2023 TRI Community Profile -

The Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. U.S. facilities in different industry sectors that meet reporting requirements must report annually how much of each chemical is released into the environment and/or managed through recycling, energy recovery, and treatment. For more information about the TRI data in this profile, visit the TRI Toxics Tracker tool.

You can use TRI and Risk-Screening Environmental Indicators (RSEI) data to start a conversation about facilities in your community and potential sources of exposure to toxic chemicals.

Map of TRI Facilities in in 2023

Each dot on the map represents a single facility and is sized and color coded based on the total release quantity reported in 2023.

Total Releases: Total on- and off-site releases of chemicals emitted into the air or water, placed in some type of land disposal, or transferred off site to another location for disposal or release.

P2 Activities: Activities that eliminate or reduce the use of TRI-listed chemicals and the creation of chemical waste.

Average 3-Mile Population: The average number of people living within 3 miles of each TRI facility, based on U.S. Census data.

Trends in Releases and RSEI Hazard

Looking at release data over time can provide a better sense of potential human exposure to toxic chemicals. The RSEI screening tool provides context for a subset of TRI emissions data. One result is the RSEI Hazard, which is a calculated number that expresses relative potential harm of TRI chemicals based on the quantities and toxicities of chemicals.

Summary of Releases



Looking at TRI releases by environmental media helps to understand where chemicals are emitted. Releases into the air and water are often more concerning because people may be exposed to the chemicals as they disperse in the air, interact with other chemicals, dissolve in water, or bioaccumulate in organisms.

Types of Releases
  • Air includes fugitive air releases (non-point sources such as leaks) and stack air releases (point sources such as a smokestack).
  • Water includes discharges to bodies of water, such as streams and rivers, or runoff.
  • Land includes several types of disposal, such as placement of waste in landfills, in surface impoundments, and underground injection wells.
  • Off-site releases includes waste transfers to facilities geographically or physically separate from the TRI reporting facility. Most quantities are disposed of to land but some are released into the environment.

Top Facilities in by Releases in 2023

Facilities are ranked in descending order by releases in 2023. Facilities with zero releases reported are not included.

Summary of RSEI Hazard

RSEI Hazard values are calculated for chemicals, facilities, and geographic locations and are intended to be compared to other similar RSEI Hazard values. Comparing these results can help you identify the relative potential harm following releases of the same or different toxic chemicals in a given area. For example, the higher the RSEI Hazard in a specific geographic location compared to another, the greater the relative potential for harm. The charts below provide information for understanding relative potential harm.

Industry Profile and Additional Resources

Industry Profile Summary

The bar charts below summarize the top chemicals for up to five industries present in the community. Looking at TRI information by industry provides insight into the industrial activity informing targeted next steps.

Next Steps and Additional Resources

While TRI and RSEI data can provide important information about chemical releases in communities, for a more comprehensive understanding of potential impacts from facilities, we need to review additional information. A next step could be to identify pollution prevention actions that could be implemented by industry. See links to additional resources.
