Title: TRI National Analysis: Mapping Data for the Toxics Release Inventory Releases at Various Summary Geographic Levels
Abstract: These data provide mapping, display, and analysis capabilities for the TRI National Analysis data at the following geographic levels: state, county, large aquatic ecosystem, metro/micropolitan statistical area, and facility. See the links below for data from specific reporting years. The TRI National Analysis is EPA's annual interpretation and summary of the most recent TRI data. It highlights how toxic chemical wastes were managed, where toxic chemicals were released and in what quantities, and how the TRI data compare to data from previous years. This dataset reports US, state, county, large aquatic ecosystem, metro/micropolitan statistical area, and facility level statistics of TRI releases, including information on: number of TRI facilities in the geographic area and their releases (total releases, as well as releases to water, air, and land); population information, including populations living within 1 mile of TRI facilities (total population, percent minority, and in percent under the poverty line); and Risk Screening Environmental Indicators (RSEI) model related pounds, toxicity-weighted pounds, and RSEI score. The source of administrative boundary data is the 2013 cartographic boundary shapefiles. Location of facilities is provided by EPA's Facility Registry Service (FRS). Large Aquatic Ecosystems boundaries were derived from the hydrologic unit boundaries and codes for the United States, Puerto Rico, and the U.S. Virgin Islands. It was revised for inclusion in the National Atlas of the United States of America (November 2002), and updated to match the streams file created by the USGS National Mapping Division (NMD) for the National Atlas of the United States of America.
Purpose: To provide mapping, display, and analysis capabilities for the TRI National Analysis data at the following geographic levels: state, county, large aquatic ecosystem, metro/micropolitan statistical area, and facility. See the links below for data from specific reporting years.
