“…The primary alteration minerals controlling the concentrations of Mg 2+ in neutral to alkaline geothermal waters are chlorites and saponites (Guo et al, 2019). Thus, the tight correspondence between mainly ions and rocks, which was widely perceived as the link connecting between geochemistry and hydrochemistry, could be used to identify the sources of groundwater (Zhong et al, 2022).…”

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.

“…Water safety is critical to human existence [1][2][3][4]. Groundwater is frequently employed in industrial and agricultural production because of its steady water supply and generally acceptable water quality [4][5][6][7][8]. Groundwater has traditionally been used as a primary source of water, particularly in locations where rivers and lakes are underdeveloped [9][10][11].…”

Groundwater is vital to local human life and agricultural irrigation, and the quality of the water is critical to human health. As a result, it is critical to investigate the hydrochemical evolution and water quality of groundwater in the Sanjiang Plain. There were 259 samples obtained. Furthermore, hydrogeochemical simulation was performed to highlight groundwater’s hydrochemical features, evolution process, and water quality. The analytical results show that the groundwater in the study area is somewhat alkaline with a mean TDS of 285.94 mgL−1 and the primary contributing ions being Ca2+ and HCO3−. The closer the concentration of TDS and NO3− is to the city, the higher the concentration, indicating that the chemical composition of the water body has been affected by certain human activities. The Piper diagram, Gibbs diagram, and correlation analysis results demonstrate that the chemical type of groundwater is mostly HCO3-Ca and the hydrochemistry is primarily regulated by weathering and carbonate and silicate dissolution. According to the entropy-weighted water quality index, the groundwater quality in this location is pretty acceptable. This study could help strengthen groundwater quality monitoring based on local conditions, identify the source of nitrate, provide data support for the safe use of local water resources, and serve as a reference for global water chemical evolution and water quality evaluation in cold regions.

“…Groundwater quality and its processes can be assessed over time and space using hydrogeochemical analysis. According to the hydrogeochemical analysis technology, Piper three-line diagram and Gibbs diagram are used to identify the evolution of the chemical composition of groundwater (Li et al, 2020;Zhong et al, 2022). These analytical methods have been extensively used to evaluate groundwater quality and hydrogeochemical changes of pollutants, such as fluoride (Qiu et al, 2023), nitrate (Li et al, 2023), and trace elements (Bodrud-Doza et al, 2019;Aithani et al, 2020).…”

As one of China's nine border provinces, Jilin Province is an important window for China's “Belt and Road” to open up to the north, and an important channel for China's foreign trade and foreign exchanges. Therefore, understanding hydrogeochemical characteristics is very important for effective water resources management in Jilin Province. A total of 64 groundwater samples were collected from 32 monitoring Wells in Jilin Province. Use of hydrogeochemical analysis techniques, WQI index and human health risk index methods to assess hydrogeochemical processes and groundwater quality, including the determination of hydrogeochemical parameters, conventional ions, trace elements and stable isotopes (δD and δ18O). The results show that the groundwater is slightly alkaline, the cations are mainly Na+, Ca2+, Mg2+, and K+, and the anions are mainly HCO3-, Cl−, and SO42-. Most of the groundwater samples belong to Ca-HCO3 and Na-HCO3 types, which are formed by the dissolution of calcite, dolomite, gypsum, silicates and carbonates. Stable isotope analysis shows that groundwater recharge in Jilin mainly comes from atmospheric precipitation at an altitude of 1,430~2,348 m. The strong correlation between trace elements indicates a common source. Most of the groundwater quality index (WQI) in the study area is Class I to Class III, and hazard quotient (HQ) and hazard index (HI) are both below 1. This indicates excellent water quality and minimal health risks associated with human consumption. It is worth noting that trace elements are enriched in the Tanlu fault zone. It provides scientific guidance for the utilization and allocation of groundwater resources in Jilin Province.
