Update on the Lora Lake Apartments Cleanup Site: Highline Forum Meeting Presentation

A 2012 presentation to the Highline Forum provides an update on the Lora Lake Apartments cleanup site near Sea-Tac Airport, where dioxin contamination is being addressed through a combination of excavation and capping. The Port of Seattle submitted a draft Remedial Investigation/Feasibility Study to the Washington State Department of Ecology, which was reviewing the document and planning to issue it for public comment before selecting a final cleanup action. The site was not found to be contributing significant amounts of dioxin to the nearby Miller Creek.
