An investigation was conducted using the secondary data to identify the domestic groundwater quality through Water Quality Index (WQI) method. Piper diagram for to understand groundwater chemistry indicates mixed type of water, with the relative order of Cl−>HCO3>SO42-for anions and Na+/K+>Mg2+>Ca2+ for cations. Pearson Correlation Coefficient technique were adopted to find out the relationship between the water quality parameters were identified positive correlation between HCO3− - F− during pre-monsoon and with Na+ - pH and K+ - pH during the post-monsoon season at a significant level of 0.01. The WQI results revealed that 52 percent of samples during pre-monsoon and 40 percent in post-monsoon are under the excellent category during the study period. About 9 and 16 percent of samples fall under poor quality during the study period. The quality of groundwater for domestic purposes in the study area is slowly changing its original quality.
