Goodwill Corp Dearborn Campus

Updated January 2022

Cleanup plans for the Goodwill Corp Dearborn Campus cleanup site (site) are in development. Remedial investigation activities are underway. Assistance for this cleanup will come from Ecology’s affordable housing grant program. 

The site is located off Dearborn St in the Central District neighborhood of Seattle, WA. It consists of 11 King County tax parcels totaling approximately 10.25 acres.  The Site is currently developed with paved parking or storage areas and four commercial buildings in use as a Goodwill retail store, two storage buildings in use by Goodwill, and the Goodwill Learning Center. Over the years, various businesses occupied the site, such as auto painting shop, plating works companies, refrigerator machinery and repair, service station and auto body and repair shop. 

The site is divided into seven blocks, labeled A - G (see figure). 

Contamination 

Prior investigations have identified contaminants in soil and groundwater, likely associated with historical releases from:

• A former on-site dry cleaner (Block E)

• A hazardous materials storage area (Block F)

• Former petroleum underground storage tanks (USTs; Blocks A, D, and C)

• A former metal plating operation (Block C)

• Use/storage of Stoddard solvent (Blocks A and E)

• Placement of contaminated urban fill material across most of the site

The Model Toxics Control Act (MTCA; Chapter 70.105D RCW is Washington’s environmental cleanup law). It provides requirements for contaminated site cleanup and sets standards that protect human health and the environment. Ecology enacts the MTCA and oversees cleanups. The MTCA site cleanup process is completed in steps (see graphic below) over a variable timeline.
