All are correct with respect to BOD (Biochemical oxygen Demand), except
1. It refers to the amount of oxygen that would be consumed if all the organic matter in one liter of water were oxidized by bacteria
2. The BOD test is a measure of the organic matter present in the water
3. The greater the BOD of waste water, less is its polluting potential
4. Waste water is treated till BOD is reduced significantly
