MEDOAbstract Water Quality Index is one of the most powerful and effective tool for analyzing the overall characteristics of water quality and monitor water pollution in any areas and transfers information exactly on water quality trends to policy makers and to the general public. Water quality indices are useful for concise information in order to achieve a national perspective. Objective of this study was to evaluate and determine water quality index of Theni and Dindigul districts, Tamilnadu. A total of 79 samples were analysed using a weighed arithmetic index method to represent a clear scenario about the quality of water for drinking purposes. The indices have been computed for 2006 2015. This study also identifies the critical condition of water that affects the groundwater quality. It was found that the water quality ranges between excellent and unsuitable for drinking. The unsuitable river, dam, pond and bore well water needs to be treated before drinking. |
