Environmental Cleanup Site Information Database   

DEQ maintains its Environmental Cleanup Site Information database to track sites in Oregon with known or potential contamination from hazardous substances, and to document sites where DEQ has determined that no further action is required. Data in ECSI is "working information" used by DEQ's Environmental Cleanup Section. Please note that:

  • Some information in ECSI may be unconfirmed, outdated, or incomplete.
  • Data in ECSI is summary in nature, rather than comprehensive.
  • There may be contaminated sites in Oregon that are unknown to DEQ and do not appear in ECSI. Conversely, the appearance of a site in ECSI does not necessarily mean that the site is contaminated.
  • Information in ECSI is subject to change at any time.

If you are unfamiliar with ECSI, or need more information about its contents and limitations, DEQ recommends that you review the brief ECSI frequently asked questions web page before using this query.
