Turbidity is a measure of water clarity, as it is the observable characteristic of the extent that the suspended particles in the water impair the ability to see clearly through it. A nephelometer (Figure 2) is used in water treatment plants to measure turbidity, which measures light scattered within a section of water. In lakes, turbidity may be measured by use of a secchi disk (Figure 3), which is released into water until it can no longer be seen, at which point the depth of it is measured.

==Importance and Impacts==

===Water temperature===
High turbidity increases water [[temperature]] due to the particles absorbing [[sunlight]]. This is worrisome because higher temperatures of water result in less [[oxygen]] content, leading to [[hypoxia|hypoxic conditions]].<ref name=len>Lenntech. (Accessed September 19, 2015). ''Turbidity'' [Online], Available: http://www.lenntech.com/turbidity.htm</ref> Suspended particles also scatter light, preventing it from reaching plants and algae, thereby further reducing oxygen content. These higher temperatures lead to fish using ''more'' oxygen due to increased metabolic rates as well, limiting the supply even more so.<ref>Lenntech. (Accessed September 19, 2015). ''Why oxygen dissolved in water is important'' [Online], Available: http://www.lenntech.com/why_the_oxygen_dissolved_is_important.htm</ref>

===Drinking water===

Knowledge of water's turbidity is important and is closely monitored in water treatment facilities. Most particles that contribute to turbidity are not harmful to humans upon ingestion, however their content in water is an indicator to other substances that do cause harm.<Ref>Health Canada. (Accessed September 19, 2015). ''Turbidity in Drinking Water'' [Online], Available: http://www.hc-sc.gc.ca/ewh-semt/pubs/water-eau/turbidity/index-eng.php</ref> Measurements of turbidity give an indication of how well the treatment processes are working and allow for optimal selection in treatment technologies.

See [[water quality degradation]] for more information on the effects of substances within water.
