Consumer confidence reports are the centerpiece of the right-to-know provisions in the 1996 Amendments to the Safe Drinking Water Act. The Amendments contain several other provisions aimed at improving public information about drinking water, including the annual public water system compliance report (available from the Office of Drinking Water) and improved public notification in cases where a waterworks owner is not meeting a contaminant standard.
Every community waterworks owner must distribute a consumer confidence report annually by July 1 that contains information about the drinking water provided to its customers during the previous calendar year. The report must contain the following:
Consumer Confidence Reports Rule

Otherwise, customers may think that no samples for those important contaminants were collected. Fo
