Toxics Release Inventory (TRI) Program

TRI Data and Tools

The Toxics Release Inventory (TRI) Program tracks the management of toxic chemicals that may pose a threat to human health and the environment. Facilities in certain industry sectors report annually the volume of toxic chemicals managed as waste--recycled, treated or burned for energy recovery--as well as disposed of or otherwise released into the environment.

Use TRI data in conjunction with other EPA data sources for comparative analysis.

  • TOXMAP: Explore environmental health data related to Superfund sites and TRI-reporting facilities using GIS-based maps developed by the National Library of Medicine.
  • DMR (Discharge Monitoring Report) and TRI Comparison Dashboard: Compare DMR and TRI release data. Determine what pollutants are being discharged into waterways, and by which companies.
  • Enforcement and Compliance History Online (ECHO): Search EPA and state compliance and enforcement records for air, water, and hazardous waste regulations, including contextual data for TRI and other programs.
  • Enviromapper: Generate maps that contain environmental information, including TRI information. Add features such as schools, streets, and water bodies to view the information in context.
  • TRI-CHIP (TRI Chemical Hazard Information Profiles): Access and analyze toxicity information from multiple data sources for chemicals included on the TRI list.
  • TRI metadata: Get reference information to support use and understanding of TRI data. Includes lists of chemical categories, associated health effects, covered industry codes, and codes used on reporting forms.
