“…The lithology of the study area has two stratigraphic units as follows: (1) Tertiary unit, argillaceous sandstone, pebble bearing grits, clays (variegated) with lignite seams and pebble beds, (2) Quarternary unit, soils, alluvium and coastal sands and laterite. Prasanna et al (2008) conducted electrical sounding in some of the locations in the study area. The maximum depth of investigation is 60 m. The nature and distribution of different lithologic layers as represented by depth-wise resistivity values are correlated with geoelectrical logging data to show the existing hydrogeological environment in the region (Fig.…”

Hydrogeochemical investigations are carried out in and around Perumal Lake, Cuddalore district, South India in order to assess its suitability in relation to domestic and agricultural uses. The water samples (surface water = 16; groundwater = 12) were analyzed for various physicochemical attributes like pH, electrical conductivity (EC), sodium (Na ? ), potassium (K ? ), calcium (Ca 2? ), magnesium (Mg 2? ), chloride (Cl -), bicarbonate (HCO 3 -), sulfate (SO 4 2-), phosphate (PO 4 ), silica (H 4 SiO 4 ) and total dissolved solids (TDS). Major hydrochemical facies were identified using Piper trilinear diagram. Hydrogeochemical processes controlling the water chemistry are water-rock interaction rather than evaporation and precipitation. Interpretation of isotopic signatures reveals that groundwater samples recharged by meteoric water with few water-rock interactions. A comparison of water quality in relation to drinking water quality standard proves that the surface water samples are suitable for drinking purpose, whereas groundwater in some areas exceeds the permissible limit. Various determinants such as sodium absorption ratio (SAR), percent sodium (Na%), residual sodium carbonate (RSC) and permeability index (PI) revealed that most of the samples are suitable for irrigation.

“…6b, d). The higher concentration of 222 Rn is noted in same pH as that of U in groundwater and in rest of the samples it is observed no significant relationship between pH and 222 Rn in groundwater [32]. The relationship between U, 222 Rn and EC is plotted in the Fig.…”

A study was conducted to understand the occurrence of the radionuclides in groundwater of crystalline hard rock region. Samples were collected to analyze major cations, anions, U, 222 Rn and stable isotopes of oxygen, hydrogen. It was inferred that few samples have U and 222 Rn concentrations higher than the permissible limit of drinking water standard. High degree of weathering of granitic rocks and long contact time of groundwater with the aquifer matrix could be the reason for enhanced U and 222 Rn levels in groundwater. The association of U with SO 4 also proves that there exists anthropogenic influence in groundwater composition.

“…The electrical conductivity (EC) can be influenced by the presence of fine sediment (Fenn 1987), interaction of rock with water (Srinivasamoorthy 2007), anthropogenic (Prasanna et al 2008), sea water intrusion into the aquifers (Chidambaram et al 2005), etc. Moore et al (2008) discusses the factors that govern the spatial and temporal variability of electrical conductivity and illustrate how these variations can be used as indicators of water chemistry and hydrologic process.…”

“…Comparative chemical compositions of aqueous extracts from representative clays showed that the concentration of a 'dissolved element' in an extract depends not only on the amount present in the sample but also on its aqueous solubility, the pH and Eh of the system, its possible combination with other ions present, the effect of organic matter as a component and complexes, the ion-exchange effect and dispersibility of colloidal clay particles (Keller et al 1989). The groundwater plays a significant role in the disintegration and decomposition of rock masses and minerals to soil and then to clay particles; during the process the aqueous system attains equilibrium with the composition of these clay minerals which decides the fate of dissolution of minerals and the chemical evolutionary pathways (Venturelli et al 2003;Gomez et al 2006;Chidambaram et al 2007a;Prasanna et al 2008). In reality, a number of kinetic reasons exist that may cause systems to behave differently than predicted (Nordstrom and Ball 1989;Busby et al 1991).…”

Significance of saturation index of certain clay minerals in shallow coastal groundwater, in and around Kalpakkam, Tamil Nadu, India

et al. 2011

The saturation index of clay minerals like Gibbsite, Kaolinite, Illite, Montmorillonite and Chlorite in groundwater were studied in detail by collecting 29 groundwater samples from the shallow coastal aquifers in and around Kalpakkam. The samples collected were analysed for major cations, anions and trace elements by using standard procedures. The study reveals that pH has a significant role in the saturation index (SI) of minerals. It also shows that the relationship of electrical conductivity to the SI of these minerals is not significant than that of the ionic strength, log pCO 2 values, and alumina silica ratio have significant relation to the SI of these clay minerals. The SI of these clay minerals was spatially distributed to identify the areas of higher SI. Silica has good correlation to SI of Kaolinite, Gibbsite and Montmorillonite and Al has good correlation to SI of all the minerals except to that of Chlorite.
