Methodology

The Environmental Justice Index combines environmental risk factors (water violations, lead, flooding) with socioeconomic vulnerability indicators. Higher values indicate communities facing disproportionate environmental burden. This metric highlights areas where infrastructure investment and policy attention are most needed.

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: 2026-04-13.

Frequently Asked Questions

What is the Environmental Justice Index?

The EJ Index identifies communities that face disproportionate environmental hazards relative to their socioeconomic resilience. Areas with high violation counts, aging infrastructure, AND vulnerable populations score highest. These areas need the most infrastructure investment.

Why does environmental justice matter for homebuyers?

High EJ Index areas often have deferred infrastructure maintenance, slower violation resolution, and less access to clean water alternatives. For homebuyers, this means potential hidden costs for water filtration, flood insurance, and home remediation.
