ABSTRACT This study uncovered possible impacts of discharging raw sewage into the lagoon on the lagoon ecosystems and man in particular. The result of physiochemical and microbiological tests carried out on fish and sixteen water samples taken from Iddo in Apapa Local Government of Lagos State, Nigeria revealed pollution. E,coli, Proteus sp., Enterobacter sp., Aeromonas sp., Klebsiella sp., and Salmonella sp. were isolated microorganisms identified in the samples. The quantity of Total Solid (802-2711ppm), Dissolved Solids (550-1990ppm), Biochemical Oxygen Demand (59-140ppm), Level of conductivity (120-500µS), colour (5- 10HU), and Nitrate (23-65ppm) found in the water samples also confirmed that the Lagoon environment is insalubrious. Finally, conclusion was drawn with the recommendation that sewage should be treated prior to discharge into any sphere of the environment.

1.1 INTRODUCTION Waste, either solid or liquid, is an integral part of man. Its generation and efficient management
