REVA STRESSOR ATLAS
Citation:
REVA STRESSOR ATLAS. U.S. Environmental Protection Agency, Washington, D.C., 2002.
Impact/Purpose:
The Stressor Atlas represents the first product of EPA's Regional Vulnerability Assessment (ReVA) program. The aim of ReVA is to develop and test advanced scientific methods tools to conduct value-based ecological risk assessments to support community-based environmental protection efforts. The program provides predictive tools to inform regional decision-makers as to where future environmental problems are likely to occur and to illustrate the trade-offs associated with alternative environmental and economic policies. This applied research is being coordinated by EPA's National Exposure Research Laboratory and builds on collaborations throughout EPA's Office of Research and Development and with other partners both inside and outside of EPA.
ReVA relies heavily on the use of Geographic Information Systems (GIS) technology to develop overlays of geospatial patterns of stressors, receptors, and ambient conditions that modify exposures or effects to identify areas where exposures are likely to represent in the greatest risks to one or more receptors. The resulting overlays are called "profiles" (e.g., stressor profiles, receptor profiles, and the resulting exposure profiles). The Stressor Atlas represents a first step towards integrating information into a regional-scale comparative risk assessment that aims to allow targeting of limited resources towards environmental problems that are likely to emerge in the next 5 to 25 years. The Stressor Atlas document is available for download through the ReVA website (http://www.epa.gov/nerlesd1/land-sci/ReVA/StressorAtlas/sa1.pdf)
