Abstract

The partial pressure of Carbon-Di-oxide plays a significant role in the water chemistry. It reflects the geochemical process and relates to the saturation index (SI) of the Carbonate minerals. A total number of 98 samples were collected from layered sequential aquifers like Alluvium, Upper Cuddalore sandstone, Lower Cuddalore Sandstone and Cretaceous formations, during Pre-Monsoon and Post-Monsoon seasons. Chemical parameters of groundwater such as pH, EC, TDS, Na⁺, K⁺, Ca²⁺, Mg²⁺, Cl^-, HCO3-, SO42-,PO43- and H₄SiO₄ were determined. The study shows that an increase in the log pCO₂ values during water-rock interaction which influences the process of mineral dissolution. Saturation index of the carbonate minerals like Calcite, Aragonite, Dolomite and Magnesite were derived and compared with the log pCO₂ values. In both the seasons the decreasing log pCO₂ increases the saturation index of most of the carbonate minerals studied. The saturation index of almost all carbonate minerals during both the seasons showed negative correlation irrespective of the formation. Log pCO₂ also develops a negative correlation with pH in groundwater of the study area.
