Health Risk Assessments
The environmental evaluation conducted in a risk assessment quantifies the effects of contaminants on human health or the environment. Health Risk Assessments provide guidelines as to whether remediation is necessary at a site, and if so, determine the appropriate clean-up goal. Health risk modeling allows for the development of site cleanup standards that will protect against chronic health or environmental impacts, namely, carcinogenic or toxic effects caused by long-term exposure to contaminants. Input included in the health risk evaluation includes source zone characteristics, exposure pathway information, and receptor information.
