2012 TRI Factsheet: Large Aquatic Ecosystems - Chesapeake Bay
Data Source: 2015 National Analysis dataset (released October 2016) (updated November 29, 2016)
The Toxics Release Inventory (TRI) tracks the management of certain toxic chemicals that may pose a threat to human health and the environment. Certain industrial facilities in the U.S. must report annually how much of each chemical is recycled, combusted for energy recovery, treated for destruction, and disposed of or otherwise released on- and off-site. This information is collectively referred to as production-related waste managed.
|Chesapeake Bay ranks 4 out of 10 large aquatic ecosystems in the country based on total releases per square mile (Rank 1 = highest releases)|
Looking at production-related waste managed over time helps track progress in reducing waste generated and moving toward safer waste management methods. EPA encourages facilities to first eliminate waste at its source (source reduction). For waste that is generated, the preferred management method is recycling, followed by energy recovery, treatment, and as a last resort, disposing of or otherwise releasing the waste. Under the Pollution Prevention Act of 1990, TRI collects information to track industry progress in reducing waste generation and moving towards safer waste management alternatives.

The following charts represent releases of TRI-covered chemicals to the environment in the LAE of Chesapeake Bay. A "release" of a chemical means that it is emitted to the air or water, placed in some type of land disposal, or transferred off-site for disposal or release.
