Description:
Colored water problems originating from distribution system materials may be reduced by controlling corrosion, iron released from corrosion scales, and better understanding of the form and properties of the iron particles. The objective of this research was to evaluate the effects of a number of water quality parameters including sulfate, chloride, and orthophosphate, on the release of iron from an old cast iron pipe section removed from a drinking water distribution system, and to study the properties of the resulting suspensions. This project further developed the U.S. Environmental Protection Agency’s (EPA) understanding of water quality parameters and their effect on metals release in distribution systems. These results further enable EPA to provide expertise and guidance to water utilities, engineers, the general public and other stakeholders.
