Turbidity is typically measured in what units?

• A. Nephelometric Turbidity Unit
• B. Milligrams per liter
• C. pH
• D. Colony-forming units per milliliter

Answer: (A)

Turbidity is about how cloudy water is due to suspended particles that scatter light. A nephelometer shines light into the water and measures the light that is scattered, typically at a 90-degree angle. The reading is given in Nephelometric Turbidity Units, the standard unit for expressing turbidity. This unit specifically reflects light-scattering properties caused by suspended solids, which is different from just how much material is present by weight. In contrast, milligrams per liter measures mass concentration of solids, pH measures acidity, and colony-forming units per milliliter counts viable microbes. So the unit that best describes turbidity is the Nephelometric Turbidity Unit.
