A study at Seattle-Tacoma International Airport found that galvanized metal roofing on cargo buildings was the primary source of elevated zinc levels in the airport's stormwater runoff, which drains into salmon-bearing streams including Miller Creek and Des Moines Creek. Researchers used whole effluent toxicity (WET) testing and source-tracing methods to identify the problem, focusing on one outfall (SDN1) that consistently showed higher zinc concentrations and toxic effects on aquatic organisms. The findings prompted the Port of Seattle to investigate remediation options as part of its stormwater pollution prevention program under its NPDES permit.

In this 2001 declaration filed before Washington State's Pollution Control Hearings Board, Dr. Peter Willing challenges the Port of Seattle's commitment to improving stormwater management at Sea-Tac Airport. He argues that the Port's pledge to retrofit its stormwater system 'to the extent practicable' is vague, undefined, and falls short of required water quality standards. Dr. Willing also contends that the four best management practices listed in the Port's Stormwater Master Plan are largely inadequate, as most do not go beyond basic King County water quality requirements.
