This section of the National Analysis looks at releases and other disposals of TRI chemicals that occurred at various geographic levels throughout the United States.

To view a summary of Toxics Release Inventory (TRI) data, select search parameters within the top two rows or query the map directly. In addition to viewing the maps based on releases, you can also view the maps based on "RSEI risk-screening scores." RSEI risk-screening scores are estimates of potential human health risk generated by EPA's Risk-Screening Environmental Indicators (RSEI) model. These unitless scores represent relative human health risk from chronic exposures to TRI chemicals and allow one to compare RSEI scores across locations. For more on RSEI, see the Hazard and Potential Risk of TRI Chemicals section.

  • States

    States include all U.S. territories for a total of 56 states/territories. All states have facilities that reported releases to the TRI Program for the 2016 reporting year. The states with the greatest number of facilities that reported are Texas, Ohio and California, which together accounted for 20% of total reporting facilities in 2016. Selecting a state on the map will provide a pop-up with:

    • a state level summary of TRI data
    • a link to the state level TRI fact sheet
    • an option to zoom to the counties within the state.
  • Metropolitan Areas

    More than 80% of the United States’ population and many of the industrial facilities that report to the TRI Program are located in urban areas. This map option shows all metropolitan and micropolitan statistical areas (metro and micro areas) in the United States as defined by the Office of Management and Budget (OMB) within which TRI-reported releases occurred in 2016. Metro and micro areas consist of one or more socially and economically integrated adjacent counties, cities, or towns. Click on any of these areas on the map for an analysis of TRI data specific to each.

  • Watersheds

    A watershed is the land area that drains to a common waterway. Rivers, lakes, estuaries, wetlands, streams, and oceans are catch basins for the land adjacent to them. Ground water aquifers are replenished based on water flowing down through the land area above them.

    Large aquatic ecosystems (LAEs) comprise multiple small watersheds and water resources within a large geographic area. The Large Aquatic Ecosystems Council was created by the U.S. Environmental Protection Agency in 2008 to focus on protecting and restoring the health of critical aquatic ecosystems. Currently, there are 10 LAEs in this program. Click on any of the 10 LAEs featured on the map to see an analysis of toxic chemical releases in each LAE.

    Water pollution, surface runoff, contaminated sediment, discharges of toxic chemicals, and air emissions can affect the quality of the land, water, and living resources within an aquatic ecosystem. Persistent, bioaccumulative and toxic chemicals can be especially problematic in aquatic ecosystems because pollutants can accumulate in sediments and may bioaccumulate in aquatic organisms and the tissues of fish and other wildlife within the food chain to concentrations many times higher than in the water or air, which ultimately may cause environmental health problems for humans and wildlife.

  • Tribal Communities

    Under EPA policy, the Agency works with federally recognized tribesHelptribe"Tribe" means an Indian or Alaska Native tribe, band, nation, pueblo, village or community that the Secretary of the Interior acknowledges to exist as an Indian tribe pursuant to the Federally Recognized Indian Tribe List Act of 1994, 25 U.S.C. 479a. on a government-to-government basis to protect the land, air, and water in Indian countryHelpIndian countryIndian country as defined in 18 U.S.C. 1151. That section defines Indian country as:(a) All land within the limits of any Indian reservation under the jurisdiction of the United States government, notwithstanding the issuance of any patent, and including rights-of-way running through the reservation;(b) All dependent Indian communities within the borders of the United States whether within the original or subsequently acquired territory thereof, and whether within or without the limits of a State; and (c) All Indian allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same. [40 CFR § 372.3] and Alaska Native villages and to support tribal assumption of program authority. Facilities located in Indian country that meet TRI reporting requirements must indicate the appropriate three-digit Bureau of Indian Affairs (BIA) tribal code on annual TRI reporting forms.

    In 2016, there were 40 facilities located in the Indian country of 16 different federally recognized tribes. These facilities reported a total of 25 million pounds of production-related waste and 9 million pounds of releases (total disposal or other releases). Over 99% of the TRI releases in Indian country occurred on site at facilities. 94% of these releases were land releases reported by electric utilities and metal mining facilities. In 2016, these facilities primarily released metal compounds such as lead and barium. Lead is often present in the mineral ore disposed of by metal mines, whereas barium is present in coal and oil burned at electric utilities.

    The table below provides more details about various types of releases and waste management reported by facilities on federally recognized tribal lands.

    The interactive chart below lists the federally recognized tribes with at least one TRI facility reporting 2016 data on their land, and includes various data related to TRI releases by facilities located on tribal lands. Use the buttons in the top gray row to filter the data by industry sector, chemical, and/or tribe. The blue dropdown button on the left allows you to view the data differently by changing which chart is displayed. Visit the TRI for Tribal Communities Qlik dashboard to explore even more information about releases of chemicals on or near tribal lands. Additional information about all TRI facilities is also available in the full 2016 TRI National Analysis Qlik dashboard.

    The interactive table below lists the federally recognized tribes that had at least one facility on their land that reported TRI data for 2016, along with the total releases reported by facilities, the number of facilities, and a link to a fact sheet with more information about TRI facilities on each tribe’s land. Click on a column header to change the sorting of the table.
