Abstract
Physicochemical characteristics of groundwater samples of Dindigul town were studied by taking 20 groundwater samples at different stations. The aim of the present study is to analyse the physicochemical parameters for groundwater samples in summer and rainy seasons for three successive years. The results were compared with WHO standard. The obtained result revealed that the parameters such as EC, TDS, HCO_3, 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.
