Abstract

The present study deals with the study of physico-chemical parameters of lakes of silicon city, (Bangalore), India. Systematic calculation of correlation coefficient between water quality parameters has been done with the objective of minimizing the complexity and dimensionality of large set of data. The significant correlation has been further verified by using t-test. The water samples were collected and analyzed for three consecutive years 2003-2005. In the study an appreciable significant positive correlation was found in Byramangala lake for pH with BOD, temperature, alkalinity and total hardness (TH); conductivity with dissolved oxygen (DO), sulphate, nitrate, potassium and phosphate with nitrate, sulphate. A significant negative correlation was found for pH-DO, DO-BOD, TDS-turbidity, turbidity-sulphate, COD and DO-COD. In Hebbal lake significant positive correlation was found for temperature-COD, sulphate-nitrate, TDS-nitrate, TDS-conductivity, TH-alkalinity and significant negative correlation was found in temperature-DO, TH-potassium, DO-BOD, TDS-TH and in Yelahanka lake significant positive correlation was found for pH-temperature, BOD, COD, TDS-phosphate, TDS-potassium, phosphate-sulphate, conductivity-phosphate, conductivity-nitrate and potassium, TH-BOD, COD and significant negative correlation was found in pH-turbidity, pH-DO, temperature-turbidity, turbidity-TH, COD and conductivity-TH. The results revealed that most of the water samples were below or out of limited according to the WHO and BIS standards.
