This work was carried on to evaluate fluoride contamination in ground water of the medial part of Nagaur district where ground water is the main source of drinking as well as irrigation. The current work involves assessment of water quality with special source to fluoride in nawa- makrana zone of Nagaur district. Fluoride concentration of groundwater samples from thirty one villages of nawa- kuchaman Zone was took over and 10 villages were set up to have a fluoride attention above1.5 mg/ l. The logical results show that ten ground water samples are unable for drinking purpose. A map has been prepared which shows the fluoride concentration in the study region. The outward attention was marked in the Piprali village(5.8 mg/ l) while the minimum was set up in Bawali guta(0.3 mg/ l). Water samples holding high fluoride situations were defluoridated with low- cost paraphernalia prepared from plant by products. These paraphernalia successfully drop the fluoride ions attention to an esteemed limit( from0.5 to1.5 mg/ L) without transferring drinking water quality standards.
