Abstract

The Present study was conducted in January 2010, in order to assess the fluoride contamination in the Thirupathur Taluk. The major objective of this study was to locate the vulnerable areas in terms of fluoride contamination. The range of fluoride concentration varied between .26 and 2.75 mg/L. 60 % of the samples were above the permissible limit. Good correlation was observed between pH, Na, HCO(3), CO(3) TDS and NO(3). A negative correlation showed by Ca and K. The results show that Geochemistry of these ions controls the Fluoride concentration in the study area. All the samples exceeded the permissible limit of F was characterized by Na-HCO(3) type of water. A fairly good correlation between F and NO(3) suggest an anthropogenic input of F, mainly from the agricultural fields. Spatial distribution map of Fluoride shows very high concentration in the SW part of the study area.
