Cleaning Up: How you can track contaminated sites

By Seth Preston, Communications Manager, Toxics Cleanup Program

Ecology’s Toxics Cleanup Program offers two regular online products that can provide handy information on contaminated sites throughout the state.

Twice a year, we update the state’s Hazardous Sites List, which provides a county-by-county list of cleanup sites.

The most recent update is now online. You can find it and past versions of the Hazardous Site List on this webpage. The list usually is updated every February and August, though that can vary slightly.

The sites are ranked on a scale of 1 to 5 — sites with a 1 ranking are considered to pose the most risk of exposure to people and the environment.

We also offer the Site Register, which is published every two weeks. The Site Register provides information on specific sites that are progressing through the cleanup process. In it, you will find notices on public comment periods and other proposed actions.

You can find Site Register editions online here.
