Turbidity, measured as NTU or FNU
Overview
Turbidity is a water-quality term that refers to the cloudy appearance of water and is caused by small
particles of suspended matter. Turbidity is measured by quantifying the amount of light scattered by
particles in the water. Although turbid water is not necessarily harmful, it can be an indicator of more serious
problems. Turbidity particles may adsorb other harmful contaminants. Turbidity particles known to be
harmful themselves include asbestos, lead, bacteria and viruses, and protozoan cysts such as Giardia
and Cryptosiporidium.
