Aim: The main aim of the research is about the effects of variations of physical characteristics of water collected from a lake in Retteri. The water from the lake is characterized by extreme quantities of Total Dissolved Solids(TDS), pH, color, Turbidity and Suspended Solids. Materials and Methods: The pH was measured by pH meter. The Turbidity of the lake water sample was measured using a digital turbidity meter. The suspended solids was measured by using WHATMAN filter paper, the total dissolved solids was measured using TDS meter and the color of lake water was using integral spectrophotometer Results :The samples were analyzed and compared with the Indian standards of effluent discharge. The raw wastewater consists of pH of (6.4-6.7). total dissolved solids range from(883-840)mg/I, Turbidity ranges from(12.2-12.7) NTU, the color of lake water was (18- 21) Hz and suspended solids of (1500-1620)mg/I respectively. Conclusion: After the test it shows the pH and color of the Total Dissolved Solids. Suspended Solids, Turbidity were not in the permissible limits Standard Drinking Water.
