Abstract

Samples of domestic sewage obtained from an estate located in Warri, Nigeria were analysed for selected pollution characteristics viz:
Electrical conductivity (EC), Suspended Solids (SS), Dissolved Solids (DS), Total Solids (TS), Permanganate Value (PV), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).
Values of the characteristics obtained in both wet and dry seasons showed that EC ranged between 220.6 uScm-1 and 367.0 uScm-1, SS ranged between 200 mg/L and 380.0 mg/L, TS had values between 162.2 mg/L and 286.0 mg/L, BOD ranged between 163.7 mg/L and 220.7 mg/L and COD ranged between 286.2 mg/L and 355.6 mg/L. Analysis revealed that high values occurred during the wet season compared with low values in the dry season months.
Values of the pollution characteristics show that the water is polluted. Treatment before disposal or reuse is necessary so as to prevent health, and environmental pollution hazards.
