The Quality of Groundwater in Jaipur Region with Emphasis to Fluoride Concentration.

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 physicochemical 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. [ABSTRACT FROM AUTHOR]
