This December 2001 report, prepared by Hart Crowser, Inc. for the Port of Seattle, presents baseline chemical characterization results for the Black River Quarry in Renton, Washington, which was evaluated as an off-site borrow source of fill material for the Sea-Tac Third Runway Project. The study involved soil sampling, metals analysis, and data quality review to assess the suitability of quarry material for use in runway construction. Tables and figures detail sample locations, soil descriptions, and total metals analytical results from laboratory testing by North Creek Analytical, Inc.

In December 2001, Ann Kenny of the Washington Department of Ecology's Northwest Regional Office drafted a memo requesting that hydrogeologist Ching-Pi Wang review a groundwater and seepage monitoring plan submitted by the Port of Seattle for the proposed third runway at Seattle-Tacoma International Airport. The plan, titled 'Third Runway Embankment Seepage and Groundwater Monitoring Plan,' was submitted on November 16, 2001, and required expert review before Ecology could approve it. Wang was asked to provide written comments on the plan's adequacy and any recommended changes by January 18, 2002.

This December 2001 report, prepared by Parametrix, Inc. and several partner firms for the Port of Seattle, analyzes low streamflow conditions and proposes a Summer Low Flow Impact Offset Facility as part of the Seattle-Tacoma International Airport Master Plan Update Improvements. The study examines how planned airport expansion may affect seasonal low-flow water resources in the surrounding area and outlines mitigation measures to offset those impacts. The report is organized across multiple volumes, with Volume 1 containing the main text and Appendices B through J.

This technical document compares observed and model-predicted 7-day low streamflows for Walker Creek and Des Moines Creek near Seattle-Tacoma Airport for water years 1991–1996. Results show that calibrated (simulated) flows generally underestimated observed flows at most gage locations, with the exception of 1995, when the model overpredicted flows. Discrepancies at upstream gage locations are attributed to uncertain groundwater conditions within the watersheds.
