The hydrogeochemical regulating variables for the high rate of groundwater defilement in a semi-arid region's shallow hard rock aquifer have been collected. In the 2023 year, a total of thirty-six groundwater samples were tested throughout the pre- and post-monsoon seasons. High fluoride readings were found in areas of north-western, northern, southern, and north-eastern parts. Fluoride concentrations have been found in the research area, with between 53 and 39 percent of the water samples exceeding the acceptable 1 mg/l level in drinking water. The piper trilinear revealed that the primary groundwater types were Na-Ca-Cl and mixed Na-Ca-Mg-Cl-SO4. The majority of the area is rock dominant filed, according to Gibb's plot. The study region's water chemistry is dominated by weathering of feldspar minerals and cation exchange reactions. Groundwater chemistry is influenced by weathering of silicate group minerals and cation exchange processes. In addition, the Hazard Quotient (HQ) for fluoride in adults and children were determined.
