Appendix A, Section 9: Groundwater and Soil Quality — Study of the Current and Ongoing Effects of the Operation of the Seattle-Tacoma International Airport
This 2020 environmental study examines groundwater and soil quality at and around Seattle-Tacoma International Airport from 1997 to 2019, tracking changes in contamination levels and evaluating whether they stem from airport operations, other pollution sources, or stormwater runoff. The report draws on data from the Port of Seattle, surrounding cities, and state environmental agencies to assess the effectiveness of the airport's cleanup efforts and identify any contamination that may have spread beyond airport property. The underlying geology—dense glacial till soils—generally slows the movement of contaminants through the ground in the area. -
