Turbidity refers to the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye. The measurement of turbidity is a key test of water quality. High turbidity can have a range of negative effects on aquatic ecosystems. For example, it can block sunlight from reaching submerged aquatic plants, hindering their ability to grow. It can also settle on the bottom of water bodies, smothering the eggs of fish and other aquatic organisms.

Turbidity is typically measured in Nephelometric Turbidity Units (NTU). These units are determined by nephelometers, which measure the amount of light scattered by particles in the water. The higher the NTU value, the more turbid the water. Common causes of turbidity include suspended solids such as silt, clay, and organic matter, as well as plankton. Pollution from construction sites, agricultural runoff, and sewage discharge can significantly increase turbidity levels in natural waters. In drinking water treatment, turbidity is monitored closely as a crucial indicator of effectiveness and to ensure water is aesthetically pleasing and safe for consumption.
