The carbonaceous and nitrogenous oxygen demand of Potomac River and STP effluent samples was determined during the summer of 1978. The oxygen depletion kinetics were studied during long term incubation using an inhibitor to nitrification. The average deoxygenation constants k sub e for the river sample CBOD and NOD were 0.12/day and 0.10/day, respectively. The CBOD of the Potomac STP effluent samples followed first order kinetics with an average k sub e = .16/day. The NOD for the STP effluent samples had a significant lag time resulting in poor correlation coefficients for first order fit. The average algal contribution to the BOD5 was 0.027 mg/micrograms chlorophyll a with 70% due to decay and 30% due to respiration.
