In February 2001, engineering firm GeoSyntec Consultants submitted a technical review letter on behalf of the Airport Communities Coalition, raising serious concerns about the proposed Third Runway expansion at Seattle-Tacoma International Airport. The review identified significant deficiencies in the geotechnical investigation and analysis supporting construction of the embankment fill and West MSE Wall, including insufficient soil strength data and inadequate seismic safety assessments. GeoSyntec warned that the proposed design — which would result in the world's tallest MSE wall built over weak, potentially unstable soils in a seismically active region — could fail under earthquake conditions, threatening both airport operations and nearby natural resources.

This March 2000 report, prepared by Washington State health and environmental agencies, addresses community health concerns about air quality around Seattle-Tacoma (Sea-Tac) Airport by examining whether jet engine exhaust emissions can be monitored or modeled using wind and takeoff data. It outlines recommendations for conducting a comprehensive air quality study, including monitoring methods, data analysis approaches, and estimated costs, while also considering health impacts and environmental justice issues for nearby residents. The report was developed in consultation with public health officials, community representatives, the EPA, and local universities.

This December 1999 report from the Washington State Department of Health investigates community health concerns near Seattle-Tacoma (SeaTac) International Airport, focusing on whether cancer rates—particularly glioblastoma and breast cancer—are elevated in surrounding neighborhoods. The report examines potential links between jet engine exhaust emissions and health outcomes, reviews air quality studies, and assesses respiratory disease risks, especially for schools located under flight paths.
