Question: 1 / 400

What does increased turbidity in water indicate?

Lower levels of nutrients

Higher levels of sediment

Increased turbidity in water indicates higher levels of sediment. Turbidity itself is a measure of the cloudiness or haziness of a water body, which is primarily caused by the presence of suspended particles such as soil, silt, and organic matter. When sediment levels in water increase, they scatter light and contribute to increased turbidity.

This condition can arise from various sources, including runoff from rainfall, disturbed soil areas, and erosion. High turbidity is significant because it can impact aquatic ecosystems, affect the growth of aquatic plants, impair the ability of organisms to find food, and hinder the effectiveness of disinfection processes in water treatment. Consequently, understanding turbidity and its implications helps in assessing the overall health and quality of aquatic environments.
