“…(Na + + Cl − + K + ) indicates the increment of Na + in the system by the processes other than halite dissolution, while [(Ca 2+ + Mg 2+ ) – (SO 4 2− + HCO 3 − )] represents the increment of cations Ca 2+ and Mg 2+ that are credited to processes excluding carbonate or silicate weathering (dissolution of gypsum, calcite, and dolomite) [ 78 ]. A linear relation between the parameters with slope equal to −1 indicates the significance of ion exchange as an important factor controlling the groundwater chemistry and its evolution [ 79 ]. According to Figure 7 b, the relationship between parameters shows linearity with a slope value of −0.931 (Equation (16)), which is very close to the theoretical value of −1, indicating the ion exchange between Na + , Ca 2+ , and Mg 2+ .…”

Groundwater is the most important water resource, on which depends human geo-economic development and survival. Recent environmental changes and anthropogenic activities render groundwater severely vulnerable. Groundwater in Central Sindh, Pakistan, is facing a similar situation. Hydrogeochemical characteristics of the groundwater in the said region were investigated by analyzing 59 groundwater samples via agricultural and drinking indices, using various statistical methods and graphical approaches to identify factors affecting groundwater. Major reactions occurring in the groundwater system were quantified by hydrogeochemical modeling. A statistical summary reveals the abundance of cations is Na+ > Ca2+ > Mg2+ > K+, while the abundance of anions is HCO3− > Cl− > SO42. Groundwater chemistry is mainly of rock dominance. Correlation analysis and graphical relationships between ions reveal that ion exchange and rock weathering such as the dissolution of halite, albite, and dissolution of carbonate minerals are important rock–water interactions, governing the evolution of groundwater chemistry. Hydrochemical facies are predominantly of mixed CaMgCl and Na-Cl type, with few samples of Ca-HCO3 type, which constitutes fresh recharged water. Based on the Water Quality Index (WQI), 28.82% samples were found to be unsuitable for drinking. A United States Salinity Laboratory (USSL) diagram, Wilcox diagram, and other agricultural indices indicate that majority of the groundwater samples fall within the acceptable range for irrigation purposes.

“…The (Ca 2+ + Mg 2+ ) − (HCO 3 − + SO 4 2− ) equation means that the cations Ca and Mg were corrected by omitting the influences by other processes (e.g., carbonate or silicate weathering), whereas the (Na + + K + ) − Cl − equation means that the cations K and Na were from sources other than their respective chlorides [49]. If ion exchange is the dominant process in the system, the samples should form a line with a slope of −1 [16,20,42,49]. Figure 6e shows that cluster 1 and cluster 2 samples have a slope of −1, indicating cation exchange influences the groundwater chemistry of these samples, and cluster 3 has a slope of −0.6, indicating that cation exchange shows less influence on the water chemistry in cluster 3 than it does in the other clusters.…”

“…The geologic structure is complicated, with two faults cross-cutting the study area. Geological structures play a substantial role in many qualitative and quantitative studies of hydrogeological processes [15,16]. Rajabpour et al [16] investigated the influence of the North Tabriz Fault on the alluvial aquifer northwest of Tabriz, Iran, which showed quite different hydrochemical properties on either side of the fault.…”

Rajabpour et al [16] investigated the influence of the North Tabriz Fault on the alluvial aquifer northwest of Tabriz, Iran, which showed quite different hydrochemical properties on either side of the fault. Hagedorn and Whittier [17] used the geochemical data to identify solute sources and mixing processes between various water types in a region that experienced multiple lithospheric extension events, and found a remarkable heterogeneity in alluvial spring and groundwater chemistry.…”

Abstract:Knowledge of hydrochemical processes in groundwater helps to identify the relationship between geochemical processes and groundwater quality as well as to understand the hydrochemical evaluation of groundwater, which is important for the sustainable management of groundwater resources. This study aims to identify the chemical characteristics of groundwater in the area of Tongchuan City, China. A total of 58 groundwater samples were collected. A hierarchical cluster analysis divided samples into three clusters and six sub-clusters (cluster 1a, 1b, 2a, 2b, 3a, 3b) according to hydrochemical facies. Graphical plots of multiple ionic ratios, saturation indices, and ion exchange indices were employed to examine hydrochemical processes that result in different hydrochemical facies of each cluster. Results show the predominance of carbonate and silicate weathering in cluster 1, silicate weathering in cluster 2, and carbonate weathering in cluster 3. Ionic exchange is a ubiquitous process among all clusters. The distribution of clusters is related to the regional geology, which may result in different hydrochemical processes. Two stratigraphic sections identify the differences in hydrochemical processes resulting from complex stratum structures and varied aquifer media. Cluster 2a shows an interesting difference in water chemistry along the groundwater flow path. Further study by oxygen and hydrogen isotope indicated that mixing between Quaternary and the Permian aquifers resulting from faulting is the main reason for the distinctive characteristic of cluster 2a.
