Project Library Archive

This page may be viewed in: English

This Project Library (Archive) includes final, EPA-approved documents. There are many reports, planning documents, maps, and other documents available that relate to cleanup efforts on the Lower Duwamish Waterway (LDW) as part of the Superfund process. Links to other websites dedicated to the waterway can be found in the Other Duwamish River Resources section. Unless otherwise noted, these documents are PDFs.

Documents in the Project Library Archive are maintained for reference, research, or recordkeeping purposes. Archived documents created before April 26, 2027 are retained in the archive for those purposes, and are generally maintained in their original form without substantive modification (e.g., by altering, adding, updating, or rearranging content). Modifications that are minor adjustments to web content, such as redacting personally identifiable information, are allowed.

Because archived materials are retained in their original form, some documents may not be fully accessible. Documents added on or after April 26, 2027, are intended to meet applicable accessibility requirements under Title II of the Americans with Disabilities Act (ADA). Read more about the rule in this ADA.gov Factsheet.

If you need assistance accessing archived materials or would like to request information in an accessible format, please contact info@ldwg.org or 1-888-561-5394.
