“…Therefore, monitoring of groundwater quality is essential in any basin or population area which affects the fittingness of water for household, industrial and agriculture use. Many researchers have worked on hydrochemical features, groundwater pollution, and its quality status for utilization in drinking and agriculture purposes in various basins and urban regions (Ahamed & Loganathan, 2017;Alaya, Saidi, Zemni, & Zargouni, 2014;Gowd, 2005;Patel et al, 2016;Raju, Ram, & Gossel, 2014;Raju et al, 2016;Singh, Tewary, & Sinha, 2011;Umar, Ahmed, Alam, & Khan, 2008). In the current study, an effort has been made to calculate the groundwater quality indices for the aptness of groundwater resource for drinking and agricultural purpose and identify the influences of natural and anthropogenic actions on groundwater chemistry.…”

“…Groundwater contamination is a worldwide problem that has economic and human health impact (World Health Organization [WHO], 1997). Groundwater quality of a particular area reflects input rain, water-rock interaction as well as human activities as agriculture, domestic and industrial waste of that area Raju et al, 2016). As the groundwater chemistry is very dynamic may possess different water quality in very close proximity and varies to seasonal and climatic factors (Ackah et al, 2011;Raju, 2007), analysis of groundwater excellence is significant to deduce aptness of subsurface water for household and agriculture uses.…”

This study is aimed to assess the groundwater excellence within the rural areas of Sant Ravidas Nagar (Bhadohi), Uttar Pradesh, India. In the current work, estimation of groundwater excellence indices has been done to recognize the water quality for the appropriateness of groundwater resource for drinking and agricultural use. Twenty groundwater samples were collected and investigated for diverse geochemical parameters viz, pH, total dissolved solids (TDS), total hardness, cations and anions. The groundwater of the study region is neutral to slightly alkaline in nature. Piper's diagram classification shows that majority of the samples belong to CaMgHCO 3 hydrochemical facies. Gibbs plot specifies that majority of samples falls in rock dominance. The water quality index shows that the entire sample is under excellent water category. On the basis of TDS, all the samples are within the range of desirable to permissible for drinking and agriculture purpose. Forty percent samples of the study region are having nitrate content more than permissible limit (>50 mg/l) which is not fine for individual use. Poor drainage, domestic waste and use of N fertilization on farming land may be the main sources of nitrate in groundwater of the study region. On the basis of different water quality indices, groundwater of the study region is fit for agricultural use.

“…The silicate minerals have changed along the flow path of the groundwater, indicating the degrees of water-rock interactions and residence time. All samples are on the right of the quartz line, suggesting that the quartz is saturated and in a relatively equilibrium state with the groundwater, and the SiO2 may be derived from amorphous silica [45]. The results showed that the degree of water-rock interaction and residence time increased gradually from the Gobi Belt to the basin center.…”

Groundwater is a critical water resource for human survival and economic development in arid and semi-arid areas. It is crucial to understand the groundwater circulation and hydrochemical evolution for sustainable management and utilization of groundwater resources in those areas. To this end, an investigation of the hydrochemical characteristics of surface water and groundwater was conducted in Nomhon, an arid area located in the Qaidam Basin, northwest China, by using hydrochemical (major and trace elements) and stable isotopes (δD and δ18O) approaches. Stable isotopes and ion ratios were analyzed to determine the recharge sources, hydrochemistry characteristics, and major hydrogeochemical processes. Meanwhile, inverse geochemistry modeling was applied to quantitatively determine the mass transfer of hydrogeochemical processes. The results showed that groundwater in the study area is mainly recharged by atmospheric precipitation in mountainous areas, and the groundwater in the center of basin might originate from ancient water in cold and humid environments. Along the groundwater flow path, the TDS of groundwater increased gradually from fresh to salty (ranging from 462.50 to 19,604.40 mg/L), and the hydrochemical type changed from Cl·HCO3–Na·Mg·Ca to Cl–Na. Groundwater chemical composition and mass balance modeling results indicated that from alluvial fan to lacustrine plain, the main hydrogeochemical processes changed from the dissolution of halite and albite and the precipitation of dolomite and kaolinite to the dissolution of halite and gypsum, precipitation of calcite, redox (SO42− reduction), and cation exchange. This study would be helpful for water resources management in this area and other similar areas.

“…Based on the principle of mass conservation, hydrogeochemical simulation can quantitatively calculate the amount of material transfer during water-rock interaction and the dissolution and precipitation state of various minerals, mapping the evolution of the groundwater [21][22][23]. The graphics of multimineral stability are used to analyze the main water-rock interaction in a groundwater system from the perspective of mineralogy and its application in hydrogeochemical research can provide more intuitive evidence [24][25][26]. The purpose of this study is to discuss the unique hydrochemical characteristics of the thermal groundwaters of Chongqing and the compositional evolution of the major ions in the geothermal reservoir, using field and historical data and combining the main hydrochemical methods with simulation models.…”

Thermal groundwater in the Lower and Middle Triassic carbonates in Chongqing, China, is mainly concentrated in anticlines. Hot springs (32.9 to 57 °C) with SO4-Ca type waters and Total Dissolved Solids (TDS) of 1620 to 2929 mg/L emerge in the middle and the plunging ends of the structures. Multivariate methods are used to analyze the hydrochemical characteristics of the waters, and identify the sources of the main dissolved components, providing an insight into the evolution of the environment in which they formed. Hierarchical cluster analysis of compositional data differentiates samples in the study area into three categories: high TDS-high Ca2+ and SO42− water; medium TDS-high Na+ and Cl− water; and low TDS-high HCO3− water. Factor analysis and ion ratio relationships show that Ca2+ and SO42− are mainly derived from the dissolution of gypsum and anhydrite within the geothermal reservoir, with some addition of SO42− from coal-bearing cap rocks. The main source of HCO3−, is in the dissolution of dolomite and CO2 that also promotes the incongruent dissolution of albite and K-feldspar, adding Na+ and K+ to the groundwater. Reverse modelling of the transfers of each phase shows, in three models, that the minerals dissolved decrease progressively—with the exception of halite and albite. Combined with the hydrochemical characteristics of hot water in the same reservoir in the adjacent area (Cl-Na type, TDS of 13.37 g/L), a process of desalination of the hot water can be confirmed, which has not yet reached the ‘freshwater’ stage dominated by HCO3−.
