HIGH FLUORIDE CONTENT IN DRINKING WATER IN VILLAGES OF DEOLI TEHSIL AND ITS IMPACT ON PUBLIC HEALTHK.S. MEENA AND R.K. GUNSARIAAbstract Fluoride (F-) Concentration over and above the permissible limits (1.5 mg/L) in drinking water leads to human health hazards, such as dental and skeletal fluorosis. Fifty ground water samples were collected from different villages of Deoli Tehsil, Tonk District, Rajasthan during the month of May-June 2009. Samples were analysed for different parameters such as- pH, total alkalinity (TA), fluoride (F-), nitrate (NO3 -) ,total dissolved solids (TDS), chloride(Cl-), total hardness(TH), electrical conductivity (EC), Ca-H, Mg-H, CO3 -2, HCO3 - Na+, K+ by using standard techniques. Ninety percent samples were found to have fluorides higher there permissible standards
