Turbidity

 

Turbidity is a measurement use to define the clarity of water. Turbidity changes in water are normally attributed to the suspension of particulate material such as silt, soil or waste material which leads to the water becoming opaque or murky in appearance.

 

Turbidity measurement is very common in both natural environments, where it can lead to problems with vegetation growth or lead to the introduction of pesticides or chemicals through surface runoff. Turbidity is also measured in the waste water and drinking water environment, here turbidity is commonly monitored as part of a quality check or to meet discharge regulations / limits.
