Turbidity is measured in nephelometric turbidity units, or NTUs. Nephelometric simply means how cloudy the water is. The picture above shows different NTU values for samples of water. Drinking water must have less than 0.5 NTU, more clear then the beaker of water shown above with a 10 underneath.urbidity is a measure of how clear the water is. High turbidity means that there are a lot of particles suspended in the water and light cannot get through. Low turbidity means that there are fewer particles in the water and it is more clear. Turbidity in a stream may increase from: 1  soil erosion. 2  higher levels of algae.
