Abstract Groundwater is the critical resource for agricultural, industrial, and urban-rural water supplies in arid semi-arid regions, especially North China Plain. In this study, 64 groundwater samples were collected to assess potential development utilization upper reaches of Zhang Wei river. The hydrochemical analysis revealed that primarily composed HCO3-Ca HCO3-Na·Ca. type influenced by natural water-rock interactions, including evaporite dissolution, silicate weathering, ion exchange processes. Isotope data hydrogen oxygen, characterized positive deviations from global meteoric line, underscore significant impact evaporation region. An entropy weight index method was employed quality evaluation, revealing over 89% complied with Class II standards household use. Furthermore, more than 85% area’s exhibited Total Dissolved Solids (TDS) concentrations below 1,000 mg/L, indicating a predominance soft water. However, toxic elements such as fluorine (F), iodine (I), chromium (Cr) found exceed drinking standards, posing health risk. Particularly, intake level above permissible value, potentially causing non-carcinogenic risks children infants. conclusion, while overall favorable region, presence geochemically derived substances necessitates careful consideration its suitability purposes.

Both over-exploitation and exploitation reduction of groundwater can alter the conditions recharge discharge, thereby impacting overall quality groundwater. This study utilizes hydrogeochemical methods statistical analysis to explore spatial temporal evolution characteristics influencing factors chemistry in saline-freshwater funnel area Hengshui City under reduction. The results showed that: With exception deep freshwater western region, which exhibits a trend water deterioration (Cl− accounted for more than 25%), other areas demonstrates an improving (HCO $$_{3}^{-}$$ 25%). origins hydrochemical components two types are influenced by rock weathering. Only shallow saline eastern region is impacted evaporation. And hydraulic play distinct role controlling different areas. It mainly manifested changing water-rock reaction speed diluting ion concentration area.

Groundwater is a crucial water source and strategic resource, essential for sustaining both urban rural livelihoods, supporting economic social development, maintaining ecological balance. This study investigates the hydrochemical properties controlling factors of groundwater in Baiquan basin (BQB) by analyzing quality data collected during dry wet periods. Additionally, suitability drinking agricultural irrigation was evaluated. The findings reveal that BQB generally weakly alkaline primarily consists hard-fresh water. Although there are seasonal variations main ion concentrations, HCO 3 − Ca 2+ predominant anions cations, respectively. Consequently, type mainly -Ca⋅Mg type, with secondary classification SO 4 ⋅Cl-Ca ⋅ Mg. composition influenced dissolution carbonate silicate minerals, as well cation exchange processes. it affected anthropogenic inputs, particularly from use fertilizers. assessment results indicated all samples classified either good or moderate, significant majority falling into category. northern section exhibited lower entropy weight index (EWQI) values season comparison to season. For irrigated agriculture, serves high-quality throughout rainy seasons. Furthermore, non-carcinogenic risks notably concentrated north-western south-eastern regions area. Health associated nitrates elevated Notably, infants were significantly high across seasons substantially exceeded those children adults. These provide valuable scientific insights management development resources BQB.

Due to extensive groundwater exploitation, a funnel has persisted in the Hutuo River alluvial fan Shijiazhuang since 1980s, lasting nearly 40 years and significantly impacting chemical characteristics. In this study, based on level chemistry data, hydrochemical evolution processes mechanisms of during 1980 period post-2015 artificial governance were investigated using traditional hydrogeochemical methods inverse simulations. The results show following: (1) ion concentrations gradually increased along flow path, where they displayed pattern lower levels northwest higher southeast. From 2021, major ions increased. (2) type predominantly exhibited HCO3—Ca. 2015, types diversified into HCO3·Cl—Ca, HCO3—Ca·Mg, HCO3·SO4—Ca types. Following governance, rise led an increase SO42− Mg2+. Post-2015, prevailing changed HCO3·SO4—Ca·Mg. (3) changes quantitatively strongly correlated spatial similarity. (4) composition was primarily controlled by dissolution albite, dolomite, halite, quartz; reverse cation exchange; exploitation. Since mainly been influenced calcite, positive river–groundwater mixing; industrial activities, with increasing intensities both water–rock interactions human activities.
