A variety of documents are written during the cleanup and assessment of sites addressed under the Superfund program. The online collection of Site Documents ranges from preliminary assessments, written during the early stages of reviewing a site for contamination, to Five-Year Reviews, written after the remedial action (treatment) is implemented. Many of the documents can be searched on keyword (such as a contaminant or remediation type), or other criteria.

Additionally, you can request copies of documents from the EPA Superfund Docket: Email:
