A community water system should prepare its annual consumer confidence report from verified source, monitoring and compliance records using the current agency template. Confirm the reporting year, required content, customer delivery and certification deadlines with its operator and drinking-water authority. This production duty applies to community systems; it is different from a customer reading the report.
Which system and reporting year are covered?
Confirm that the supply is classified as a community water system. ADEQ's Consumer Confidence Report Rule page applies the annual report duty to community systems, not automatically to every commercial noncommunity well. The required report summarizes source water, detected contaminants, compliance and educational information for customers.
Identify the previous calendar year's reporting period and collect the system's monitoring results and compliance records. If the system buys water from another community supply, coordinate the supplier information needed for its own report. A commercial private-well classification is a separate decision from producing the annual report.
The source-water assessment and protection guide explains the source-susceptibility record behind assessment information. That planning record does not prove present faucet-water quality or replace the annual report’s monitoring data.
The customer's water-quality-report guide explains interpretation. This checklist addresses the owner's preparation, delivery and certification work.
How should the content be verified?
Use ADEQ's current template and required explanatory language. Check system identification, sources, reported units, detected-contaminant values, relevant limits, monitoring periods, violations and the public-health explanations against actual records. Have the responsible operator resolve unexplained values instead of copying a previous year's table unchanged.
The AZSDWIS lookup guide helps locate available public sample and violation records for the correct system. Resolve any discrepancy with the responsible operator and authority; copying a database row does not independently verify the report’s required content.
ADEQ's published update identifies revised lead information, unresolved significant deficiencies and specified contaminant footnotes among content changes. Its page also announces additional changes beginning in 2027. Confirm the rules and template for the report being prepared; do not apply a future procedure as though it already governed the current reporting cycle.
Keep the separate service-line material inventory and its compliance phase consistent with the system’s lead-related records and required communications. The inventory describes piping materials; publishing the annual report does not complete every inventory or notice duty.
A sanitary-survey finding or a public-notice requirement should be reconciled with the report's compliance information. The annual report does not replace an urgent notice with a shorter deadline.
Which delivery records belong in the file?
ADEQ currently lists July 1 for distributing the previous year's report to customers and the state or local primacy agency. It lists proof of distribution by October 1 or 90 days after customer distribution, whichever comes first. A selling community system has a separate April 1 information-delivery duty to a buying community system.
Confirm the permitted delivery arrangements for the system rather than assuming posting a website alone reaches every required customer. ADEQ's mailing certification records direct delivery and good-faith efforts. Preserve the final report, recipient methods, distribution dates and submitted certification, and make copies available upon request as required.
If a deadline or content problem is discovered, contact the authority promptly and document the correction. A completed draft or repaired equipment does not itself satisfy report distribution or certify the accuracy of missing records.
