“…The HPI is also a risk assessment method that considers the composite effects of individual heavy metal on the overall water quality and suitability for drinking. Many researchers (Horton 1965;Brown et al 1970;Edet and Offiong 2002;Odukoya and Abimbola 2010;Herojeet et al 2015;Wagh et al 2018;Egbueri 2018Egbueri , 2020a have successfully employed HPI extensively in determining the overall quality of water based on heavy metal concentrations. The NIS (2007) drinking water quality standards were used for the…”

“…The PCA was also used to study the interrelationships between analyzed parameters and their factor loadings (Egbueri 2018(Egbueri , 2019a. The degree of the impact of heavy metals on non-carcinogenic and carcinogenic health risk parameters and WQI was also analyzed using the PCA.…”

“…Furthermore, studies have shown that heavy metal pollution in water resources is also attributed to many other anthropogenic factors, including the overuse of chemical fertilizers and pesticides, untreated industrial wastes, poor management of open dumpsites, etc. (Bhuiyan et al 2010;Belkhiri et al 2017;Egbueri 2018Egbueri , 2019aEgbueri , b, 2020aUkah et al 2019). When these various processes release trace elements into water systems, another important factor that determines the impact such metals have on the quality of water is solubility.…”

“…These trace elements enter water systems through many natural processes and anthropogenic activities (Wagh et al 2018; Barzegar et al 2018;Egbueri 2018Egbueri , 2019aEzugwu et al 2019;Mgbenu and Egbueri 2019). The natural processes that contribute to high concentration of heavy metals in waters include weathering of rocks and soils, decomposition of living matter, and atmospheric fall-out, whereas the anthropogenic activities encompass mining (which can lead to acid mine drainage) and mineral processing, domestic, agricultural and industrial wastes, etc.…”

This paper quantified the level of heavy metals contamination, identified possible sources of pollution, and assessed the human health risks associated with drinking water resources in Ojoto Province, Nigeria. The study's gross findings revealed that the suitability of some water sources for consumption purposes in this province is questionable. Based on water quality index, 57.14% of the total samples are within acceptable limits, while 42.86% are unsuitable for drinking. It was observed that the northwestern and southern parts of the study area have more of deteriorated water quality. The health hazard index revealed that 25% of the samples predispose their consumers (both adult and children populations) to high chronic health risks. Moreover, heavy metal pollution index, contamination index, and probability of cancer risk (CR) revealed that about 25% of the total samples were unsuitable and off the CR standard acceptable range of ≤ 1 × 10 −6-1 × 10 −4. Correlation and component factor analyses linked the origin of major ions to geogenic processes and that of the heavy metals to both natural and anthropogenic processes. Cluster analysis divided the samples into two equal classes (50% each): poor and excellent quality waters. This study indicated that Pb is the priority pollutant impacting the water quality. The various assessments revealed that waters from hand-dug wells and deeper boreholes are the least contaminated and hence best suited for drinking than waters from springs, streams, and shallow wells.

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.
