The aim of the present study was to assess the concentration of heavy metal in the groundwater samples in and around Dindigul town in summer and rainy seasons. Dindigul is situated in the southwest of the Chennai. Dindigul town does not have underground drainage system. The study area is facing the problem of water pollution because of various industries. Tanneries are thickly situated in and around Dindigul town. Forty groundwater samples were collected and subjected to heavy metal analysis. The results were compared with WHO standard. The result revealed that the mean concentration of Cu, Fe, Cr, Pb and Cd are within the permissible limit of WHO in most of the groundwater sampling stations in summer and rainy seasons. The mean concentration value of Zn and Mn exceed the permissible limit of WHO in most of the sampling stations. The groundwater samples were more polluted beside industrial area. The high level of chromium in some station is due to the discharge of effluents and solid wastes from tannery industries.
