SITE INFORMATION

Site Description

The Gas Works Park site is approximately 42 acres located at 2101 North Northlake Way in Seattle, Washington. It includes about 21 acres of upland property and 21 acres of property within Lake Union. Most of the upland portion of the site is owned by the City and most of the in-water portion is owned by the State of Washington.

Contamination

Contamination at the site is mainly the result of historic gas manufacturing and tar refining operations. Contaminants include petroleum hydrocarbons, polycyclic aromatic hydrocarbons, volatile organic compounds, and arsenic.

Previous Cleanup Work

Under various legal agreements with Ecology over the years, PSE and the City have implemented multiple cleanup actions to address contamination in the upland portion of the site. These actions included soil removal, soil capping and groundwater treatment.

As a result, the in-water sediment portion of the site is the main area still requiring cleanup. Please click on the photo for a larger view
