What does turbidity measure in water quality?

Turbidity is a measure of how clear or cloudy water is due to the presence of suspended particles. These particles can include sediments, microorganisms, and organic matter, which scatter light and contribute to the overall cloudiness of the water. High turbidity levels can indicate poor water quality and can affect aquatic life as well as drinking water safety.

This measure is critical in water quality assessments because it can influence the effectiveness of disinfection processes and can also impact the health of aquatic ecosystems. Understanding turbidity helps in evaluating the physical characteristics of water, making it an important parameter in both wastewater management and potable water treatment.
