“…The elevation of the SRS ranges from 80 ft above mean sea level (msl) (24 m msl) at the Savannah River to about 400 ft-msl (122 m msl) in the upper northwest portion of the site (USGS, 1987). The Pleistocene Coastal terraces and the Aiken Plateau form two distinct physiographic subregions at the SRS (McAllister et al, 1996). The Pleistocene Coastal terraces are below 270 ft-msl (82 m msl) in elevation, with the lowest terrace constituting the present flood plain along the Savannah River and the higher terraces characterized by gently rolling terrain.…”

The primary objective of this report is to provide an update to the report prepared by Phifer et al. (2006) on the hydraulic property estimates for the soils, cementitious materials, and waste zones associated with the E-Area Low-Level Waste Facility (LLWF). Phifer et al. (2006) also addressed properties for the Z-Area Saltstone Disposal Facility (SDF). However, this report only addresses updates for the portions relevant to E-Area and therefore references to Z-Area have been removed. Therefore, this report supersedes (Phifer et al., 2006).These hydraulic property estimates will be used as input to deterministic, sensitivity, and uncertainty modeling conducted to support the Performance Assessments (PA) for the E-Area LLWF. The hydraulic properties provided for each of the E-Area material zones include: porosity (η), dry bulk density (ρb), particle density (ρp), saturated hydraulic conductivity (Ksat), characteristic curves (suction head, saturation, and relative permeability), and effective diffusion coefficient (De). Nominal or "best estimate" values are provided for use in the deterministic modeling, and representations of the value uncertainty are provided for use in sensitivity and uncertainty modeling efforts.

“…The ecological data were clearly the most difficult to locate.We use the Idaho National Engineering and Environmental Laboratory (INEEL) site and species of concern as an illustration. McAllister et al (1996) list five federal candidates as species of concern: Townsend's big-eared bat; the pygmy rabbit; the ferruginous hawk; the loggerhead shrike; and the northern goshawk.Two endangered species, the bald eagle and the peregrine falcon, are also listed. Four raptor species are considered "sensitive" by the Bureau of Land Management: Swainson's hawk; the merlin; the gyrfalcon; and the burrowing owl.…”

INTRODUCTIONDuring the last three decades, globalization of the world economy has led to the closing of tens of thousands of manufacturing facilities in North America, Europe, and other parts of the world (Ayres, 1998). Massive steel mills, transportation, chemical, and electrical equipment complexes, once the breadwinners for their communities, have become unproductive eyesores waiting for remediation and reuse. In the United States, some are National Priority List (Superfund) sites, others are state equivalents of Superfund sites, and the vast majority are among hundreds of thousands of brownfields sites, some of which are seriously contaminated. Remediation and reuse is a common challenge facing the managers and owners of all these sites, as well as the mayors of the host and nearby communities (U.S. Conference of Mayors, 2000).Oil companies, electrical utilities, the U.S. Departments of Defense and Energy, and other private and public organizations would like to turn surplus land into productive uses.The U.S. Department of Energy (DOE) arguably faces the most daunting challenge because it developed, tested, and built nuclear weapons.To accomplish its national security mission, over a hundred sites and 3,750 square miles of land (about the size of Rhode Island and Delaware combined) were used by the federal government and its contractors and have become an environmental legacy. Since 1989, this land has cost the national government over $60 billion to manage (U.S. Department of Energy [DOE], 1995;Top-to-Bottom, 2002).While many billions of additional dollars will be needed to manage the legacy, DOE has begun a process to reuse parcels of land that were not contaminated, have been remediated to the extent that they do not pose an unacceptable risk, or will be remediated.This process, which DOE calls "risk-based end-state plan- (DOE, 2002a). Given the size, location, and surrounding uses of many DOE sites, ecologically based activities, including wood harvesting, cattle grazing, boating, hunting, bird watching, hiking, and others are candidate end-state options at many sites. At some sites, ecologically based options may be the only possibility because of continuing national security concerns and fear of direct long-term human exposure to residual hazards. An important goal is to remediate appropriately for these residual hazards, but not to the point of being more destructive to ecosystems than leaving contaminants.Across the DOE complex of sites, an enormous amount of data has been gathered that can be used to help assess the advantages and disadvantages of ecologically based land uses and accompanying remediation strategies.The amount of information is voluminous, including the Baseline Environmental Management Report of 1995 and its follow-ups; the stewardship series; environmental impact statements; land management plans; the paths to closure series; environmental assessments; ecological reports;Web pages; and public affairs links (DOE, 1995(DOE, , 1996(DOE, , 2000(DOE, , 2001. Indeed, like many large...
