Groundwater quality is one of the important criteria to judge the economic status of the country. Groundwater is an important source of water for drinking and irrigation uses in Tamil Nadu, India. The present study aimed to evaluate the quality nature of groundwater for drinking and irrigation uses associated with water quality index (WQI), nitrate pollution index (NPI), fluoride pollution index (FPI), human health risk assessment (HHRA), and irrigation indexes using GIS platform. A total of 36 samples were collected and analyzed for pH, electrical conductivity, total dissolved solids, total hardness and major ions such as calcium, magnesium, sodium potassium, chloride, sulfate, fluoride, nitrate, carbonate, and bicarbonate. The result of the WQI reveals that 25% of the samples fall good, 36.11% of the samples fall moderate, 27.77% of the samples fall doubtful, and 11.11% of the samples fall unsuitable for drinking purpose. Based on the NPI, 11% of the samples were polluted due to elevated concentration of nitrate in groundwater. FPI reveals that 63.88% of the sample locations were highly contaminated zones in the study area. The results of the noncarcinogenic risk assessment reveal that children were highly exposed to health risk due to continuous intake of fluoride contaminated drinking water compared to adult (male and female). Interpolation of irrigation water quality index shows that EC, sodium, magnesium, and bicarbonate highly influence the nature of groundwater for agricultural activities.
