ASSESSMENT OF FLUORIDE CONCENTRATIONS IN THE GROUNDWATER OF JHUNJHUNU, RAJASTHAN, INDIA REGION

Fresh water is a lifeline of all living organisms because freshwater is mostly stored in glaciers, rivers, lakes, and the underground of the earth. According to the ICMR standard, a 0.6 mg/l fluoride concentration is required for human teeth and bones while more than 1.5 mg/l fluoride concentration is responsible for various human diseases. All water samples of groundwater and deep wells have been collected from the Chirawa, Buhana, and Surajgarh of the Jhunjhunu district for the assessment of fluoride concentration. All water samples are analyzed through physiochemical methods. Fluoride concentration was determined with the help of the APHA-23nd 2017 method. The highest concentration of fluoride was found at 1.4 mg/l of Kakoda (Sample no 16) while the lower concentration of fluoride was found at 0.7 1.4 mg/l of three places as Pilani water box, Morva, and Chirawa CHC (Sample no 1, 10, 30). The fluoride concentration of the remaining places was found suitable for the human being.
