Analysis of Ambattur Lake Water Quality with Reference to Physico ? Chemical aspects at Chennai, Tamil Nadu

Drinking water is contaminated through the pipe distribution system of directly through ground water due to addition of waste discharged from domestic, industrial and agriculture sources. The present study was designed to assess the nature and Physico-chemical characteristic of water samples collected from in and around Ambattur Lake, Chennai, Tamilnadu. The Physico-chemical parameters such colour, pH, odour, Biological oxygen demand (BOD), Chemical oxygen demand (COD), Calcium, Hardness, Alkalinity, chloride, Nitrate and magnesium were studied. The results obtained showed a fluctuation in this parameter-s which gave an idea about the intensity of pollution caused by industrial which is largest area in Asia and also manmade activities. In the present study revealed that the lake water was alkaline. The chloride and hardness concentrations were high. The water quality was found to be hard which was due to excess of calcium and magnesium ions present in lake water in excess quantity. Every parameter showed a significant correlation with increased lake water pollution. The determined Physico-chemical parameters were compared with the BIS and ICMR standards for the drinking water to know about the quality of the groundwater.
