Use of Hydrochemistry and Stable Isotopes as Tools for Groundwater Evolution and Contamination Investigation in Thirumanimuttar Sub-Basin, Tamilnadu, India
Hydrochemical and isotopic studies in groundwater was attempted in a basin to gain knowledge on geochemical evolution and water quality status. The results of the chemical analysis indicate the sources of ions into the groundwater are from dissolution and leaching from source rocks, cation exchange and anthropogenic activities. The saturation index calculated indicate oversaturation of carbonate species and undersaturation of amorphous silica indicating groundwater chemical evolution is controlled by water rock interactions. Water type alters from Ca-HCO3 to Na-Cl indicating their hydrochemical evolution and flow path. The water types classification indicates 5 distinct groups ranging from low EC and highly depleted isotopes to very high EC with enriched stable isotopic composition indicating longer residence time of groundwater.
