Results from a 2010 telephone survey indicate that more effective management of waterborne pathogens may be necessary at most US hospitals. Information about the quality of water obtained from municipal water supplies and groundwater wells varies depending on the condition of the source water and the treatment it receives (USEPA, 2010a). In the US between 1920 and 1990, 1118% of reported outbreaks of waterborne disease were attributable to distribution system contamination. Between 1991 and 1996, contamination of water in distribution systems was responsible for 22% of reported contamination outbreaks. There were 6,248 hospitals in the American Hospital Association (AHA) registry at the time of this research (AHA, 2010). Community hospitals were the largest single listing, with 4,897 entries.
