“…S1 (supplementary material). The molar ratio of Na + /Clapproaching to 1 suggested halite dissolution as a sole source for Na in the groundwater [55]. However, in the present study, majority of the samples deviated from the equilibrium line; therefore, the increase of Na in groundwater may be caused by other sources, such as silicate weathering and albite contribution under anthropogenic stress; extensive human activities in the area are other contributing factors elevated Na levels in the aquifer.…”

Hydrochemical characteristics and aquifer properties present a better understanding of the mitigation of groundwater pollution, which has become one of the leading environmental concerns and threats to the sustainable ecosystem. Seventy-seven groundwater samples were collected from Sargodha District (Pakistan) and characterized for their physical and chemical properties. The analytical data were processed for the evaluation of the processes that control the groundwater chemistry using various drinking and agricultural indices with statistical and hydrochemical modeling. The predominant hydrochemical type was found to be Ca-HCO3 type, followed by Na-HCO3 and Mg-Ca-Cl types. The present study showed that the main factors controlling the groundwater chemistry were the prevalent rock dominance alongside the weathering of silicates, solubilization of carbonates, and cation exchange processes. Entropy water quality index (EWQI) revealed that 6.51% represented “poor water,” while 7.79% were considered “extremely poor” for drinking purposes. However, USSL classification, Wilcox diagram, and other agricultural indices (RCS, SAR, %Na, MH, PI, and PS) showed that the majority of the samples were classified as suitable for irrigation purpose. However, 16% of the samples for %Na and 24% of the samples for MH were not suitable for agricultural purposes. Overall, the groundwater quality was affected by the anthropogenic stress in the study area.

“…The two sub diagrams ( Figure 8 a,b) include relationship of TDS with weight ratio of (Na + + K + ) versus (Na + + K + + Ca 2+ ) and TDS with weight ratio of Cl − versus (Cl − + HCO 3 − ). According to Gibbs’ diagram, three factors influence the groundwater chemistry, which include rock dominance, evaporation dominance and precipitation dominance [ 80 , 81 ]. According to Figure 8 , most of the samples lie in the rock dominance zone, indicating that rock weathering is the primary source that controls the groundwater chemistry and its evolution.…”

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.

Groundwater is a vital resource for human life and economic growth. In the Khanewal district of Punjab, Pakistan, environmental changes, and anthropogenic activities have made groundwater extremely vulnerable in the past forty years. Sixty-eight groundwater samples were collected from the study area, major ions and trace elements were analyzed. The Principal Component Analysis and Cluster Analysis were used to identify the major factors influencing groundwater quality, as well as to assess its suitability for drinking and irrigation in southern Punjab. The aquifers are slightly acidic to alkaline, according to the pH (6.9–9.2) of groundwater. Significant cations are distributed as follows: Na+ > Ca2+ > Mg2+ > K+, while anions are distributed as HCO3− > SO42− > Cl−. The main hydrochemical facies are mixed Na·Ca-HCO3 and Na·Ca (Mg)-HCO3·SO4. Rock weathering processes, such as the dissolution of calcite, dolomite, and gypsum minerals, governed groundwater hydrochemistry. The water quality index (WQI) indicates that 17.64% of the water samples are unsuitable to drink. However, according to the Wilcox diagram, the USSL diagram, and some other agricultural indices, approximately 68% of the groundwater samples are suitable for irrigation.
