Evaluates USCOE and Boeing Company sampling data for contaminants including Total DDT (max 14 ppb), Total PCB (max 160 ppb), PAHs (max 459 ppb), and Mercury (max 0.51 ppm) against PSDDA screening levels and Draft MTCA Method A Residential cleanup levels. Concludes Hamm Creek material is suitable for third runway fill under MTCA, though it does not meet PSDDA requirements for open water disposal.
