TRI National Analysis

What's in the 2017 TRI National Analysis

The Toxics Release Inventory (TRI) National Analysis is prepared and published annually, and the 2017 TRI National Analysis is EPA's summary and interpretation of TRI data reported for activities that occurred at facilities in the U.S. during 2017. It offers valuable information for improving our understanding of how the environment and communities may be affected by TRI chemicals and is a snapshot of the data at one point in time. To conduct your own analysis of TRI data, use the most recent data available on the TRI Data and Tools webpage.

Additional information is presented in the following sections of the TRI National Analysis:

  • Pollution Prevention and Waste Management presents the types of pollution prevention activities that facilities have implemented, and trends on recycling, energy recovery, treatment, and releases of TRI chemical waste generated and managed as part of industrial operations.
  • Releases of Chemicals presents trends in releases of TRI chemicals to the air and water, and disposed of to land, including a focus on selected chemicals of special concern.
  • Industry Sectors highlights TRI chemical waste management trends for five industry sectors: manufacturing, paint and coating manufacturing, chemical manufacturing, metal mining, and electric utilities.
  • Where You Live presents analyses of the TRI data specific to U.S. geographic areas: state, city, county, ZIP code, metropolitan area and micropolitan area, and by Large Aquatic Ecosystems (LAEs), such as the Chesapeake Bay, as well as information about facilities in Indian Country.
  • TRI and Beyond presents TRI data used in conjunction with data from other environmental programs, such as chemical production data reported to EPA under the Toxic Substances Control Act (TSCA). The use of TRI as a model for other pollutant release and transfer inventories around the world is also discussed in this section.

This page was published in March 2019 and uses the 2017 TRI National Analysis dataset made public in TRI Explorer in October 2018.
