Distribution of Groundwater Hydrochemistry and Quality Assessment in Hutuo River Drinking Water Source Area of Shijiazhuang (North China Plain)

Water, Год журнала: 2024, Номер 16(1), С. 175 - 175

Опубликована: Янв. 3, 2024

The Hutuo River Drinking Water Source Area is an important water source of Shijiazhuang (North China Plain). Knowing the characteristics groundwater chemistry/quality essential for protection and management resources. However, there are few studies focused on chemistry evolution over drinking area. In this study, total 160 samples were collected in November 2021, spatial distribution related controlling factors analyzed using hydrological multivariate analysis. entropy-weighted quality index (EWQI) was introduced to assess quality. results show that hydrogeochemical types Ca-HCO3 (78.1%), mixed Ca-Mg-Cl (20%), Ca-Cl (1.9%) Graphical binary diagrams indicate hydrochemistry mainly controlled by water–rock interaction (i.e., rock weathering, mineral dissolution, ion exchange). Five principal components separated from component analysis represent rock–water agricultural return, redox environment, geogenic sources, utilization fertilizer, weathering aluminum silicates, dissolution carbonates, respectively. More than 70% not recommended irrigation due presence high salt content groundwater. EWQI assessment demonstrates good. outcomes study significant understanding geochemical status Area, helping policymakers protect manage

Under the Strong Influence of Human Activities: The Patterns and Controlling Factors of River Water Chemistry Changes—A Case Study of the Lower Yellow River

Water, Год журнала: 2024, Номер 16(13), С. 1886 - 1886

Опубликована: Июль 1, 2024

This study provides an in-depth analysis of the hydrochemical characteristics and their controlling factors in lower reaches Yellow River. Through water quality sampling over two hydrological periods within a year, combined with methods machine learning techniques, reveals joint impact natural human activities on spatiotemporal variations constituents. The findings indicate that River exhibits weak alkalinity (the pH is between 7 8), primary type being HCO3·SO4—Ca·Na·Mg. temporal variation constituents mainly influenced by rainfall, where nitrate levels are higher during flood season due to flushing effect whereas other show opposite pattern dilution rainfall. spatial River’s hydrochemistry primarily controlled combination Using Gibbs diagram analysis, it identified rock weathering main source ionic constituents, while agricultural fertilization, industrial emissions, domestic wastewater discharge have significant impacts Compared rivers worldwide, concentration relatively high, especially sulfate, which closely related geological basin intense middle reaches. Principal component for dry dissolution activities, followed wastewater; season, wastewater. research provide theoretical support resource management protection
