To view a summary of TRI release data, choose from the two rows of options above the map or
search directly within the map by zooming in on a particular area and clicking on a state,
metropolitan area, or watershed. In addition to viewing maps based on release quantities, you
can also view maps based on risk-screening scores, which are estimates of potential human
health risk generated by EPA's Risk-Screening Environmental Indicators fRSEI) 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.

As with any dataset, there are several factors to consider when reading about or using the TRI
data. Key factors associated with data presented are summarized in the Introduction. For more
information see Factors to Consider When Using Toxics Release Inventory Data.
States and Metropolitan Areas
For TRI purposes, "states" includes all U.S. territories. For 2018, all 56 states and territories had
facilities that reported releases to the TRI Program. Texas, Ohio, and California had the most
facilities that reported to TRI, and together accounted for 20% of total TRI-reporting facilities in
2018.
More than 80% of the United States' population and many of the industrial and federal facilities
that report to the TRI Program are located in urban areas. "Metropolitan statistical areas" and
"micropolitan statistical areas" in the United States are defined by the Office of Management
and Budget (OMB) and consist of one or more socially and economically integrated adjacent
counties, cities, or towns.
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.
Water pollution, surface runoff, contaminated sediment, discharges of 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 tribes on a government-to-
government basis to protect the land, air, and water in Indian..countiy. 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 fBIAl tribal code on annual TRI reporting forms. These codes tell the EPA on
which tribal land the facility is located.
In 2018, there were 43 facilities located in the Indian country of 19 different federally
recognized tribes. These facilities collectively reported 41 million pounds of production-related
waste and 13 million pounds of releases (total disposal or other releases). Of the releases
reported, 99% of the TRI releases in Indian country occurred on site, and 94% of these
releases were disposal to land reported by electric utilities and metal mining facilities. In 2018,
these facilities primarily released metal compounds such as lead, copper and barium. Lead and
copper are often present in the mineral ore disposed of by metal mines, and barium is present
in coal and oil combusted 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.
