摘要：High fluoride in groundwater is a major toxicological and geoenvironmental issue in India. The area selected for study, the Salem district, Tamilnadu State, India, has endemic fluorosis. To determine the geochemistry of fluoride in the local groundwater, samples were collected from major lithological units in the study area (peninsular gneiss and charnockite) and analyzed for fluoride using standard procedures for two seasons, the pre- and post-monsoon. Higher fluoride was noted in the post-monsoon season in both charnockite (4.02 mg/l) and peninsular gneiss (2.85 mg/l), indicating the ability of rainwater to dissolve greater concentrations of fluoride to groundwater from the aquifer matrix. Correlation and factor analysis confirms fluoride leaching from the aquifer matrix. Modeling results support the field observations.
