- About CEC
CEC has performed risk assessments for numerous types of facilities across the country. Risk assessments have been a part of commercial and industrial real estate transactions (including brownfields sites), 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 values that are based on real world assumptions and remedial actions that are protective of human health and the environment while saving our clients millions of dollars. The overall objectives of CEC's approach to risk assessment include:
- definition and focus of site/operable unit issues through the use of tools such as screening criteria
- identification of realistic exposure scenarios in order to accurately characterize risks
- evaluation of solutions that consider the balance between environmental protection and cost
- understanding our clients needs and company structure in order to respond to financial, regulatory/legal, and day-to-day operational issues.
CEC has an experienced multi-disciplinary staff to address risk assessment issues. This staff includes individuals with Ph.D. and M.S. degrees and backgrounds in environmental science, toxicology, engineering, geology, hydrology, chemistry, computers, and statistics.
Human Health Risk Assessments
In accordance with federal guidance, most of CEC's human health risk assessments integrate the following four components: hazard identification - selection of the chemicals that can potentially cause an adverse effect; dose-response assessment -- description of the relationship between the chemical dose and anticipated response; exposure assessment -- identification of current and potential pathways to receptors (e.g., adult, child, worker); and risk characterization -- a comprehensive presentation of risk estimates and a thorough discussion of the uncertainties associated with these estimates.
Ecological Risk Assessments
An ecological risk assessment typically has three components: problem formulation -- establishing the goals and focus of the risk assessment, which includes the conceptual model that identifies the environmental values to be protected (assessment endpoints); analysis -- developing profiles of environmental exposure and the effects of the stressor; and risk characterization -- integrating the information from the first two components to provide an overall risk estimate and the confidence in the assessment.
