Direct testimony of Kevin Fitzpatrick, Section Manager of the Northwest Regional Office Water Quality Section, Washington State Department of Ecology, submitted before the Pollution Control Hearings Board (PCHB) in case No. 01-160. Airport Communities Coalition (ACC) and Citizens Against Sea-Tac Expansion (CASE) are appellants; State of Washington Department of Ecology and Port Of Seattle are

This document outlines the Port of Seattle's soil fill quality criteria for the first phase of construction of a new runway embankment, involving approximately 820,000 cubic yards of material placed in 1998. It details the approved sources for fill material, technical specifications for soil gradation and contamination standards, and the certification and monitoring processes required of contractors. Independent soil technicians and Port consultants were tasked with overseeing material delivery, placement, and compliance testing throughout the project.

This document is a technical laboratory reference table listing method detection limits (MDLs), practical quantitation levels (PQLs), and published water quality values for a wide range of chemical compounds in various water matrices, including wastewater, groundwater, and drinking water. It compares laboratory PQL ranges against Method B groundwater and surface water standards for chemicals such as acenaphthene, acrolein, aldrin, arsenic, benzene, and PCB compounds. The table is used to assess whether analytical detection capabilities meet regulatory thresholds for water quality monitoring purposes.

This technical document describes the background water chemistry and modeling assumptions used to estimate how metals move through soil and groundwater at contaminated sites. It outlines key simplifications in the MINTEQ geochemical model, including the assumption of chemical equilibrium and the exclusion of redox potential, and presents soil-sorption values (Kd) for various metals such as arsenic, chromium, and cadmium that vary with soil pH. The results show that metal mobility is most strongly influenced by pH levels in the subsurface environment.

This document presents three-phase back calculations for soil contamination levels at a site, listing various chemical constituents including heavy metals (arsenic, cadmium, chromium, lead, mercury, zinc) and petroleum products (TPH, gasoline, heavy oils). The table compares cleanup criteria from multiple regulatory frameworks including ambient water quality criteria (AWQC), drinking water standards, Model Toxics Control Act (MTCA) methods, and Fish and Wildlife Service ecological screening levels. The calculations were used to evaluate soil remediation thresholds based on leaching potential and ecological risk, with source references including EPA and MTCA SSL tables dated August 2001.
