Site details

The Western Port Angeles Harbor Sediment Cleanup Unit is approximately 1,160 acres located in the harbor from the downtown commercial/industrial area to Ediz Hook.

The remedial investigation shows that sediment contaminants in the western harbor include metals, dioxins/furans, polychlorinated biphenyls (PCBs), and carcinogenic polycyclic aromatic hydrocarbons (cPAHs).

People, pets, or wildlife that physically contact or accidentally eat contaminated sediment may be exposed to hazardous chemicals. People and wildlife may be exposed to contaminants when they eat contaminated fish and shellfish.

Cleanup options described in the feasibility study prevent these exposure pathways. Options for sediment cleanup include dredging, capping and containment, placing clean sand/gravel on top of contaminated sediments, and checking for natural deposition of cleaner material on top of contaminated sediments.


Past industrial operations generated liquid waste and released it directly into the harbor and lagoon. Contaminated stormwater was discharged into the harbor. Several pulp and lumber mills burned salt-laden wood debris as a fuel source. Burning this debris formed hazardous substances, like dioxins, that rose up through smoke stacks and settled out onto marine sediments.
