Introduction

This site contains information and resources on a variety of topics related to the growing field of ecological risk analysis. This is an updated and expanded version of the original ORNL site by this name. Whereas the previous version focused on ecological risk assessments for hazardous waste sites (i.e., chemicals), this site now contains information on the expanded role of ecological risk analysis in environmental decision making. All of the tools that made this site popular with risk assessors in the 1990s are still available. However, ORNL has been applying the principles and practices of ecological risk analysis to non-chemical stressors and to environmental management issues other than those typically associated with CERCLA remedial investigations, e.g., military training and testing activities. Information, tools, and other resources are provided for each of these areas below.

The information on this site is organized into the following topical areas:

  • Contaminated Sites and the associated ecological risks,
  • Petroleum-Contaminated Sites and the associated environmental risks,
  • Radionuclides and the associated ecological risks,
  • Net Environmental Benefit Analysis (NEBA),
  • Military Training and Testing activities and the associated environmental risks,
  • Air Pollutants and their environmental fate and effects,
  • Wastewater Treatment Risks for on-site treatment systems, and
  • Biological Uptake of chemicals by plants and animals.

These groupings reflect the broad array of environmental problems and issues to which ORNL has been applying the principles and practices of environmental risk analysis. This site also includes summary pages for all of the tools and links that are provided these groupings. These redundant pathways are intended to help facilitate user access to key technical information.

This site was prepared by the Environmental Sciences Division and Life Sciences Division of Oak Ridge National Laboratory for the U.S. Department of Energy. Partial support for this project was provided by the Strategic Environmental Research Development Program through DOE's Office of Environmental Policy and Assistance. We welcome your comments.
