Identify the record
Analyte, canonical slug, original value and unit, detection limit, lab, method, date and location.
Evidence architecture
Methodology
H2Optic’s authority should come from traceable sources, explicit reference types and careful language—not from a proprietary score.
Measurement first. Context second. Conclusions with limits.
We keep raw reported values and units, normalize a copy for comparison, and preserve the origin, method, reporting limit, date and sampling context.
This first pass establishes the architecture. Factual records require source-level editorial review and live citations before production publication.
Match references
Federal regulation, state standard and health reference are stored separately, each with authority and effective date.
Explain evidence
Established finding, regulatory standard, association, emerging evidence or unresolved / insufficient evidence.
Source hierarchy
Primary sources lead.
- Primary
- EPA, CDC, NIH, USGS, state environmental and health agencies, and peer-reviewed research.
- Secondary
- Major universities, recognized research institutions and reputable scientific reviews.
- Not primary
- Affiliate companies, filter manufacturers and marketing blogs do not establish health conclusions.
Unit architecture
Original units are never discarded.
The model anticipates mg/L, µg/L, ng/L, ppm, ppb and ppt. Conversions require analyte-aware assumptions, recorded precision and a visible normalized unit. “Parts per” shorthand and mass-per-volume values are not silently treated as identical in every context.
