“…Hence, the identification of major hydrogeochemical facies, geochemical controlling mechanisms, and drinking suitability evaluation are essential for a complete GW quality evaluation [ 27 , 28 ]. Hydrogeochemical facies are imperative for deciphering the hydrogeochemical process and for GW quality and its trend appraisal [ 29 , 30 ]. Groundwater quality and its geochemical characteristics depend on dissolution, mineral solubility, ion exchange process, and recharge sources [ 27 , [29] , [30] , [31] ].…”

“…Investigating its spatial distribution is essential for delineating hydrogeochemical processes and flow paths in mines. Currently, a suite of established methodologies, including ion ratios, multivariate statistical analysis, isotopic tracing, hydrochemical modeling, geographic information systems (GIS), hierarchical clustering analysis (HCA), principal component analysis (PCA), and self-organizing maps (SOM), are extensively utilized to investigate the dominant factors and spatiotemporal variations of hydrochemical evolution within the multilayered aquifer systems [8][9][10][11][12][13][14][15][16][17][18][19]. Moreover, water-stable isotopes and tritium radioactive isotopes have been extensively employed to investigate the origin and age of the water [20][21][22][23][24].…”

Taiyuan Formation limestone groundwater is the main aquifer threatening the safety of exploration under deep mining in the Huaibei coalfield. Therefore, acknowledging the hydrochemical characteristics and constructing reverse hydrogeochemical modeling are crucial for predicting and preventing mine water hazards. In this study, the mathematical statistical analysis, Piper threeline diagram, Gibbs diagram, ion proportional relationship, Chlorine-Alkali index, and the reverse hydrogeochemical modeling were employed for determining the hydrochemical characteristics and the formation mechanism. The results revealed that the hydrochemical types of groundwater samples were SO 4 .Cl-Ca.Mg and HCO 3 .Cl-Na, respectively. The water-rock interactions were primarily influenced by the leaching and the cation exchange, with these processes being more intense in the eastern region. Through reverse hydrogeochemical modeling, the water-rock interactions in the process of groundwater runoff were quantitatively verified, viz. the calcite and the dolomite were saturated and precipitating, while the gypsum and the halite were unsaturated and still dissolving. Furthermore, the simulations of mass transfer in groundwater runoff indicated that the dissolution and the leaching of gypsum, dolomite and halite, positive ion exchange, the precipitation of calcite, and the dissolution of CO 2 gas predominantly occurred along four simulated flow paths. These results offered a scientific foundation for the prevention and controlling of mine water hazards in deep mining contexts.

“…Currently, global concern centers around changes in both the quantity and quality of groundwater [4][5][6]. On one hand, industrial activities contribute to groundwater pollution through the discharge of wastewater, exhaust gases, and solid waste [1,7]. Similarly, agricultural practices, such as excessive fertilizer application and pesticide residue from spraying, further deteriorate groundwater quality [8,9].…”

The evaluation of vulnerability is a crucial aspect in the sustainable development, utilization, and preservation of groundwater resources. This study utilizes a comprehensive approach, integrating systematic analysis of hydrogeological conditions and the utilization of observed and collected data. The evaluation of groundwater vulnerability in the Yishu River Basin (YRB) was conducted by employing the DRASTIC model, along with the zone overlay function of GIS software. Seven evaluation indicators were considered in this assessment. The findings demonstrate that the groundwater vulnerability in the YRB can be categorized into five divisions: excellent, good, medium, poor, and very poor, accounting for 14.5%, 42.3%, 27.9%, 14.0%, and 1.3% respectively. The areas with low vulnerability are predominantly located in the eastern part of the study area, covering the largest proportion of the total area. Conversely, areas with high vulnerability are found alongside both banks of the Shu River, forming narrow strips. Although these areas have smaller overall coverage, they contain dispersed water sources that require careful attention. These research findings provide valuable scientific insights and serve as a reference for urban planning, land use management, and groundwater resource protection in the YRB. The formulation and adoption of targeted protection measures in accordance with different groundwater vulnerability zoning, the formulation of scientific groundwater resource development and utilization programs, and execution of land resource planning are of great significance from the perspective of groundwater resource protection.
