ECOLOGY, HYDROLOGY, SITE ENVIRONMENT

OU developed expedited field survey and sampling techniques for PCB congeners and dioxins; developed an approach for graphical information system mapping of PCB congener and dioxin occurrence in sediment and soil; and conducted a preliminary assessment of PCB congener and dioxin presence and fate, including geochemical transformation (i.e., “aging”), in sediments and soil at the PORTS site. This project used an appropriate location, such as the X-533 Switch Yard, as a test bed for the expedited survey and sampling techniques. The expedited sampling and analytical technique was verified using split-sample results from a qualified third-party laboratory. The information developed was summarized in draft and final reports and be made available as an electronic database. In addition, OU conducted briefings with OEPA as part of this project to explain the methods developed and encouraged the use of results from field sampling techniques in environmental decision-making at the PORTS site. OU ensured that OEPA is pursued as a Task Team member for this task.
