Description:
Colored water" describes the appearance of drinking water that contains suspended particulate iron although the actual suspension color may be light yellow to red depending on water chemistry and particle properties. The release of iron from distribution system materials such as cast iron water mains is a complex process involving mass transfer and many interactions including corrosion and oxidation-reduction, precipitation and dissolution, solid phase reactions, microbiological activity, and is most greatly influenced by water chemistry.
