“…This reflects the contribution of these components to the groundwater salinity. A strong positive correlation between Ca 2+ and SO4 Gibbs diagrams are the primary means of illustrating water-rock interactions in groundwater [33,34]. In general, the relative relationship between Na + /(Na + + Ca 2+ ), Cl − /(Cl − + HCO 3 − ), and TDS can reveal the dominant factors in the evolution of groundwater chemistry, i.e., atmospheric precipitation, rock weathering, and evaporative crystallization [35].…”

The Fengfeng mining area is in the transition zone between the North China Plain and the Taihang Mountains, and groundwater is the main source of water supply in the district. Under the combined influence of human activities and natural geological conditions, the quality of different types of groundwater varies greatly, posing a potential threat to the safety of drinking water. In this study, hydrogeochemical processes in different types of groundwater were analyzed using multivariate statistical analysis methods with ion–ratio relationships, and a groundwater quality and health risk assessment model was developed. The research findings show that the main chemical components and TDS in the groundwater have obvious spatial distribution characteristics, i.e., the content of deep karst water (DKW) in the west is significantly lower than that of shallow pore water (SPW) in the east, and the hydrochemical type has changed from HCO3–Ca to SO4–Ca. The chemical components of SPW and DKW are mainly derived from silicates and carbonates, accompanied by weathering dissolution of sulphidic minerals, especially SPW. The chemical components of the groundwater was also influenced by the cation exchange reaction and human activities. The quality of the SPW was significantly worse than that of the DKW, and the nitrates in SPW carry a high non-carcinogenic risk, especially to children. The shallow pore water is not suitable for drinking water. This study can provide guidance on the safety of drinking water in the Fengfeng coal mining area and other areas with intensive industrial, mining, and agricultural activities.

“…Currently, there is limited research on groundwater in the western karst region. The vulnerability of karst water to contamination is determined by the fragile karst environment in the northern and southern karst regions, the multiple recharge of karst water, the openness of the system, and the fragility of the karst environment [4]. The high permeability of the aquifers and the poor antifouling performance of the karst groundwater systems are key factors that make them susceptible to contamination [5,6].…”

With the substantial increase in karst groundwater pollution, the pollution caused by heavy metal migration has become one of the hottest topics. The migration characteristics of heavy metals in karst groundwater are closely related to the geological environment in which they are found. Therefore, this review focuses on the migration characteristics of heavy metals in karst groundwater in southern and northern China and highlights the effect of different environmental contexts such as atmosphere (precipitation), vegetation, soil, rock, and aquifers on the behavior of heavy metals. It also summarizes existing research methods on heavy metal migration in karst groundwater. Meanwhile, current advances and the future perspectives on karst groundwater heavy metal migration will be presented. It is hoped that this review may shed light on the study of heavy metal migration in karst areas.
