This study aimed to evaluate the fluoride concentration in groundwater sources of Badhra Tehsil, Charkhi Dadri District, utilizing the ion-selective electrode method, and to assess the potential health risks associated with varying fluoride levels. Water samples were collected across 21 villages in the Badhra Tehsil during May 2023. These samples underwent analysis to determine fluoride concentrations, employing an ion-selective electrode method. The samples were collected from hand-pumps, wells, and tubewells, and were tested in a laboratory within 6–12 hours of collection. The fluoride concentration in groundwater samples ranged from 0.01 to 8.20 mg/ltr. While most villages had fluoride levels within safe drinking limits, the villages of Dagroli, Kakroli Hukmi, and Nimarh exhibited fluoride concentrations of 5.80 mg/ltr, 4.40 mg/ltr, and 8.20 mg/ltr, respectively substantially surpassing the WHO recommended limits and indicating a potential public health concern. However, the significantly high levels of fluoride in specific villages raise concerns for public health, necessitating immediate remedial actions such as the provision of alternative water sources, public awareness campaigns, and the introduction of defluoridation measures.
