“…Human Health Risk Assessment (HHRA) is a quantitative method used to assess the potential threat of groundwater pollution to human health (Hossain and Patra, 2020;Qu et al, 2022;Xiao et al, 2022). For this method, people of different ages and genders are considered, covering children, adult females and adult males.…”

“…In general, the nitrate-nitrogen concentration in nature is usually below 10 mg/L, which is considered to be an effective indicator of anthropogenic pollution (Qu et al, 2022;Das et al, 2023). In the Tongzhou District, the NO 3 − concentration in groundwater ranges from < D.L.…”

“…Water quality is the basic guarantee for the security of water supply (Gu et al, 2018;Yin et al, 2019;Hao et al, 2020;Ravindra et al, 2023). The enriched elements in groundwater, especially toxic elements, could lower groundwater quality and pose a potential threat for human health (Dehghani et al, 2019;Zhang et al, 2021;Habibah et al, 2022;Qu et al, 2022). Thus, analyzing the hydrochemistry of polluted groundwater and identifying toxic element hazards in groundwater are essentially important for safeguarding the healthiness of human drinking water.…”

“…The threshold value of fluoride and nitrate-nitrogen concentration in drinking water are 1.0 mg/L and 10.0 mg/L, respectively. Long-term human intake of excessive fluoride and nitrate through groundwater consumption can lead to detrimental health effects, such as dental and skeletal fluorosis, as well as digestive system cancers (Hu et al, 2005;Gao et al, 2012;Xiao et al, 2015Xiao et al, , 2022Li et al, 2019;Subba Rao et al, 2021;Qu et al, 2022;Duan et al, 2023). Fluoride and nitrate concentration in groundwater is regulated by anthropogenic activities and geological factors.…”

Fluoride and nitrate enriched groundwater have potential threat for the safety of groundwater supply, which may cause the significant influence in human health and public safety, especially in the population aggregation area and the economic hub. This study focus on the high F‐ and NO3‐ concentration groundwater in Tongzhou District, Beijing, North China. A total of 36 groundwater samples are collected to analyze the hydrochemistry characteristic, elucidate genetic mechanism and evaluate the potential human health risks. The analysis results indicate: Firstly, most of sampled groundwater samples are characterized by Mg‐HCO3 and Na‐HCO3 with pH ranging from 7.19 to 8.28 and TDS with the large variation about 471–2337mg/L. The NO3− concentration in 38.89% groundwater samples and the F‐ concentration in 66.67% groundwater samples exceed the permissible limited value. Secondly, F‐ in groundwater originates predominantly from the water‐rock interaction and the fluorite dissolution, which is also regulated by cation exchange, competitive adsorption of HCO3‐, and alkaline environment. Thirdly, the effect of sewage disposal and agricultural activities have the significant effect on high NO3‐ concentration, while the high F‐ concentration is less influenced by anthropogenic activities. The alkaline environment favor nitrification being conducive to the production of NO3‐. Finally, the health risk assessment is evaluated for different group. The results reveal that the high NO3‐ and F‐ concentration groundwater would have the largest threaten to the children health. The results of this study could contribute to provide the scientific basis for the groundwater supply and human health in Tongzhou District.

“…Coal mining can damage aquifers, resulting in frequent hydraulic exchange between different aquifers. At the same time, mine drainage during coal mining increases the solutes in surface and groundwater, changing the chemical composition of normal water (Qu et al, 2022). Changes in natural land properties can also affect hydrochemistry.…”

Explore the hydrochemical characteristics of surface water (SW) and groundwater (GW) under coal mining activities and controlling factors is essential to ensure water security. This research concentrates on the Changhe River Basin (CRB). Water samples were collected from 27 sites within the CRB in May, July and December 2022. A qualitative analysis of hydrochemical characteristics and major ion sources was conducted based on Piper plots, Gibbs plots, Pearson correlation analysis and ion ratio methods. The PCA ~ RSR model was used to assess the current status of SW and GW quality in the CRB. We found that the hydrochemical type of SW and GW is HCO3- Ca, with HCO3− accounting for 62.2% ~ 87.9% of the total anions and Ca2+ accounting for 27.4% ~ 31.3% of the total cations. Rock weathering is the main factor affecting the hydrochemical of CRB. SW is affected by the weathering and dissolution of both silicate and carbonate rocks, while GW is mainly affected by the weathering and dissolution of silicate. The cation exchange also has influence on GW. The cations in the water are mainly derived from rock weathering dissolution and exchange reactions, while the SO42− in anions is mainly imported from outside. The results of the water quality assessment showed that water quality in the midstream of the study area is poor and coal mining has seriously affected water safety issues. The study reveals the impact of coal mining on hydrochemical. It provides a scientific basis for the protection and management of water resources under coal mining activities in arid and semi-arid regions.

Karst groundwater, which is one of most important drinking water sources, is vulnerable to be polluted as its closed hydraulic relation with surface water. Thus, it is very important to identify the groundwater source to control groundwater pollution. The Pearson correlation coefficient among major ions (Na + K+, Ca2+, Mg2+, HCO3−, SO42−, and Cl−) was employed to deduce the groundwater types in Zhong Liang Mountain, Southwest China. Then, the combined method of principal component analysis and cluster analysis were employed to identify the groundwater sources in a typical karst region of southwest China. The results shown that (1) the high positive correlation between cations and anions indicated the water–rock reaction of Ca‐HCO3, Ca‐SO4, (Na + K)‐Cl, and Mg‐SO4. (2) The major two principal components that would represent water–rock reaction of CaSO4 and Ca‐HCO3 would, respectively, explain 60.41% and 31.80% of groundwater information. (3) Based on the two principal components, 33 groundwater samples were clustered into eight groups through hierarchical clustering, each group has similar water–rock reaction. The findings would be employed to forecast the surge water, that was an important work for tunnel construction and operation.Practitioner Points The components of groundwater was highly correlated with water–rock reaction. The principal component analysis screens the types of groundwater. The cluster analysis identifies the groundwater sources.
