Built to 40 CFR 141 + Title 22
Your California CCR, drafted against ~300 rules and ~1,700 data points.
14 federal SDWA rules, 32 California-specific requirements, 67 PHGs, 200+ verbatim EPA and state language blocks — all validated against your system's data to generate your Consumer Confidence Report.
Validation
Three validation layers. No unverified number ever published.
Forty automated checks across data integrity, narrative fidelity, and numeric provenance — every one running before your CCR is drafted.
Data integrity
Before the narrative is written
- LCRR 90th-percentile computed per 40 CFR 141.86
- RAA / LRAA averaging applied per EPA rule
- SDWIS facility-type filter (raw wells excluded)
- Federal vs. state MCL deltas flagged
Narrative fidelity
After the draft is generated
- Every MCL exceedance has a contaminant narrative
- EPA "typical sources" quoted verbatim for compliance
- Neutral, regulator-compliant phrasing as mandated by law
- Written in plain English
Numeric provenance
Before the CCR is delivered
- Every number traces to source data — SDWIS, EDT, or lab samples
- Allowed values: source data or published thresholds (MCL, MCLG, action level)
- Decimal precision matches EPA conventions (1–4 places)
- Validated against current data of record
Every number in your CCR traces back to SDWIS, EDT, or your lab.
The output
What regulators scan first.
A real page from a finished CCR — the water quality results table, generated from your utility's data and the encoded rules. Every contaminant, MCL, PHG, and typical-source line is required under 40 CFR 141 and California Title 22. Every one is on the page.
Behind LevelFlo.

LevelFlo began after months of reading California CCRs in their original form — Word documents, copy-pasted tables, hand-calculated averages. A document 2,732 CA utilities must publish every year, still assembled by hand. The data was already public; the gap was the tooling for a compliant, readable report.
Three commitments shape how LevelFlo is built:
- Data integrity. Every number traces to source data or legal value.
- Public trust. Language regulators require and ratepayers get.
- Focus. One problem, fully solved — no feature sprawl.
