Abstract: The Gadilam river basin in Tamilnadu is characterized by different geological formation viz. Archaean, Cretaceous, Tertiary to Recent Alluvium and groundwater serves as the major source for domestic, agriculture and other water-related activities. Forty four groundwater samples were collected during summer and post monsoon. Twenty three samples were analysed for stable isotopes (δ¹⁸O and δD). Geochemical signatures of groundwater were used to identify the chemical processes that control hydrogeochemsitry. Chemical parameters of groundwater such as pH, EC, TDS, Na⁺, K⁺, Ca⁺, Mg⁺, HCO₃⁻, SO₄⁻, PO₄⁻ and H₄SiO₄ were determined. Interpretation of hydrogeochemical data ascribes that secondary leaching, saline water intrusion and anthropogenic impact in this regime. Interpretation of δ¹⁸O and δD indicates recharge from the meteoric water in Tertiary aquifer and from evaporated water in Alluvium aquifer.
