Abstract: Alappad coast in Kollam district, the south-west coast of Kerala, India is one of the severely devastated areas by 26 December 2004 Indian Ocean Tsunami. This study discusses the hydrochemical facies of tsunami affected dug wells along this coastal segment after the tsunami impact from the year 2005, 2008, 2012 and 2014. The groundwater chemistry with respect to sodium chloride ratio, sodium adsorption ratio and salinity hazard were evaluated. The hydrochemical facies of the water sources has been saline water type with Na+- K+ - Cl- - SO 2- in 2005 and 2008. Studies conducted in 2012 shows the water behavior changed to temporary hardness water type with dominants of Ca2+- Mg2+- HCO and continued to be same in 2014. Reverse ion exchange process in water sources analyzed in 2005 is the indication of salt water contamination and it gradually changed to ion exchange in 2012. On the basis of sodium adsorption ratio and salinity hazard water sources from 2012 are low sodium water with medium salinity which is suitable for irrigation.
