About this data

EPA publishes contamination data through three separate tools that don't talk to each other. PollutionLookup.com unifies them so you can answer one question — what's near me? — without three browser tabs.

Superfund NPL — National Priorities List of America's worst contaminated sites with active or pending federal cleanup. ~1,400 sites.
Toxic Release Inventory (TRI) — Annual self-reported chemical releases from manufacturing and mining facilities. ~23,000 active reporters across ~600 chemicals.
ECHO — EPA's enforcement and compliance database. Facilities regulated under the Clean Air Act, Clean Water Act, and RCRA, with inspection history and penalty totals.
