TO EVALUATE THE SIGNIFICANCE OF GROUND WATER IN RURAL AREAS IN BILASPUR WITH PARTICULAR REFERENCE TO FLUORIDE ATTENTION
Fluorine is a common element that does not occur in the elemental state in nature because of its high reactivity. Fluoride is a key aspect of water quality in rural water supply systems, which potentially affects the sustainability of water if it exceeds its prescribed limit. Excess intake of fluoride through drinking water causes fluorosis in human beings in many states of India, including Chhattisgarh .This study aims to identify the hydro geochemical processes influencing the high fluoride concentration in ground water of rural areas of Bilaspur (Chhattisgarh, India). For this purposes ten ground water samples were collected during the post monsoon session of 2010. The fluoride concentration in ground water was determined, where it is the only source of drinking water. The fluoride concentration was determined SPANDS method. In this method fluoride concentration was determined spectro-photometrically by using acid Zirconyl and Sodium -2 para sulfophenyl azo -1, 8 dihydroxy -3, 6-napthalene disulfonate (SPAND) reagents. The fluoride concentration in the ground water of these villages varied from 0.73 to 3.02 mg/L, causing dental fluorosis among people especially children of these villages. Overall water quality was found unsatisfactory for drinking purposes without any prior treatment except few villages. Most people in these study areas suffer from dental fluorosis and skeletal fluorosis such as mottling of teeth, deformation of ligament, bending of spinal column and premature ageing.
