VI-6-Fluoride Content in the Groundwater of Dabwali.

Abstract

High concentration of fluoride in the groundwater of different parts of the world is responsible for widespread fluorosis. Haryana, a small state in India is one such region where high concentration of fluoride is present in groundwater. The objective of the present investigation was to determine the fluoride content in the ground water of Dabwali area of Sirsa district of Haryana, India. A total of fifty two groundwater samples were randomly collected at different depths from tube wells and hand pumps. The results showed that fluoride concentration in the ground water of Dabwali ranges from 0.90-34.50 ing/I with a mean of 2.20 ± 18.13 mg/1. Mostly people use groundwater for domestic and irrigation purpose, Therefore, the intake of fluoride concentration is very high as people using groundwater without any prior treatment. The results suggest that the groundwater should be used by the residents only after defluoridation.
