How the live EPA-backed build works.
The site now serves a live national EPA-backed SQLite build. This page explains what is included today, what the source systems are, and what still needs deeper enrichment.
Sources
The three EPA layers in the brief
Superfund
Superfund
Cleanup status, contaminants, and milestone timelines for the most serious legacy contamination sites.
Mapped to site detail pages and county summaries.
TRI
TRI
Facility-level toxic release reporting across air, water, and land pathways, rolled into chemical and facility pages.
The clearest answer to 'what is being released near me?'
ECHO
ECHO
Inspection, enforcement, and significant noncompliance signals that make raw release tables more actionable.
The legal and due-diligence layer of the product.
Ingestion steps
The next production pass
Automate refresh and deploy so the national database can be updated on a schedule.
Add TRI years beyond 2024 so facility and county trend views have more historical depth.
Enrich Superfund pages with contaminants, remedy stages, and milestone history.
Improve ECHO and TRI facility joins where EPA identifiers diverge or roll up inconsistently.
Add monitoring, analytics, and editorial QA around refreshes so stale or broken pages are obvious.
What is already live
The live site surface is in place.
Homepage, states index, state, county, Superfund, facility, chemical, and violation pages are live.
Canonical paths follow the brief's SEO structure rather than a temporary scaffolding route scheme.
Search, sitemap, robots, metadata, schema, and address lookup are already part of the app surface.
