Abstract
A tremendous increase in the demand for freshwater due to rapid growth of population, urbanization and the accelerated pace of industrialization act as a main driving force for altering local and regional hydrology. It is noted that in Tamil Nadu, there is evidently much dependence on groundwater due to scarce surface water. Overexploitation of groundwater might lead to complex environmental situation. Hence, a thorough investigation of quality parameters is necessary to ensure the portability of water. The objective of the present study is to analyze the various parameters of ground water and to assess the quality of ground water using water quality index for the region of Karayanchavadi in Chennai, Tamil Nadu, and India. The study area has been categorized as Residential, Residential with Part Industry, and Residential with Part Crop Cultivation area and Crop Cultivable area. Groundwater samples were collected from each zone for two years duration and analyzed for physico-chemical parameters following standard methods and procedures. The results obtained are compared with WHO standards. The results of the study reveal that most of the parameters in the study area are within the permissible limits. Water Quality Index suggests that water is suitable for domestic purposes.
