Cloudiness & Discoloration Issues
It isn’t just fixtures and appliances that can be discolored and stained.
Discoloration of water is another sign of impurities. Turbidity refers to the amount of small particles of solid matter suspended in water as measured by the amount of scattering and absorption of light rays caused by the particles. Turbidity blocks light rays and makes the water opaque.
Turbidity is measured in nephelometric turbidity units (NTU). Potable water should not exceed 0.5 NTU. Turbidity cannot be directly equated to suspended solids because white particles reflect more light than dark-colored particles and many small particles will reflect more light than an equivalent large particle.
Water Treatment
In most cases, water cloudiness and discoloration is a noticeable issue in bath water and at the faucet(s) where water is used for drinking. To clear up water used for bathing, treating water for the whole house or building is necessary. If cloudiness or discoloration of water is only an issue for drinking water, then it is best to treat water at the faucet where it is used.
