Toxics Release Inventory (TRI) Program

TRI for Communities

The Toxics Release Inventory (TRI) provides information for communities to learn about toxic chemicals that industrial facilities are using and releasing into the environment, and whether those facilities are doing anything to prevent pollution.

Video: Using Data for Collaborative Action in Communities

A Minneapolis community group used TRI data to start a partnership with a local company that resulted in decreased air emissions.

Is it safe to live near TRI facilities?

The human health risks resulting from exposure to chemicals are determined by many factors. TRI contains some of this information, including what chemicals are released from industrial facilities; the amount of each chemical released; and the amounts released to air, water, and land. Although TRI can’t tell you whether or to what extent you’ve been exposed to toxic chemicals, it can be used as a starting point in evaluating potential risks to the health of your community and the environment.

Learn more about TRI and estimating potential risk and EPA's Risk-Screening Environmental Indicators (RSEI) model.

What can I do?

You can use TRI data to start a conversation about your community's environmental health concerns with local groups, government officials, facility representatives, and others. Learn more about what you can do with the TRI data you find.
