An Investigation Of Fluoride Distribution In Nawa- Makrana Zone Of Nagaur District, Central Rajasthan, India And Defluoridation Of Water From Plant Material.

Abstract

This study focuses on groundwater fluoride contamination investigations in the Nagaur district's Nawa Makrana zone, where groundwater serves as the primary supply for irrigation and drinking. In the Nawa-Kuchaman zone, 31 communities provided groundwater samples, 10 of which had fluoride amounts over the safe drinking water threshold of 1.5 mg/L. The results show that 10 of these villages have groundwater that is not suitable for consumption because of high fluoride levels. Areas of concern were outlined in a fluoride concentration map for the region. The fluoride concentration was highest in Piprali village (5.8 mg/L); and lowest in Bawali Guta (0.3 mg/L). A low-cost defluoridation technique using plant-based materials was employed to mitigate health risks associated with high Fluoride levels. Fluoride concentration in treated samples was reduced to the acceptable range (0.5 – 1.5mg/L) meeting drinking water quality standards. The importance of the development of efficient, low-cost methods of fluoride removal in affected areas is highlighted by this study.
