“…Compared to the other clusters, there were maximum mean concentrations of anions and cations, resulting in the poor water quality. The hydrochemical facies were dominated by HCO 3 ·Cl‐Na, HCO 3 ·SO 4 ‐Na·Mg, and SO 4 ‐Na·Mg types, indicating the possible impact of anthropogenic activities (Wang et al, 2024).…”

“…The major hydrochemical types of the groundwater were HCO 3 ·Cl‐Na, HCO 3 ·Cl‐Na·Mg, and SO 4 ‐Na, indicating the contributions of evaporite and halite dissolutions as one of the main processes that determine the hydrochemistry in this zone. Previous studies have shown that groundwater near river R7 is severely polluted due to the excessive discharge of industrial wastewater and domestic sewage from Baoding City, and R9 is a wastewater reservoir (Kong et al, 2018; Wang et al, 2024; Yuan et al, 2017; Zhang, Wang, et al, 2021). The substantially elevated concentration of SO 4 2− in Zone V was most likely due to increased industrial development and groundwater overexploitation (Li et al, 2020; Liu et al, 2015).…”

“…In the cones of depression, the groundwater hydraulic gradient is inverse, resulting that most of groundwater flow moves toward the funnel zone. The groundwater depression cone is considered as the conflux center that is beneficial to form the preferential flow (Wang et al, 2024), which allows surface pollutants to rapidly migrate into the shallow aquifers. The infiltration of precipitation and surface water through the unsaturated zone and legacy sewage reservoir essentially enhanced the water‐rock interactions and the solubility capacity of salts.…”

“…Thus, the hydrochemical faces present a combination of HCO 3 ·SO 4 types. The hydrochemical evolution of shallow groundwater in this zone is a complex process that includes the surface river water infiltration, dissolution of halite and gypsum, cation exchange with the participation of Ca 2+ , mixing, and anthropogenic activities (Wang et al, 2024). Similarly, the mean chemical components in Zones V and VII were consistent with those of the inflow rivers in the corresponding areas (Figure 11e,g).…”

A comprehensive understanding of the hydrochemical evolution and spatial patterns of shallow groundwater systems is essential for water resource management and wetland ecological restoration. The Baiyangdian Wetland is one of the most concerning areas because of the development of the Xiong'an New Area. The spatial characteristics of groundwater hydrochemistry and potential controlling factors associated with hydrochemical evolution remain unclear. In this study, hydrogeochemistry together with the hierarchical cluster analysis were used to elucidate the hydrochemical processes and hydrological zoning patterns of shallow groundwater systems in the Baiyangdian Wetland, North China Plain. The results showed that hydrochemical compositions of shallow groundwater had considerable spatial variations, which was closely related to the inflow rivers hydrochemistry and the dynamics of groundwater–surface water interactions. A significant increase in SO42− concentration occurring at the cone of the depression was related to extensive pumping caused by anthropogenic activities. Anthropogenic activities were also a major factor controlling the spatial distribution patterns of shallow groundwater hydrochemistry. Ca2+, Mg2+, and SO42− in the wetland and shallow groundwater were primarily derived from carbonate and gypsum dissolution, while Na+ and Cl− originated from halite and silicate dissolution. Rock weathering predominated the geochemical evolution of shallow groundwater in conjunction with carbonate precipitation and cation exchange. The hydrochemistry of the shallow groundwater system presented distinct spatial zonation patterns that were classified into four clusters corresponding to seven subzones. In Zones I–IV, water‐rock interaction was the dominant factor controlling shallow groundwater chemistry, which was driven by the positive groundwater–surface water exchange. The coupled effects of anthropogenic activities and river infiltration and mixing caused the high levels of dissolved components in Zones V–VII. This study contributes to have a better understanding of the water cycle and hydraulic connections among different bodies, and will benefit the rational evaluation of hydrochemical evolution and wetland ecological restoration in the Baiyangdian Wetland.

The study emphasizes the critical role of irrigation in food safety, particularly in regions facing agricultural sustainability challenges. Conventional water management practices hinder a sustainable progress. The adoption of drip irrigation, delivering water directly to plant roots is proposed as a viable solution. The findings reveal a significant reduction (10-50%) in irrigation rates and increase in cotton yields. Groundwater levels impact irrigation requirements, with higher levels correlating with increased rates. Calculations highlight varying groundwater uptake and soil moisture content based on the cotton root system’s depth.
