Hydrogeochemistry of groundwater in Chandanpur area of Odisha, India

A preliminary groundwater assessment was done in Chandanpur, located in the coastal district of Puri, Odisha, India. A hydrogeochemical investigation was attempted to find the dominant processes in influencing the groundwater quality. Stoichiometric ratios among the dissolved ions were calculated and correlation and trend line diagrams depicting the linear relationships among the various water constituents were ascertained. Linear relationships between TDS and Cl⁻as well between TDS and Na⁺ were seen. Hydrochemical facies of the groundwater using Piper Hill diagrams were investigated to determine the water type. Assessment of groundwater suitability for irrigation and drinking purposes based on parameters like sodium adsorption ration(SAR),residual sodium carbonate (RSC), permeability index (PI) were also determined. This preliminary study indicates that the groundwater in Chandanpur is fairly suitable for irrigation and drinking purposes.
