Groundwater is essential for water resources, serving as a key drinking source in China. It supports daily needs urban and rural residents, aids development, maintains ecological balance. This study conducted sampling survey of groundwater the Wen River basin (WRB), assessing hydrochemical features, genesis mechanisms, quality, health risks. The findings reveal that WRB weakly alkaline, with an average total dissolved solids (TDS) concentration 755.24 mg/L. Freshwater constitutes approximately 81.48% groundwater, following order cations: Ca2+ > Na+ Mg2+ K+, anions: HCO3− SO42− NO3− Cl−. predominant types are SO4·Cl-Ca·Mg HCO3-Ca·Mg. chemical composition primarily influenced by silicate rock weathering, dissolution processes, cation exchange, human activities.

Nitrate pollution is widespread environmental concern in most shallow groundwater systems. This study conducts a comprehensive investigation of groundwater, deep and surface water region the Chinese Loess Plateau. this area severe with more than half samples exceeding limit nitrate for drinking (50 mg/L). Temporal variation reveals continued increase although fertilizer use has been reduced, recently. Spatially, much lower that supporting anthropogenic origin from surface. The intrinsic vulnerability index indicates less susceptibility loess aquifer to comparison alluvial aquifer. However, high levels are observed both aquifers. risk assessment combined loads explains occurrence precisely. Agricultural inputs release sewage-effluents major contributions hydrogeochemical evidence. aquifer, which supposed be susceptible contamination, non-negligible factor. Control long-standing issue will require sustained monitoring.

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 critical resource for economic growth and livelihoods in the dense agricultural plains of plateaus. However, contaminations from various sources pose significant threats to groundwater quality. Understanding contamination mechanisms hydrochemical control essential sustainable development agriculturally intensive plains. This research utilizes 23 datasets chemical measurements apply hierarchical clustering analysis, positive matrix factorization, analysis techniques. Through these methods, study identifies deciphers within representative plain region Yungui Plateau. The finds indicate that primarily derives rainfall occurred surrounding mountains. During long underground flow process, undergoes water-rock interactions ion exchanges with lithological strata, resulting formation distinct types. As it traverses regions influenced by human activities, encounters varying levels types contamination. Consequently, there notable variation quality across different areas plain. dominated faces HCO
