TagThird Runway(1084)

This document presents chemical composition data for various petroleum fuel types, including fresh gasoline, weathered gasoline, fresh diesel, weathered diesel, and heavy fuel oil. It breaks down the percentage and concentration (mg/kg) of aliphatic and aromatic hydrocarbon fractions across different carbon chain length ranges. The data appears to support environmental modeling and site assessment work, likely related to fuel spill or contamination analysis.

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.
