WebED Education, Outreach and TrainingA Short Course: Using Modeling and StatisticsHypothesis of Dissolved Oxygen vs. BOD As the BOD goes up, the dissolved oxygen should go down. This is because the decomposition of organic waste requires bacteria. Those bacteria use dissolved oxygen for their respiration. The more BOD, the more bacteria. Since the amount of oxygen dissolved in the water is only replenished slowly by interaction with the air, a large BOD load will cause the levels dissolved in the water to go down for a time.
