“…The QA and BA samples were collected from depth ranges of 5-35 m and 10-40 m, respectively. Samples were collected and analyzed according to standard methods and approaches used in previous studies [1,19]. The polyethylene bottles were cleaned using groundwater after a pumping time of about 30 min [1,6].…”

“…Samples were collected and analyzed according to standard methods and approaches used in previous studies [1,19]. The polyethylene bottles were cleaned using groundwater after a pumping time of about 30 min [1,6]. The pH and total dissolved solids (TDS) of groundwater were first tested immediately after groundwater sampling, and then, the samples were stored at 4 • C immediately after sampling for further analyses.…”

“…The mechanisms of the natural circulation process, as well as unnatural factors, govern the hydrochemical characteristic of groundwater during its movement processes. The formation and hydrogeochemical processes of groundwater are affected by various complex factors, including the recharge source, groundwater flow direction, evaporation, rock weathering, soil property, ion exchange, saline water mixing and anthropogenic activities [1,6].…”

“…Kim et al (2017) [12] revealed that the statistical and graphical methods are useful tools for assessing groundwater quality and hydrogeochemical processes. Aminiyan et al (2020) [1] used the principal component analysis and Pearson's correlation to determine the relationship between hydrochemical parameters, whereas Perera et al (2022) [13] used GIS techniques for mapping the spatial variation of physicochemical parameters of groundwater and groundwater quality index.…”

Groundwater resource is vital for industrial, drinking and irrigation purposes in the Dagujia river basin, China. The objective of this work was to comprehensively assess the hydrochemical characteristics and evolution processes of the Quaternary aquifer (QA) and the bedrock aquifer (BA) of the basin using statistical methods and hydrochemical plots. In total, 56 groundwater samples were collected from the QA (34 samples) and BA (22 samples). In addition, statistical methods combined with the geographic information system were used to identify the hydrochemical parameters of groundwater, as well as its spatial distribution in the Dagujia river basin. The Piper diagram showed that Ca-Na-HCO3 was the dominant groundwater facies type, while nine QA samples collected near the coastal line showed the Na-Cl facies type. On the other hand, the Gibbs diagram showed that most samples fell in the rock dominance zone. The principal component analysis results showed that the water–rock interaction and anthropogenic activities are the controlling factors, which is consistent with the results obtained using other methods. The results of this study indicated that rock weathering controls the hydrochemical characteristics of groundwater, while anthropogenic contamination and sea water intrusion are becoming increasingly serious issues for both QA and BA in the Dagujia river basin. Therefore, both Quaternary and bedrock aquifers require more attention.
