Contaminant Level (MCL)
|Convential or Direct Filtration||1 NTU (Nephelolometric Turbidity Unit)|
|Other Methods||5 NTU (Nephelolometric Turbidity Unit)|
Turbidity is the measure of water clarity—the cloudiness of water—caused by suspended solids. The EPA lists these common sources:
Turbidity itself has no adverse health effects, but can potentially feed and shelter harmful pathogens and interfere with other water treatment methods.
Treatment for turbidity varies depending on the amount and nature of the particles present. A series of filters may be necessary, beginning with a sediment filter to remove larger particles.
