Groundwater Quality of Hisar City of Haryana State (India): Status of Fluoride Content

Sunil Kumar and Sanjay K Sharma

Fluoride is present mostly in every water source with varying concentration. In fact, fluoride is required for the growth of the body, and drinking water is the largest contributor to the daily intake of fluoride. Fluoride permissible amount in drinking water is 0.6 mg/l to 1.5 mg/l. High fluoride level in drinking water makes water unfit for drinking and causes dental and skeletal fluorosis, a major health problem. Many countries of the World including India have been facing this problem of excessive fluoride concentration. The present study is conducted with the objective of knowing the status of the fluoride concentration in groundwater of Hisar city of Haryana state (India). In the present study, the relation between various water quality parameters is also studied. These quality parameters under study are electrical conductivity, pH, total dissolved salts, chloride, fluoride and sulphate. The results show that the majority of the samples have amount of fluoride more than WHO standards. This is the main reason of dental and skeletal fluorosis in the population of the city. The study also reveals that water quality in the city was found unsatisfactory for drinking purposes without any prior treatment.
