Specific water quality problems can occur in the distribution system. They occur as a result of changes to the ideal operation of a system. Discussion of these potential problems is provided below.
National Academy of Sciences Committee on Public Water Supply Distribution Systems: Assessing and Reducing Risks - At EPA’s request, the National Academy of Sciences convened a committee. The committee studied water quality issues associated with public water supply distribution systems. The Academy released two reports in 2005 and 2006. The reports and additional information on the study can be found at the NAS Web site. Exit

Distribution System Research and Information Collection Partnership Priorities - The Total Coliform Rule Distribution System Advisory Committee recommended that research and information collection priorities be developed concerning distribution system water quality. This led to the formation of the Research and Information Collection Partnership to identify priorities in a document.
