“…After the cation exchange mentioned above, the Ca 2+ concentration can be decreased, promoting the fluorite hydrolysis process in the direction of dissolution, finally resulting in F − enrichment in groundwater. As stated in Section 2.1, Xiong'an New Area belongs to the NCP, and therefore, the mechanism for the formation of high-F − groundwater through ion exchange in the study area is consistent with the findings of Li et al [42]. The potential ion exchange processes can unfold as follows (Equations ( 1)-( 4)):…”

“…Groundwater holds significant importance in the maintenance of the ecological functions of Baiyangdian and in meeting the anticipated water demand for Xiong'an New Area. Currently, the analysis for genesis and migration patterns of high-F − groundwater in NCP has been primarily focused on regions such as Shijiazhuang city [41], Zhangjiakou region [42], Cangzhou city [43], and Hengshui city [44]. For example, F − concentration in the groundwater of Cangzhou city was up to 5.59 mg/L [45] and 0.05-9.71 mg/L in Zhangjiakou region [46].…”

While extant research has predominantly focused on elucidating the mechanisms of fluorine (F−) enrichment in groundwater within the North China Plain, the occurrence and formation mechanisms of high-F− groundwater in Xiong’an New Area remain unexplored. Consequently, 365 groundwater samples (172 from shallow groundwater, 193 from deep groundwater) were collected from Xiong’an New Area. Hydrochemical analysis, geochemical modeling, and statistical analysis were used to explore the occurrence and formation mechanisms of high-F− groundwater. The results reveal that the highest F− concentrations in shallow and deep groundwater were up to 3.22 mg/L and 1.79 mg/L, respectively. High-F− groundwater was primarily located at the eastern part of the study area. The distribution area of high-F− shallow groundwater was much greater than that of deep groundwater. F-bearing minerals dissolution and ion exchange were the principal formation mechanisms of high-F− groundwater in both shallow and deep aquifers. Moreover, competitive adsorption, evaporation, and the impacts of Ca2+ and Mg2+ dissolution equilibrium on F-bearing dissolution were crucial to the formation of high-F− groundwater in shallow aquifers. Desorption in an alkaline environment, evaporites dissolution and salt effects were vital to the formation of high-F− groundwater in deep aquifers. These findings can contribute to the support of local groundwater security and management.

“…The Na + and Cl – ions in water mainly come from the dissolution of atmospheric precipitation, silicate minerals, and evaporite minerals, and the Na + /Cl – value in atmospheric precipitation is about 0.86 . The study area is located inland and far away from the ocean, and the ratio of Na + /Cl – is affected by atmospheric precipitation.…”

Travertine deposits are formed after CO2 is degassed from deep karst water at the Huanglong Scenic Area, a World Natural Heritage Site. In recent years, various levels of eutrophication have occurred in travertine waters, resulting in large areas of algal mats that have severely affected the continued deposition of travertine and its appreciable value. The research on hydrochemical types, hydrochemical components, and pollution characteristics of surface water and groundwater in Huanglong National Scenic Area, a World Natural Heritage, is beneficial to the evaluation and management of regional water resources and landscape development. In June 2022, 14 groups of surface water and groundwater samples were collected from Huanglong. Mathematical statistics were used to analyze the water’s chemical characteristics, the Piper three-plot was used to analyze the water’s chemical types, and Gibbs and Gaillardet model were used to discuss the sources and influencing factors of main ions in surface water. The eutrophication degree of regional water was evaluated by the single factor index method. The results show that most of the groundwater in the study area belongs to weakly alkaline water. The cations are mainly Ca2+, the anions are mainly HCO3 –, and the hydrochemical type is HCO3–Ca. The major contribution of TDS comes from Ca2+ and HCO3 –. According to the analysis of water–rock model, the hydrochemical origin of surface water in the study area is mainly controlled by rock weathering, and most ions are influenced by the water–rock interaction of carbonate rocks, with the existence of reverse cation exchange. The spatial and temporal distribution characteristics of nitrogen, phosphorus, and carbon are obvious. Eutrophication evaluation showed that Huanglong was in a medium eutrophication state.

“…Both surface water and groundwater in the Cele region of South Xinjiang are in uenced by the controlling effects of rock weathering, which may be due to the unique climatic factors in South Xinjiang (Fan et al, 2021), where environmental differences in climate and evaporation are not signi cant across the regions, and the regions have similar environmental characteristics (Liu et al, 2021), and the areas sampled are largely within oases, leading to similar controlling factors in the hydrochemistry of groundwater and surface water. In contrast, surface water in the Fukang area of North Xinjiang is mainly in uenced by the controlled effects of rock weathering, which is due to the fact that the sampled areas are mainly close to the interior of the oasis, in areas with relatively good recharge runoff conditions and relatively weak evaporation, where slow runoff and more adequate water-rock interactions lead to the formation of low TDS water with dissolved ltration as the dominant factor and thus in uenced by rock weathering (Li et al, 2019); the groundwater sampling area is mainly close to the edge of the Gurbantunggut Desert, which is an intensely arid zone, and is subject to evaporative concentration control by the formation of high TDS water in areas of weak groundwater recharge, strong evaporation and shallow burial depths where evaporative concentration is the dominant factor (Jiang et al, 2022).…”

Water chemistry characterization of natural water bodies is important for the study of rational water resources utilization in arid zones. In this paper, the hydrochemical characteristics of natural water bodies in the south (Cele) and north (Fukang) parts of Xinjiang, China, during 2006-2016 were analysed. It was found that the ion content of surface water in Cele in South Xinjiang was higher than that in Fukang in North Xinjiang, while the opposite was true for groundwater ion content; there was a good correlation between TDS and each ion content, and the mineralisation of natural water bodies was controlled by Na+ and SO42-; the water chemistry types in Cele were Na+-Cl- and mixed, and those in Fukang were Ca2+-HCO3-, Na+-Cl- and mixed; the water bodies are mainly influenced by the control of rock weathering, with the groundwater in Fukang being controlled by evaporative crystallisation; the water bodies in Cele are mostly suitable for irrigation water, and the surface water in Fukang is more suitable for irrigation water compared to groundwater.
