Seasonal Variations of Groundwater Quality in and around Dindigul Town, Tamilnadu, India

Dindigul is situated southwest of the state capital, Chennai. The 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. The pollution is affecting large numbers of people and causing a detrimental effect upon their health. The aim of the present study is to assess the physicochemical parameters for the groundwater samples in summer and rainy seasons. Twenty groundwater samples collected from borewells in and around Dindigul town and subjected to physicochemical analysis. The results were compared with WHO standard. The obtained result revealed that the parameters such as EC, TDS, HCO3, Cl, K, PO4, BOD, COD, and DO exceed the permissible limit of WHO in most of the groundwater sampling stations in summer and rainy seasons. The groundwater samples were more polluted beside industrial area.
