    Significance and Use

    5.1 These test methods are used to chemically determine the maximum quantity of oxygen that could be consumed by biological or natural chemical processes due to impurities in water. Typically this measurement is used to monitor and control oxygen-consuming pollutants, both inorganic and organic, in domestic and industrial wastewaters.

    5.2 The relationship of COD to other water quality parameters such as TOC and TOD is described in the literature.3
