The TCEQ defines an ecological risk assessment as a process that evaluates the likelihood that adverse ecological effects are occurring or may occur as a result of exposure to one or more chemicals of concern (COCs) from a remediation site. In general, the primary functions of an ecological risk assessment are as follows: The definitive reference in its field, Ecological Risk Assessment, Second Edition details the latest advances in science and practice. USEPA uses ecological risk assessments to evaluate the likelihood that adverse ecological effects are occurring or may occur as a result of exposure to one or more chemical or physical stressors. EPA uses risk assessment to characterize the nature and magnitude of health risks to humans and ecological receptors from chemical contaminants and other stressors that may be present in the environment. Ecological Risk Assessment is a structured scientific evaluation of the potential for harm to occur to ecological receptors as a result of exposure to some stressor, often an exposure to chemical contamination. In the fourteen years since the publication of the best-selling first edition, ecological risk assessment (ERA) has moved from the margins into the spotlight.

Section 7 - Ecological Risk Assessment The ecological RA will be conducted for CSSA using the most current protocols and toxicity information available at the time of the assessments. Ecological risk assessment (ERA) has matured since the 1970s when it began as ecological assessment. This online program provides attendees with a comprehensive overview of regulatory expectations of ecological risk assessments from both federal and state perspectives. Ecological Risk Assessment (EcoRA) involves the assessment of the risks posed by the presence of substances released to the environment by man, in theory, on all living organisms in the variety of ecosystems which make up the environment. An Ecological Risk Assessment (ERA) evaluates the likelihood that adverse ecological effects are occurring or may occur as the result of exposure to one or more stressors.
