The aim of the present study is to assess the hydrogeochemical characteristics of groundwater in Palacode and Pennagaram taluk of Dharmapuri district, Tamil Nadu, India. In order to assess the groundwater quality, 158 groundwater samples were collected from bore well during monsoon and postmonsoon season in the year of 2013 and 2014. The groundwater samples were analyzed for different hydrogeochemical parameters such as pH, EC TDS,TH, Ca, Mg, Na, K, Cl, HCO3, F, SO4, PO4, and H4SIO4 using standard procedure. The analytical result reveals that the physical parameters of TH (Total Hardness) EC (Electrical Conductivity), TDS and chemical parameters Na, K, Cl, F, showed the above permissible limit of WHO standards. Whereas pH, Ca, Mg, SO4, H4SiO4 showed the below permissible limit. Based on the water quality index 8.9% of groundwater samples representing monsoon season exhibits “excellent water” 77.2% as good water, 13.9% as poor water whereas during post monsoon season 10.1% of samples represent “excellent quality” 72.2% of good quality water, 15% of poor water, 1.3% as very poor water quality and 1.3% as unsuitable for drinking purpose. On the basis of Sodium Adsorption Ratio (SAR) results with the values ranging from 0.6 to 3.9meq/l representing 77.3% of the monsoon season samples are suitable for irrigation purpose and in the post monsoon 85% of samples it ranges from 0.4 to 5.3 meq/l representing suitability for irrigation purpose.
