What does turbidity in water refer to?

Turbidity in water specifically refers to the cloudiness or haziness of a liquid due to the presence of suspended particles. These particles can include sediments, organic matter, algae, and microorganisms, which scatter and absorb light, making the water appear unclear. High turbidity can have adverse effects on aquatic life by reducing sunlight penetration, which disrupts photosynthesis in underwater plants and can lead to decreased oxygen levels in the water.

Understanding turbidity is crucial in water quality assessments, as elevated levels may indicate pollution or the disturbance of sediment in water bodies. Monitoring turbidity is essential for ensuring safe drinking water and healthy aquatic ecosystems.
