A real, published Consumer Confidence Report
Look at a CCR drafted by the agent — every required section, every compliance check, every byte-exact EPA verbatim block.
Your 2026 CCR is due July 1. Here is the 6-week plan.
The Consumer Confidence Report deadline is non-negotiable. Here's the week-by-week operator plan to be done well before July 1 — and the specific deliverables each week should produce.
ppb vs mg/L: the unit pitfall that fails one in five CCRs
Unit conversion errors are the single biggest reason state reviewers kick reports back. Here's why mixing ppb with mg/L happens, what the federal rule actually says, and how to make sure it doesn't fail your CCR.

Orange City, Indiana — early-access pilot
A mid-size community water system using 1water.ai through the 2026 reporting cycle. Early-access means everything they publish through us is mirrored to a state-program reviewer for validation. No published rejections.
Star Valley, Wyoming — small-system early access
A rural small community water system with one licensed operator and a spreadsheet-based workflow. The team moved from a week of CCR work to an afternoon, with every calculation tied back to its source lab PDF.
2026 CCR deadline — a 45-minute walkthrough
What July 1, 2026 actually requires of your utility. Live deliverable checklist, common state-rejection patterns, and Q&A with our regulatory team.
