Major ion correlation in groundwater of Kancheepuram Region, South India.
Groundwater samples were collected from both dugwells and borewells in an intensively irrigated area of Kancheepuram Taluk, Tamil Nadu. pH, EC and TDS of groundwater samples were measured in the site. The collected samples were analysed in the laboratory for Ca, Mg, Na, K, Cl, HCO3, CO3, SO4, NO3, P-PO4 and Si-SiO2. The results are used for inter elemental correlation analysis which indicates that most of the elements having good correlation. Piper Trilinear diagram is used to find out the hydrochemical type of groundwater which shows that most of them are CaHCO3 and the remaining are CaMgCl type. Hydrochemical characteristics of groundwater indicate that silicate weathering reaction is a probable source for high concentration of major ions.
