Allegheny County Toxics Release Inventory

The Toxics Release Inventory (TRI) data provides information about toxic substances released into the environment or managed through recycling, energy recovery, and treatment in the United States. Annual releases are compiled and reported by the U.S. Environmental Protection Agency (EPA) and shared on the TRI Website. The TRI covers over 650 chemicals and chemical groupings across a broad range of industries. Chemicals covered are linked to cancer or other chronic human health effects, tied to significant adverse human health effects, or significant adverse environmental effects.

NOTE: In 2024 the EPA's API underwent a back-end migration, and the tables used to feed the TRI tables below are currently broken, however users can still query the EPA's website for this information by using the links to each table listed as an HTML resource below and supplying the State FIPS Code of "42003" to limit the return to only Allegheny County on the Search Criteria page.
