ABSTRACT

The present study was designed to assess the nature and physicochemical characteristic of water samples collected from in and around Pulliyankannu Lake, Ranipet, Vellore Dt., Tamilnadu. The physicochemical 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 and tannery effluents. In the present study revealed that the lake water was alkaline. The chloride and conductivity concentrations were high. The water quality was found to be hard which was due to excess of calcium and magnesium through surface run-off. 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.

Keywords: Pulliyankannu lake, Vellore, groundwater, water pollution.
