The five-day biochemical oxygen demand test is an empirical test used in standard laboratories to measure organic load and thus pollution strength in effluents and polluted waters. This study investigated the functional relationship between BOD5 and some quality parameters of surface water such as Chemical Oxygen Demand (COD) and Permanganate Value (PV) obtained from Omadino River in Warri, Delta State, Nigeria. The aim was to provide a quick evaluation of BOD5 for effluent monitoring. The linear regression equations and correlation established were: BOD5 = 1.20 PV + 0.25; r = 0.708 and COD = 9.38 BOD5 + 18.76; r = 0.900 respectively. Confidence intervals were: 0.77 ≤ a ≤ 1.64 at 95%; 0.56 ≤ a ≤ 1.84 at 99% for BOD5/PV and 9.23 ≤ a ≤ 9.53 at 95%; 9.16 ≤ a ≤ 9.60 at 99% for COD/BOD5. Results established strong relationship which will be useful for BOD5 prediction.
