“…Furthermore, the analysis of physicochemical parameters indicated that the areas with the highest pH generally exhibited the highest Ni concentrations. However, Pearson's statistical correlation calculation did not show a significant relationship between Ni and pH 22 . In a similar study conducted by Rezaei et al in Sistan and Baluchestan, which almost the similar climate condition to that of our study area, the concentrations of heavy metals exceeded the acceptable limits stated by the international standards, with most of the sampling locations being affected by the agricultural activities and fertilizers 28 .…”

“…USEPA suggested an acceptable concentration for Ni at 100 μg l −1 , while we found the highest Ni concentrations at 132.39 μg l −1 in Halvan station, where mining activities have increased over the last three decades. Kazemi et al stated that there is a relationship between the density of active mines and groundwater pollution, meaning that the concentrations of Ni in the groundwater of heavily mining sites are higher than the areas with fewer mines 22 . In our study area, the mean spatial distance between sampling sites which high Ni concentrations and abandoned mines were at 7.8 ± 1.79 km, and locations with the highest Ni concentrations showed the lowest spatial distance with the mines.…”

Mining activities have increased the potential risks of metal pollution to the groundwater resources in arid areas across the globe. Therefore, this study aimed to examine the health risk associated with nickel (Ni) in the groundwater sources of a mining-impacted area, South Khorasan, Eastern Iran. A total of 110 stations were included in the study, comprising 62 wells, 40 qanats, and 8 springs in summer, 2020. Initially, the collected samples were tested for temperature, pH, and electrical conductivity (EC). Subsequently, the samples were filtered and treated with nitric acid (HNO3) to measure the concentration of Ni using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Hazard quotient (HQ) and non-carcinogenic risk assessments were employed to evaluate the potential risks of Ni to the inhabitants. The findings revealed that the concentration of Ni ranged from 0.02 to 132.39 μg l−1, and only two stations exhibited Ni concentrations above the WHO standards (20 μg l−1). The results demonstrated that 98.21% of the sampled locations had HQ values below one, indicating negligible risk, while 1.78% of the stations exhibited HQ values of one or higher, representing a high non-carcinogenic risk for water consumers. Overall, the concentration of nickel in the groundwater of South Khorasan exceeded the World Health Organization (WHO) limit solely in the Halvan station, posing a non-carcinogenic risk for the residents in that area, and therefore, additional efforts should be made to provide healthier groundwater to consumers in this region.

“…Determining water quality by interpreting many parameters affecting water quality at the same time is complex and costly and takes a long time. For this reason, WQI models are used, which provide a more understandable interpretation of water quality. ,− The WQI is used to evaluate the overall quality of water and represents a single number that can be easily calculated. The WQI is a single value obtained by a quick and simple method and its corresponding.…”

Access to clean water has gained great importance, especially in urban areas, in connection with drought within the framework of climate change. This study was carried out with hydrogeochemical investigation in a district of İzmir, the 3rd largest city of Turkiye, which contains economic natural ore deposits (Sb, Hg, and Pb-Zn). The heavy metal content of groundwater has great importance in and around the ore deposits for health risk assessments (HRA) and water quality index (WQI) interpretations. Groundwater samples in the study area were taken from different units such as gneiss, marble, schist, and alluvium. The electrical conductivity of water varies between 466 and 2720 μS/cm. The waters are of NaCaHCO3 and CaNaHCO3 water types. Silicate and carbonate weathering were seen in the waters taken from gneiss/schist and marble/alluvium, respectively. Al, Ni, and Sb values of groundwater exceeded the drinking water standards. Sb concentrations can reach 967 ppb, and all waters are oversaturated with Sb(OH)3. It is thought that Sb mixes with groundwater along faults from mineralization zones. According to the WQI, the groundwater is not suitable for drinking. If the presence of ore deposits is neglected in the WQI, water that is dangerous for drinking is incorrectly considered ″drinkable″. The HRA was calculated for Al, Cu, Fe, Mn, Ni, Sb, and Zn parameters. The hazard coefficient of Sb is more than 1 for adults and children. The most striking effect of Sb compounds is that they disrupt the heart rhythm and cause irreparable damage to the nervous system.

“…By defining the link between groundwater contamination and human health using the toxicity data of the pollutants, the primary goal of health risk assessment is to determine the possible human risk level and provide recommendations for the prevention and control of pollution. This technique has been used frequently to evaluate potential negative health effects brought on by exposure of humans to polluted water 2,[30][31][32][33][34][35] . Nitrate contamination of groundwater has a detrimental effect on human health.…”

Recently, groundwater has been recognized as one of the primary sources of water supply in Sudan. However, groundwater quality continues to deteriorate due to natural and human-induced activities. This research employed groundwater quality index (GWQI), multivariate statistical methods and human health risk assessment to investigate the suitability of groundwater for domestic uses in northern Khartoum state, Sudan. The groundwater samples were analyzed for eleven physiochemical parameters, including pH, EC, TDS, TH, Cl-, SO4-2, NO3-, Ca+2, Mg+2, Na+, HCO3- and the primary investigation indicated the deviation of these parameters from World Health Organization (WHO) standards. The hydrochemical analysis revealed different groundwater facies with the dominance of Ca-Mg-HCO3 water type. Consequently, the groundwater samples were classified, based on GWQI, into three categories as 76.4 % of the samples fall in the excellent water class, 17.6 % are projected in the good water class, and 5.9 % of groundwater samples are considered unsuitable for human consumption. The multivariate statistical methods, including Pearson's correlation analysis, hierarchical cluster analysis (HCA), and principal component analyses (PCA), were applied to determine groundwater quality data's structure and the primary factors influencing groundwater quality. These techniques revealed that groundwater in the study area is mainly controlled by rock-water interaction and agricultural practice. Additionally, they were used to categorize groundwater samples based on their chemical content. As a result, three types of groundwater were identified low, medium, and highly mineralized. In the final stage, the non-carcinogenic human health risk was assessed based on the concentration of NO3- and the obtained hazard quotient for children indicated that 64.7 % of groundwater samples are beyond the permissible limit (1<) and the use of these samples may result in health consequences. As a result, remedial measures are suggested for the sustainable use of groundwater.
