- Turbidity is the cloudiness of the water and is caused by a large number of particles that are generally invisible to the naked eye, just like smoke in the air.
- Turbidity is an important measure of water quality.
- Increased cloudiness may come from biological particles such as plankton, sediment in the water, or other types of contamination such as dust or chemical particles.
- Turbidity is measured in FTU (Formazin Turbidity Unit).
