To view a summary of TRI release quantity 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 (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.

As with any dataset, there are several factors to consider when 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.

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