the seasons, thus, individuals who rely on groundwater for their health are exposed to disease-causing organisms. Deductions from the correlation matrix equally, demonstrated the relative dependence of the parameters on one another as they variate according to the change in weather. Mostly during the rainy seasons, higher concentrations of the physicochemical and bacteriological parameters were observed than during the dry seasons, proving that the rainy seasons aid anthropogenic activities from the surface to transmit dissolved harmful waste materials to the subsurface which eventually finds its paths into the groundwater. Improper disposal of faeces, faulty soak-pits, latrines, dumpsites and burial grounds are part of the factors that contribute to bacteriological pollutants in the groundwater source.
