Which items must be included in a CCR?

The main thing a Consumer Confidence Report is designed to do is give the public a clear picture of how the drinking water performed in the last year, including what was detected, how it compares to regulatory limits, and any actions or health context the public should know. The best answer reflects that by including the detected regulated contaminant levels and the limits they are measured against (MCLs and MCLGs), plus any violation notices if standards were exceeded. It also covers variances or exemptions granted to the system, which explain any approved deviations from standard requirements. In addition, it mentions results for unregulated contaminants that were tested, so readers understand what was measured beyond the regulated list. Including key EPA definitions helps readers interpret terms like MCL and MCLG and grasp the report’s language. Taken together, this combination provides a complete, understandable view of compliance, public health information, and the system’s testing scope. Other options fall short because they omit essential elements. Focusing only on regulated levels and MCLs/MCLGs leaves out violations, variances/exemptions, and unregulated contaminants. Relying on sampling locations and QA/QC procedures is more about how the data was generated than what the public needs to know about water quality and safety. Reporting only violation notices or only variances/exemptions omits the full context of contaminant data and regulatory status.
