“…On the other hand, the natural factors that determine how far a water system is contaminated include amount and chemistry of contaminants, topography, mobility of contaminants, toxicity of contaminants, rainfall intensity, hydrogeological conditions, the residence time and the reactions that occur within the aquifer, etc. (Ahamed et al 2015; Barzegar et al 2016Barzegar et al , 2018aTziritis et al 2017;Kalaivanan et al 2017;Prasanna et al 2017;Ezenwaji and Ezenweani 2018;Egbueri 2018).…”

“…Hydrogeochemistry reveals the ions distributed in water, which are pointers to its type and quality. An understanding of the geochemical components in water, as well as the physical ones, is important in determining its origin and suitability for drinking and several other purposes (Saba and Umar 2016;Tiwari et al 2017;Mostafa et al 2017;Kalaivanan et al 2017). Water quality index (WQI) depicts the influence of natural and anthropogenic activities based on several key parameters on water chemistry (Batabyal and Chakraborty 2015;Ahamed et al 2015).…”

The hydrogeochemical characteristics, water quality and health risk statuses of waters in Umunya district, southeastern Nigeria were studied, in attempt to evaluate their suitability for drinking and domestic purposes. Twelve groundwater and 3 surface water samples were analyzed for 26 physicochemical and hydrogeochemical parameters, using standard techniques. Results show that dominance of cations and anions is in the order Ca 2+ > Na + > K + > Mg 2+ and HCO 3-> Cl-> NO 3-> SO 4-, respectively. Order of dominance of the heavy metals is Pb > Zn > Fe > Ni > Mn > Cr > Ba. Eight water types were identified, with Ca-Na-HCO 3 (26.66%) and Na-Cl-HCO 3 (20%) dominating the study area. All the water types characterize five major facies. Further, the result revealed that the physical properties and chemical ionic concentrations in the waters are well below standard maximum permissible limits, although majority of the samples have pH values off the allowable limits of 6.5-8.5, classing the waters as slightly acidic. Generally, the water quality in the study area is deteriorated due to the presence of high levels of heavy metals. Water quality index results show that 46.67% of the water samples are in excellent and good categories. 13.33% are in poor water category, whereas 40% are in category unsuitable for drinking purposes. A good percentage of the waters predispose users to health risks. Stoichiometric and statistical analyses revealed that the variations in chemistry and quality of the waters are due to combined influence of human activities and geogenic processes (silicate weathering and ionic exchanges). Treatment of contaminated waters before use is, therefore, recommended.

“…In addition, water quality index (WQI) has been widely used to indicate a water quality class for drinking use [34]. Details on computation of WQI using relative weight and quality rating scale are presented in [20,[34][35][36][37][38][39][40][41][42][43][44][45].…”

The present study aimed to assess the impact of municipal solid waste dumpsite on groundwater bodies at Hyderabad, India. Leachate and groundwater samples collected through pre-and post-monsoon analyzed the physicochemical, microbiological, biological and heavy metals. The analytical data were compared with Bureau of Indian Standards (BIS) drinking water quality standards. Water quality index (WQI), heavy metal pollution indices like heavy metal evaluation index (HEI) and degree of contamination (Cd) are calculated for groundwater samples. High total dissolve solids values in leachates revealed that they were highly contaminated with organic and inorganic salts. Biological oxygen demand values indicated that dumpsite was "old and stabilized" with decreasing biodegradability from time to time. According to WQI, about 75% of the water samples identified as "Poor" category that is not suitable for neither drinking nor domestic purposes as per BIS standards. Similarly, HEI and Cd results indicated that majority of the samples are labeled with low-metal pollution status. Spatial patterns obtained through geographic information systems using inverse distance weighted interpolation technique revealed that the concentrations of various parameters are high due to increased degradation of solid wastes during rainfall, especially during the post-monsoon. The study suggested that leachates have treated prior to disposal on land, and continuous monitoring of groundwater wells is required to minimize the pollution and potential health hazards.

“…Treating (maybe by boiling) the waters before drinking should be encouraged, as this will help improve or maintain their quality. Irrigation water quality represents the fitness of water for agricultural utility [1,40]. In order to ascertain whether or not the water samples are good for irrigation purpose, a Wilcox diagram (Fig.…”

“…Groundwater resources in many countries are alternative sources of water for homes, industries, and farms, owing to the increasingly worrisome levels of contamination and pollution of surface water resources. In developing countries, access to safe water for drinking and domestic purposes by inhabitants is a major crisis governments and individuals fight against [1]. Contamination or pollution of groundwater resources is a threat to the quality and sustainability of available drinking water and public health [2,3].…”

The aim of this study was to evaluate and characterize the hydrogeochemistry and quality of groundwater (for human consumption) in Ogbaru district, southeast Nigeria. Borehole samples were subjected to physicochemical, bacteriological, hydrogeochemical, and statistical analysis. The physicochemical characteristics of the water were below standard maximum permissible limits for drinking water. Moreover, heavy metals were found in low concentrations (below their permissible limits) in all of the samples. However, majority of the samples have pH values below the allowable limits of 6.5-8.5, indicating they are slightly acidic waters. The dominance of cations and anions is in the order: Ca > Mg > Na > K and HCO 3 > Cl > NO 3 > SO 4 > PO 4 > NO 2 , respectively. Mg-Ca-HCO 3 water type dominated the area, constituting about 47.4% of the total samples. Ca-Mg-HCO 3 water type constituted about 16%; Mg-Ca-Na and Ca-Mg-Na-HCO 3 water types constituted 10.5% each, whereas Ca-Mg-Cl, Mg-Ca-Cl-NO 3 , and Ca-Mg types made up 5.2% each. The possible sources and influencers (both anthropogenic and geogenic) of the physical and chemical water quality parameters were identified by correlation and principal component analyses. Although most of the groundwater samples are of good quality based on the physicochemical properties, the presence of coliforms indicates that their quality is questionable and hence not safe for drinking. Therefore, treating them before use is recommended.
