The amount of oxygen required by bacteria to break down the organic matter present in a certain volume of a sample of water is called BIOCHEMICAL OXYGEN DEMAND (BOD). Which of the following statements are correct ?

A

The amount of BOD in the water is a measure of the amount of organic material in the water, in the terms of how much oxygen will be required to break it down biologically.

B

C

Clean water would have BOD value of less than 5 ppm whereas highly polluted water could have a BOD value of more than 17 ppm.

D

Clean water and polluted water both have BOD value of 5 ppm.
