Introduction: Drinking water having High concentrations of fluoride (F–) are harmful to human health. For taking adequate preventive measures the knowledge of spatiotemporal distribution of F– content in groundwater is thus a prerequisite.

Study Setting & Location: This study was conducted to find out the fluoride incidence in groundwater and its relation with the prevalence of fluorosis in Yavatmal and Chandrapur district of Vidarbha Region of Central India.

Results: Nearly 18% of the sampled wells had fluoride concentrations above the desirable limit (> 1.0 mg/l), the highest value being 8.8 mg/l. High fluoride concentrations primarily occurred in (REGIONS of YAVATMAL & CHANDRAPUR. Prevalence of dental fluorosis was observed in five villages in Chandrapur District and 2 villages in Yavatmal district whereas skeletal fluorosis was found to occur in two Villages of Chandrapur district. Among the 416 subjects surveyed 41 (17.86%) and 23 (16.33%) subjects had signs and symptoms of either dental or skeletal or both types of fluorosis. The spatial distribution of fluoride in groundwater, as indicated by hydrogeochemical analyses, corroborated well with the prevalence of dental and skeletal fluorosis. It is envisaged that, in addition to the people already affected, a large fraction of the population in the area is at potential risk, especially considering that the region falls in the coal mining and industrial belt. The health-risk map prepared using a Geographic Information System provides baseline information in taking mitigation measures.

Conclusion: Parts of the districts are affected by the high fluoride concentration in ground water and therefore the utilization of water from phreatic aquifers will minimize the incidence of fluorosis in the endemic areas as deeper aquifers are discharging fluoride contaminated ground water. A multi-sectoral approach is needed to study the ground water development augmentation and management perspective. Therefore, all the aspects related to conjunctive use, ground water legislation, involvement of NGO, woman and community participation, mass awareness campaign, selection of appropriate pump sets, adoption of new irrigation methods, tissue culture technology will play an important role in conserving and developing the precious water resources.
