The Science page explains the model. This page shows its review status.
Adding PFAS requires more than listing new packages. The benchmark library, reporting-limit logic, severity rules, and critical overrides must be updated for the specific PFAS analytes and methods.
What is ready—and what still needs sign-off
This is a transparent development checklist, not a claim that the Auraven Grade has already been independently validated.
Drafted
The Science page explains weighting, ratios, penalties, nondetects, multiple findings, and critical-result safeguards.
Added
EPA 537.1 (18 analytes), EPA 533 (25 analytes), and EPA 1633 (40 analytes) are identified with method-specific MDL and RL values supplied for the package tables.
Expert review required
Each PFAS analyte needs a selected comparison value, source, jurisdiction, effective date, legal status, and sensitive-population note. A single benchmark cannot be assumed for the entire class.
Expert review required
EPA 537.1, 533, and 1633 differ in scope and reporting limits. Nondetect interpretation must consider whether the RL is below the selected benchmark for that analyte.
Expert review required
PFAS severity factors, class-based aggregation, double-counting controls, and any mixture approach must be justified and documented.
Expert review required
Define when an individual PFAS result or combination limits the maximum Health score, overall grade, or action level.
Required before launch
Have qualified toxicology/public-health and South Carolina legal reviewers approve the claims, disclaimers, referral rules, and customer-facing interpretation.
