Biological Oxygen Demand. BOD is typically reported as 5 day BOD and ultimate BOD at 20 C and reported as milligrams of oxygen consumed per liter (mg O/L). BOD 5 is used by regulatory agencies for monitoring wastewater treatment facilities and monitoring surface water quality. BOD is the biochemical oxygen demand of the water and it is related to the concentration of the bacterial facilitated decomposable organic material in the water. A sample with a 5 day BOD between 1 and 2 mg O/L indicates a very clean water, 3.0 to 5.0 mg O/L indicates a moderately clean water and 5 mg O/L indicates a nearby pollution source. BOD is a laboratory test that requires an oxygen sensing meter, incubator, nitrifying inhibitors, and a source of bacteria.
