Consumer Confidence Reports (CCR) - section on EPA website

The Consumer Confidence Rule requires public water suppliers that serve the same people year round (community water systems) to provide consumer confidence reports (CCR) to their customers. These reports are also known as annual water-quality reports or drinking water quality reports. The remaining public water systems in the U.S. are not required to provide CCRs, because they do not serve the same people on a day-to-day basis throughout the year.

The CCR summarizes information regarding sources used (i.e., rivers, lakes, reservoirs, or aquifers) any detected contaminants, compliance and educational information. The reports are due to customers by July 1st of each year.

The site covers this information:

• Basic Information - Provides explanation of the purpose of the consumer confidence report rule and general information on the content of reports.
• Where You Live - Links to select drinking water systems' CCRs.

• Compliance Help - Provides guidance documents and materials to assist drinking water systems and primacy agencies with implementation of the CCR rule.
• Tools For Systems - Information tools to help drinking water systems prepare, distribute, and provide customers important information about their drinking water.
