This study was carried out to assess the fluoride concentration in groundwater of Chandur Mandal, Nalgonda District, where groundwater is the main source of drinking water. Water samples collected from bore wells and open wells were analyzed for pH, Electrical Conductivity (EC) and Fluoride (F-) content. Fluoride concentration of groundwater ranges from 1.00 to 4.00 mg/l. Out of 15 samples from five villages studied 4 villages have fluoride concentration below 1 mg/l and 6 villages have fluoride concentration above 1mg/l. 5 villages have fluoride above 3 mg/l. As per the desirable and maximum permissible limit for fluoride in drinking water (1.5mg/l) prescribed by WHO (2004) and Bureau of Indian Standards (2009), 30% 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 the fluoride.
