Significance Of Iron And Manganese In Drinking Water
for iron is 300 µg/L. Above 300 µg/L, water will become a reddish-orange color. As the amount of iron in the water increases, the color deepens. A public drinking water supply cannot be required to supply water with iron below any particular level; however, systems are advised that iron over 300 µg/L will cause their water to be discolored.
