Abstract

Water is an inorganic solvent and covers about 70% of the earth’s surface. Quality and quantity of water are affected by an increase in anthropogenic activities and any pollution either physical or chemical which causes change to the quality of the receiving water body. Water samples were collected at three locations along Ase creek and analyzed for temperature, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) using standard methods. Results obtained ranged as follows: 26 - 28?C for temperature; 6.48 - 6.75 for pH; 6.50 – 8.50 mg/l for DO; 0.50 - 1.50mg/l for BOD; 1.50 -2.50mg/l for COD. The pH values for the water samples were slightly acidic. The BOD/COD ratios for all the sampling points were less than 1 indicating that the water samples have a biodegradable nature. The results obtained were within WHO permissible limit for drinking water except DO. There is thus the need to examine periodically water quality parameters of water bodies prior to use in order to ensure that they are free from organic and other pollutants. This in the long run will help to promote a healthy condition needed for sustainable development.
