The amount of dispersed suspended solids in natural water bodies is an important indicator of water quality. These solids that often include silt, clay, algae, organic matter, and other minute particles, obstruct the transmittance of light through the water and impart a qualitative characteristic known as turbidity. Turbidity is often closely correlated to climatological or surface water conditions and changes in turbidity are therefore indicators of changes in environmental conditions.
“Turbidity data can be used as a surrogate measurement because it is strongly correlated with sediment, nutrients and bacteria, and can be measured in-stream on a continuous basis.”
