- People on globe are suffering from various problems due to undesired changes in physical, chemical and biological characteristics of air , water and soil. Apatite , fluoride and biotite are the several rocks having fluoride bearing minerals. The weathering of this rocks and infilteration of rainfall through it increases fluoride concentration in ground water. Human population suffers from various water bond disease due to contaminated drinking water therefore it is neccessary that the quality of drinking water should be checked at regular interval. Fluorides and fluorosis issues are common in fue nations including India . Flourides higher than 1.5mg/l causes dental and skeletal fluorosis . The ground water sample was collected from three villages Dongargaon , Sakharagaon and pandharkawda of Maharashtra containing fluoride concentration. The result show that Sakhara contains maximum fluoride concentration 5.21mg/l . The various studied techniques for defluoridation are coagulation, precipitation and adsorbtion process. For defluoridation, adsorbtion process is more favoured and economical. The various adsorbent including activated carbon, chalk powder, agricultural waste (orange peels, pineapple peels , banana peel ) is used to keep up standard limit of fluoride concentration in drinking water
