Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 2
Abstract
Maintaining the quality of water is very essential in order to utilize the resource effectively. Rapid industrial and urban development’s often witness deterioration of water quality. It is important to assess the baseline characteristics of river water quality so that, sustainable development can be pursued. This study emphasizes on Cauvery River Basin, Tamil Nadu, India. Data has been collected for twenty years for different physiochemical parameters of water quality for about seventy five villages in Tiruchchirappalli district. Water Quality Index is a means to summarize large amounts of water quality data into simple terms for reporting to management and the public in a consistent manner. The Water Quality Index has been evaluated using Microsoft Excel for the parameters considered. The variables of interest are Total Dissolved Solids, Chloride, Sulphate, Bicarbonates, Nitrates, Fluoride, pH, Total Hardness, Calcium and Magnesium. The WQI obtained from the result ranged from 34.47 to 730.96. The analysis reveals that none of the villages have excellent quality of water. About 20% of the villages have moderately polluted water. In about 28% of villages, water is very poor and 52% of the villages have water which is unsuitable for drinking in Tiruchchirappalli district, Tamil Nadu, India.
