“…Additionally, basic functions of a society require water for cleaning, for public health consumption, for industrial processes and cooling and for electricity generation [1]. Studies done by John [2] emphasized that groundwater plays an important role in supplying water to many of the global population for use in agriculture, drinking water, and industrial purposes. Physical and/or economic water scarcity occurs on all of the populated continents, with some parts of the world facing a genuine water crisis [3].…”

Physicochemical and Bacteriological Parameters of Borehole and Hand dug well water of Michika town in Michika Local Government Area of Adamawa State, Nigeria and environs were assessed to determine their suitability or otherwise for drinking and domestic purposes. Ten (10) water samples, five each from boreholes and hand-dug wells, from five selected areas in Michika town, were collected during the months of January and February 2018. The water samples which are extensively used for drinking and other domestic purposes, were randomly collected and the results were compared with WHO and NAFDAC standards guidelines for drinking water. These samples were analyzed for their physicochemical characteristics (pH, temperature, electrical conductivity, TDS, Turbidity, hardness), heavy metals, Escherichia coli (E. coli) and coliform counts. The results of the investigation revealed that the physicochemical and bacteriological parameters falls within the maximum permissible limits of NAFDAC and WHO guidelines for drinking water. The physicochemical concentrations were higher in borehole water than in hand dug well water; Lead and Cadmium were not detected in all the samples. All the water samples were free from feacal contamination except in Barikin Dlaka hand dug well which contained 0.05 ± 0.001 MPN/100 ml total coliform count which is below the WHO/NAFDAC maximum permissible levels. The suitability of water for domestic and drinking purposes indicated that the water samples were within the standards prescribed for potable water. However, there is need for routine checks to ascertain the suitability or otherwise of these water sources so as to forestall outbreak of water born diseases.

“…In Africa in particular, and the world in general, groundwater is considered a relatively safe and cost-effective water source compared to other water sources, especially in those regions where surface water is not readily available [15]. As such, this natural resource is facing constant decrease in quantity and deterioration in quality as a result of both natural and anthropogenic activities, a challenge that is anticipated to get even worse in the 21st century and beyond [16]. Although the limited access to clean portable water has forced many households in South Africa (and many African countries as a whole) to consider alternative sources such as rivers and streams, these sources are usually of poor microbial quality [17,18,19,20].…”

In the absence of pipe-borne water, many people in Africa, especially in rural communities, depend on alternative water sources such as wells, boreholes and rivers for household and personal hygiene. Poor maintenance and nearby pit latrines, however, lead to microbial pollution of these sources. We evaluated the abundance of Escherichia coli and the prevalence of pathogenic E. coli virulence genes in water from wells, boreholes and a river in a South African peri-urban community. Monthly samples were collected between August 2015 and November 2016. In all, 144 water samples were analysed for E. coli using the Colilert 18 system. Virulence genes (eagg, eaeA, stx1, stx2, flichH7, ST, ipaH, ibeA) were investigated using real-time polymerase chain reaction. Mean E. coli counts ranged between 0 and 443.1 Most Probable Number (MPN)/100 mL of water sample. Overall, 99.3% of samples were positive for at least one virulence gene studied, with flicH7 being the most detected gene (81/140; 57.6%) and the stx2 gene the least detected gene (8/140; 5.7%). Both intestinal and extraintestinal pathogenic E. coli genes were detected. The detection of virulence genes in these water sources suggests the presence of potentially pathogenic E. coli strains and is a public health concern.

“…In the past few decades, groundwater was heavily exploited due to drought and growth of the world’s economy and population (Llamas & Martínez-Santos, 2005 ). The world’s population is facing water crisis which is expected to worsen during the twenty-first century (Luczaj, 2016 ). In this respect, the main goal of the United Nations (UN) for sustainable development is safe drinking water; however, in many countries, the goal remains far off (Radelyuk et al, 2021 ).…”

“…The long-term heavy exploitation of groundwater induces quantity and quality deterioration of the resource. Accordingly, the major challenge facing the world is overexploitation of groundwater as well as natural and anthropogenic contaminations (Luczaj, 2016 ). Changes in groundwater compositions also result from reactions occurring along flow path (e.g., leaching of surficial salts, water–rock interaction, and/or mixing with other sources) (Sami, 1992 ).…”

This study integrates multivariate statistical analysis and hydrogeochemical modeling to investigate the processes controlling the groundwater composition of a shallow aquifer where increased pumping rates and anthropogenic impacts were prevalent. Eighteen groundwater samples were collected and analyzed for major elements and selected heavy metals. The data were classified on the basis of multivariate statistical analysis into three clusters: C1 (Na-Cl facies), C2 (Ca-SO4 facies), and C3 (Ca-HCO3 facies). The application of factor analysis gave four factors affecting the groundwater chemistry, namely the salinization factor, anthropogenic/secondary enrichment factor, the secondary and the micro-nutrient fertilizers, and the aluminum fertilizer factor. The hydrogeochemical study of the groundwater revealed that the processes controlling the groundwater chemistry in the study area are mainly affected by the groundwater occurrence either to the east or to the west of Bahr Youssef Canal. Generally, the dominant hydrogeochemical processes affecting the groundwater are silicate weathering, ion exchange, irrigation return flow, gypsum applications in soil, and evaporation. The groundwater quality evaluation shows that water quality varies from fair to excellent for drinking purposes, where the best water is located in the northern and central parts of the study area. The suitability of groundwater for irrigation was evaluated using several indices indicating that groundwater is suitable for irrigation in the northwest and western parts of the study area. As some groundwater samples lie in high salinity classes on the US Salinity diagram, it is recommended to use this water for plants with good salt tolerance under good drainage conditions. The integration between the statistical and geochemical tools helps reveal the dominant processes through data reduction and classification.
