Abstract
This study was carried out to assess the fluoride concentration in groundwater of Peddavagu basin, Adilabad District. Where groundwater is the main source of drinking water. Water samples collected from bore wells were analyzed for pH, Electrical Conductivity (EC), Nitrate (NO3-) and Fluoride (F-) content. Fluoride concentration of groundwater ranges from 0 to 4.54 mg/l. Out of 31 water samples studied 20 samples have fluoride concentration below 1 mg/l and 11 water samples have fluoride concentration above 1 mg/l. As per the desirable and maximum permissible limit for fluoride in drinking water (1.5 mg/l) prescribed by WHO (2004) and Bureau of Indian Standards (2009), 35.4% groundwater sources in the study area is unfit for drinking purposes. Due to the higher fluoride levels in drinking water several cases of dental and skeletal fluorosis have appeared at alarming rate in the investigated area. The wells in the investigated area have been demarcated into safe and unsafe wells for consumption of water with respect to fluoride concentration.
