The Toxics Release Inventory (TRI) is a publicly available EPA database that contains information on toxic chemical releases and other waste management activities reported annually by certain covered industry groups as well as federal facilities. This inventory was established under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) and expanded by the Pollution Prevention Act of 1990.

Quick Links to Generate Reports from Data

Query the Envirofacts database and generate reports using online Query Forms. You may generate an integrated report by searching several EPA environmental databases using the Envirofacts (multisystem) Query form.

The Envirofacts Warehouse also allows you to search for more detailed information by querying the databases individually:  If you want to read a description of each of these databases first , just scroll down this page!

Envirofacts Multisystem

The Envirofacts Multisystem Query integrates information from a variety of databases and includes latitude and longitude information. Each of these databases contains information about facilities that are required to report activity to a state or federal system. Using this form, you can retrieve information about hazardous waste (including the Biennial Report), toxic and air releases, Superfund sites, and water discharge permits. This query is fully integrated with EnviroMapper. Go to Top Top



The federal government locates, investigates, and cleans up the worst hazardous waste sites throughout the United States. These sites are designated "Superfund sites." Common Superfund sites include abandoned warehouses, landfills, and industrial facilities that dumped hazardous waste into the environment before it was regulated. Use the Superfund Query form to retrieve information about designated Superfund sites. Go to Top Top



Permit Compliance System (PCS)
The Clean Water Act requires wastewater dischargers to have a permit that establishes pollution limits and specifies monitoring and reporting requirements. The National Pollutant Discharge Elimination System (NPDES) permits regulate household and industrial wastes that are collected in sewers and treated at municipal wastewater treatment plants. Permits also regulate industrial point sources and concentrated animal feeding operations that discharge into other wastewater collection systems or that discharge directly into receiving waters. The Water Discharge Permits query form allows you to retrieve permit information. The customized query engine allows you select any data element in PCS to build a tabular report or a Comma Separated Value (CSV) file for downloading. Go to Top Top

Safe Drinking Water Information
EPA collects data about how well water utilities comply with drinking water regulations and whether any enforcement actions were taken against utilities. This information is stored in the Safe Drinking and Water Information System database (SDWIS). Use the Safe Drinking Water Query form to view a utility's violations and enforcement history for the last ten years.Go to TopTop

National Drinking Water Contaminant Occurrence Information
In 1996, Congress mandated that a repository of drinking water occurrence information be created; this repository is the National Drinking Water Contaminant Occurrence Database (NCOD). The database holds information from a number of sources, including public water systems and source (ambient) water. NCOD contains regulated and unregulated contaminant data for public water systems. The NCOD Query Form allows you to access information on contaminant occurrence in an individual system or by geographical area.Go to TopTop

Drinking Water Microbial and Disinfection Byproduct Information
The Information Collection Rule (ICR) required water systems serving 100,000 people or more to collect samples and report on microbial (source water) and disinfection byproduct (treated water) levels for 18 months (July 1997-December 1998). Twelve months worth of these data is now stored in Envirofacts. Use the ICR Query Form to view reports at the water system, state, and national levels. Be sure to review the cautions on data use before interpreting the data.Go to TopTop


Hazardous Waste

Resource Conservation and Recovery Information System
The Resource, Conservation, and Recovery Act requires that generators, transporters, treaters, storers, and disposers of hazardous waste provide information concerning their activities to state environmental agencies. These agencies then provide the information to regional and national U.S. Environmental Protection Agency (EPA) offices. This information is available to you using the Hazardous Waste Data query form.Go to TopTop

Biennial Reporting System
Detailed hazardous waste information is collected on the generation of hazardous waste from large quantity generators and data on waste management practices from treatment, storage, and disposal facilities. This information is compiled into a Biennial Report and is useful for trend analysis.Go to TopTop



The Grants Information and Control System is used by Headquarters, regions, and states to track, award, administer, and monitor grants. Envirofacts provides the public with timely award information for most of EPA's Federal Grant Programs, specifically Construction, Non-Construction, and State Revolving Funds grant programs. The Grants Information query form allows you to read about projects that have received grants.Go to TopTop


Locational Information

Locational information for EPA-regulated facilities in Envirofacts is cultivated from many sources, including EPA federal program systems (through monthly snapshots), and EPA regional offices and the states (through Supplementary Return Files). This information is collected and refined under the auspices of the Locational Data Improvement Project (LDIP), which was enacted by the Agency to comply with the federal Locational Data Policies (LDP).

The locational information in Envirofacts is stored in the Locational Reference Tables (LRT). The LRT act as a storehouse for the actual locational data, as well as the business rules that are applied to them in order to provide the most accurate information available for depicting the locations of federally regulated entities. The EZ query allows you to select key data elements from EPA's Facility Information database and Locational Reference database to build a tabular report or a Comma Separated Value (CSV) file for downloading. Go to TopTop


Facility Information

The Facility Registry System in Envirofacts was derived from several sources, including all of the program systems in Envirofacts. Use the Facility Registry System query form or the Facility Registry System EZ Query to view facility data.Go to TopTop



The Environmental Radiation Ambient Monitoring System (ERAMS) is a national network of more than 200 monitoring stations distributed across all 50 states and the American Territories. Each station regularly samples the nation's air, precipitation, drinking water, or pasteurized milk for a variety of radionuclides (e.g., iodine-131) and radiation types (e.g., gross beta (b)). Use the Environmental Radiation Ambient Monitoring System query form or the Environmental Radiation Ambient Monitoring System Customized Query to view radiation data. The Radiation Information Database (RADINFO) Query allows you to retrieve selected data from RADINFO database in Envirofacts regarding facilities or sites that EPA regulates for radiation and radioactivity. Go to TopTop



Envirofacts contains information about stationary sources of air pollution (facilities) in the Aerometric Information Retrieval System (AIRS)/AIRS Facility Subsystem (AFS). Examples of facilities (sources) include electric power plants, steel mills, factories, and universities. Use the Air Releases query form to retrieve both emissions and compliance information for these facilities.

The UV Index query form predicts the next day's ultraviolet radiation levels for a particular city or ZIP code based on a 0-10+ scale. Go to TopTop



The Envirofacts Master Chemical Integrator query form allows you to obtain the acronyms, chemical identification numbers, and chemical names reported in Envirofacts. Chemical information is also available using the Air Release, Toxic Release, and Water Discharge Permits query forms.

Toxic Releases

The main purpose of the Toxics Release Inventory is to provide the public with information about potentially hazardous substances in their community. Currently 600 chemicals have been determined to be toxic, and certain industries must report to EPA if they use or handle these chemicals. This reported information is contained in Envirofacts. Toxic Releases query options include:
