“…Groundwater chemistry is dependent on several factors including the nature of recharge, the residence time of groundwater in the aquifer, rock-water interaction beneath the surface, chemical weathering rates and anthropogenic activities (Andre et al, 2005;Ekwere and Edet, 2012;Loh et al, 2016;Rao et al, 2019 andSivakarun N, et al, 2020). Each groundwater system in an area has a distinctive suite of chemical components, which is attributed as a result of chemical changes in the rainwater as it percolates through the aquifer system (Back,1966;Derver,1988;Zhu et al, 2004).…”

Mountainous catchments are one of the world's important water sources that sustains a major portion of global population and a rich biodiversity. The groundwater quantity and quality of mountainous watersheds are depended generally on the geologic characteristics and climate gradients. Although many groundwater studies have been carried out in the midlands and lowlands of many river basins, not enough focus has been paid to the mountainous catchments of tropics. Here we report a case study on groundwater quality and controlling factors of a mountainous catchments of the Western Ghats mountain ranges of peninsular India -the Bhavani river basin, which is identi ed as a testbed for longterm monitoring of the Critical Zone process. A total of 88 water samples were collected seasonally for assessing various physico-chemical parameters, solute contents and scaling properties. The results of the study revealed that the hydrochemistry of groundwater is in uenced by both silicate and carbonate weathering. Mineral stability indices computed for the groundwater reveal that about 52 % of the samples are supersaturated with carbonate minerals and often exhibit scaling due to solute overloading. Among the contributing factors that determine water quality of groundwaters, chemical weathering and anthropogenic activities play a signi cant role.

This work aims to investigate the hydrochemical characteristics and formation mechanisms of shallow groundwater in a part of the Nanchang section of Ganfu plain. The hydrochemical data from 90 groundwater samples were interpreted by the methods of mathematical statistics, Piper diagrams, Gibbs plots, ratio graphs of ions, and geochemical modeling. The results show that shallow groundwater is weakly acidic, the average concentration of cation in groundwater decrease in Ca2+ > Na+ > Mg2+ > K+, and the abundance is in the order HCO3− > NO3− > SO42− > Cl− for anions. The hydrochemical type of groundwater was dominated by HCO3-Na·Ca·Mg, HCO3·Cl-Na·Ca·Mg, and HCO3-Na·Ca. Moreover, the main controlling factor of groundwater hydrochemistry is water-rock interactions. Na+ and K+ mainly originate from the dissolution of halite. Ca2+ and Mg2+ are mainly controlled by carbonate dissolution, while the main anions come from the dissolution of evaporite and carbonate. The groundwater chemical evolution is affected by the dissolution and precipitation of the mineral phase and cation exchange.

“…The nature of groundwater is determined by the extent to which it has reacted with country rock (Edmunds and Gaye, 1994). The quality of groundwater is a function of multiple parameters and processes such as evaporation, selective uptake by vegetation, oxidation/reduction, wet and dry depositions of atmospheric salts, soil/rock-water interactions, cation exchange, dissociation of minerals, precipitation of secondary minerals, mixing of waters, pollution of lake/sea, leaching of fertilizers and manure, and other biological process (Eraifej and Sivakarun et al, 2020). Regular monitoring of quality parameters allows for the maintenance of a healthy ecosystem balance while also ensuring the long-term management of water resources.Quantity of dissolved constituents is higher in groundwater than that of surface water as it is exposed to soluble Groundwater quality evaluation for drinking and irrigation purposes in and around Bemetera Block, Chhattisgarh, India The hydrochemical evaluation and geospatial distribution of various chemical parameters in the block Bemetara, Saja and Berla has been attempted in this study.…”

The quality of groundwater inan area is just as essential as the quantity. The groundwater quality of the Bemetera Block of Chhattisgarh State, in terms of domestic and irrigation use was studied. The hydrogeochemical evaluation, demonstrates that except of TH, SO42-, Ca2+, Mg2+, and Fe, all measured physical parameters in the study area fell within the Bureau of Indian Standards (BIS) limit. Further, certain sampling locations, such as S5 (Deep Aquifer), S9, S13, and S20, have a negative influence on drinking water quality as compared to others (shallow aquifer). Along with water quality analysis for the driking purpose, the irrigation water quality of the area was examined using several methods, and observed that most of the samples are suitable for domestic and irrigation purposes and some are not suitable.
