The problem of high fluoride in groundwater is one of the most important health related geo-environmental issue. It is beneficial up to certain limits but excess intake (i.e. >1.5mg/L) may cause fluorosis. Fluoride in groundwater was studied in Sanganer tehsil of Jaipur district. 18 villages were under surveillance. Groundwater samples were periodically collected and analyzed for physico-chemical parameters including Fluoride (F^-), pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), total hardness, Calcium (Ca²⁺), Chloride (Cl^-) and alkalinity. The analytical results revealed considerable variations in the chemical composition of water samples. Fluoride concentration varies from 0.20 to 6.45 mg/L.
