Abstract
The purpose of the present research was to assess the fluoride concentration of the groundwater in the Charkhi Dadri Tehsil and Baund Kalan Sub Tehsil of Haryana, which serves as the areaâs main supply of drinking water. One hundred eight groundwater samples were collected either from handpumps, tubewells or wells and were tested for fluoride content. Fluoride concentrations ranged from 0.01 mg/l to 8 mg/l in Charkhi Dadri Tehsil, and the fluoride concentration of 9 out of 21 villages was found to be under 0.7 mg/l. In Baund Sub-tehsil of Charkhi Dadri District in Haryana. All 21 villages in Baund Sub-Tehsil of Charkhi Dadri district had fluoride levels that were below the WHOâs highest admissible limit of 1.5 mg/l; however, Fluoride levels in 11 out of 87 villages/towns exceeded the permissible level in Charkhi Dadri Tehsil of Charkhi Dadri District, making them inadequate for drinking. Furthermore, skeletal and dental fluorosis is at an alarming level among nearby residents in these areas. The principal origins of fluoride in groundwater are assumed to be the abundance of fluoride-bearing minerals in the host rock, along with chemical characteristics like dissociation, dissolution and decomposition, in addition to their interaction with water. The suggested disciplinary measures to minimize fluoride contamination include dilution by blending, effective irrigation practices, artificial recharge and construction of well.
