KSB 2: Turbidity Matters

What is turbidity?

• The color of the water

• The cloudiness or haziness of a fluid caused by suspended particles

• The temperature of the water

• The pH level of the water

Which unit is commonly used to measure turbidity?

• Liters

• Meters

• Nephelometric Turbidity Units (NTU)

• Grams

What effect does high turbidity have on aquatic plants?

• Increases photosynthesis

• Blocks light, reducing photosynthesis

• Reduced ability to find food

• Higher water temperatures

What can high levels of sediment in water indicate?
