The correct answer is: Extent which water is polluted with organic compounds
To measure water pollution, the BOD test is made. In this test, the amount of oxygen sufficient to degrade waste organic matter by bacteria in a sample is measured. The more oxygen used up by the bacteria to degrade the organic matter in ample, the greater the BOD would be.
