“…Fluoride is crucial for maintaining human health by helping prevent dental caries at low concentrations (Kabir et al, 2020). Nevertheless, prolonged exposure to high concentrations of uoride can lead to severe health and hygiene issues, a scenario more commonly observed in rural areas of developing countries (Rehman et al, 2022;Xiao et al, 2022b;Li et al, 2024). A plethora of research endeavors have delved into the origins and migration patterns of high-uoride groundwater, encompassing both natural elements like topography, runoff dynamics, and aquifer constitution, and anthropogenic factors such as land usage and irrigation practices (Su et al, 2015;Ali et al, 2016;Li et al, 2019;Chen et al, 2023).…”

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

The present study was conducted out in the Upper Kebir Sub-basin [North East (NE) Algeria] aiming to evaluate the status and spatial–seasonal variability of water quality for domestic purposes using hydrogeochemical parameters and water quality indices. Surface water samples were collected from selected 27 sites, in the period 2020–2021 during both the wet and dry seasons and were analysed for 22 parameters. The findings were compared with standards and the water quality indices were calculated. The analysis revealed that the basin was mainly polluted and showed significant seasonal and spatial variations in water quality, considerably influenced by climatic conditions (surface runoff) and human activities (urban sewage and agricultural activities). The results reveal significant spatio-temporal fluctuations and highlight areas likely to be affected by anthropogenic activities.
