Ecological Risk Assessment
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. DEEP is currently developing guidance for conducting Ecological Risk Assessments within the remediation-based programs at DEEP. While this guidance is under development, the following documents and links may be useful to those interested in evaluating ecological risks within Connecticut.
The following references provide useful information regarding ecological risk assessments:
Connecticut Water Quality Standards
Connecticut Remediation Standard Regulations
