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.You may need a PDF reader to view some of the files on this page.
