EPA's Toxic Release Inventory Explorer

TRI explorer logo The TRI Explorer (more info) provides access to Toxics Release Inventory (TRI) data to help communities identify facilities and chemical disposal or other release patterns that warrant further study and analysis. TRI data reflect disposal or other releases and other waste management of chemicals, and not exposures of the public to those chemicals.
