The present investigation is centered on the Physicochemical characteristic features in water samples collected from the Puliyanthangal lake of Ranipet region which is suspected to be influenced by the intrusion of tannery effluents and domestic waste by direct and indirect means. Monthly water samples were collected at station 1 and station 2 from the Puliyanthangal lake of Ranipet area for the period of one year from May 2016 to April 2017. The range of physio-chemical parameters such as appearance (turbid/clear), colour (colourless/green), odour (none), total dissolved solids (265-1553), turbidity (0.9 - 13.17 ), electrical conductivity (76-782 Mhc), PH (6.85-7.93), dissolved oxygen (4.73-22.50 ), calcium (46.33-152), magnesium (12.10- 36.33), sodium (211-296), potassium (0.30-24.26), iron (0.02-0.49), manganese (0.01-0.29), free ammonia (0.04-1.14), nitrite (0.01-1.37) nitrate (6-41), sulphate (19.5-234) and phosphate (0.03-3.88) were recorded and discussed. Unit of the chemical parameters is represented as mg/l and physico-chemical parameters were estimated using the standard method of APHA (2005). The data was analyzed using two way ANOVA. However, escalation of physicochemical variables was noticed only in sampling station 1 and this may be due to the entry points to receive the high amount organic load from the discharge of tannery effluents and domestic wastes by direct or indirect means. It is suggested from this study that these biotopes are to be conserved from the intrusion of pollutants so that the biodiversity of the ecosystem would be sustained.
