Methodology
The Home Safety Score (0-100) combines four data dimensions: EPA water violation history, lead exposure risk from infrastructure and sampling data, county-level EPA radon zone classification, and FEMA flood claim records. A score of 99-100 indicates minimal risk across all dimensions.
Data sources: EPA Safe Drinking Water Information System (SDWIS), FEMA National Flood Insurance Program, EPA radon zone maps, EIA electricity rates, and Consumer Confidence Reports. Last updated: 2026-06-04.
