About the Data
Data sourced from the EPA Toxic Release Inventory (TRI) program. Facilities in covered industry sectors that manufacture, process, or use listed chemicals above threshold quantities must report annually. The map uses the most recent available EPA TRI dataset. Release volumes reflect regulatory reporting quantities and are not direct measures of health hazard or human exposure. For the full national picture and all-state rankings, visit the US Toxic Release Inventory Map.
