“…Geochemical processes, occurring within the groundwater and their reactions with the aquifer materials, are responsible for changes in groundwater chemistry (Drever 1988;Hem 1991;Wen et al 2008;Subba Rao and Surya Rao 2009). Geochemical studies of groundwater provide a better understanding of possible changes in quality as development progress (Sreedevi 2004;Jalali 2006;Nagaraju et al 2006;Subba Rao 2006;Gupta et al 2008Gupta et al , 2009Bhardwaj et al 2010). Urbanization and related anthropogenic activities also affect the groundwater quality (Whittemore et al 1989;Mondal et al 2005).…”

“…Subbarao et al (1996) used factor analysis to characterize the groundwater contamination by industrial effluents in a single hydrogeological unit. Gupta et al (2009) carried out geochemical assessment of groundwater with reference to water-rock interaction and suitability of groundwater quality in respect of drinking and irrigation purposes around Macherla-Karempudi area of south India. Hydrochemical studies conducted on groundwater quality of Solapur city revealed that dug wells are more polluted than bore wells and the groundwater contamination is mainly due to anthropogenic activities (Naik et al 2008).…”

Nagpur City located in semiarid area of central India is a fast-growing industrial centre. In recent years, rapid development has created an increased demand for drinking water, which is increasingly being fulfilled by groundwater abstraction. The present study was undertaken to assess major ion chemistry of shallow groundwater to understand geochemical evolution of groundwater and water quality for promoting sustainable development and effective management of groundwater resources. A total of 47 water samples were collected from shallow aquifer of selected parts of the city and the water chemistry of various ions viz. Ca(2 +), Mg(2 +), Na(+), K(+), CO(3)(2-), HCO(3)(-), Cl(-), SO(4)(2-) and NO(3)(-) are carried out. The chemical relationships in Piper diagram identify Ca-HCO(3)-Cl and mixed Ca-Na-HCO(3)-Cl as most prevalent water types. Alkaline earth exceeds alkalis and weak acids exceed strong acids. Ionic ratios and Gibb's diagram suggest that silicate rock weathering and anthropogenic activities are the main processes that determine the ionic composition in the study area. The nitrate appeared as a major problem of safe drinking water in this region. We recorded highest nitrate concentration, i.e., 411 mg/l in one of the dug well. A comparison of groundwater quality in relation to drinking water quality standards revealed that about half of the shallow aquifer samples are not suitable for drinking.

“…2) and Table 2 show that although in the majority of river water samples Ca 2+ + Mg 2+ exceed Na + + K + , in most of the groundwater samples, the contribution of alkalis (Na + + K + ) exceeds alkaline earths (Ca 2+ + Mg 2+ ). In these samples, sodium drives from natural ion exchange where Na-montmorilonite clay reacts with calcium and magnesium and releases sodium into the water (Gupta et al 2009). …”

In order to assess the quality and suitability of waters in the Kor-Sivand river basin, 60 water samples from the Kor river and 90 water samples from wells in the basin were studied. Assessments were based on Piper's and Gibbs' diagrams for water quality, Food and Agricultural Organization's (FAO) guidelines, and US Salinity Laboratory diagram for water suitability. The results showed that the river water is of Ca-HCO(3) type, while well water is of Ca-Cl and Na-Cl type. Based on Gibbs' diagram, the source of soluble ions in the river water samples is the weathering of stones over which water flows, while evaporation was found to be the dominant process in the ion concentration of the well samples. According to the FAO Guidelines, the salinity of surface water for irrigation did not cause great restrictions; however, many of these waters could create potential permeability problems. In the groundwater samples, a high salt concentration is more important than the infiltration problem. Mg hazard values at some sites limit its use for agricultural purposes. One third of the river water samples and two thirds of well waters had more than 50% magnesium. Saturation indices showed that 94% of the analyzed water samples are supersaturated with calcite, aragonite, and dolomite. Based on the US Salinity Laboratory diagram, river water samples were classified as C(2)S(1) and C(3)S(1), while C(4)S(3), C(4)S(4), C(2)S(1), and C(3)S(1) were the most dominant classes in well samples. Some management practices necessary for sustainable development of water resources in the study area were discussed briefly, including appropriate selection of crops, adequate drainage, leaching, blending and cyclic use of saline water, proper irrigation method, and addition of soil amendment.

Groundwater is the prime source in the area of Varaha River Basin, Andhra Pradesh, India. Groundwater samples collected during pre-and post-monsoon were analyzed for major ion chemistry to understand the operating mechanism of geochemical processes for variation of groundwater quality. Low ionic concentration is observed in the groundwater occurring at topographichighs and towards the river compared to the rest of the area. This is caused by the influence of recharge water. Geochemistry of groundwater is observed to be mainly controlled by the rock-weathering, mineral dissolution, leaching, ion exchange and evaporation, and is subsequently modified by the anthropogenic and marine activities. Contribution of residual soluble salts below the depth of 5 m from the ground surface is high, while it is low beyond the depth of 5 m. Anthropogenic activities cause an accumulation of excess residual soluble salts in the former depth and the content of this soluble matter is reduced by the clay products beyond the latter depth. Seasonal ionic concentration of groundwater is greatly influenced by the recharge process with reference to topographical features, lithological characteristics and anthropogenic activities. Groundwater quality is classified as mixed and non-carbonate alkali groups due to a combined action of geogenic/anthropogenic and marine sources, respectively. The groundwater quality is above the adequacy level for both drinking and irrigation, and appropriate management measures are recommended for sustainable development.
