Discussion about Potential Distribution System Problems

Return to Distribution Systems Home Page
 
Water quality problems may occur at a distribution system as the result of changes to the ideal operation of that 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 (NAS) convened a committee to study 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. 
  • Public Water Supply Distribution Systems: Assessing and Reducing Risks: First Report (2005)
  • Drinking Water Distribution Systems: Assessing and Reducing Risks (2006)
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.
