Hydrogeochemistry of the groundwater is controlled by rock-water interaction was characterized using Gibbs plot. The groundwater in the study area is dominated by HCO₃⁻ and Na+ facies character with alkaline nature. The correlation technique has been used to understand the relationship between chemical parameters. The adversative health effect by in taking fluoride contaminated groundwater by humans including male, female and children are the major concern in this study by using secondary data. Among all the samples, seven samples were recorded above the permissible limit of fluoride during the post-monsoon season.
