ABSTRACT
Groundwater acts as a lifeline in the coastal regions to meet out the domestic, drinking, irrigational and industrial needs. In this scenario 29 shallow coastal groundwater samples were collected and analysed for major and minor cations. The samples analysed were classified w ith SAR, RSC, TH, CI, IBE, EC and facies to determine their utility. The geochemical facies of the groundwater was attempted and found that Ca-HCO3 as the dominant type. The factors responsible for their geochemical characterization were also attempted by using standard plot and it w as found that the ion exchange plays a significant role along with few signatures of recharge and sea water intrusion.
