Data Fields
Key fields per ZIP code:
- Home Safety Score 4.0.0: published only when all four required inputs are present; four inputs are grouped into three equally weighted domains
- Violations: total, health-based, monitoring/reporting
- Lead: typed measurement evidence where available
- Copper: action-level exceedance flag only; no concentration is published because the source does not provide a verified unit
- PFAS: detection status, levels where available
- Radon: EPA zone classification
- Historical NFIP Claims: claim records are not current FEMA property-map coverage
- Demographics: population served, median home value, housing age
Retired Legacy Artifact
The legacy ccr-enriched.csv companion file was retired on 2026-08-19. Its ccr_copper_90th_ppb column mixed mg/L and ppm source values under a ppb label, understating some copper values by 1000x. Use copper_action_level_exceedance in the current dataset. No unverified copper concentration is published.
