“…The sources of Na + and SO 4 2− in samples could be inferred from the Na + /SO 4 2− plot in Figure 9k,l. Sample distribution along the y = x line was symmetrical, but still varies significantly [47]. In particular, SO 4 2− equivalent concentrations of some river water was higher than that of Na + , thus Na + and SO 4 2− may be strongly affected by human activities [10].…”

“…The ionic ratios can reflect the dissolution of different minerals produces different types or ratios of ions, and further help analyze the effects of the dissolution of different minerals on groundwater chemistry [47]. In order to further explore the ionic ratios of dissolved minerals, this study mapped the Scatter plots of major ions (Figure 9).…”

“…Groundwater samples were mainly affected by evaporation, while a few groundwater samples in the transition zone and the mountainous areas were controlled by the dissolution of carbonate (Figure 9b). The silicate weathering or a cation exchange can reflected by the Na + /Cl − ratio [45,47]. The ratio of (Ca 2+ + Mg 2+ )/(HCO 3 − + SO 4 2− ) can reflect the calcite weathering.…”

Water environment monitoring is an important way to optimize the allocation and sustainable utilization of regional water resources and is beneficial for ensuring the security of regional water resources. In order to explore hydrochemical distributions in a mountain–oasis ecosystem in Central Asia, surface water and groundwater samples from the Kaidu River basin were collected over four seasons. pH values, major ions, total dissolved solids (TDS) and stable isotopes were determined during the period from 2016 to 2017. The results showed: (1) that most water bodies in the study areas were mildly alkaline and that hydrochemical distributions showed significant seasonal and spatial variation; (2) that δD and δ18O in surface water and groundwater showed enrichment in summer and autumn and poverty in spring and winter, with higher δ18O values appearing in the oasis area and lower δ18O values appearing in the mountain area; (3) that most of the water bodies in the study areas were of HCO3—Ca2+ type, with the hydrochemical types of groundwater presenting obvious spatial inconsistency relative to surface water; (4) that rock weathering was the main factor controlling hydrochemical composition in the study areas and that human activities had an influence on the groundwater environment in the oasis area; (5) and that surface water–groundwater interactions also displayed spatial inconsistency, especially in summer. The interaction between river water and groundwater was more obvious in the traditional oasis area, especially in spring and summer. The results will be important for regional water resource management and sustainable water utilization.

Moreover, the hydro-geochemical properties of groundwater are the major controlling factors for groundwater quality [ 19 , 20 ]. In this regard, most straightforward approach is to compare the groundwater quality indicators to their guideline levels [ 21 , 22 ].…”

“…Any groundwater with NO 3 − concentration beyond this limit implies being impacted by anthropogenic contamination. The molar ratio diagram of NO 3 − /Na + versus SO 4 2− /Ca 2+ can demonstrate a detailed picture of the source of anthropogenic contaminants (Gao et al, 2021). As shown in Figure 7A, groundwaters at G1, G2, G5, G26, G30, and G45 were presented being contaminated by nitrate-containing fertilizers or domestic wastewater.…”

Phreatic groundwater plays a significant role in the water supply for human communities, especially in water scarce regions. This research was conducted to investigate the hydrochemistry and contamination of phreatic groundwater and their constraints on drinking water supply in a semiarid region of the North China Plain. A total of 49 phreatic groundwaters were collected for the hydrochemical analysis. The results suggested the phreatic groundwater had a slightly alkaline nature. Although the groundwater had a large variation of salinity with the TDS of 172–1,875 mg/l, most groundwater was moderately-hard fresh and of HCO3-Ca type. Contaminants of NO3−, NO2−, NH4+, Fe, F−, Zn, Mn were detected, but only NO3−, NO2−, NH4+, and Fe were found exceeding the drinking water desirable limits at some sites. The nitrogen contaminants were from anthropogenic inputs (urban sewage effluents and agricultural fertilizers) and mainly distributed in the central study area. The anthropogenic inputs of nitrogen contaminants also elevated groundwater salinity. Among the exceeding contaminants, only NO3− would pose a potential health risk to water consumers. The existing health risks by NO3− ranged from medium risk (HQ of 1–4) to high risk (hazard quotient > 4) for all populations, and most risks were categorized into the medium risk rank. Groundwater F− was also found with health risk at some sporadic sites although it did not exceed, only approached, the desirable limit. Its health risk was only to infants and categorized into the medium risk with the maximum HQ of 1.55. Most phreatic groundwater (83.67%) in the study area had relatively good quality and was suitable for domestic usage with the EWQI value below 150. Others belonged to the poor (EWQI of 150–200) and extremely poor (EWQI > 200) quality categories, and mainly distributed in the urban Gaocheng. Thus, it is recommended to pay attentions to the anthropogenic contaminants inputs into phreatic aquifers in human activities areas.
