Biochemical oxygen demand (BOD) is a crucial environmental index used to estimate the relative oxygen requirements of wastewater, effluents, and polluted water. It refers to the quantity of oxygen required by bacteria and other microorganisms in the biochemical degradation and transformation of organic matter under aerobic conditions. The BOD is also interpreted as a measure of the concentration of organic material that can serve as a substrate to support the growth of microorganisms.

| Definition | Biochemical oxygen demand (BOD) is a measure of the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria. |

| Purpose of treatment | One of the main reasons for treating wastewater prior to its discharge into a water resource is to lower its BOD—i.e., reduce its need of oxygen and thereby lessen its demand from the streams, lakes, rivers, or estuaries into which it is released. |

BOD measures the oxygen required to remove waste organic matter from water
The biochemical oxygen demand (BOD) is a crucial environmental index for determining the relative oxygen requirements of wastewater, effluents, and polluted water. It refers to the quantity of oxygen required by bacteria and other microorganisms in the biochemical degradation and transformation of organic matter under aerobic conditions. The BOD is also interpreted as a measure of the concentration of organic material that can serve as a substrate to support the growth of microorganisms.
BOD measures the amount of oxygen required to remove waste organic matter from water in the process of decomposition by aerobic bacteria. The more organic matter there is (e.g., in sewage and polluted bodies of water), the greater the BOD; and the greater the BOD, the lower the amount of dissolved oxygen available for higher animals such as fishes. The BOD is therefore a reliable gauge of the organic pollution of a body of water.
The BOD test was originally devised by the United Kingdom Royal Commission on Sewage Disposal as a means of assessing the rate of biochemical oxidation that would occur in a natural water body to which a polluting effluent was discharged.
The BOD is an empirical test, in which standardized laboratory procedures are used to estimate the relative oxygen requirements of wastewaters, effluents, and polluted waters. The five-day incubation period has been accepted as the standard for this test (although other incubation periods are occasionally used).
Determining how organic matter affects the concentration of dissolved oxygen in a stream or lake is integral to water-quality management. BOD is used, often in wastewater-treatment plants, as an index of the degree of organic pollution in water.

The BOD is an empirical test, in which standardized laboratory procedures are used to estimate the relative oxygen requirements of wastewaters, effluents and polluted waters. Microorganisms use the atmospheric oxygen dissolved in the water for biochemical oxidation of organic matter, which is their source of carbon. The BOD is used as an approximate measure of the amount of biochemically degradable organic matter present in a sample. The five-day incubation period has been accepted as the standard for this test (although other incubation periods are occasionally used).
