Abstract—Some studies on discrepancy of silica concentrations in groundwater of hard rock aquifers of lower permeability stipulates the increase in residence time, which mainly leads to increase in assemblage of ions. In order to understand the hydrogeochemistry of the groundwater of a hard rock aquifer and its relation with silicates, 120 groundwater samples were collected and analyzed to demonstrate spatial coverage and represent different litho units in Villupuram district. This analysis has been carried out mainly for of major cations (Ca2+, Mg2+, Na+, K+) and anions (Cl, HCO3-, SO42-, PO4-, NO3-, H4SiO4) present in the water samples. Physico-chemical parameters like pH, TDS (Total Dissolved Solids), Temperature and EC (Electric Conductivity) were also analyzed to determine the water quality. The results of silica showed different ranges of concentrations and were plotted in different formations. To understand the reason behind this dissimilarities, different techniques like Thermodynamics, Statistics and GIS were adopted.
