Site Assessment

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.

The Superfund site assessment process is used to evaluate potential or confirmed releases of hazardous substances that may pose a threat to human health or the environment. The process is guided by criteria established under the Hazard Ranking System (HRS) and is carried out by EPA, State, Tribal, or other Federal Agency environmental programs. Following notification of a potential site, a series of assessments are carried out until a final decision is reached regarding the need for remedial cleanup attention. Several cleanup approaches are available. The following diagram illustrates the major components of the site assessment process.
