Turbidity, one of the important water quality parameters, is measured in
AColour units
BPH units
CNTU ✓ Correct
DMicrogram per cubic metre
Correct answer: (C) NTU — Turbidity is measured in NTU, so the answer is NTU.
Explanation
★Turbidity is measured in NTU, so the answer is NTU.
★Turbidity measures how cloudy or hazy water is due to suspended particles.
★It is assessed by how much light the particles scatter.
★The unit for this is the Nephelometric Turbidity Unit, or NTU.
★The more the light is scattered, the higher the turbidity in NTU.
★PH units and colour units measure other water properties.
★So turbidity is measured in NTU.
