A study on the utility and geochemistry of groundwater in Ponneri taluk of Thiruvallur District, Tamilnadu

Abstract

Groundwater, throughout the world it had become important for human survival. Its physical, chemical and bacteriological properties determine the suitability for human consumption. 27 groundwater samples have been collected in south west monsoon season representing the Ponneri Taluk, Thiruvallur district of Tamilnadu. The physicochemical parameters include pH, TDS, cations such as Ca, Mg, Na and K, anions such as Cl, SO4, HCO3 and NO3, PO4. The samples were classified with sodium absorption ratio, salinity hazard, residual sodium carbonate, sodium percentage (Na%) and permeability index for irrigation, Total hardness and corrosivity index. The classification for drinking water is obtained by drinking water quality index (DWQI). The geochemistry has been studied using piper plot.
