Turbidity

Turbidity is a measure of the degree to which the water looses its transparency due to the presence of suspended particulates. 
The more total suspended solids in the water, the murkier it seems and the higher the turbidity. (http://www.lenntech.com/turbidity.htm) To sustain aquatic life, 1o day average should not exceed 25 NU/JTU and no reading should exceed 50 NTU/JTU
