TOXMAP is a web site that uses maps of the United States to show the amount and location of toxic chemicals released into the environment. Data is derived from the Environmental Protection Agency's Toxics Release Inventory (TRI) (http://www.epa.gov/tri/), which provides information on the releases of toxic chemicals into the environment as reported annually by industrial facilities around the United States. TOXMAP helps users create nationwide or local area maps showing where chemicals are released into the air, water, and ground. It also identifies the releasing facilities, color-codes release amounts for a single year, and provides multi-year chemical release trends, starting with 1987. Users can search the system by chemical name, chemical name fragment, and/or location (such as city, state, or zip code).
