Water Supply Systems - Impurity Limits
Typiclal limits for impurities in drinking water.
Typical limits for impurities in water supply systems:
Impurity | Limit (ppm) |
---|---|
Color | 20 |
Copper | 3.0 |
Fluoride | 1.0 |
Hardness, Ca and Mg salts | 100 |
Lead | 0.1 |
Magnesium | 125 |
Iron plus manganese | 0.3 |
Solids | 500 |
Turbidity | 10 |
Turbidity is is an optical characteristic and a the measure of the relative clarity of a liquid. It is a measurement of the amount of light that is scattered by material in the water when a light is shined through it. High intensity of scattered light equals to high turbidity.
