Background Information |
Sample Map
Toxic substances are defined by the U.S.
Environmental Protection Agency (EPA) as those chemicals or mixtures that may present an
unreasonable risk of injury to human health or the environment. The Emergency
Planning and Community Right to Know Act gives the public the right to
know about toxic chemicals being released into the environment. This
law requires that facilities in certain industries, which manufacture,
process, or use significant amounts of toxic chemicals, report
annually on their releases of these chemicals. The reports contain information
about the types and amounts of toxic chemicals that are released
each year into the air, water, and land, as well as information on the
quantities of toxic chemicals sent to other facilities for further waste
management. The EPA decides which chemicals will be included in the reporting
process, determines the reporting thresholds for chemicals, and maintains
toxic release information in a database called the Toxics
Release Inventory (TRI). This map layer was produced by the EPA.
The EPA Envirofacts Data - Toxics Release Inventory map layer shows
locations of more than 49,000 toxics release sites in the United
States, Puerto Rico, and the U.S. Virgin Islands as of May, 2005.
Descriptive information includes the facility name and identification
number. More detailed information on toxic releases is available
from the EPA
Toxics Release Inventory Program page, and information on
TRI chemicals can be found on the TRI
Chemicals page. Definitions of
environmental terms can be found in the EPA
Terms of Environment.
