Site Assessment & Remediation Process

Site Assessments are one component of the Remediation/Clean-Up process. A Site Assessment provides basic information for determining if there has been a release of hazardous material at a site, or if a naturally occurring hazardous material that presents a risk to human health or the environment may be present. A Site Assessment is conducted under the oversite of a regulatory agency to identify the type, amount and extent of contamination. The Remediation/Clean-Up process includes different components as displayed on the graphic. The final stage of the process is the clean-up phase which ensures that there are no risks to human health or the environment.
