Abstract—The region like Vellore has a higher density of population to be supported with water. Nearly greater than 50% of the day to day need of people in this Arakonam Taluk including domestic, industrial, agricultural and partly drinking purpose is made by the groundwater resources only. A study on hydrogeochemistry is done to understand the utilization of groundwater for various purposes. A total of 12 groundwater samples were from various parts of Kaveripakkam Block were collected and Physico-chemical parameters [pH, Electrical Conductivity (EC) and Total Dissolved Solid (TDS)], ions (Na, K, Cl, HCO3,Ca, Mg, SO4, PO4, H4SiO4) were analyzed to understand the suitability of groundwater for consumption, cultivation and household purpose and also to identify the hydrogeochemical processes.The Piper trilinear diagram and USSL diagram were also plotted which indicates CaHCO3 facies and shows high salinity hazard. Quality of groundwater has been measured to ensure its suitability for consumption and irrigation, based on WHO standards, US Salinity Laboratory (USSL), Sodium Absorption Ratio (SAR), Residual Sodium Carbonate (RSC), and Na%. The study implies that most of the groundwater samples are suitable for irrigation and drinking purposes. The study also identified that hydrogeochemistry of the region is mainly influenced by weathering processes.
