How we compute this

We sum the annual on-site and off-site release quantities that industrial facilities report to the EPA Toxics Release Inventory (TRI) and present the national total. The figure recomputes when EPA publishes a new reporting year.

A reported release is a disclosed quantity under federal right-to-know rules, not a measure of exposure or health outcome at any address. Release totals span hundreds of regulated chemicals with very different properties.

We translate EPA’s reported quantities rather than estimate them. Facility self-reporting is the basis of the inventory, as the program is designed.
