. As discussed in Chapter 1, the integration effort grew out of investigations begun in 1994 to map radionuclide distributions around and beneath the single-shell tanks in the SX Tank Farm in the 200 Area at the site (see Chapter 2~.2 These investigations suggested that significant radionuclide migration into the deep vadose zone had occurred and that radionuclides had in fact reached groundwater in at least one instance.

41 The Integration Project was overlaid onto these three existing organizations, and it was charged with coordinating the activities of these organizations with respect to investigations of the vadose zone, groundwater, and Columbia River.3 The three organizations signed a memorandum of understanding in 1997 that outlined their responsibilities for the vadose zone at the site. The Environmental Restoration Program was directed to be the lead in this effort, and its contractor, Bechtel Hanford, was directed to take the lead in developing a plan of work.

1-2~: To ensure that Hanford Site decisions are defensible and possess an integrated perspective for the protection of water resources, the Columbia River environment, riverdependent life, and users of the Columbia River resources, the mission of the GroundwaterNadose Zone Project is to develop and conduct defensible assessments of the Hanford Site's present and postclosure cumulative effects of radioactive and chemical materials that have accumulated throughout Hanford's history (and which continue to accumulate)

2. The Vadose Zone Technical Element supports studies to develop a better understanding of subsurface contaminant behavior in the vadose zone for example, studies to improve the understanding of fate and transport processes in the vadose zone, studies to improve conceptual and numerical models of contaminant fate and transport in the vadose zone, and studies to test advanced characterization tools and methods.

4. The Columbia River Technical Element supports studies to provide an enhanced understanding of the potential impacts and consequences of contaminant releases to the Columbia River for example, studies to improve conceptual models of the river, studies to parameterize fate and transport models, and studies to improve the understanding of the effects of contaminants on riverine biota.

In fiscal year 1999, DOE held additional meetings with staff from the DOE Center for Risk Excellence, national laboratory and university scientists, Tribal Nations, and other stakeholders to develop a roadmap for the Risk Technical Element. This roadmap and updated roadmaps for the other four technical elements are provided in "Rev.

The Integration Project Roadmap identifies projects that provide R&D support to five Hanford Site core projects as well as two Integration Project efforts: · The Tank Farm Vadose Zone Project (core project) is responsible for remediating or stabilizing contaminants in the vadose zone beneath the 200 Area tank farms.

The Integration Project also provides direct funding for shorter-term, applied R&D work. Some additional R&D may be funded directly by the national laboratories through laboratorydirected research and development funds.8 R&D work, whether under the auspices of the Environmental Management Science Program or the Integration Project, may be conducted in conjunction with core project activities.

DISCUSSION This chapter provides an overview of the Integration Project to set the stage for the detailed assessments of the science and technology plan in subsequent chapters. The material in this chapter reflects the committee's understanding of the Integration Project's S&T program as it existed when the committee completed its information gathering in late March 2001.
