Risk Assessment

Risk Tools and Databases

EPA has developed help for assessing and managing environmental risks, including guidance and tools which are the models and databases used in risk assessments. In some cases, these resources are broad enough to be relevant across all statutes that EPA administers while in other cases, they are more applicable to specific EPA programs.

Below are links to various risk assessment resources used by EPA scientists to assess risks to environmental hazards listed by:
