BOD test is a simple and practical indicator of the total organic content that is available to organisms plus any chemicals that spontaneously react with oxygen. BOD test measures the oxygen consumed by microorganisms as they break down organic material The standard test for BOD is the five-day (BOD5) test carried out in the dark at 20 °C There is an indirect correlation between the BOD5 value and the level of organic pollutants.
