In this proceedings under way was concentrated on water collection samples in Tirunelveli district from well (open and bore well), tape, river and the pond. The results were characterised by physico-chemical and microbiological studies. Depending on the amount fluoride has both beneficial and adverse effects on human health. The allowable limit for fluoride in drinking water is 1.5 mg / L according to India's and the World Health Organization 's National Standards for Drinking Water Quality. Beyond this cap, fluoride can lead to a number of diseases including skeletal and dental fluorosis, brittle bones, cancer, infertility, brain damage, Alzheimer's syndrome and thyroid disease. Fluoride removal from the sample of drinking water is important for utility purposes. Among the literature methods, the adsorption method is deemed more suitable for defluoridation due to its usability, efficacy and economic viability. In these present investigations, the low cost agricultural materials as adsorbents were utilized for fluoride removal and also compared the efficiency. The experimental observations are discussed. We conclude that numerous human activities in the soil deliberate the release of toxic ion levels, which can lead to serious human health consequences for the environment. We recommend that the public health sector has taken appropriate action and organized more awareness camp related to health issues with the use of natural adsorbent materials for purification and removal as well.
