The East Waterway Site (Site) is located in the Everett Harbor area near the mouth of the Snohomish River, directly west of downtown Everett. It is a deep-water port and industrial area with multiple sources of sediment contamination including historical discharges, as well as log rafting, which contributed to high levels of wood waste. The area was dredged and filled in the early 1900s to create the deep water port. The East Waterway channel is approximately 700 to 900 feet wide and 30 feet deep.
Primary uses of the waterway have included shipping and processing facilities for timber, pulp, alumina, deep water shipping operations by the Port of Everett, and naval activities. The Site has also been used to support petroleum operations, manufacture heavy equipment for the oil drilling industry and maintain naval shipyard operations. After merging with Scott Paper Company in 1995, Kimberly-Clark Worldwide, Inc. (K-C) became the owner of the pulp and paper mill. K-C operated the mill until 2012, when it filed for permits to demolish the facility to ready the property for sale and redevelopment.  Demolition began in summer 2012 and was completed by July 2013. In the 1970s, the Port of Everett (Port) developed part of the East Waterway into a cargo shipment facility. K-C, the Port and the Washington Department of Natural Resources (DNR) have been identified as Potentially Liable Persons (PLPs) at the Site.

Industrial and municipal activities have led to multiple sources of sediment contamination. Log rafting contributed to high levels of wood debris. Various environmental investigations at the Site conducted from the 1980s to early 2015 found marine sediments contaminated with: metals (arsenic, mercury, zinc, copper, lead), polycyclic aromatic hydrocarbons (PAHs), semivolatile organic compounds (SVOCs) including phenol, total polychlorinated biphenyls (PCBs) and dioxins/furans.


  • In December 2012, Ecology and K-C entered into an Agreed Order (AO) to clean up the upland area to the east of the Site. The East Waterway was not included in the upland area AO. To clean up remaining in-water contaminants, Ecology is entering into a separate AO with the PLPs – K-C, the Port and DNR – to research and identify hazardous substances at the East Waterway Site. This includes upland sources that could potentially release contaminants to the in-water area.  Any such contaminants identified will be addressed under a draft Remedial Investigation/Feasibility Study (RI/FS) and Draft Cleanup Action Plan (DCAP).
  • The draft AO is a legal document between Ecology and the PLPs which outlines the agreement to provide remedial action at the Site where there has been a release or threatened release of hazardous substances. The AO describes the studies the PLPs agree to perform on the Site and provides guidance on the draft RI/FS, DCAP and interim actions.
  • Both the RI/FS and DCAP are completed at a later stage of the cleanup process. The RI/FS will identify the types, locations and amounts of contaminants including upland sources that could potentially release contaminants to the in-water area.  It will also identify cleanup options for those contaminants. The DCAP will select the preferred cleanup option and explain how cleanup will be conducted. Interim actions may be completed during cleanup if required by Ecology.
  • Ecology and liable parties entered into a cleanup agreement in 2016 to address the contamination. The investigation work plan is being developed.
