Groundwater Quality Assessment of Some Blocks in Tannery Belt of Dindigul District, Tamilnadu

Industrialization is responsible not only for economic development but also for environmental pollution. Among the polluting industries, tanneries come under one of the most polluting industrial categories. There are more than 2500 tanneries in the country and nearly 1000 tanneries are located in Tamilnadu state alone. Out of these more than 80 tanneries are located in Dindigul district in Tamilnadu. The untreated effluents contaminate water and soil resources. At present both surface water and groundwater resources get depleted and polluted due to unscientific management and utilization. In the present study, the groundwater quality survey was carried out in Dindigul. The sampling points (wells) are located using GPS. The samples of groundwater were collected and analysed for 10 physicochemical parameters and the status of water quality is suggested using water quality index (WQI).
