“…The negligible (almost zero) correlation between Na, Mg, and Cl confirms there was no mixing of the groundwater samples with saline water, affirming they were completely recharged by fresh water sources (e.g., ponds, creeks, streams, rivers). It is very likely to find the following correlation pairs (Na and Cl, Mg and Cl, TDS and Cl, Na and TDS, salinity and Na, Cl) in regions where salt deposits or saltwater intrusion interferes with water resource quality [40]. However, in this study, no such association was recorded.…”

“…Gibbs [38] diagram helps in establishing the relationships between water chemistry and hydrologic processes and lithology of an aquifer. Although the Gibbs diagram was originally drawn for surface water, many researchers [12,32,35,[39][40][41][42][43] have used it in groundwater studies.…”

“…The four components show that the analyzed variables have two distinct sources (anthropogenic and geogenic) influencing their occurrence and consequently the chemical composition of groundwater samples in the study area. The number of significant PC for interpretation was selected with a minimum eigenvalue of 1 [13,35,40]. In this study, component (factor) loadings of < ± 0.4 are taken to show poor loadings; ± 0.4 signifies moderate loadings and > ± 0.4 indicates high loadings.…”

“…Likewise, pH, turbidity, HCO 3 , Na, Mg, Ca, and Fe with high factor loadings in PC 3 indicate geogenic sources. The coexistence of pH and HCO 3 in PC 3 could be indicating that the latter influences the former and could also be why the majority of the groundwater samples are slightly acidic [12,40]. A further shift in the pH (toward acidity) may result in precipitation of CaCO 3 from the water [28] (Eqs.…”

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.

Groundwater is the main source of water for drinking, industrial, and irrigation uses for most nations. Groundwater quality deterioration occurs due to urban, agricultural, mining, and industrial expansions. This research deals with the assessment of groundwater quality index, correlation, clustering analysis, and major ions chemistry around Jampali opencast coal mine of Raigarh district, Chhattisgarh, India, where groundwater is the main source of drinking water. A total of 28 groundwater samples were collected from the different stations in the month of April 2019 and 11 physicochemical parameters were examined. The results of the physicochemical analysis showed that cation abundance follows the order Na + > K + > Mg 2+ > Ca 2+ in the groundwater, while anion abundance follows the order Cl − > NO 3 − > SO 4 2− > F − . A strong positive correlation is observed between TDS-EC, TDS-Mg 2+ , TDS-Na + , TDS-Cl − , TDS-SO 4 2− (r = 0.999, 0.871, 0.872, 0.846, and 0.801) and EC-Mg 2+ , EC-Na + , EC-Cl − , EC-SO 4 2− (r = 0.871, 0.873, 0.846, 0.802). The two clusters demonstrate a blended genesis connected to anthropogenic and geogenic measures. Based on calculated water quality index (WQI) values, groundwater falls under two classes: excellent and good water. WQI values of the study region depict that 85.72% of samples come under the excellent category and 14.28% in the good category.
