Locate contaminated sites

We offer a variety of ways you can learn more about polluted properties we're cleaning up.

You can search an interactive map with our What's in My Neighborhood tool. If you know the site address or other cleanup site features, such as the site name or identification number, you can try the Cleanup Site Search. You can also use our Toxics Cleanup Web Reporting tool — a searchable database that provides a selection of reports and data sets (such as the Confirmed and Suspected Contaminated Sites list).

If you prefer statewide cleanup site information delivered to your email inbox, subscribe to receive the Site Register, a semi-monthly newsletter providing timely information on active cleanup sites and opportunities to weigh in on cleanup decisions.

Ecology also publishes a list of hazardous sites that have been ranked by their potential risk to people and the environment, in relation to other known contaminant sites. We update this list twice a year in February and August and distribute it to the Site Register email list. For more information about the Hazardous Sites List, please contact Jean Donaldson at 360-407-7106 or jean.donaldson@ecy.wa.gov.

What's in My Neighborhood?

We've made it easy to answer this question with our interactive mapping tool. You can search by your home or business address and find all the cleanup sites within a 0.25- to 10-mile radius, as long as they're in Washington.

The color of the dot marking a site identifies its' stage in the cleanup process. When you click a dot or the site name in the list that appears when you zoom into an area, you'll find more information about the selected cleanup site, including a link to the web page and documents about the site.

Cleanup Site Search

With this extensive database, you can search by:

  • Cleanup site name
  • County
  • Street address
  • City
  • Zip code
  • Cleanup or facility site identification number
  • Voluntary Cleanup Program project number

The web page that results is the same page you will be directed to when following a link from What's in My Neighborhood. The path getting there is the only difference.

Toxics Cleanup Web Reporting

This "portal" application provides a selection of reports and datasets. You can choose your own search criteria, then bring up either a nicely-formatted report (.pdf) or an Excel dataset. Datasets may be exported to other common formats such as Word, or text (.csv) file.

The reports draw data from our ISIS (Integrated Site Information System) and UST (Underground Storage Tank) data systems. We use the ISIS database to prioritize our work and track cleanup progress. The UST database holds information about regulated Underground Storage Tanks and facilities.

Available reports include:  The Confirmed & Suspected Contaminated Sites list, Environmental Covenants Registry, Leaking Underground Storage Tanks list, No Further Action Sites list, Voluntary Cleanup Program Wait List, lists of active and inactive regulated UST facilities, and more.

Site Register

The Site Register newsletter provides updates on cleanup activities. It focuses on sites about which we're gathering public feedback to inform our decisions.

You can find announcements about:

  • Public meetings
  • Public comment periods
  • Draft cleanup reports
  • Ecology's contact information for each site

Ecology publishes the Site Register every other Thursday. You can download back issues from our website.

Anyone can subscribe to receive the latest issue via email on a regular basis. You can join or leave the list at any time.

Hazardous Sites List

The Hazardous Sites List is a more extensive list of cleanup sites in Washington.

After a potentially contaminated site is reported to or discovered by Ecology, we investigate the site to assess the hazards it poses to people and the environment. After we assign a hazard ranking, the site is added to the list.

We update this list twice a year in February and August and distribute it via the Site Register email list. For more information about the Hazardous Sites List, please contact Jean Donaldson at 360-407-7106 or jean.donaldson@ecy.wa.gov.
