This investigation was done to survey the fluoride focus in groundwater of Narayankher region, Medak District, where groundwater is the principle wellspring of drinking water. Water tests gathered from bore wells were investigated for pH, Electrical Conductivity (EC), Nitrate (NO3 - ) and Fluoride (F-) content. Fluoride grouping of groundwater ranges from 0.4to 2.3 mg/l. Out of44 towns contemplated 41 towns have fluoride fixation beneath 1 mg/l and 3 towns have fluoride focus over 1mg/l. 7 % towns have fluoride over 2 mg/l and 1% towns have fluoride over 2.2 mg/l. According to the alluring and most extreme allowable point of confinement for fluoride in drinking water (1.5 mg/l) endorsed by WHO (2004) and Bureau of Indian Standards (2009), in tree towns groundwater sources in the examination zone is unfit for drinking purposes. Because of the higher fluoride levels in drinking water a few instances of dental and skeletal fluorosis have showed up at disturbing rate in the explored zone. The wells in the examined territory have been delineated into protected and risky wells for utilization of water concerning fluoride and nitrate
