Ecological Risk Assessment

CEC has performed risk assessments for numerous types of facilities across the country to support the identification of real human health and environmental risks and the selection of remedial actions, if appropriate. Risk assessments have been a part of projects involving commercial and industrial real estate transactions, industrial operations, waste processing and disposal facilities, above and underground storage tanks, and CERCLA and RCRA sites.

CEC's involvement with the risk assessment aspects of projects has resulted in cleanup standards that are based on "real world" assumptions and remedial actions that are protective of human health and the environment, while saving clients millions of dollars. The overall approach to risk assessment frequently includes:

In accordance with Federal guidance, most of the human health risk assessments integrate the following four components:

In contrast ecological risk assessments typically have three components:

The approach to ecological risk assessment differs from that applied to humans because

  1. The effects typically go beyond one species (e.g., humans) and may consider population, community, or ecosystem impacts
  2. The stressors can be both physical (e.g., habitat modification) and chemical in nature
  3. The process requires selection of practical measurement endpoints (e.g., mortality of fish) that can reasonably be measured within finite time and budget constraints and yet relate to the selected assessment endpoint (e.g., decline of a fish population)
