“…This method has been used for the evaluation of groundwater quality. Strong correlations between major ions are also reported by Miao et al [40]. This situation evidenced that the groundwater quality of a coastal city in China was affected by various factors, such as dissolution and water evaporation.…”

Groundwater is an important source of fresh water in the world. However, the excessive extraction and increasing pollution represent a major challenge for water sustainability in Mexico. Nowadays, since water quality changes in aquifers are not noticeable, aquifer monitoring and assessment are imperious. In this study, the water quality of the Cuernavaca aquifer was evaluated using a database of 23 parameters in 4 sampling points from 2012 to 2019. The spatial behavior of water quality variables was described by using interpolation. The temporal evaluation of groundwater quality was carried out through time series. Water quality indices (WQI) were obtained in this aquifer and the WQI values suggest that the groundwater could be considered as good quality for potable use and of medium-high quality for irrigation. The chemical characteristics of the groundwater were also evaluated using Gibb, Piper, and Schoeller diagrams. Finally, with a total of 34 samples of each parameter in each sampling site, a multivariate statistical analysis was performed using a Pearson correlation and hierarchical cluster analysis. This analysis showed a correlation between hydrochemical features and groundwater quality parameters, where nitrates presented the highest number of significant correlations with other parameters. These results may be useful for the authorities to adopt planning methods to improve the sustainable development of the aquifer.

“…Classifying hydrochemical types can provide a more intuitive analysis of the chemical characteristics of water bodies in different basins. By using the Piper ternary diagram and the Shukarev classification method [36], comparisons of the main ion concentrations in the five watersheds were conducted, leading to the categorization of hydrochemical types (Figure 5 and Table 1). It can be observed that the proportions of each ion's concentration in river water and groundwater are similar, while the concentration of Cl − is higher in lake water.…”

“…The absence of lake water samples in the Gibbs diagram of the Golmud River is due to a TDS that exceeds 10 5 mg/L, indicating that the lake water is influenced by other factors. In the case of the Bayin River, one water sample in the summer groundwater falls outside the graph in the Cl − /(Cl − + HCO3 − ) ratio diagram, suggesting that hydrochemical characteristics may be influenced by other factors, such as human activities [36].…”

In the context of climate change, precipitation and runoff in the arid inland basins of northwest China have undergone significant changes. The Qaidam Basin (QB) is a typical highland arid inland area. Understanding the spatial and temporal variations in surface water and groundwater chemistry and isotopes, as well as their causes, is crucial for future water resource management and ecological protection. Samples of river, lake, and groundwater, as well as others, were collected and tested in five typical watersheds in the summer and winter. The hydrochemistry and isotopic spatiotemporal differences in various water bodies were studied using the significant difference method, water vapor flux models, hydrochemistry, isotopes, and other methods for cause analyses. The results indicate the following: (1) There are differences in hydrochemistry between the southern and northern basins because the southern basin is more influenced by the dissolution of salt rocks and evaporation, whereas the northern basin is mainly affected by carbonate weathering. (2) The enrichment of δD and δ18O in the northern basin gradually increases from west to east, while in the southern basin, it is the opposite. This is because the southern basin receives a larger contribution of water vapor from the mid-latitude westerlies, while the northern basin primarily relies on local evaporation as its water vapor source. (3) Significant differences are observed in the total dissolved solids (TDS) and hydrochemical types of river water and groundwater between the summer and winter due to higher rates of rock weathering and evaporation in the summer. (4) The more pronounced seasonal differences in hydrogen and oxygen stable isotopes in the southern basin are due to higher rates of internal water vapor circulation in the summer. (5) The similarity in characteristics between river water and groundwater is the result of strong exchanges between river water and groundwater from piedmonts to terminals. The spatiotemporal heterogeneity of terminal lakes is attributed to the accumulation of salts and groundwater replenishment from other sources.

“…The coastal regions adjoining seawater environments typically featured the presence of Cl − −Na + ions. 26 Given these circumstances, PFOA, in conjunction with various ions, is prone to infiltrating both soil and groundwater, thereby engendering diverse PFOA-ion occurrence environments. However, the attenuation mechanism governing PFOA within the context of various PFOA-ion occurrence environments, specifically in conjunction with microbe−mineral interactions, remains unclear.…”

The coexistence of iron−sulfur minerals (Fe x S y ) and microorganisms is a common phenomenon, often leading to intricate interactions. Perfluorooctanoic acid (PFOA) presents extensive spatial−temporal attenuation characteristics. However, the mechanism governing PFOA in relevant diverse PFOA-ion occurrence environments remains unclear. In this study, the effects difference between microbe/Fe x S y and microbe−Fe x S y , and specific effects of four PFOA-ions environments on PFOA were investigated. Results showed a remarkable 277% increase in PFOA attenuation rate (λ) in microbe−Fe x S y media (0.343 h −1 ) than in Fe x S y (0.091 h −1 ) alone. The ion inhibiting effect on PFOA attenuation was demonstrated (λ from 0.343 to 0.159 h −1 ), with the maximum effect in HCO 3 − . It can be attributed to the occupation of sites by HCO 3− which led to a greater repulsion. More PFOA was dispersed into distant regions (low reaction zone). Moreover, SO 4 2− or NO 3 − with microbe−Fe x S y interaction exhibited pronounced retardation effects (on PFOA). Notably, enhanced formations of2− and PFOA-NO 3 − environments. Pseudomonas reduced Fe 3+ to Fe 2+ , and Rhizobiales contributed to producing 3 Fe 2+ after consuming 2 Fe 2+ . Fe 2+ and Pseudomonas combined to drive PFOA multipath chain reaction. This provided a theoretical basis for understanding PFOA cross-media transport and fate in microbe−mineral−ions interaction environments.
