Hydrogeochemistry of Fluoride in Groundwater of Uravakonda,

Fluoride in drinking water has now become one of the most important geo-environmental and toxicological issues in the world. During the last three decades, high fluoride concentrations in drinking water sources and the resultant disease ¿Fluorosis¿ is being highlighted throughout the world. Andhra Pradesh, Rajasthan, Uttar Pradesh, Gujrat and Tamil Nadu being the states with the highest rating of endemic fluorosis. In Andhra Pradesh, several thousands of people in as many as 18 districts are suffering from fluorosis. Anantapur is one of the several affected districts where higher concentrations of fluoride have been found in the drinking water used by the people. In view of its physiological significance, the present study is aimed at to study the distribution and hydrogeochemistry of fluoride in groundwater of Urvakonda, mandals of Anantapur district of Andhra Pradesh.
