Everett Smelter cleanup

Ecology is cleaning up lead and arsenic contamination left behind by the Everett Smelter, in residential and industrial areas of Northeast Everett.

The Everett Smelter was operated by Asarco from 1894–1912, but the contamination wasn't discovered until 1990. Smelter operations left high levels of arsenic and lead on the former smelter property. Contaminated particles from the smokestacks settled over a 1.1 square mile area.

We're more than halfway done

We've completed cleanup work on more than half of the approximately 700 homes in the uplands area and at American Legion Memorial Park. We have sampled for contamination at all the properties that requested it. For details, see our cleanup progress page.
The cleanup site is divided into Uplands (residential) and Lowlands cleanup areas. The two areas are on different cleanup schedules.

From 1999–2007, we managed cleanup of the most highly contaminated areas, including the former smelter property.

In 2009, we received funding through a bankruptcy settlement with Asarco to continue cleanup work.

We have now spent most of the settlement funds on residential cleanups in the uplands area and development of a cleanup plan for the lowlands area. We are seeking additional state funds to continue cleanup.

With the remaining settlement funds, we will complete prioritized phases of lowlands area cleanup.
