Outstanding Title by Choice Magazine On the banks of the Pacific Northwest s greatest river lies the Hanford nuclear reservation, an industrial site that appears to be at odds with the surrounding vineyards and desert. The 586-square-mile compound on the Columbia River is known both for its origins as part of the Manhattan Project, which made the first atomic bombs, and for the monumental effort now under way to clean up forty-five years of waste from manufacturing plutonium for nuclear weapons. Hanford routinely makes the news, as scientists, litigants, administrators, and politicians argue over its past and its future. It is easy to think about Hanford as an expression of federal power, a place apart from humanity and nature, but that view distorts its history. Atomic Frontier Days looks through a wider lens, telling a complex story of production, community building, politics, and environmental sensibilities. In brilliantly structured parallel stories, the authors bridge the divisions that accompany Hanford s headlines and offer perspective on today s controversies. Influenced as much by regional culture, economics, and politics as by war, diplomacy, and environmentalism, Hanford and the Tri-Cities of Richland, Pasco, and Kennewick illuminate the history of the modern American West.

For more than four decades beginning in 1944, the Hanford nuclear weapons facility in southeastern Washington State secretly blanketed much of the Pacific Northwest with low-dose ionizing radiation, the byproduct of plutonium production. For those who lived in the vicinity, many of them families of Hanford workers, the consequences soon became apparent as rates of illness and death steadily climbed-despite repeated assurances from the Atomic Energy Commission that the facility posed no threat. Trisha T. Pritikin, who has battled a lifetime of debilitating illness to become a lawyer and advocate for her fellow \"downwinders,\" tells the devastating story of those who were harmed in Hanford's wake and, seeking answers and justice, were subjected to yet more suffering. At the center of The Hanford Plaintiffs are the oral histories of twenty-four people who joined In re Hanford Nuclear Reservation Litigation , the class-action suit that sought recognition of, and recompense for, the grievous injury knowingly caused by Hanford. Radioactive contamination of American communities was not uncommon during the wartime Manhattan Project, nor during the Cold War nuclear buildup that followed. Pritikin interweaves the stories of people poisoned by Hanford with a parallel account of civilians downwind of the Nevada atomic test site, who suffer from identical radiogenic diseases. Against the heartrending details of personal illness and loss and, ultimately, persistence in the face of a legal system that protects the government on all fronts and at all costs, The Hanford Plaintiffs draws a damning picture of the failure of the US Congress and the Judiciary to defend the American public and to adequately redress a catastrophic wrong. Documenting the legal, medical, and human cost of one community's struggle for justice, this book conveys in clear and urgent terms the damage done to ordinary Americans in the name of business, progress, and patriotism.

Perhaps the first environmental engineer at Hanford, Melvin R. Adams spent a career sifting through Hanford's rubble, abandoned documents, factories, and tools. His thoughtful, written vignettes recall challenges and sites he worked on or found personally intriguing. In the process, he offers some surprising revelations and perspectives on controversial matters. A 2016 ForeWord Magazine Top Ten University Pick.

Spatial turnover in the composition of biological communities is governed by (ecological) Drift, Selection and Dispersal. Commonly applied statistical tools cannot quantitatively estimate these processes, nor identify abiotic features that impose these processes. For interrogation of subsurface microbial communities distributed across two geologically distinct formations of the unconfined aquifer underlying the Hanford Site in southeastern Washington State, we developed an analytical framework that advances ecological understanding in two primary ways. First, we quantitatively estimate influences of Drift, Selection and Dispersal. Second, ecological patterns are used to characterize measured and unmeasured abiotic variables that impose Selection or that result in low levels of Dispersal. We find that (i) Drift alone consistently governs ∼25% of spatial turnover in community composition; (ii) in deeper, finer-grained sediments, Selection is strong (governing ∼60% of turnover), being imposed by an unmeasured but spatially structured environmental variable; (iii) in shallower, coarser-grained sediments, Selection is weaker (governing ∼30% of turnover), being imposed by vertically and horizontally structured hydrological factors;(iv) low levels of Dispersal can govern nearly 30% of turnover and be caused primarily by spatial isolation resulting from limited exchange between finer and coarser-grain sediments; and (v) highly permeable sediments are associated with high levels of Dispersal that homogenize community composition and govern over 20% of turnover. We further show that our framework provides inferences that cannot be achieved using preexisting approaches, and suggest that their broad application will facilitate a unified understanding of microbial communities.

A major issue in the cleanup of this country's nuclear weapons complex is how to dispose of the radioactive waste resulting primarily from the chemical processing operations for the recovery of plutonium and other defense strategic nuclear materials. The wastes are stored in hundreds of large underground tanks at four U.S. Department of Energy (DOE) sites throughout the United States. The tanks contain hundreds of thousands of cubic meters of radioactive and hazardous waste. Most of it is high-level waste (HLW), some of it is transuranic (TRU) or low- level waste (LLW), and essentially all containing significant amounts of chemicals deemed hazardous. Of the 278 tanks involved, about 70 are known or assumed to have leaked some of their contents to the environment. The remediation of the tanks and their contents requires the development of new technologies to enable cleanup and minimize costs while meeting various health, safety, and environmental objectives. While DOE has a process based on stakeholder participation for screening and formulating technology needs, it lacks transparency (in terms of being apparent to all concerned decision makers and other interested parties) and a systematic basis (in terms of identifying end states for the contaminants and developing pathways to these states from the present conditions). An End State Methodology for Identifying Technology Needs for Environmental Management, with an Example from the Hanford Site Tanks describes an approach for identifying technology development needs that is both systematic and transparent to enhance the cleanup and remediation of the tank contents and their sites. The authoring committee believes that the recommended end state based approach can be applied to DOE waste management in general, not just to waste in tanks. The approach is illustrated through an example based on the tanks at the DOE Hanford Site in southeastern Washington state, the location of some 60 percent by volume of the tank waste residues.

A growing body of research supports widespread future reliance on apatite for radioactive waste cleanup. Apatite is a multi-functional radionuclide sorbent that lowers dissolved radionuclide concentrations by surface sorption, ion exchange, surface precipitation, and by providing phosphate to precipitate low-solubility radionuclide-containing minerals. Natural apatites are rich in trace elements, and apatite's stability in the geologic record suggest that radionuclides incorporated into apatite, whether in a permeable reactive barrier or a waste form, are likely to remain isolated from the biosphere for long periods of time. Here we outline the mineralogic and surface origins of apatite-radionuclide reactivity and show how apatites might be used to environmental advantage in the future.

This study explores field‐scale modeling of U(VI) reactive transport through incorporation of laboratory and field data. A field‐scale reactive transport model was developed on the basis of laboratory‐characterized U(VI) surface complexation reactions (SCRs) and multirate mass transfer processes, as well as field‐measured hydrogeochemical conditions at the U.S. Department of Energy, Hanford 300 Area (300 A), Washington. The model was used to assess the importance of multirate mass transfer processes on U(VI) reactive transport and to evaluate the effect of variable geochemical conditions caused by dynamic river water‐groundwater interactions on U(VI) plume migration. Model simulations revealed complex spatiotemporal relationships between groundwater composition and U(VI) speciation, adsorption, and plume migration. In general, river water intrusion enhances uranium adsorption and lowers aqueous uranium concentration because river water dilution increases pH and decreases aqueous bicarbonate concentration, leading to overall enhanced U(VI) surface complexation. Strong U(VI) retardation was computed for the field‐measured hydrogeochemical conditions, suggesting a slow dissipation of the U(VI) plume, a phenomenon consistent with field observations. The simulations also showed that SCR‐retarded U(VI) migration becomes more dynamic and synchronous with the groundwater flow field when multirate mass transfer processes are involved. Breakthrough curves at selected locations and the temporal changes in the calculated mass during the 20 year simulation period indicated that uranium adsorption/desorption never attained steady state because of the dynamic flow field and groundwater composition variations caused by river water intrusion. Thus, the multirate SCR model appears to be a crucial consideration for future reactive transport simulations of uranium contaminants at the Hanford 300 A site and elsewhere under similar hydrogeochemical conditions.

The deep vadose zone (DVZ) lies below the depth where practical and cost-effective removal of contaminants through open excavation is feasible. In situ grouting is a potential approach to immobilize contaminants and prevent their spread into groundwater aquifers. Polyurethane and epoxy-based grouting resins have low viscosities, enabling them to infiltrate low-hydraulic conductivity soils commonly found in the DVZ. When these resins cure, they form a solid polymer grout that effectively fills voids within the soil to decrease soil hydraulic conductivity and diffusivity, which limits contaminant transport. In this study, the performance of three different resin-based materials, polyurethane, polyurethane foam, and epoxy, was evaluated on the basis of decreasing soil porosity, soil hydraulic conductivity, and iodide diffusivity in simulated contaminated soil representative of a DVZ environment. The test results indicate that the iodide leachability index of specimens grouted with these different resins all exceed the value of 6, which fulfills the criteria set by the U.S. Nuclear Regulatory Commission (NRC) standard for solid waste intended for shallow burial. All grouted samples demonstrate an exponential relationship between porosity and diffusivity that aligns with Archie’s rule, where samples with lower porosity tend to exhibit lower diffusivity. The minimum porosity of grouted soil obtained is 5.1%, and the minimum iodide diffusivity recorded is 2.11 × 10⁻⁸ cm 2 /s. The results also show that lower soil water content leads to lower porosity, diffusivity, and hydraulic conductivity in polyurethane grouted samples. The findings from this study provide valuable guidance for the use of polyurethane and epoxy grouting in limiting contaminant transport in DVZ environments.

The primary purpose of systems engineering is to organize information and knowledge to assist those who manage, direct, and control the planning, development, production, and operation of the systems necessary to accomplish a given mission. However, this purpose can be compromised or defeated if information production and organization becomes an end unto itself. Systems engineering was developed to help resolve the engineering problems that are encountered when attempting to develop and implement large and complex engineering projects. It depends upon integrated program planning and development, disciplined and consistent allocation and control of design and development requirements and functions, and systems analysis. The key thesis of this report is that proper application of systems analysis and systems engineering will improve the management of tank wastes at the Hanford Site significantly, thereby leading to reduced life cycle costs for remediation and more effective risk reduction. The committee recognizes that evidence for cost savings from application of systems engineering has not been demonstrated yet.
