About Perfluorononanoic acid in the Toxic Release Inventory

The Toxic Release Inventory (TRI) tracks how much of each listed chemical U.S. industrial facilities release into the environment each year. EPA requires facilities in certain industry sectors that manufacture, process, or otherwise use TRI-listed chemicals above threshold amounts to report annually. In 2024, 7 facilities reported releasing perfluorononanoic acid to EPA's TRI program.

The primary release pathway is land disposal (203 lb), which includes landfills, surface impoundments, land treatment, and underground injection.

TRI data represents reported releases, not measured environmental concentrations. A facility reporting large releases of perfluorononanoic acid is not necessarily causing harm at those levels — toxicity, exposure pathways, and local conditions all matter. Conversely, small reported amounts of highly toxic chemicals can pose greater risk than large amounts of less toxic ones. TRI is a transparency tool, not a risk assessment.

For health information about specific chemicals, the Agency for Toxic Substances and Disease Registry (ATSDR) publishes toxicological profiles, and EPA's Integrated Risk Information System (IRIS) provides reference doses and cancer classifications.
